Abstract (sommario):
The efficient coding hypothesis states that neural response should maximize its information about the external input. Theoretical studies focus on optimal response in single neuron and population code in networks with weak pairwise interactions. However, more biological settings with asymmetric connectivity and the encoding for dynamical stimuli have not been well-characterized. Here, we study the collective response in a kinetic Ising model that encodes the dynamic input. We apply gradient-based method and mean-field approximation to reconstruct networks given the neural code that encodes dynamic input patterns. We measure network asymmetry, decoding performance, and entropy production from networks that generate optimal population code. We analyze how stimulus correlation, time scale, and reliability of the network affect optimal encoding networks. Specifically, we find network dynamics altered by statistics of the dynamic input, identify stimulus encoding strategies, and show optimal effective temperature in the asymmetric networks. We further discuss how this approach connects to the Bayesian framework and continuous recurrent neural networks. Together, these results bridge concepts of nonequilibrium physics with the analyses of dynamics and coding in networks.

Abstract (sommario):
Neurons in the auditory brain stem encode signals with exceptional temporal precision. A low-threshold potassium current, IKLT, present in many auditory brain stem structures and thought to enhance temporal encoding, facilitates spike selection of rapid input current transients through an associated dynamic gate. Whether the dynamic nature of IKLT interacts with the timescales in spectrally rich input to influence spike encoding remains unclear. We examine the general influence of IKLT on spike encoding of stochastic stimuli using a pattern classification analysis between spike responses from a ventral cochlear nucleus (VCN) model containing IKLT, and the same model with the IKLT dynamics removed. The influence of IKLT on spike encoding depended on the spectral content of the current stimulus such that maximal IKLT influence occurred for stimuli with power concentrated at frequencies low enough (<500 Hz) to allow IKLT activation. Further, broadband stimuli significantly decreased the influence of IKLT on spike encoding, suggesting that broadband stimuli are not well suited for investigating the influence of some dynamic membrane nonlinearities. Finally, pattern classification on spike responses was performed for physiologically realistic conductance stimuli created from various sounds filtered through an auditory nerve (AN) model. Regardless of the sound, the synaptic input arriving at VCN had similar low-pass power spectra, which led to a large influence of IKLT on spike encoding, suggesting that the subthreshold dynamics of IKLT plays a significant role in shaping the response of real auditory brain stem neurons.

Abstract (sommario):
Non-Constant Luminance (NCL) and Constant Luminance (CL) are the two common methods for converting RGB values to luma and chroma for compression efficiency. CL coefficients have been derived from the luminous efficacy of the used gamut color primaries in the light linear domain. NCL applies the same coefficients but on non-linear inputs, which are perceptually encoded values using proper transfer function, thus leading to reduced compression efficiency and color shifts. However, since legacy cameras capture perceptually encoded values of light, it is common practice to use NCL in the existing video distribution pipelines. Although color distortion was not a serious problem with legacy Standard Dynamic Range (SDR) systems, this is not the case with High Dynamic Range (HDR) applications where color shifts become much more visible and prohibitive to delivering high quality HDR. In this thesis, we propose methods that address the inefficiencies of the conventional NCL method by optimizing NCL luma values to be as close as possible to those of CL, thus improving compression performance and color accuracy, while maintaining the current pipeline infrastructure. First, we develop a global optimization method for deriving new optimum coefficients that approximate NCL values to those of the CL approach. Then, we improve upon this approach by conducting content based optimization. This adaptive optimization method takes content pixel density into consideration and optimizes only based on these color distributions. Finally, we propose a weighted global optimization method, which separates chromaticity into three categories (Red, Green, and Blue), and assigns weights based on their contributions to luminance. Evaluations show that the proposed method improves color quality and compression efficiency over NCL.

Al, Zadjali Hanaa. "Compressing labels of dynamic XML data using Base-9 scheme and Fibonacci encoding". Thesis, University of Sheffield, 2017. http://etheses.whiterose.ac.uk/18571/.

Testo completo
Abstract (sommario):
The flexibility and self-describing nature of XML has made it the most common mark-up language used for data representation over the Web. XML data is naturally modelled as a tree, where the structural tree information can be encoded into labels via XML labelling scheme in order to permit answers to queries without the need to access original XML files. As the transmission of XML data over the Internet has become vibrant, it has also become necessary to have an XML labelling scheme that supports dynamic XML data. For a large-scale and frequently updated XML document, existing dynamic XML labelling schemes still suffer from high growth rates in terms of their label size, which can result in overflow problems and/or ambiguous data/query retrievals. This thesis considers the compression of XML labels. A novel XML labelling scheme, named “Base-9”, has been developed to generate labels that are as compact as possible and yet provide efficient support for queries to both static and dynamic XML data. A Fibonacci prefix-encoding method has been used for the first time to store Base-9’s XML labels in a compressed format, with the intention of minimising the storage space without degrading XML querying performance. The thesis also investigates the compression of XML labels using various existing prefix-encoding methods. This investigation has resulted in the proposal of a novel prefix-encoding method named “Elias-Fibonacci of order 3”, which has achieved the fastest encoding time of all prefix-encoding methods studied in this thesis, whereas Fibonacci encoding was found to require the minimum storage. Unlike current XML labelling schemes, the new Base-9 labelling scheme ensures the generation of short labels even after large, frequent, skewed insertions. The advantages of such short labels as those generated by the combination of applying the Base-9 scheme and the use of Fibonacci encoding in terms of storing, updating, retrieving and querying XML data are supported by the experimental results reported herein.

Abstract (sommario):
Bats are known for their highly capable biosonar systems which make them be able to navigate and forage in dense vegetation. Their biosonar system consists of one emitter (nose or mouth) and two receivers (ears). Some bat species, e.g. in the rhinolophid and hipposiderid families, have complicated pinna motion patterns. It has been shown that these pinna motion patterns fall into two distinct categories: rigid motions and non-rigid motions. In the current work, the pinna of Pratt's leaf-nosed bat (Hipposideros pratti) was used as a biological model system to understand how a sensor could benefit from variability. Hence, the variability in the rigid pinna motions and in the non-rigid pinna motions has been investigated by tracking a dense set of landmarks on the pinna surface with stereo vision. Axis-angle representations have shown that the rigid pinna motions exhibited a large continuous variation with rotation axes covering 180 degrees in azimuth and elevation. Distributions of clusters of the landmarks on the pinna surface have shown that the non-rigid pinna motions fall into at least two subgroups. Besides, the acoustic impact of the rigid pinna motions have been investigated using a biomimetic pinna. Normalized mutual information between the acoustic inputs with different rotation axes has shown that different rotation axes can provide at least 50% new sensory information. These results demonstrate that the variability in the pinna motions is an interesting concept for sensor, and how the bats approach that needs to be further investigated.
Master of Science
Sensors have been developed for a long time, and they can be used to detect the environments and then deliver the required sensing information. There are many different types of sensors, such as vision-based sensors (infrared camera and laser scanner) and sound-based sensors (sonar and radar). Ultrasonic transducers are one of the sound-based sensors, and they are more stable and reliable in environments where smoke or steam is present. Similar to human-made ultrasonic transducers, bats have developed highly capable biosonar systems that consist of one ultrasonic emitter (nose or mouth) and two ultrasonic receivers (ears), and these biosonar systems enable them to fly and hunt in cluttered environments. Some bats, e.g. rhinolophid and hipposiderid bats, have dynamic noseleaves (elaborate baffle shapes surrounding the nostrils) and pinna (outer ear), and these could enhance the sensing abilities of bats. Hence, the purpose of this thesis has been to investigate this variability to improve the human-made sensors by focusing on the dynamic pinna of the bats. It has been shown that bats have two distinct categories of pinna motions: rigid motions which change only the orientation of the pinna, and non-rigid motions which change also the shape of the pinna. However, the variability within the rigid and non-rigid pinna motions has received little attention. Therefore, the present work has investigated the variability in the rigid pinna motions and in the non-rigid pinna motions. Landmark points were placed on the pinna of certain bats and the pinna motions were tracked by high-speed video cameras. The rigid pinna motions exhibit a large continuous variation in where the pinna is orientated during rotation. Distributions of clusters of the landmarks on the pinna have shown that the non-rigid pinna motions fall into at least two subgroups. The acoustic impacts of the rigid pinna motions have been studied by a biomimetic pinna which reproduced the observed range of the rigid pinna motions. Ultrasonic signals mimicking the bats were emitted to be received by the biomimetic pinna. Based on these signals, it has been shown that different rotation axes and even small changes can provide over 50% new sensory information. These findings give engineers a potential way to improve the human-made sensors.

Abstract (sommario):
With the rapid growth of XML documents to serve as a popular and major media for storage and interchange of the data on the Web, there is an increasing interest in using existing traditional relational database techniques to store and/or query XML data. Since XQuery is becoming a standard XML query language, significant effort has been made in developing an efficient and comprehensive XQuery-to-SQL query processor. In this thesis, we design and implement an XQuery-to-SQL Query Processor based on the Dynamic Intervals approach. We also provide a comprehensive translation for XQuery basic operations and FLWR expressions. The query processor is able to translate a complex XQuery query, which might include arbitrarily composed and nested FLWR expressions, basic functions, and element constructors, into a single SQL query for RDBMS and a physical plan for the XQuery-enhanced Relational Engine. In order to produce efficient and concise SQL queries, succinct XQuery to SQL translation templates and the optimization algorithms for the SQL query generation are proposed and implemented. The preferable merge-join approach is also proposed to avoid the inefficient nested-loop evaluation for FLWR expressions. Merge-join patterns and query rewriting rules are designed to identify XQuery fragments that can utilize the efficient merge-join evaluation. Proofs of correctness of the approach are provided in the thesis. Experimental results justify the correctness of our work.

Abstract (sommario):
Diese Doktorarbeit besteht aus zwei Teilen. In dem ersten Teil der Doktorarbeit behandele ich die Kodierung von Kommunikationssignalen in einem burstenden Interneuron im auditorischen System des Grashuepfers Chorthippus biguttulus. Mit der Anzahl der Aktionspotentialen im Burst wird eine zeitliche Komponente der Kommunikationssignale - die Pausendauer - wiedergegeben. Ein Modell basierend auf schneller Exzitation und langsamer Inhibition kann diese spezielle Kodierung erklaeren. Ich zeige, dass eine zeitliche Integration der Aktionspotentiale dieses burstenden Interneurons dazu genutzt werden kann, die Signale zeitskaleninvariant zu dekodieren. Dieser Mechanismus kann in ein umfassenderes Modell eingebaut werden, dass die Verhaltensantwort des Grashuepfers auf Kommunikationssignale widerspiegelt. Im zweiten Teil der Doktorarbeit benutze ich Konzepte aus der Informationstheorie und der Theorie linearer dynamisches Systeme, um den Begriff der ''vorhersagenden Information'' zu operationalisieren. Im einfachen Fall der informations-theoretisch optimalen Vorhersage des naechsten Zeitschrittes, erhalte ich Eigenvektoren, die denjenigen eines anderen etablierten Algorithmuses, der sogenannten ''Slow Feature Analysis'', entsprechen. Im allgemeinen Fall optimiere ich die vorhersagenden Information, die die Vergangenheit des Inputs eines dynamischen Systems ueber die Zukunft des Outputs enthaelt. Dabei gelange ich zu einer informations-theoretisch optimalen Charakterisierung eines reduzierten Systems, die auf den Eigenvektoren der konditionalen Kovarianzmatrix zwischen Inputvergangenheit und Outputzukunft basiert.
This thesis consists of two parts. In the first part, I investigate the coding of communication signal in a bursting interneuron in the auditory system of the grasshopper Chorthippus biguttulus. The intra-burst spike count codes one temporal feature of the communication signal - pause duration. I show that this code can be understood by a model of parallel fast excitation and slow inhibition. Furthermore, temporal integration of the spike train of this bursting interneuron results in a desirable time-scale invariant read-out of the communication signal. This mechanism can be integrated into a more comprehensive model that can explain behavioural response of grasshoppers. In the second part of this thesis, I combine concepts from information theory and linear system theory to operationalize the notion of ''predictive information''. In the simple case of predicting the next time-step of a signal in an information-theoretic optimal sense, I obtain a description by eigenvectors that are identical to another established algorith, the so-called ''Slow Feature Analysis''. In the general case I optimize a dynamical system such that the predictive information in the input past about the output future is optimalle compressed into the state space. Thereby, I obtain an information-theoretically optimal characterization of reduced system, based on the eigenvectors of the conditional covariance matrix between input past and output future.

Abstract (sommario):
Every animal on our planet wanders around when looking for something. Whether it is in search of food, a mate, or home, navigation is one of the most performed cognitive behaviors in Nature. Nevertheless, our understanding of how the brain is capable of solving such a simple problem − to move from one point to another − is still incomplete. The decomposition of navigation into cognitive components reveals the complexity of such behavior. To reach a goal, one has to first understand its current position, then to estimate the target position, followed by identifying a route towards the goal-location and, finally, to physically orchestrate a set of motor-actions leading to the desired location. Extensive research on the mammalian hippocampus has revealed its critical role in spatial navigation, memory, and learning. However, the mechanisms for spatial memory encoding, episodic representation, and their behavioral counterparts are still not fully understood. Moreover, we do not know if the mechanisms involved in spatial re- presentation also scale up to conceptual representation from a purely spatial domain, such as task cognitive demands. In this thesis, we present a set of studies focused on spatial and cognitive representation in the insect and mammalian organisms. We show that the problem of spatial representation requires multi-level solutions working simultaneously: from biophysical neuronal mechanisms to behavioral aspects of navigation. Furthermore, with physiological studies of the human medial temporal lobe, we propose that the mechanisms involved in spatial representation also extend to higher-order cognitive representations, therefore suggesting that the hippocampus handles information that is dimension independent.
Tots els animals del nostre planeta passegen mentre busquen alguna cosa. Ja sigui per trobar menjar, parella o un lloc per viure, la nave- gacio` `es un dels comportaments cognitius més realitzats en la natura. No obstant, la nostra comprensió de com el cervell és capaç de resoldre aquest senzill problema − moure’s d’un punt a un altre − encara és incompleta. La descomposició de la navegació en diferents components cognitius revela la complexitat d’aquest comportament. Per assolir un objectiu, hom ha de primer conèixer la seva posició, llavors estimar la posició destí, seguidament identificar una ruta o camí fins a aquesta i, finalment, orquestrar un conjunt d’accions motores que portin fins a la posició desitjada. L’àmplia recerca de l’hipocamp en mamífers ha revelat el seu paper fonamental en la navegació espacial, la memòria i l’aprenentatge. Tot i això, els mecanismes de codificació de la memòria espacial, la representació episódica i els seus homólegs encara no s’han pogut entendre completament. Tanmateix, encara no sabem si els mecanismes involucrats en la representació espacial també escalen des d’un domini purament espacial a la representació de conceptes, com ara les necessitats cognitives d’una tasca. En aquesta tesi presentem un conjunt d’estudis centrats en la representació espacial i cognitiva en el cervell d’insectes i mamífers. Mostrem que el problema de la representació espacial requereix de solucions amb múltiples nivells treballant simultàniament: des dels mecanismes neuronals biofísics fins als aspectes conductuals de la navegació. Per últim, a partir d’estudis fisiológics del lobul temporal mitjà de l’ésser humà, proposem que els mecanismes involucrats en la representació espacial també s’extenen a representacions cognitives d’alt nivell, suggerint que l’hipocamp s’encarrega de la informació independentment de la seva dimensió.

Abstract (sommario):
The authors review how attention helps track and process dynamic events, selecting and integrating information across time and space to produce a continuing identity for a moving, changing target. Rather than a fixed ‘spotlight’ that helps identify a static target, attention needs a mobile window or ‘pointer’ to track a moving target, picking up pieces of evidence along the way to determine not just what the target is, but what it is doing. Behavioural studies show that this dynamic version of attention is model-based, using familiar trajectories to help identify a target and to guide encoding of continuing input from its path. Attention has very coarse temporal resolution for both static and moving targets. However, when the focus of selection is on the move, a given location on a moving target’s path can be selected for extremely brief instants, as little as 50 ms, compared to the typical ‘dwell time’ or minimum duration of attention selection at a fixed location, of 200 ms or more. To determine the path of a moving object, attention must accurately process and sort the onsets and offsets in order to match an offset to the subsequent onset. This aspect of dynamic attention has been called the ‘when’ pathway and patient studies show that it is a qualitatively different system from spatial attention, being completely based in the right parietal lobe for events in both hemifields. Finally, like the salience map of spatial attention, temporal attention may have its own map that guides allocation to upcoming, current, and recent moments to select information at the appropriate time, changing the experience of time as it does so.

Abstract (sommario):
Force dynamics is an approach to knowledge representation that aims to describe how notions of force, resistance, and tendency enter into the representation of certain kinds of words and concepts. As a theory of causation, it specifies how the concept of cause may be grounded in people’s representations of force and spatial relations. This chapter reviews theories of force dynamics that have recently emerged in the linguistic, psychological, and philosophical literatures. In discussing these theories, it reveals how a force dynamic account of causation is able to account for many of the key phenomena in causal cognition, including the representation of individual causal events, the encoding of causal relations in language, the encoding of causal chains, and causation by omission.

Abstract (sommario):
Observer perspectives are used as a departure point for developing a dual-faceted framework for thinking about personal memory: the Constructive Encoding approach, which emphasizes the multiple sources of information available to memory at encoding; and the Reconstructive Retrieval approach, which stresses how the context of retrieval can affect the content of memory. Observer perspective memories are defended from two related objections (the argument from perceptual impossibility and the argument from perceptual preservation) by drawing on the insights of this dual-faceted framework. This chapter shows that memory can be (re)constructive, dynamic, and flexible, but also accurate and faithful to the past.

Abstract (sommario):
Internal states of bodily arousal contribute to emotional feeling states and behaviors. This chapter details the influence of interoceptive processing on emotion and describes how deficits in interoceptive ability may underpin aberrant emotional processes characteristic of clinical conditions. The representation and control of bodily physiology (e.g. heart rate and blood pressure) and the encoding of emotional experience and behavior share neural substrates within forebrain regions coupled to ascending neuromodulatory systems. This functional architecture provides a basis for dynamic embodiment of emotion. This chapter will approach the relationship between interoception and emotion within the interoceptive predictive processing framework and describe how emotional states could be the product of interoceptive prediction error minimization.

Abstract (sommario):
The book sets out Fergus Craik’s view of human memory as a dynamic activity of mind and brain. In this account, remembering is understood as a system of active cognitive processes, similar to the processes underlying attending, perceiving, and thinking. The book therefore extends and elaborates the concept of “levels of processing” proposed by Craik and Lockhart (1972). Thus, encoding processes are essentially the mental activities involved in perceiving and understanding, and retrieval is described as the partial reactivation of these same processes. It is further suggested that “memory traces” are represented by a hierarchically organized system of analyzers, modified, sharpened, and differentiated by encounters with successive events. This account proposes that episodic and semantic memory should be thought of as levels in a continuum of specificity rather than as separate systems of memory. The book also covers Craik’s views on working memory and on changes in memory as a function of aging. In the latter case the losses are attributed largely to a difficulty with the self-initiation of appropriate encoding and retrieval operations, compensated by support from the external environment. There is a short chapter on the cognitive neuroscience of human memory, and a final chapter bringing the ideas together. The book covers the development of these ideas, illustrated substantially by experiments from Craik’s own laboratory, and also by empirical and theoretical contributions from other researchers. The final product is a broad account of current ideas and findings in contemporary memory research but viewed from Craik’s personal theoretical standpoint.

Abstract (sommario):
This article describes the neural engineering framework (NEF), a systematic approach to studying neural systems that has collected and extended a set of consistent methods that are highly general. The NEF draws heavily on past work in theoretical neuroscience, integrating work on neural coding, population representation, and neural dynamics to enable the construction of large-scale biologically plausible neural simulations. It is based on the principles that neural representations defined by a combination of nonlinear encoding and optimal linear decoding and that neural dynamics are characterized by considering neural representations as control theoretic state variables.

Abstract (sommario):
This paper describes a method of achieving the positive, negative, and cross-product encodings in a two-step process. The cross-product information is carried on the moire pattern produced by crossed gratings in the encoding process. The removal of the final encoding step simplifies the original procedure and increases the available dynamic range of the film for the two encodings. Experimental results are presented.

Abstract (sommario):
The Pix Dynamic QR Code URI can be extended to allow for offline QR Code generation. The proposed solution involves generating URIs that can be used as a vehicle to transmit information from the client to the server, allowing the payee to generate their own URIs. The document also goes into detail about URI properties, encoding, and cryptography. The proposed design balances tradeoffs between the amount of data that can be transmitted and cryptographic guarantees, and uses commonly available cryptographic primitives to reduce implementation costs.

Testo completo
Abstract (sommario):
The ability of flowering plants to prosper throughout evolution, and for many crop plants to set fruit, is strongly dependent on their ability to attract pollinators. To that end many plants synthesize a spectrum of volatile compounds in their flowers. Scent is a highly dynamic trait that is strongly influenced by the environment. However, with high temperature conditions becoming more common, the molecular interplay between this type of stress and scent biosynthesis need to be investigated. Using petunia as a model system, our project had three objectives: (1) Determine the expression patterns of genes encoding biosynthetic scent genes (BSGs) and of several genes previously identified as encoding transcription factors involved in scent regulation under normal and elevated temperature conditions. (2) Examine the function of petunia transcription factors and a heterologous transcription factor, PAPl, in regulating genes of the phenylpropanoid/benzenoid scent pathway. (3) Study the mechanism of transcriptional regulation by several petunia transcription factors and PAPl of scent genes under normal and elevated temperature conditions by examining the interactions between these transcription factors and the promoters of target genes. Our work accomplished the first two goals but was unable to complete the third goal because of lack of time and resources. Our general finding was that when plants grew at higher temperatures (28C day/22C night, vs. 22C/16C), their scent emission decreased in general, with the exception of a few volatiles such as vanillin. To understand why, we looked at gene transcription levels, and saw that generally there was a good correlation between levels of transcriptions of gene specifying enzymes for specific scent compounds and levels of emission of the corresponding scent compounds. Enzyme activity levels, however, showed little difference between plants growing at different temperature regimes. Plants expressing the heterologous gene PAPl showed general increase in scent emission in control temperature conditions but emission decreased at the higher temperature conditions, as seen for control plants. Finally, expression of several transcription factor genes decreased at high temperature, but expression of new transcription factor, EOB-V, increased, implicating it in the decrease of transcription of BSGs. The major conclusion of this work is that high temperature conditions negatively affect scent emission from plants, but that some genetic engineering approaches could ameliorate this problem.
