Full textThe use of language is one of the defining features of human cognition. Focusing here on two key features of language, productivity and robustness, I examine how basic questions regarding linguistic representation can be approached with the help of probabilistic generative language models, or PGLMs. These statistical models, which capture aspects of linguistic structure in terms of distributions over events, can serve as both the product of language learning and as prior knowledge in real-time language processing. In the first two chapters, I show how PGLMs can be used to make inferences about the nature of people's linguistic representations. In Chapter 1, I look at the representations of language learners, tracing the earliest evidence for a noun category in large developmental corpora. In Chapter 2, I evaluate broad-coverage language models reflecting contrasting assumptions about the information sources and abstractions used for in-context spoken word recognition in their ability to capture people's behavior in a large online game of “Telephone.” In Chapter 3, I show how these models can be used to examine the properties of lexicons. I use a measure derived from a probabilistic generative model of word structure to provide a novel interpretation of a longstanding linguistic universal, motivating it in terms of cognitive pressures that arise from communication. I conclude by considering the prospects for a unified, expectations-oriented account of language processing and first language learning.

In this thesis, the temporal complexity in children's stories is analyzed to better understand the development of children's perception of time. The temporal complexity increases both in greater deviations from a chronological presentation of events, as well as an increase in the different kinds of temporal relations between events. Tools to analyze and display the temporal complexity were developed and are used to demonstrate an increase in temporal complexity as the grade level increases. The results from this were then used to determine the appropriate reading material for a given grade of sample stories. Unlike the normal assessments methods, that use only the word and sentence complexity, this thesis takes into account both the the semantic contents of the story and the cognitive ability of the child.

Full textIncludes bibliographical references (p. 77-79).
Curve fitting is a widely employed, useful modeling tool in several financial, scientific, engineering and data mining applications, and in applications like sensor networks that need to tolerate missing or noisy data. These applications need to both fit functions to their data using regression, and pose relational-style queries over regression models. Unfortunately, existing DBMSs are ill suited for this task because they do not include support for creating, representing and querying functional data, short of brute-force discretization of functions into a collection of tuples. This thesis describes FunctionDB, a novel DBMS that extends the state of the art. FunctionDB treats functions output by regression as first-class citizens that can be queried declaratively and manipulated like traditional database relations. The key contributions of FunctionDB are a compact, algebraic representation for regression models as piecewise functions, and an algebraic query processor that executes declarative queries directly on this representation as combinations of algebraic operations like function inversion, zero finding and symbolic integration. FunctionDB is evaluated on two real world data sets: measurements from a temperature sensor network, and traffic traces from cars driving on Boston roads. The results show that operating in the functional domain has substantial accuracy advantages (over 15% for some queries) and order of magnitude (10x-100x) performance gains over existing approaches that represent models as discrete collections of points. The thesis also describes an algorithm to maintain regression models online, as new raw data is inserted into the system. The algorithm supports a sustained insertion rate of the order of a million records per second, while generating models no less compact than a clairvoyant (offline) strategy.

Generative models are venerated as full probabilistic models that randomly generate observable data given a set of latent variables that cannot be directly observed. They can be used to simulate values for variables in the model, allowing analysis by synthesis or model criticism, towards an iterative cycle of model specification, estimation, and critique. However, many datasets represent a combination of several viewpoints - different ways of looking at the same data that leads to various generalizations. For example, a corpus that has data generated by multiple people may be mixtures of several perspectives and can be viewed with different opinions by others. It isn't always possible to represent the viewpoints by clean separation, in advance, of examples representing each perspective and train a separate model for each point of view. In this thesis, we introduce lensing, a mixed-initiative technique to (i) extract lenses or mappings between machine-learned representations and perspectives of human experts, and (2) generate lensed models that afford multiple perspectives of the same dataset. We explore lensing of latent variable model in their configuration, parameter and evidential spaces. We apply lensing to three health applications, namely imbuing the perspectives of experts into latent variable models that analyze adolescent distress and crisis counseling.

Full textI dagens samhälle ökar populariteten för röstbaserade tjänster. Att kunna förse användare med röster de tycker om, för att fånga och behålla deras uppmärksamhet, är därför viktigt för att förbättra användarupplevelsen. Att hitta ett effektiv sätt att representera röster, så att likheter mellan dessa kan jämföras, är därför av stor nytta. Inom fältet språkteknologi i maskininlärning har stora framstegs gjorts genom att skapa representationer av ord från de inre lagren av neurala nätverk, så kallade neurala nätverksinbäddningar. Dessa representationer har visat sig innehålla semantiken av orden. Denna uppsats avser att undersöka huruvida liknande representationer kan hittas för ljuddata i form av berättarröster från ljudböcker, där likhet mellan röster fångas upp. För att undersöka detta utvecklades och utvärderades två faltningsnätverk som använde sig av spektrogramrepresentationer av röstdata. Den ena modellen är konstruerad som en vanlig klassificeringsmodell, tränad för att skilja mellan uppläsare i datasetet. Den andra modellen använder parvisa förhållanden mellan datapunkterna och en Kullback–Leibler divergensbaserad optimeringsfunktion, med syfte att minimera och maximera skillnaden mellan lika och olika par av datapunkter. Från dessa modeller används representationer från de olika lagren av nätverket för att representera varje datapunkt under utvärderingen. Både en objektiv och subjektiv utvärderingsmetod används. Under den objektiva utvärderingen undersöks först om de funna representationerna är distinkta för olika uppläsare, sedan undersöks även om dessa fångar upp information om uppläsarens kön. Den vanliga klassificeringsmodellen utvärderas också genom ett användartest, eftersom den modellen nådde en storleksordning bättre resultat under den objektiva utvärderingen. Syftet med användartestet var att undersöka om de funna representationerna innehåller information om den upplevda likheten mellan rösterna. Slutsatsen är att det föreslagna tillvägagångssättet har potential till att användas för att representera röster så att information om likhet fångas upp, men att det krävs mer omfattande testning, undersökning och utvärdering. För framtida studier föreslås mer sofistikerad förbehandling av data samt att samla in och använda sig av data kring förhållandet mellan röster under träningen av modellerna.

Full textIn this thesis, we first clearly demonstrate that modeling grounding-line (the boundary between grounded and floating ice) migration depends on both the numerical approach and the physical approximation of the ice-sheet model used. Ice-sheet models prescribing the ice flux at the grounding line and using appropriate physical level and numerical approach converge to the same steady-state grounding-line position irrespective of the grid size used. However, the transient behavior of those models is less accurate than other models and leads to an overestimated grounding-line discharge. Therefore, they need to be used with particular attention on short time scales. Furthermore, the non-inclusion of vertical shear stress in those models increases the effective viscosity and gives steady-state grounding-line positions further downstream when compared to full-Stokes models.
The second major finding of this thesis is the high control of geometry (glacier width and bedrock topography) on Thwaites Glacier, one of the fastest-flowing outlet glaciers in West Antarctica. A flowline finite-difference Shallow-Shelf Approximation (SSA) model is applied to the glacier and shows that ice-flow convergence (through width parameterization) slows down the grounding-line retreat when compared to simulations where the width is constant. A new buttressing parameterization is also tested on the glacier and permits a better understanding of this effect. Finally, the three-dimensional version of the model above is applied to Thwaites Glacier and highlights the strong control of lateral variations in bedrock topography on grounding-line migration./Depuis le milieu du 20e siècle, les températures moyennes globales ont fortement augmenté principalement à cause de l'augmentation des émissions de gaz à effet de serre d'origine humaine. Les effets de ce réchauffement global récent sont déjà détectables et pourraient s'accentuer dans un futur proche si aucune mesure réelle n'est prise. La perte récente de glace en Antarctique de l'Ouest, enregistrée par mesures satellites et d'autres techniques, est préoccupante dans un monde qui se réchauffe. Une grande partie de cette perte de glace est due à la pénétration de masses d'eau chaude sous les plateformes de glace flottante dans cette région. Cela engendre une accélération de l'écoulement des glaciers émissaires et une plus grande décharge de glace vers l'océan. Ainsi, la contribution récente à la hausse du niveau de la mer de l'Antarctique de l'Ouest s'élève à environ 0.2 mm par an entre 1992 et 2011, c'est-à-dire près du tiers de la contribution des calottes glaciaires (Antarctique et Groenland). On estime que cette contribution va continuer à augmenter dans le futur proche.
Dans cette thèse, nous démontrons clairement que la modélisation de la migration de la ligne d'ancrage (frontière entre glaces posée et flottante) dépend de l'approche numérique et de l'approximation physique du modèle cryosphérique utilisé. Les modèles cryosphériques qui prescrivent le flux glaciaire à la ligne d'ancrage et qui utilisent un niveau de physique et une approche numérique appropriés convergent vers la même position d'équilibre de la ligne d'ancrage quelle que soit la taille de maille utilisée. Cependant, le comportement transitoire de ces modèles est moins précis que d'autres modèles et mène à une surestimation du flux à la ligne d'ancrage. Dès lors, ces modèles doivent être utilisés avec précaution sur de courtes périodes de temps. De plus, la non inclusion des contraintes verticales de cisaillement dans ces modèles augmente la viscosité effective et donne des positions d'équilibre de la ligne d'ancrage plus en aval en comparaison avec les modèles « full-Stokes ».
La seconde découverte majeure de cette thèse est le contrôle important exercé par la géométrie (largeur du glacier et topographie du lit rocheux) sur Thwaites Glacier, l'un des glaciers émissaires les plus rapides en Antarctique de l'Ouest. Un modèle « Shallow-Shelf Approximation » (SSA) résolvant les différences finies le long d'une ligne d'écoulement est appliqué au glacier et montre que la convergence de l'écoulement glaciaire (au travers de la paramétrisation de la largeur) ralentit le retrait de la ligne d'ancrage comparé aux simulations où la largeur est constante. Une nouvelle paramétrisation de l'effet arc-boutant est testée sur le glacier et permet de mieux comprendre cet effet. Finalement, la version en trois dimensions du modèle ci-dessus est appliquée à Thwaites Glacier et met en évidence le contrôle important des variations latérales de l'altitude du lit rocheux sur la migration de la ligne d'ancrage.

This thesis presents work focused on the creation of a sociable space for communication online. Sociable communication requires the ability to converse with others using simple and meaningful mechanisms, supporting flexibility and expressiveness. Equally important is the ability for people to read the space they inhabit and make sense of it in socially significant ways, such as people watching to observe others' interests and interaction styles. A third key to sociable communication is emphasis on identity and embodiment, giving participants a strong sense of themselves and others through their online representations. These issues are approached through research in areas ranging from sociology to urban architecture, directed at finding bases for the design of capabilities that are useful and engaging in the context of computer support for distributed multiparty communication. The result of this research is Talking in Circles, a graphical audio conferencing environment that employs abstract graphics for representation and provides lightweight access to multiple expressive modes. This thesis discusses foundations for work towards sociable communication online as well as the design and implementation processes involved in the creation of the Talking in Circles system. User experiences with the system, lessons learned and directions for further research into sociable communication are then detailed.

Full textI denna rapport talas det om användbarhetsexpertens roll som representant för användaren,medlare av termen användbarhet samt medlare mellan användaren och andra yrkesroller i en systemutvecklingsprocess. Denna roll har många gånger en tendens till att inte få tillräckligt med gehör av andra yrkesroller i utvecklingsprojekt. Det finns flera olika faktorer som kan bidra till detta. Vad som framkom i resultatet var en bekräftelse på att användbarhetsexpertens
roll är viktig i fråga om representering och medling. Vad gäller faktorn samarbete anser respondenterna att samarbetet för det mesta fungerar bra mellan dem och andra yrkesroller. Samarbete ses därmed inte som en faktor som påverkar gehöret för en användbarhetsexperts roll i systemutvecklingsprocesser. Respondenterna tycker däremot att de inte alltid får gehör för sin roll som användbarhetsexpert fast att de tycker att samarbetet med andra yrkesroller fungerar bra. En faktor som bidrar till
detta är den svårdefinierade termen användbarhet.

Full textEffektiva visuella formdeskriptorer för handigenkänning. Denna masteruppsats undersöker handposestimering där en 2D bild används för att rekonstruera en handpos, vilken beskrivs av hur handlederna är vinklade. Handposestimering har många potentiella användningsområden varav några är teckenspråksigenkänning, robotinlärning från demonstrationer, men även människa-datorinteraktion i allmänhet. För att göra översättningen från bild till handpos extraheras först bildegenskaper (image-features) varpå en mappning till posrummet (alla möjliga poser) konstrueras. Den önskade egenskapen hos en mappning till posrummet är framförallt att den är one-to-one,men i verkligheten innehåller den normalt tvetydigheter. Detta beror bland annat på att bildegenskaperna inte beskriver själva handposen utan enbart formen av 2D projektionen av en hand. Förutom det så kan händer även skymma delar av sig själva vilket också leder till tvetydigheter i mappningen från bildegenskaper till posrummet. Målet med denna uppsats är ändå att undersöka sätt att förbättra den vanligt använd bildegenskap HOG (Histogramof Oriented Gradients) genom att använda det delrum hos HOG deskriptorerna som upptas av handbilder. Den nya bildegenskapen konstrueras genom projektioner och avståndsberäkningar till linjer i HOG rummet som motsvarar handrörelser. Den föreslagna bildegenskapen testas mot HOG med NN(Nearest neighbour) regression och resultatet visar att HOG presterar bästmed den nuvarande konstruktionen av den nya bildegenskapen. Slutsatsen är dock att den nya deskriptorn, kallad MPDD för Multiple Projection and Distance dimensions, lyckas fånga det relevanta delrummet av HOG, men misslyckas med att använda informationen i denna. Detta innebär sannolikt att sättet som MPDD konstrueras på i denna mastersuppsats antagligen bör förändras även om en liknande idé kan räcka för att uppnå samma eller bättre resultat än HOG.

Years after the inception of the Radical Atoms vision, significant advances in technology have seen to dynamic tangible interfaces that bridge the biological and micromechanical to enable radical physical interaction with computation. With an increasing multi-modal complexity in such interfaces, this thesis explores a new methodologies and frameworks to designing input/output coincident and physically embodied computers. New types of Shape Changing Interfaces introduce physical perception of material properties to dynamic shape with physically accurate force feedback and introduce Radical Materiality as a way to afford physical interactions with a rendered object. Finally, the Radical Reality Test is proposed as an objective for such interfaces to eventually become indistinguishable from the physical entity or behavior they are computationally and dynamically imitating.
