This thesis attempts to clarify the need for an appreciation of architecture theory within a computational architectural domain. It reveals and reflects upon some of the cultural, historical and technological contexts that influenced the emergence of a computational practice in architecture. To carry out this new reading, we focus on the pioneering research that underpinned the beginnings of the relationship between architecture and computation and which was carried out at four research Centres both in the UK and in the USA: The Land Use and Built Form Studies [LUBFS], founded at Cambridge, UK; The Center for Configurational Studies at the Open University, Milton Keynes; The Architecture Machine Group [AMG] at MIT, and the Design Research Center [DRC] at Carnegie Mellon University, Pittsburgh, USA. Moreover this thesis reinterprets the role of Leslie Martin as the founding father of LUBFS by showing the influence of the British physicist Desmond Bernal's building science research and the British avant-garde movement on Martin's work. This thesis also presents reflections on how best to use computation in architecture.

School curricula are designed with the expectation that students achieve literacy. They usually support the acquisition of language by encouraging students to learn how to decode information within a sentence. In this thesis it is suggested that literacy skills in children five to seven years of age can be obtained with a broader understanding of language and its representation. Oral storytelling is presented as a way to develop metacognitive skills with a focus on character-based narrative where children must create the perspectives of the characters. The ability to tell stories is common to children from every community and can help them in school performance. Children should therefore be encouraged to express their understanding of character perspectives in oral storytelling. This thesis presents a tangible interface that allows children to practice pre-literacy skills using oral language. It introduces Dolltalk, a system that facilitates children's ability to take narrative perspectives through the mechanism of reporting speech. The toy presented works by asking children to tell stories and by playing back the stories to the child using narrative features. The ability to express the way the characters think and feel in a narrative and what motivates them to act has been shown to be predictive of academic competence among preschool children. A user study was conducted to understand the short-term effect of Dolltalk on children's elaboration of internal states of story characters. The results show that playing with Dolltalk encourages children to introduce their characters in the story and to express the internal states of their characters much more than with the use of a simple tape recorder. The results also show that playing with the current version of Dolltalk or with Dolltalk in tape-recorder mode encourages children to provide spatial and temporal information in their stories much more than they would without hearing any playback of their stories. This thesis presents significant results (p =.04) that indicate the current version of Dolltalk encourages children to express the internal states of their characters.

Full textIncludes bibliographical references (leaves 87-92).
Every story about an event offers a unique perspective about the event. A popular sporting event, such as a Major League Baseball game, is followed by several summary articles that show different points of view. The goal of this research is to build a computational model of perspective and build a system for automatically generating multiple summary articles showing different perspectives. My approach is to take a neutral summary article, reorder the content of that summary based on event features extracted from the description of the game, and produce two new summaries showing the local team perspectives. I will present an initial user survey that validated the hypothesis that content ordering has a significant effect on the users' perception of perspective. I will also discuss collecting and analyzing a parallel corpus of baseball game data and summary articles showing local team perspectives. I will then describe the reordering algorithm, the implementation of the system, and a user study to evaluate the output of the system.

Full textFirst, the thesis explores a forward engineering approach by outlining the required perceptional components and implementing these components on a humanoid iCub robot. Prior to and during the perspective taking, the iCub learns the environment and recognizes its constituent objects before approximating the gaze of surrounding humans based on their head poses. Inspired by psychological studies, two separate mechanisms for the two types of perspective taking are employed, one based on line-of-sight tracing and another based on the mental rotation of the environment.
Acknowledging that human head pose is only a rough indication of a human's viewpoint, the thesis introduces a novel, automated approach for ground truth eye gaze annotation. This approach is used to collect a new dataset, which covers a wide range of camera-subject distances, head poses, and gazes. A novel gaze estimation method trained on this dataset outperforms previous methods in close distance scenarios, while going beyond previous methods and also allowing eye gaze estimation in large camera-subject distances that are commonly encountered in human-robot interactions.
Finally, the thesis proposes a computational model as an instantiation of a reverse engineering approach, with the aim of understanding the underlying mechanisms of perspective taking in humans. The model contains a set of forward models as building blocks, and an attentional component to reduce the model's response times. The model is crucial in explaining human data in congruency matching experiments and suggests that humans implement a similar attentional mechanism. Several testable predictions are put forward, including the prediction that forced early responses lead to an egocentric bias. Experimental results on the computational formalization of perspective taking also open up future possibilities of exploring links to other perceptional and cognitive mechanisms, such as active vision and autobiographical memories.

Full textAnnonsering på sociala medier, och speciellt på Facebook, är en global industri som de sociala medieplattformarna har som största intäktskälla. Hur lyckosamma dessa annonser är i förhållande till hur mycket pengar som investeras i dem kan mätas med nyckeltalet kostnad per tusen intryck (eng: Cost per thousand impressions, CPM). I den här uppsatsen är olika regressionsmodeller av statistisk inlärning byggda för prediktering av CPM med syftet att hitta den modell som bäst kan prediktera CPM. Genom att använda 540 företags annonsdata i Sverige under 2017 upptäcks det att de 12 förklaringsvariablerna kraftigt samvarierar varav olika shrinkage regressionsmodeller byggs. Genom att först använda Ridge och Lasso, vilka sen kombineras i ett elastiskt nät och slutligen genom att utvidga Lasso till elastisk Lasso, upptäcks det att den modell som presterar bäst utifrån cross-validation är det elastiska nätet där ungefärligen lika stora vikter läggs på Ridge och Lasso. Slutsatsen är att för att regressera ett nyckeltal som CPM, där det är sannolikt att förklaringsvariablerna samvarierar, är shrinkage regressionsmodeller att föredra.
Brearcliffe, Dale K. "Parallelization of Entity-Based Models in Computational Social Science| A Hardware Perspective." Thesis, George Mason University, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10684969.
Full textThe use of simulations by social scientists in exploring theories and hypotheses is well documented. As computer systems have grown in capacity, so have interests of social scientists in executing larger simulations. Social scientists often approach their simulation design from the top down by selecting an Entity-Based Model (EBM) framework from those that are readily available, thus limiting modeling capability to the available frameworks. Ultimately, the framework is dependent upon what is at the bottom, the hardware architecture that serves as the foundation of the computing system. Parallel hardware architecture supports the simultaneous execution of a problem split into multiple pieces. Thus, the problem is solved faster in parallel. In this thesis, a selection of parallel hardware architectures is examined with a goal of providing support for EBMs. The hardware's capability to support parallelization of EBMs is described and contrasted. A simple EBM is tested to illustrate these capabilities and implementation challenges specific to parallel hardware are explored. The results of this research offer social scientists better informed choices than the sequential EBM frameworks that currently exist. Matching the model to the correct supporting hardware will permit larger scale problems to be examined and expands the range of models that a social scientist can explore.

Labor market institutions are central for modern economies, and their polices can directly affect unemployment rates and economic growth. At the individual level, unemployment often has a detrimental impact on people's well-being and health. At the national level, high employment is one of the central goals of any economic policy, due to its close association with national prosperity. The main goal of this thesis is to highlight the need for frameworks that take into account the complex structure of labor market interactions. In particular, we explore the benefits of leveraging tools from computational social science, network science, and data-driven theories to measure the flow of opportunities and information in the context of the labor market. First, we investigate our key hypothesis, which is that opportunity/information flow through weak ties, and this is a key determinant of the length of unemployment. We then extend the idea of opportunity/information flow to clusters of other economic activities, where we expect the flow within clusters of related activities to be higher than within isolated activities. This captures the intuition that within related activities there are more "capitals" involved and that such activities require similar "capabilities." Therefore, more extensive clusters of economic activities should generate greater growth through exploiting the greater flow of opportunities and information. We quantify the opportunity/information flow using a complexity measure of two economic activities (i.e. jobs and exports).

Full textNeuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system. Much is known about neuromodulators, but their structural and functional implications in fundamental behavior remain unclear. This dissertation set out to investigate the interaction of neuromodulators and their role in modulating behaviors by combining methodologies in computational modeling, game theory, embodiment, pharmacological manipulations, and neuroinformatics. The first study introduces a novel computational model that predicts how dopamine and serotonin shape competitive and cooperative behavior in a game theoretic environment. The second study adopted the model from the first study to gauge how humans react to adaptive agents, as well as measuring the influence of embodied agents on game play. The third study investigates functional activity of these neuromodulatory circuits by exploring the expression energy of neuromodulatory receptors using the Allen Brain Atlas. The fourth study features a web application known as the Allen Brain Atlas-Drive Visualization, which provides users with a quick and intuitive way to survey large amounts of expression energy data across multiple brain regions of interest. Finally, the last study continues exploring the interaction of dopamine and serotonin by focusing specifically on the reward circuit using the Allen Brain Atlas. The first two studies provide a more behavioral understanding of how dopamine and serotonin interacts, what that interaction might look like in the brain, and how those interactions transpire in complex situations. The remaining three studies uses a neuroinformatics approach to reveal the underlying empirical structure and function behind the interactions of dopamine, serotonin, acetylcholine and norepinephrine in brain regions responsible for the behaviors discussed in the first two studies. When combined, each study provides an additional level of understanding about neuromodulators. This is of great importance because neuroscience simply cannot be explained through one methodology. It is going to take a multifaceted effort, like the one presented in this dissertation, to obtain a deeper understanding of the complexity behind neuromodulators and their structural and functional relationship with each other.

Full textEls animals van evolucionar per sobreviure en entorns dinàmics desenvolupant múltiples estratègies de comportament per adaptar-se i aprendre de la seva interacció amb el món. Els mecanismes associatius i les representacions internes estan en el nucli del càlcul del cervell, però, per adquirir un coneixement complet de la seva rellevància per a la conducta, cal tenir en compte la seva naturalesa incorporada. En un esforç interdisciplinari que integra mètodes de modelització computacional, robòtica i electrofisiologia, aquesta tesi presenta una sèrie d’estudis que pretenen avançar en la comprensió dels processos automàtics i deliberats que regulen el control de l’acció incorporat al cervell. Mitjançant la formulació d’una arquitectura de control biològicament restringida dedicada a una tasca de forjat en el món real, posem el terreny per modelar i analitzar una conducta orientada a objectius complexos que sorgeix de la interacció entre el sistema cerebrovascular cerebral automàtic que adquireix associacions sensorials motores i deliberat sistema fronto-hipocamp que proporciona una navegació i una planificació orientades a objectius. Després de l’anàlisi conductual del model d’estímul-resposta de l’aprenentatge cerebel.lari, ens preguntem més endavant com es pot aplicar el cerebel a un control anticipat que e ́s a la vegada adaptatiu i resistent a la incertesa. Per respondre a aquesta pregunta, explorem les propietats del sistema de control automàtic i avancem una nova hipòtesi sobre el paper del cerebel, tot reformant la seva computacio ́ en el domini perceptiu. Finalment, preguntem com interactuen els sistemes automa`tic i deliberat durant situacions inesperades que requereixen un canvi sobtat de plans. Analitzant la dina`mica neural de l’escorça frontal humana en el control del canvi d’acció deliberada, recolzem l’aportació de dinàmiques oscil.ladores de baixa freqüència en aquesta àrea per orquestrar el comportament, basant-se en representacions internes d’objectius i regles. Tot plegat, aquests resultats contribueixen a la nostra comprensió de com processos automàtics i deliberats controlen l’acció en el cervell i avancen noves idees que desafien o allarguen les teories actuals. Malgrat l’objectiu principal d’entendre el cervell, aquestes idees també es podrien aplicar al desenvolupament de nous sistemes de control per a una nova generació de robots.

Full textBayesian inference answers key questions of perception such as: "What should I believe given what I have perceived ?". As such, it is a rich source of models for cognitive science and neuroscience (Knill and Richards, 1996). This PhD manuscript explores two such models. We first investigate an efficient coding problem, asking the question of how to best represent probabilistic information in unrealiable neurons. We innovate compared to older such models by introducing limited input information in our own. We then explore a brand new ideal observer model of localization of sounds using the Interaural Time Difference cue, when current models are purely descriptive models of the electrophysiology. Finally, we explore the properties of the Expectation Propagation approximate-inference algorithm, which offers great potential for both practical machine-learning applications and neuronal population models, but is currently very poorly understood
Vignola, Emanuele. "A Theoretical Perspective on Hydrogenation and Oligomerization of Acetylene over Pd Based Catalysts." Thesis, Lyon, 2017. http://www.theses.fr/2017LYSEN054/document.
Full textSelective hydrogenation of acetylene in ethylene-rich flows is a fundamental process in the petrochemical industry since it allows the purification of ethylene for polymer applications. The reaction is catalyzed by Pd, which features acceptable selectivity towards ethylene compared to the total hydrogenation product, ethane. Pure Pd is, however, deactivated by oligomeric byproducts, known as ”green oil” in the literature. Therefore, most industrial catalysts are Pd-Ag alloys, where Ag helps to suppress the secondary reactions. This work addresses the formation of initial oligomers on Pd and Ag-Pd catalysts. A mean field based theoretical model was built to efficiently screen the topology of the topper most layer of the alloy catalyst under relevant conditions. This model gave evidence for strongly favored Pd island formation. To confirm this result, the system was then re-investigated by means of Monte Carlo simulations including the effect of segregation. Emergence of large domains of Pd were confirmed over large ratios of Ag to Pd. Green oil is expected to form on these catalytically active islands. To obtain a detailed view on the oligomerization process, activation energies were computed both for hydrogenation and oligomerization steps by periodic density functional theory on Pd(111). Oligomerization was found to be competitive with hydrogenation, with the hydrogenation of the oligomers being among the fastest processes. The role of Pd domains to green oil formation is still to be clarified under realistic conditions, where the surface is covered by many different species. A step forward to this goal was taken by developing a machine-learning tool which automatically interpolates model Hamiltonians on graphical lattices based on DFT computations, accounting for lateral interactions and distorted adsorption modes on crowded surfaces

This thesis describes the design and implementation of machine learning algorithms and real-time recommendations within EWall, a software system used for individual and collaborative information management. In the EWall workspace, users collect and arrange cards, which are compact visual abstractions of information. A significant problem that often arises when humans try to collect information is information overload. Information overload refers to the state of having too much information, and it causes difficulty in discovering relevant information. When affected by information overload, the user loses focus and spends more time filtering out irrelevant information. This thesis first presents a simple solution that uses a set of algorithms that prioritize information. Based on the information the user is working with, the algorithms search for relevant information in a database by analyzing spatial, temporal, and collaborative relationships. A second, more adaptive solution uses agents that observe user behavior and learn to apply the prioritization algorithms more effectively. Adaptive agents help to prevent information overload by removing the burden of search and filter from the user, and they hasten the process of discovering interesting and relevant information.

This paper situates it self in the line of research Program of Graduate Studies in Education: Curriculum of the Pontifical Catholic University of São Paulo. It aims to reflect on the approximations between the concept of computational thinking and education in a liberating perspective. In order to do so, it leads to qualitative exploratory research on the subject by the survey of academic production of theses and dissertations produced at the Pontifical Catholic University of São Paulo (PUC-SP) and at State University of Campinas (UNICAMP), seeking the concept in titles, abstracts and keywords of 58,871 works carried out from 1965 to 2016. From this survey and analysis, the concept of “Computational Thinking for Education” is coined in a liberating perspective, based on the reflections on technology discussed in the works of Vieira Pinto and Milton Santos, of the concepts on Computational Thinking with the contributions of authors like Papert and Valente and liberating education, in the perspective given by Freire and Shor. This research concludes that computational thinking is an embryonic concept in the researched universities appearing in only one academic work and that it is not only possible to transpose computational thinking to basic education, but it is also possible to do so in a liberating way

A partir deste levantamento e análise, é encetada a tessitura do conceito de “Pensamento computacional educacional”, numa perspectiva libertadora, a partir das reflexões sobre tecnologia debatidas nas obras de Vieira Pinto e Milton Santos, dos conceitos sobre Pensamento Computacional com as contribuições de autores como Papert e Valente, e educação libertadora, na perspectiva dada por Freire e Shor. Esta pesquisa conclui que o pensamento computacional é um conceito embrionário nas universidades pesquisadas, aparecendo em apenas um trabalho acadêmico e que não só é possível fazer a transposição do pensamento computacional para o ensino básico, como também é possível fazê-lo de forma libertadora

The study examines programming processes from the point of view of semiotics. Based on key concepts of computation and programming, it presents a critical review of the book Semiotics of Programming by Kumiko Tanaka-Ishii. The starting point is the Peircean argument of the affinity between the structure of logical reasoning and the mechanical processes in the logical machines of Jevons, Marquand e Babbage. The author takes the view that the philosophy of machines developed by Peirce in this context can serve as the basis of a computational semiotics and anchor a semiotics of programming appropriate to overcome prevailing dualist and Cartesian approaches, according to which human reasoning differs essentially from processes in nature in general and from mechanical processes in particular. The study reveals gaps in the semiotic theory of computation by Tanaka-Ishii, proposes ways to overcome them through the application of Peirce s semiotics and argues that the Peircean approach promises a better understanding of the cognitive processes involved in computation and programming
O estudo examina os processos de programação do ponto de vista da semiótica. Com base em conceitos chave da computação e programação, apresenta numa análise crítica do livro Semiotics of Programming de Kumiko Tanaka-Ishii. O ponto de partida é o argumento peirceano da afinidade entre as estruturas do raciocínio lógico e dos processos mecânicos nas máquinas lógicas de Jevons, Marquand e Babbage. O autor defende a tese de que a filosofia das máquinas desenvolvida por Peirce nesse contexto pode servir como base de uma semiótica computacional e ancorar uma semiótica da programação apropriada para ultrapassar abordagens preponderantes dualistas e cartesianas, conforme as quais o raciocínio humano difere essencialmente de processos na natureza em geral e de processos mecânicos em particular. O estudo revela lacunas na teoria semiótica computacional de Tanaka-Ishii, propõe caminhos para preenchê-las através da aplicação da semiótica de Peirce e postula que a abordagem peirceana promete uma melhor compreensão dos processos cognitivos envolvidos na computação e na programação

Full textAbstrakti Tässä työssä tutkittiin lingvistisen tiedon hyödyllisyyttä kieliteknologian yhdellä sovellusalueella eli sanan ennakointia englannin kielessä. Sovellus pyrkii ennakoimaan sanan, jota käyttäjä kirjoittaa parhaillaan tai aikoo kirjoittaa seuraavaksi. Nämä sovellukset ovat hyödyllisiä esim. pienissä päätelaitteissa, joissa tekstin tuottaminen on hankalaa. Eräs kieliteknologiasovellusten tärkeimmistä ominaisuuksista on niiden tehokas toiminta ja suorituskyky, jonka tulisi olla kvantitatiivisesti mitattavissa. Oleellisin tutkimuskysymys on näin ollen: (1) miten käytännön kieliteknologiasovellusten suorituskykyä voidaan parantaa merkittävästi lingvistisen tiedon avulla ja (2) mitä tämä vaatii käytännössä? Yleisellä tasolla tutkimuksen tärkeimmät tulokset ovat seuraavat: lingvistisen tiedon käytännön hyödyllisyyttä pitäisi arvioida ainakin kolmesta näkökulmasta, jotka ovat: (1) kielen näkökulma, (2) teknologian näkökulma ja (3) sovelluksen käyttäjän näkökulma. Näiden kolmen näkökulman avulla voidaan määrittää joukko tekijöitä, jotka joko lisäävät tai vähentävät lingvistisen tiedon hyödyllisyyttä käytännön kieliteknologiasovelluksissa. Työn empiirisessä osassa kehitettiin tilastollinen sananennakointisovellus englannin kieleen hyödyntäen parhaiten toimivia ennakointitekniikoita yhdessä ja samassa järjestelmässä. Kehitetyssä järjestelmässä suorituskyky vastaa täysin aiempien järjestelmien suorituskykyä. Työssä testattiin myös joitakin uusia, lingvististä tietoa hyödyntäviä ennakointitekniikoita, joiden suorituskyky vastasi tiettyjen tilastollisten ennakointimenetelmien suorituskykyä. Tutkimuksen tuloksista voidaan päätellä muun muassa, että sananennakointisovellusten suorituskykyä voidaan parantaa merkittävästi lingvistisen tiedon avulla vain käyttämällä samanaikaisesti useita lingvistisen tiedon lähteitä. Tämä taas saattaa hidastaa sovelluksen reaaliaikaista toimintaa ja vaikuttaa sovelluksen suorituskykyyn silloin kun se mitataan näppäinsäästönä merkkisäästön asemesta

Full textOn a web-based computerized environment collective authorship was interdisciplinarily researched on teachers who were studying (graduate or extension) English as a foreign language. This study was linked to research lines “Digital Interfaces in Education, Art, Language and Cognition” of Post Graduate Programme in Computer Science in Education of the Federal University of Rio Grande do Sul, and to dialogical interaction and technologies group of studies at the Language, Interaction and Cognition Studies Laboratory, LELIC, based on Mikhail Bakhtin’s philosophy of language. EquiText, a tool for collaborative writing on the web and/or a virtual learning environment developed in this University, provided three experiments: two at the Institution of Higher Education 1, IES 1, with voluntary students from a Languages course – focus on the English language teaching; and a third one at IES 2 with English teachers. Besides the general objective to examine authorship using EquiText, specific objectives analysed dialogical relationships established by research participants: i) with EquiText, i.e., procedural-symbolic manifestations; ii) between themselves (with the other); and, iii) with the text, in textual construction independent from English language proficiency. The theoretical presuppositions were these key-concepts: statement, dialogical relationships, and text, as in Bakhtin (2000); and presentiality, as in Axt (2006). Texts were analysed in three dialogic action plans: procedural, interactional and textual. Results point out to possibilities of the establishment of a collective authorship space-time production due to a satisfying conjunction of at least two conditions: a collaborative writing technological spacetime (the EquiText); and a pedagogic space-time, reinforced by dialogic interaction principles, simultaneously refreshable by participants in relation to the collaborative text under construction, in three manifestation plans. They are: procedural, or the relations between the “I” and the technology; interactional, or the encounter of the “I” and the other; and textual, the “I” and the written text under collective production. The thesis plan comprises five chapters: the presentation (1); the English language, written, supported by technologies (2); the presentation of main author, key concepts used, and a construct to analyses (3); the methodology, procedures, and analyses (4); and, final considerations (5).

Full textO desenvolvimento da Ãrea de InteligÃncia Artificial (IA) trouxe grandes avanÃos para a resoluÃÃo de problemas computacionalmente difÃceis. No entanto, a meta inicial da IA, de implementaÃÃo de uma inteligÃncia genuÃna de forma artificial, ainda nÃo foi alcanÃada. Por isso, a grande maioria dos pesquisadores da Ãrea mudou o foco de suas pesquisas para resoluÃÃo de problemas, em geral abandonando a meta de uma inteligÃncia artificial. Para continuar perseguindo essa meta, outros pesquisadores passaram a questionar os princÃpios filosÃficos da IA e tomar novos rumos. Alguns deles perceberam que o processo da inteligÃncia nÃo à puramente mental. De acordo com essa nova visÃo, o corpo tem um papel fundamental no processo cognitivo. A partir desse ponto de vista, visando superar obstÃculos tradicionais da IA, surgiu a IA Corporificada. Esta tem uma forte tendÃncia a implementaÃÃo em robÃs, para se desenvolver um melhor projeto sobre o corpo. PorÃm, apesar de ter obtido avanÃos em relaÃÃo a problema da IA tradicional, a IA Corporificada comeÃou a apresentar suas prÃprias limitaÃÃes. Surgiu entÃo a ideia de que um agente genuinamente inteligente deve formular seus prÃprios problemas a partir da percepÃÃo da realidade, construÃda em termo do seus aparato sensÃrio-motor. Em outras palavras, a inteligÃncia genuÃna està ligada à autonomia do agente. A IA Enativa surgiu influenciada por estudos biolÃgicos a respeito da autonomia. Nessa Ãrea da IA a meta à construir um agente artificial autÃnomo. Este trabalho relata a trajetÃria da IA desde a sua fundaÃÃo, passando pela vertente da IA Corporificada, e apontando um possÃvel novo paradigma da IA Enativa. AlÃm disso, nÃs Analisamos e discutimos os processos que levaram pesquisadores a questionar o embasamento filosÃfico da IA e a formular novos conceitos a respeito do que à inteligÃncia.
The development in the Artificial Intelligence (AI) field brought great improvement to the resolution of computationally hard problems. However, the early goal of AI, of implementing a genuine intelligence in an artificial way, was not achieved. Therefore most of the fieldâs researchers changed their researchâs focus to problem resolution, quitting the goal of an artificial intelligence. To keep pursuing that goal others researchers started questioning the philosophical principles of AI and they took new routes. Some of them realized that the process of intelligence is not purely mental. According to this new view the body has a fundamental role in the cognitive process. From this point of view, aiming to overcome traditional obstacles of AI, the Embodied AI emerged. It has a strong tendency to implementation in robots, to develop a better design of the body. Despite having achieved improvements over the problem of traditional AI, Embodied AI started to present its own limitations. Then came the idea that a genuinely intelligent agent must formulate its own problems from the perception of reality, constructed in terms of their sensory-motor apparatus. In other words, the genuine intelligence is linked to the agentâs autonomy. The Enactive AI appeared influenced by biological studies about autonomy. In this AI field the goal is to build an autonomous artificial agent. This paper reports the trajectory of AI since its foundation, through strand of Embodied AI, and pointing to a possible new paradigm of Enactive AI. In addition, we analyse and discuss the processes that led researchers to question the philosophical basis of IA and formulate new concepts about what intelligence is.
