Full textIn this work, speaker characteristic modeling has been applied in the fields of automatic speech recognition (ASR) and automatic speaker verification (ASV). In ASR, a key problem is that acoustic mismatch between training and test conditions degrade classification per- formance. In this work, a child exemplifies a speaker not represented in training data and methods to reduce the spectral mismatch are devised and evaluated. To reduce the acoustic mismatch, predictive modeling based on spectral speech transformation is applied. Follow- ing this approach, a model suitable for a target speaker, not well represented in the training data, is estimated and synthesized by applying vocal tract predictive modeling (VTPM). In this thesis, the traditional static modeling on the utterance level is extended to dynamic modeling. This is accomplished by operating also on sub-utterance units, such as phonemes, phone-realizations, sub-phone realizations and sound frames.
Initial experiments shows that adaptation of an acoustic model trained on adult speech significantly reduced the word error rate of ASR for children, but not to the level of a model trained on children’s speech. Multi-speaker-group training provided an acoustic model that performed recognition for both adults and children within the same model at almost the same accuracy as speaker-group dedicated models, with no added model complexity. In the analysis of the cause of errors, body height of the child was shown to be correlated to word error rate.
A further result is that the computationally demanding iterative recognition process in standard VTLN can be replaced by synthetically extending the vocal tract length distribution in the training data. A multi-warp model is trained on the extended data and recognition is performed in a single pass. The accuracy is similar to that of the standard technique.
A concluding experiment in ASR shows that the word error rate can be reduced by ex- tending a static vocal tract length compensation parameter into a temporal parameter track. A key component to reach this improvement was provided by a novel joint two-level opti- mization process. In the process, the track was determined as a composition of a static and a dynamic component, which were simultaneously optimized on the utterance and sub- utterance level respectively. This had the principal advantage of limiting the modulation am- plitude of the track to what is realistic for an individual speaker. The recognition error rate was reduced by 10% relative compared with that of a standard utterance-specific estimation technique.
The techniques devised and evaluated can also be applied to other speaker characteristic properties, which exhibit a dynamic nature.
An excursion into ASV led to the proposal of a statistical speaker population model. The model represents an alternative approach for determining the reject/accept threshold in an ASV system instead of the commonly used direct estimation on a set of client and impos- tor utterances. This is especially valuable in applications where a low false reject or false ac- cept rate is required. In these cases, the number of errors is often too few to estimate a reli- able threshold using the direct method. The results are encouraging but need to be verified on a larger database.

This thesis presents an integrated framework and implementation for Mertz, an expressive robotic creature for exploring the task of face recognition through natural interaction in an incremental and unsupervised fashion. The goal of this thesis is to advance toward a framework which would allow robots to incrementally "get to know" a set of familiar individuals in a natural and extendable way. This thesis is motivated by the increasingly popular goal of integrating robots in the home. In order to be effective in human-centric tasks, the robots must be able to not only recognize each family member, but also to learn about the roles of various people in the household. In this thesis, we focus on two particular limitations of the current technology. Firstly, most of face recognition research concentrate on the supervised classification problem. Currently, one of the biggest problems in face recognition is how to generalize the system to be able to recognize new test data that vary from the training data. Thus, until this problem is solved completely, the existing supervised approaches may require multiple manual introduction and labelling sessions to include training data with enough variations. Secondly, there is typically a large gap between research prototypes and commercial products, largely due to lack of robustness and scalability to different environmental settings.
(cont.) In this thesis, we propose an unsupervised approach which would allow for a more adaptive system which can incrementally update the training set with more recent data or new individuals over time. Moreover, it gives the robots a more natural social recognition mechanism to learn not only to recognize each person's appearance, but also to remember some relevant contextual information that the robot observed during previous interaction sessions. Therefore, this thesis focuses on integrating an unsupervised and incremental face recognition system within a physical robot which interfaces directly with humans through natural social interaction. The robot autonomously detects, tracks, and segments face images during these interactions and automatically generates a training set for its face recognition system. Moreover, in order to motivate robust solutions and address scalability issues, we chose to put the robot, Mertz, in unstructured public environments to interact with naive passersby, instead of with only the researchers within the laboratory environment. While an unsupervised and incremental face recognition system is a crucial element toward our target goal, it is only a part of the story. A face recognition system typically receives either pre-recorded face images or a streaming video from a static camera.
(cont.) As illustrated an ACLU review of a commercial face recognition installation, a security application which interfaces with the latter is already very challenging. In this case, our target goal is a robot that can recognize people in a home setting. The interface between robots and humans is even more dynamic. Both the robots and the humans move around. We present the robot implementation and its unsupervised incremental face recognition framework. We describe an algorithm for clustering local features extracted from a large set of automatically generated face data. We demonstrate the robot's capabilities and limitations in a series of experiments at a public lobby. In a final experiment, the robot interacted with a few hundred individuals in an eight day period and generated a training set of over a hundred thousand face images. We evaluate the clustering algorithm performance across a range of parameters on this automatically generated training data and also the Honda-UCSD video face database. Lastly, we present some recognition results using the self-labelled clusters.

Full textIndividual differences in perceiving, learning, and recognizing faces were shown on the behavioral and neural level but were rarely related to one another. By determining relationships between behavioral and neurocognitive indicators of face cognition, brain systems and neural sub-processes can be identified that underlie individual variations on the behavioral level. The present dissertation laid the foundation for using event-related potentials (ERPs) as neurocognitive indicators in individual differences research. ERP components were shown to possess the same high psychometric qualities as behavioral ability measures and thus to measure individual differences of neural processing reliably and stably across time. On the behavioral level, three component abilities of face cognition were established: face perception, face memory, and the speed of face cognition. ERP components were used in structural equation models that estimated contributions of neurocognitive indicators to the individual differences in these face cognition abilities. Regression analysis was used to determine the contributions of P100, N170, the so called difference due to memory (Dm), as well as early and late repetition effects (ERE and LRE) to face cognition abilities in 85 participants. Certain amounts of variance in face cognition as seen on the behavioral level were accounted for by individual differences in the temporal dimension of structural encoding of a face (N170 latency) and in the re-activation of both stored facial structures (ERE) and person-identity information (LRE). In contrast, processes of early vision (P100), the neural activation of structural face encoding (N170 amplitude), and memory encoding of new faces (Dm) did not show any contribution to individual differences in face cognition. These findings show that individual differences in face cognition depend on the speed of structurally encoding faces and on the efficiency and speed of accessing face and person memory.

Academics, victims, and advocates have increasingly brought attention to the need for programs and policies to protect and shelter nonhuman victims of domestic violence. Research focused on the “Link” between human-based violence and violence against animals has played a significant role in the creation of these programs, and has prompted a more holistic approach to providing services to all victimized family members. In this dissertation, I focus on the unique origin points of several animal-friendly domestic violence organizations and the models used to serve both human and nonhuman victims, as well as on the individual advocacy and activism of animal-friendly domestic violence organization workers. Data collection from semi-structured interviews with thirty domestic violence workers and advocates provides the foundation for my investigation of the importance of community networks and individual identity as a source of professional navigation of the connected spheres of domestic violence and animal abuse. This study extends the ever-growing collection of research on the “Link” and on the broader discipline of human-animal studies. Finally, this research provides an additional perspective on the use of personal and collective identity to engage in advocacy on behalf of nonhuman victims of domestic violence.

Full textIn humans, voice conveys heterogeneous information such as speaker’s identity, which can be automatically extracted even when language content and emotional state vary. We hypothesized that the ability to recognize a speaker considerably varied across the population, as previously observed for face recognition. To test this hypothesis, a short voice recognition test was delivered to 1120 subjects in order to observe how voice recognition abilities were distributed in the general population. Since it has been previously observed that there exists a considerable inter-individual variability in voice-elicited activity in temporal voice areas (TVAs), regions along the superior temporal sulcus/gyrus (STS/STG) that show preferentially activation for voices than other sounds, the second aim of this work was then to better characterize the link between the behavioral and neural mechanisms underlying inter-individual variability in voice recognition processes through functional magnetic resonance imaging (fMRI). The results of a first fMRI study showed that functional connectivity between frontal and temporal voice sensitive regions increased with voice recognition scores obtained at a voice recognition test. Another fMRI study showed that speaker’s identity was treated in an extended network of regions, including TVAs but also frontal regions and that voice/non-voice classification accuracy in right STS increased with speaker identification abilities. Altogether, these results suggest that voice recognition abilities considerably vary across subjects and that this variability can be mirrored by different neural profiles within the voice perception network

Full textCommunication is a fundamental process that allows animals to effectively transfer information between groups or individuals. Recognition plays an essential role in permitting animals to distinguish individuals based upon both communicatory and non-communicatory signals allowing animals to direct suitable behaviours towards them. Several modes of recognition exist and in colonial breeding animals which congregate in large numbers, acoustic signalling is thought to be the most effective as it suffers less from environmental degradation. Otariid seals (fur seals and sea lions) are generally colonial breeding species which congregate at high densities on offshore islands. In contrast to the other Arctocephaline species, the Australian fur seal, Arctocephalus pusillus doriferus, along with its conspecific, the Cape fur seal, A. p. pusillus, display many of the behavioural traits of sea lions. This may have important consequences in terms of its social structure and evolution. The acoustic communication of Australian fur seals was studied on Kanowna Island, Bass Strait, Australia. Analysing the acoustic structure of vocalisations and their use facilitates our understanding of the social function of calls in animal communication. The vocal repertoires of males, females, pups and yearlings were characterised and their behavioural context examined. Call structural variations in males were evident with changes in behavioural context, indicating parallel changes in the emotive state of sender. For a call to be used in vocal recognition it must display stereotypy within callers and variation between them. In Australian fur seal females and pups, individuals were found to have unique calls. Mutual mother-pup recognition has been suggested for otariids and this study supports the potential for this process to occur through the use of vocalisations. Call structural changes in pup vocalisations were also investigated over the progression of the year, from birth to weaning. Vocalisations produced by pups increased in duration, lowered in both the number of parts per call and the harmonic band containing the maximum frequency as they became older, suggesting calls are changing constantly as pups grow toward maturity. It has been suggested through descriptive reports, that the bark call produced by males is important to vocal recognition. The present study quantified this through the analysis of vocalisations produced by male Australian fur seals. Results support descriptive evidence suggesting that male barks can be used to discriminate callers. Traditional playback studies further confirmed that territorial male Australian fur seals respond significantly more to the calls of strangers than to those of neighbours, supporting male vocal recognition. This study modified call features of the bark to determine the importance to vocal recognition. The results indicate that the whole frequency spectrum was important to recognition. There was also an increase in response from males when they heard more bark units, indicating the importance of repetition by a caller. Recognition occurred when males heard between 25-75% of each bark unit, indicating that the whole duration of each bark unit is not necessary for recognition to occur. This may have particular advantages for communication in acoustically complex breeding environments, where parts of calls may be degraded by the environment. The present study examined the life history characteristics of otariids to determine the factors likely to influence and shape its vocal behaviour. Preliminary results indicate that female density, body size and the breeding environment all influence the vocal behaviour of otariids, while duration of lactation and the degree of polygyny do not appear to be influential. Understanding these interactions may help elucidate how vocal recognition and communication have evolved in different pinniped species.

Full textRecognition plays an important role in animal communication systems and individuals often employ different sensory modalities to enact this activity. Although recognition has been widely investigated, especially for mother-offspring interactions, there is a dearth of information about multimodal recognition and the relative importance and interactions of various sensory cues. In this thesis, I explored multimodal communication in a colonial mammal – the Australian sea lion (Neophoca cinerea). Communication during mother-pup reunions is known to be multimodal in this species, yet the underlying processes of olfactory and visual recognition, as well as the interactions between acoustic, visual and olfactory cues remain unclear. Through chemical analyses, I determined whether chemical profiles differ among sex and age classes, colonies, and body regions of animals. Chemical similarities between mothers and pups indicate that phenotype matching may be used by Australian sea lions for olfactory recognition. I examined the role of visual cues in mother-pup recognition and found that age-specific visual cues assist mothers to refine their search for their offspring in the colony. Pups are capable of distinguishing various visual cues that can be used in the assessment of conspecifics. Having provided baseline information about the role of sensory cues in isolation, I determined how acoustic, olfactory, and visual cues are used in a synergistic way to ensure accurate mutual recognition and then interpreted the results using a cost-benefit perspective to disentangle the evolutionary pressures on each component of this communication system. I showed that although cues have the ability to convey given information in isolation, their role may be different when other sensory cues are present. Furthermore, there is a mutual dependency in the communication system, where the limitations imposed on one participant of the dyad affect cue use by the other. These findings contribute to a better understanding of mammal mother-offspring recognition and communication mechanisms in vertebrates

Full textEsta pesquisa propõe uma metodologia para melhorar previsões calculadas por um modelo de regressão, sem a necessidade de modificar seus parâmetros ou sua arquitetura. Em outras palavras, o objetivo é obter melhores resultados por meio de ajustes nos valores computados pela regressão, sem alterar ou reconstruir o modelo de previsão original. A proposta é ajustar os valores previstos pela regressão por meio do uso de estimadores de confiabilidade individuais capazes de indicar se um determinado valor estimado é propenso a produzir um erro considerado crítico pelo usuário da regressão. O método proposto foi testado em três conjuntos de experimentos utilizando três tipos de dados diferentes. O primeiro conjunto de experimentos trabalhou com dados produzidos artificialmente, o segundo, com dados transversais extraídos no repositório público de dados UCI Machine Learning Repository, e o terceiro, com dados do tipo séries de tempos extraídos do ISO-NE (Independent System Operator in New England). Os experimentos com dados artificiais foram executados para verificar o comportamento do método em situações controladas. Nesse caso, os experimentos alcançaram melhores resultados para dados limpos artificialmente produzidos e evidenciaram progressiva piora com a adição de elementos aleatórios. Os experimentos com dados reais extraído das bases de dados UCI e ISO-NE foram realizados para investigar a aplicabilidade da metodologia no mundo real. O método proposto foi capaz de melhorar os valores previstos por regressões em cerca de 95% dos experimentos realizados com dados reais.

Full textO presente trabalho procura destacar o olhar de Rousseau a respeito do indivÃduo moderno. No entanto, para muitos leitores e estudiosos de Rousseau, esta questÃo nÃo temnenhum destaque nas obras do pensador genebrino. à uma questÃo que nÃo interessa à filosofia roussseauniana, e, a prova disto, à que boa parte dos intÃrpretes apontam que o centro desta filosofia gira em torno da importÃncia da vida republicana. Aqui, o contrÃrio à o que vigora. Admite-se que a grande questÃo que envolve o pensamento rousseauniano se dà em torno dos problemas enfrentados pelos indivÃduos, que sÃo decorrentes da evoluÃÃo da sociedade moderna. A sociedade moderna propiciou o desenvolvimento e o progresso das ciÃncias. Este contexto para Rousseau fez com que os problemas dos indivÃduos se agravassem, ao invÃs de serem solucionados. As estruturas da sociedade moderna levaram os indivÃduos a terem bloqueadas a sua possibilidade de realizaÃÃo; algo que Rousseau tenta sanar em sua reflexÃo sobre o mundo moderno, sobre os indivÃduos. Na sua concepÃÃo, a chave para a formulaÃÃo de respostas aos problemas do indivÃduo moderno se encontram na possibilidade de reconhecimento do indivÃduo, como uma forma de realizaÃÃo. à medida em que o indivÃduo à reconhecido, hà a possibilidade de realizaÃÃo deste mesmo indivÃduo. A realizaÃÃo como reconhecimento sà poderà ocorrer dentro de um contexto especÃfico, que para Rousseau à o contexto da repÃblica. à a repÃblica o espaÃo no qual o indivÃduo deve construir para que seja possÃvel a sua realizaÃÃo. Tal realizaÃÃo se efetiva na medida em que o indivÃduo tem preservada a sua constituiÃÃo mais profunda, que se sustenta com o sentimento de existÃnciaprimeiro, o amor-de-si. A possibilidade de realizaÃÃo enquanto reconhecimento sà se torna viÃvel para o indivÃduo na proporÃÃo em que ele tem garantida a sua plena constituiÃÃo. Enquanto indivÃduo, que à o agente da construÃÃo de uma repÃblica que o acolhe enquantocidadÃo e que tem em suas mÃos a possibilidade de ser um artÃfice da construÃÃo do pacto republicano. Desta forma, Rousseau se insere numa tradiÃÃo importante, que tem no indivÃduosua grande preocupaÃÃo.

Full textThis work wants to bring definitions and clarifications about the artists working in the cabarets of Toulouse. In order to discern the “processes of legitimization” the artists struggle to assert their social, cultural, artistic, professional legitimacy.Due to the mystery which floats around these workers’ status, their way of life, their timetable, their rituals and codes, their organization in networks, their social circles and their atypical careers, people have a tendency to put the label of “particular”, “different”, “bohemian” on them. So, on the basis of the prejudices and on the predominant stereotypes, we can wonder how these artists of music-hall can justify their activities, their status in comparison with the order arts and especially how they succeed in exporting their legitimacy in other relational spheres. The hypothesis shows that the legitimacy of the artists of the cabaret in Toulouse is neither acquired nor assured in any circles.It is also a question of assessing the cultural legitimacy of this group among the other arts. These professional artists propose shows in live and we can wonder what place they have in the hierarchy of art, noticing that arts turned out to be structured by conflicts of values. Based on the principle of intra-individual variations, we can debate about “Cultural Democracy” and the hierarchies of cultural values, and so reveal the legitimacy of “the arts of entertainment”.This work is an ethnosociological survey, in which the researcher is involved in, and he denounces the social problems he experiences in his daily life

Full textThe doctoral investigation presented here explores the issue of personal and community identity through the category of recognition. Our main objective consists of rethinking these concepts in a way that guards the plurality of significance that each one shelters, at the same time seeking to evaluate as much the political depth of the self as its relational structure. Both concepts - identity and recognition - contain some kind of link with otherness, with the notion of other that transforms the individual’s perception of self. But these concepts also shelter a base of perplexity and strangeness relative to the internal world of the citizen. Our main hypothesis is that this interiority of self is, partly, a public and political phenomenon. This hypothesis requires implementing a theoretical matrix open to transcending the logical-verbal structures of thought with which the issue of identity recognition is usually addressed, starting with the lexicon of “objective” and “subjective”, the extreme division of “what is public” and “what is private”, between the “inside” and “outside”.

Full textThe youth of South Africa is currently faced with high levels of unemployment and poverty. This raises concerns about the future of the South African people and its economy. Consequently, much is needed to develop the youth to allow for a prosperous future. A decrease in poverty and unemployment was found to be linked to an increase in education. Entrepreneurial education can have a significant impact on entrepreneurial success. This research paper aims to assess the influence of entrepreneurial education and training on students' entrepreneurial development. To ensure a comprehensive assessment of the development of students, I utilised a mixed methodology to assess students both quantitatively and qualitatively. The study assessed a sample of students from South Africa and the United States of America who jointly partook in a two-week entrepreneurial education and training programme at TSiBA Education, Cape Town, South Africa. Entrepreneurial education and training had a positive effect on the students' entrepreneurial development, entrepreneurial orientation and intentions to start a business. While entrepreneurial orientation aids the exploitation of business opportunities, before opportunities can be exploited they must be recognised. Bringing into question the link between students' entrepreneurial orientation and their abilities to recognise and develop opportunities into successful ventures. To explore this I interviewed two participants and found the high entrepreneurially orientated participant to exhibit greater opportunity recognition and development abilities, compared to the low entrepreneurially orientated participant. I concluded by finding that although differences do exist between high and low entrepreneurially orientated students, entrepreneurial education and training could positively influence students' entrepreneurial orientation and assist in the development of entrepreneurs. The results suggest that TSiBA Education should attempt to increase the duration of the entrepreneurial programme to maximize the influence of the entrepreneurial education and training.

The advertisement call of anurans contains spectral and temporal information important for specific recognition, beside relevance in social organization and attraction of females. The variation in features call has been received attention because their importance in breeding behavior, and implications for the recognition of conespecifics in multiple levels of social organization. The objective of this study is to investigate patterns of variability in the acoustics properties of the advertisement call of Dendropsophus cruzi in different levels: individual, population and specific, in ten populations of state of Goiás. The following acoustic variables were analyzed: call repetition rate, duration of call, number of pulses, duration of pulse and dominant frequency. The acoustics parameters weret influenced as for temperature as for rostrumcloacal length (CRC), and presented different variability coefficients, within-male and among-male being the variability among-male greater than the variability within-male. The dominant frequency is the property of greater potential for use in the specific recognition and also is the characteristic that best discriminates populations. The geographic distance did not predict the differences found in the call. However, geographic cline patterns was found for duration of call, call repetition rate and CRC. The differences among populations can be due to local selective pressures as environmental and social structure of the chorus. The decreases of CRC to the north reflect the gradual change in the temperature in the same sense, influencing the development and growth rates, with smaller individuals. On the other hand, the increase of the temporal characters of call occur for increase the loss attractiveness caused by the high dominant frequency imposed by the smallest size of the body.
O canto de anúncio contém informações espectrais e temporais importantes para o reconhecimento específico, além de sua relevância na organização social e atração sexual de fêmeas. A variação nas características do canto tem recebido bastante atenção devido sua importância no comportamento de acasalamento e suas implicações para o reconhecimento de coespecíficos em múltiplos níveis de organização social. Assim o objetivo deste estudo é investigar padrões de variabilidade nos parâmetros acústicos do canto de anúncio de Dendropsophus cruzi em nível individual, populacional e específico, em dez populações do estado de Goiás. As seguintes variáveis acústicas foram analisadas: taxa de repetição, duração do canto, número de pulsos, duração do pulso e frequência dominante. Os parâmetros acústicos foram influenciados tanto pela temperatura como pelo comprimento rostro-cloacal (CRC), e apresentaram diferentes coeficientes de variação, sendo que o CVinter-individual foi maior que o CVintraindividual. A freqüência dominante é a propriedade de maior potencial para ser usada no reconhecimento específico e também é a característica que melhor discrimina as populações. A distância geográfica entre as populações não foi preditora para as diferenças encontradas no canto. Entretanto padrões geográficos clinais foram encontrados para duração do canto, freqüência dominante, taxa de repetição e CRC. As diferenças entre as populações podem ser devidas a pressões seletivas locais tanto ambientais como de estrutura social do coro. A diminuição do CRC ao norte reflete a mudança gradual de temperatura que ocorre nesse sentido, influenciando as taxas de desenvolvimento e crescimento, com indivíduos menores. Por outro lado o aumento das características temporais do canto ocorre para aumentar a atratividade perdida pelas altas freqüências dominantes impostas pelo menor tamanho do corpo.

Full textIt is practically impossible to prevent individuals from choosing the legal framework that would best fit their expectations. Law regulates and limits individual will in contexts in which collective interests, as it understands them, should prevail; the international aspect of a situation relativizes, however, these limits, and offers multiple possibilities for individuals to develop a tailor-made framework for their own relationship. Private international law addresses the difficulties arising from the international aspects of a situation, but the complexity of some cases challenges the limits of the discipline’s mechanisms. Controlling the effects of individual choices becomes more difficult when not only the different content of rules from a country to another is explored, but individual strategy extends also to neighbouring regimes, in a normatively heterogeneous world. The strategic exercise of will consists in the manipulation of the regulatory framework by an individual aiming at excluding the application of a norm which does not satisfy their purpose. The submission of the situation to a chosen legal framework diverts it from the field of vision of the initial legal order, which will not see the situation again unless it is called to decide upon its effects. The new solution developed by the individual risks being not fully anticipated and regulated by the receiving legal order, or by any legal order that will have to decide on matters related to the main situation. Thus, in these conditions, the different interests at stake are not fully considered and balanced. As a space that escapes from an observer’s eyesight, some aspects of the situations are in a blind spot, phenomenon whose description and treatment are at the centre of this thesis

Full textINTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent condition in the general adult population. Also important is its high rate of comorbidity with other psychiatric disorders, particularly bipolar disorder (BD). However, not only the definition of ADHD is still a matter of discussion but also the limits of the ADHD+BD comorbidity; such comorbidity may be interpreted as a continuum spectrum of BD, an overlap of symptoms, or a separate diagnostic entity with a distinct neurobiological substrate. Therefore, further search for valid biomarkers with potential application in clinical practice is still required. The recent development of high-dimensional pattern recognition techniques has allowed targeted investigations of biomarkers, searching for sets of characteristics that could be used to classify each patient in a particular group. OBECTIVES: To apply, for the first time in the literature, machine learning-based pattern recognition methods to neuroimaging data obtained in never-treated adults with childhood-onset ADHD, BD, ADHD+BD and healthy controls (HC), searching for different neuroanatomical signatures associated with each disorder. METHODS: Three groups of never treated adults as following: 67 ADHD patients, 30 BD patients, 16 patients fulfilling diagnostic criteria for both disorders; and a sample of HC (n=66) underwent structural magnetic resonance imaging (MRI) and diffusion magnetic resonance imaging (DTI) acquisitions. A support vector machine (SVM) classifier with non-linear kernel was applied on multi-modal image features extracted on regions-of-interest placed across the whole brain. Comparisons among all patients and controls were carried out through subgroups individually matched for gender and age, and group-matched for years of education and socio-economic status. Diagnostic performance measures were evaluated by computing receiver operating characteristic (ROC) curves. RESULTS: All results on classification analyses were clearly significant above chance level, except in the comparison analysis between BD patients and HC (p=0.09). The comparison between ADHD and HC subgroups afforded area under the curve (AUC) measures and diagnostic accuracy of up to 0.71 and 66.2% (p=0.003). Comparison between ADHD and BD subgroups achieved AUC and diagnostic accuracy of up to 0.78 and 70.2% (p=0.01). Classification analysis between ADHD+BD patients and the other subgroups yielded AUC and diagnostic accuracy values of up to 0.89 and 80.5% (p=0.0009). CONCLUSION: The present study provides neurobiological endorsement to the validity of the clinically-based diagnosis of ADHD in adults. Brain features were strong enough to the differential diagnosis between ADHD and BD, as well as to reinforce the hypothesis that ADHD+BD may represent a distinct neurobiological entity. However, relevant challenges persist regarding the search for biomarkers for BD. The neuroanatomical signatures identified herein may provide additional, objective information, paving the way for future studies assessing its influence in treatment decisions in adults with ADHD and ADHD+BD spectrum symptoms
