We present a method for learning visually-grounded word meanings, given as input a set of videos paired with natural-language sentences describing them. Our method uses a uniform feature representation for all words and word types rather than relying on handcrafted features specific to each word. We learn words in a weakly-supervised manner, with no need for annotated bounding boxes around objects of interest. We encode words as Hidden Markov models such that word models can be composed according to a sentence's semantic structure to efficiently recognize events in videos. We use a discriminative variant of Baum-Welch to learn the parameters for our word models, and demonstrate that our approach is able to learn words capturing appearance, spatial relations, and temporal dynamics.

Recent progress of deep neural networks in computer vision and machine learning has enabled transformative applications across robotics, healthcare, and security. However, despite the superior performance of the deep neural networks, it remains challenging to understand their inner workings and explain their output predictions. This thesis investigates several novel approaches for opening up the "black box" of neural networks used in visual recognition tasks and understanding their inner working mechanism. I first show that objects and other meaningful concepts emerge as a consequence of recognizing scenes. A network dissection approach is further introduced to automatically identify the internal units as the emergent concept detectors and quantify their interpretability. Then I describe an approach that can efficiently explain the output prediction for any given image. It sheds light on the decision-making process of the networks and why the predictions succeed or fail. Finally, I show some ongoing efforts toward learning efficient and interpretable deep representations for video event understanding and some future directions.

Pełny tekst źródłaQuesta tesi affronta sperimentalmente gli effetti delle rappresentazioni visive sulle decisioni finanziarie. Ipotizziamo che le rappresentazioni visive dell'informazione finanziaria possano influenzare le decisioni. Per testare tali ipotesi, abbiamo condotto esperimenti online e mostrato che la scelta della rappresentazione visiva conduce a cambiamenti nell'attenzione, comprensione, e valutazione dell'informazione. Il secondo studio riguarda l'abilità dei consulenti finanziari di offrire giudizio esperto per aiutare consumatori inesperti nelle decisioni finanziarie. Abbiamo trovato che il contenuto della pubblicità influenza significativamente tanto l'esperto quanto l'inesperto, il che offre una nuova prospettiva sulle decisioni dei consulenti finanziari. Il terzo tema riguarda l'apprendimento da informazioni multidimensionali, l'adattamento al cambiamento e lo sviluppo di nuove strategie. Abbiamo investigato gli effetti dell'importanza delle "cues" e di cambiamenti dell'ambiente decisionale sull'apprendimento. Trasformazioni improvvise nell'ambiente decisionale sono più dannose di trasformazioni graduali.

Pełny tekst źródłaModular decompositions of protein interaction networks can be used to identify modules of cooperating proteins. The biological plausibility off these modules might be questioned though. This report describes how a modular decomposition can be completed with semantic information in the visual representation. Possible methods for creating modules of functionally related proteins are also proposed in this work. The results show that such modules, with advantage can be combined with modules from a graph decomposition, to find proteins that are likely to cooperate to perform certain functions in organisms

The design process is based on a recursive and iterative feedback between a designer's ideas and their physical representation. In most practices, this feedback takes place upon one single medium, which endows the designer with one single view on his ideas. However, having several views can contribute for a deeper and more informed critique of the physical representation of those ideas; ultimately it can lead to a better final product. In the first part of this study, the use of audio-visual interfaces as tools for representing the design process is proposed. The idea is to understand, through simulation, what beneficial effects a process based on multiple feedbacks can potentially have on the actual design. As such, five frameworks mapping graphics to sound were designed and implemented computationally. Although the referred interfaces were in fact designed as a means to support a claim, they mainly stand out as independent objects that carry a significance of their own. The second part of this research explores the relevance of these objects as media that yield new forms of audio-visual design, engage the user in design thinking, and support design education.

Pełny tekst źródłaThe quantity of images that populate the Internet is dramatically increasing. It becomes of critical importance to develop the technology for a precise and automatic understanding of visual contents. As image recognition systems are becoming more and more relevant, researchers in artificial intelligence now seek for the next generation vision systems that can perform high-level scene understanding. In this thesis, we are interested in Visual Question Answering (VQA), which consists in building models that answer any natural language question about any image. Because of its nature and complexity, VQA is often considered as a proxy for visual reasoning. Classically, VQA architectures are designed as trainable systems that are provided with images, questions about them and their answers. To tackle this problem, typical approaches involve modern Deep Learning (DL) techniques. In the first part, we focus on developping multi-modal fusion strategies to model the interactions between image and question representations. More specifically, we explore bilinear fusion models and exploit concepts from tensor analysis to provide tractable and expressive factorizations of parameters. These fusion mechanisms are studied under the widely used visual attention framework: the answer to the question is provided by focusing only on the relevant image regions. In the last part, we move away from the attention mechanism and build a more advanced scene understanding architecture where we consider objects and their spatial and semantic relations. All models are thoroughly experimentally evaluated on standard datasets and the results are competitive with the literature

Pełny tekst źródłaThis thesis proposes an approach for analyzing unpaired visual data annotated with time stamps by generating how images would have looked like if they were from different times. To isolate and transfer time dependent appearance variations, we introduce a new trainable bilinear factor separation module. We analyze its relation to classical factored representations and concatenation-based auto-encoders. We demonstrate this new module has clear advantages compared to standard concatenation when used in a bottleneck encoder-decoder convolutional neural network architecture. We also show that it can be inserted in a recent adversarial image translation architecture, enabling the image transformation to multiple different target time periods using a single network

Pełny tekst źródłaInspirados en la filosofía moral de Paul Ricoeur, para quien la ética general puede contribuir para cuestionar las convicciones donde se basa la ética aplicada, este estudio pretende identificar y cuestionar los principios éticos fundamentales que han fundado nuestra comprensión de lo que debe ser una buena fotografía de prensa desde mediados del siglo XIX. Es nuestra convicción que la reciente controversia sobre el World Press Photo, motivada por la dificultad en establecer un criterio claro y consensual que permita distinguir lo que es un procedimiento de postproducción legítimo e ilegítimo, demuestra que el viejo paradigma de la fotografía analógica dejó de estar capacitado para promocionar la confianza en el fotoperiodismo. A través de un análisis histórico y sistemático mostramos que fundamentar la credibilidad de la fotografía de prensa en su objetividad, realismo y naturaleza no artística no tiene ni justificación teórica ni utilidad práctica.
Building on the moral philosophy of Paul Ricoeur, for whom general ethics may play an important role in questioning the longstanding assumptions upon which the applied ethics are grounded, this study aims to identify and challenge the fundamental moral principles that have grounded our understanding of what a good press photograph is since the mid nineteenth-century. It is our contention that the recent controversy surrounding the World Press Photo, motivated by the difficulty for establishing a clear and consensual criterion to distinguish between legitimate and illegitimate post-processing procedures, demonstrates that the old paradigm of the analogue photography is no longer capable of promoting trust and confidence in photojournalism. Through an historical and a systematic analysis, we contend that basing press photography credibility on its objective, realistic and non-artistic nature is neither theoretically justified nor practically useful.

Visual processing in biological systems is classically described as a hierarchy of increasingly sophisticated representations, originating in primary visual cortex (V1), progressing through intermediate area V4, and ascending to inferotemporal cortex. The computational mechanisms that produce representations in intermediate area V4 have remained a mystery. In this thesis I show that the standard model, a quantitative model which extends the classical description of visual processing, provides a computational mechanism capable of reproducing and predicting the responses of neurons in area V4 with a translation invariant combination of V1 responses. Using techniques I have developed, model neurons accurately predict the responses of 8 V4 neurons to within-class stimuli, such as closed contours and gratings, and achieve an average correlation coefficient of 0.77 between predicted responses and measured V4 responses. Furthermore, model neurons fit to a V4 neuron's grating stimulus response, can qualitatively predict the V4 neuron's 2-spot reverse correlation map. These results successfully demonstrate the first attempt to bridge V1 and V4 experimental data, by describing how representation in V4 could emerge from the nonlinear combination of V1 neural responses.

Interpreting the results of visual object perception experiments is too often ill-posed due to the disparate and sparse choice of stimuli. To address this problem, we have developed a flexible new technique called Random Image Structure Evolution (RISE). In the simplest case, RISE involves the presentation of image sequences depicting the evolution of a coherent image from a seemingly random field, along with the reverse sequences depicting the transformation back into randomness. As it samples a subset of the space of possible stimulus images, RISE image processing strictly preserves low-level attributes such as frequency spectra and luminance, and RISE experiments are designed to provide objectively verifiable measures of the onset and offset of subjects' conscious percepts. In turn, these onset and offset measures can serve as quantitative markers for characterizing a number of intriguing perceptual phenomena. Here I describe the basic RISE paradigm and discuss experimental applications of this technique which, it is hoped, may contribute greatly to the study of key aspects of high-level vision. Building on results from psychophysical studies of perceptual onset, priming, and hysteresis, as well as findings from a magnetoencephalographic study using RISE, this thesis explores the use of RISE in characterizing the perceptual markers and neural substrates of object and face perception. In addition, this thesis examines the issue of object perception and, in particular, robust face perception, within the context of the cortical representations that may underly them, presenting and evaluating a simple, well-motivated image coding scheme based on ordinal relations.

Pełny tekst źródłaThe purpose of vision is to find behaviorally relevant structure in the ever-flowing chaos of sensory input. In the primate, this goal is achieved by a hierarchy of cortical areas that extract increasingly complex forms of information from the light arriving at the retina. Despite success characterizing the early stages of this pathway — the retina, the lateral geniculate nucleus, and primary visual cortex (V1) — we have a poor understanding of how transformations in later stages yield selectivity for the complex shapes and objects that primates readily recognize.
According to a classical, constructionist view, the later stages of the visual system assemble elementary inputs — like the oriented features encoded by V1 — into larger and more complex combinations, capturing the structural relationships that determine the visual world. But this approach has stumbled on the enigmatic second visual area, V2, whose neurons defy our intuitions about how to begin segmenting scenes and encoding the shapes of objects.
In this thesis we develop a framework for the study of intermediate visual processing in the primate, focused on computation and representation in area V2. Rather than try to predict the responses of visual neurons to arbitrary inputs, we test hypotheses about their function by generating targeted experimental stimuli. The stimuli we use reflect the messy statistical reality of natural images, rather than intuitions about object construction. We identify novel responses properties in macaque and human V2 that robustly differentiates it from V1. We propose mechanistic explanations for these properties by contextualizing them among existing models of hierarchical computation. And we link these properties to several perceptual capabilities -- and limits -- that appear to depend specifically on processing in V2, and imply striking consequences for everyday vision.

Pełny tekst źródłaI represented a person’s stories and memories of childhood through the material called glass, and found a method to approach personal stories.
To do this, the medium to express my conception that is express of the personal experience and extreme situation on glass was based. The most significant point of study was realizing the nature of emotions and meanings within a person’s life. As well as special instruments and to analyze whether it is an appropriate expression.
Accordingly with this, I collected individual stories from Zili and tried to comprehensively understand the cause behind. For that I approached different cases of psychology theory to compare. After I analyzed the colour and object that relate to memories or the person. Expression of artefact I created from foundational theory through my perspective. I represented in magnification of memories as an expression on glass artefacts for respect of peoples diversity life.
This led me to make more concrete context in practical work and theoretical tool as well.

My thesis investigates using a graphical representation of user interfaces - screenshots - as a direct visual reference to support various kinds of applications. We have built several systems to demonstrate and validate this idea in domains like searching documentation, GUI automation and testing, and cross-device information migration. In particular, Sikuli Search enables users to search documentation using screenshots of GUI elements instead of keywords. Sikuli Script enables users to programmatically control GUIs without support from the underlying applications. Sikuli Test lets GUI developers and testers create test scripts without coding. Deep Shot introduces a framework and interaction techniques to migrate work states across heterogeneous devices in one action, taking a picture. We also discuss challenges inherent in screenshot-based interactions and propose potential solutions and directions of future research.
