Full textA investigação aqui relatada trata da concepção de elementos estruturantes para ampliar as oportunidades de intervenção pelo professor em um contexto de aprendizagem de programação em grupo. A partir de uma série de estudos de caso com turmas de calouros em cursos de computação, foi desenvolvida a sistematização de práticas, metodologias e tecnologias em uma abordagem para apoiar a aprendizagem de programação em grupo, baseada em três frentes de investigação: pressupostos pedagógicos, ferramentas LMS e métodos de colaboração. O eixo teórico referente à aprendizagem é a teoria de desenvolvimento cognitivo de Piaget, aliada a técnicas conhecidas de programação em grupo utilizadas no ensino de graduação em disciplinas introdutórias de programação. As ferramentas computacionais são utilizadas para monitorar e intervir durante o processo de aprendizagem. Nesse contexto, ambientes CSCL incentivam a colaboração e regulam as práticas desejadas. Nesta tese, outras tecnologias, como linguagens para representação de agentes e identificação de padrões são agregadas a eles para melhorar o acompanhamento e facilitar a intervenção. Por fim, como método de colaboração, é proposto um esquema progressivo de aprendizagem de programação em grupo, que auxilia os alunos a gradativamente adotarem práticas colaborativas na resolução de exercícios e que pode ser formalizado para incorporação a plataformas automatizadas.
The research reported here deals with devising structuring elements that may broaden intervention opportunities from the teacher in a context of group programming learning. Based on a set of case studies with freshmen in computing courses a systematization for practices, methods and technologies was developed producing an approach for supporting group programming based in three investigation paths: pedagogical assumptions, CSCL environments and collaboration methods. The main learning rationale is Jean Piaget’s Cognitive Development Theory, used alongside group programming techniques commonly applied in undergraduate introductory programming courses. Computational tools are used to monitor and intervene during learning process and in such context, CSCL environments encourage collaboration and regulate expected practices. In this thesis other technologies like languages for agent representation and patterning identification are also exploited for improving control and facilitate interventions. Finally, as collaboration method, it is proposed a Programming Progressive Learning Scheme that helps students to adopt collaborative practices when solving exercises and that can be formalized to be used with automated platforms.

Understanding the diversity and abundance of microbial populations is paramount to the health of humans and the environment. Estimating the diversity of these populations from whole metagenome shotgun (WMS) sequencing reads is difficult because the size of these datasets and overlapping reads limit what kinds of analysis we can do. Current methods require matching reads to a database of known microbes. These methods are either too slow or lack the sensitivity needed to identify novel species. We propose a convolutional neural network (CNN) based approach to metagenomic binning that embeds reads into a low-dimensional vector space based on taxonomic classification. We show that our method can get the speed and sensitivity necessary taxonomic classification. Our method was able to achieve 13% accuracy on identifying novel genus of bacteria as compared to 7% accuracy of k-mer embedding. At the same time, the speed of our method is within an order of magnitude of that of k-mer embedding, making it viable as a metagenomic analysis tool.

This thesis details a new vantage point for attacking longstanding problems in machine learning. We use tools from computational complexity theory to make progress on problems from computational learning theory. Our methods yield the fastest and most expressive algorithms to date for learning several fundamental concept classes: * We show that any s-term DNF over n variables can be computed by a polynomial threshold function of order O(n1/3 log s). As an immediate consequence we obtain the fastest known DNF learning algorithm which runs in time 2O(n1/3). * We give the first polynomial time algorithm to learn an intersection of a constant number of halfspaces under the uniform distribution to within any constant error parameter. We also give the first quasipolynomial time algorithm for learning any function of a constant number of halfspaces with polynomial bounded weights under any distribution. * We give an algorithm to learn constant-depth polynomial-size circuits augmented with majority gates under the uniform distribution using random examples only. For circuits which contain a polylogarithmic number of majority gates the algorithm runs in quasipolynomial time. Under a suitable cryptographic assumption we show that these are the most expressive circuits which will admit a non-trivial learning algorithm. Our approach relies heavily on giving novel representations of well known concept classes via complexity theoretic reductions. We exploit the fact that many results in computational learning theory have a complexity theoretic analogue or implication. As such,
(cont.) we also obtain new results in computational complexity including (1) a proof that the 30 year old lower bound due to Minsky and Papert [88] on the degree of a perceptron computing a DNF formula is tight and (2) improved constructions of pseudo-random generators, mathematical objects which play a fundamental role in cryptography and derandomization.

Full textDiabetisk näthinnesjukdom (DR) är en komplikation av diabetes och är en sjukdom som påverkar ögonen. Det är en av de största orsakerna till blindhet i västvärlden. Allt eftersom antalet människor med diabetes ökar, ökar även antalet med diabetisk näthinnesjukdom. Detta ställer högre krav på att bättre och effektivare resurser utvecklas för att kunna upptäcka sjukdomen i ett tidigt stadie, vilket är en förutsättning för att förhindra vidareutveckling av sjukdomen som i slutändan kan resultera i blindhet, och att vidare behandling av sjukdomen effektiviseras. Här spelar datorstödd diagnostik en viktig roll. Syftet med denna studie är att undersöka hur ett faltningsnätverk, tillsammans med överföringsinformation, kan prestera när det tränas för multiklass gradering av diabetisk näthinnesjukdom. För att göra detta användes ett färdigbyggt och färdigtränat faltningsnätverk, byggt i Keras, för att fortsättningsvis tränas och finjusteras i Tensorflow på ett 5-klassigt DR dataset. Totalt tjugo träningssessioner genomfördes och noggrannhet, sensitivitet och specificitet utvärderades i varje sådan session. Resultat visar att de uppnådda noggranheterna låg inom intervallet 35% till 48.5%. Den genomsnittliga testsensitiviteten för klass 0, 1, 2, 3 och 4 var 59.7%, 0.0%, 51.0%, 38.7% respektive 0.8%. Vidare uppnåddes en genomsnittlig testspecificitet för klass 1, 2, 3 och 4 på 77.8%, 100.0%, 62.4%, 80.2% respektive 99.7%. Den genomsnittliga sensitiviteten på 0.0% samt den genomsnittliga specificiteten på 100.0% för klass 1 (mild DR) erhölls eftersom CNN modellen aldrig förutsåg denna klass.

Full textFelaktiga annoteringar kan sänka klassificeringsprestanda.Speciellt för djupa nätverk kan detta leda till dålig generalisering. Nyligen har brusrobust djup inlärning överträffat andra inlärningsmetoder när det gäller hantering av komplexa indata Befintligta resultat från djup inlärning kan dock inte tillhandahålla rimliga viktomfördelningskriterier. För att hantera detta kunskapsgap och inspirerat av domänanpassning föreslår vi en ny robust djup inlärningsmetod som använder omviktning. Omviktningen görs genom att minimera den maximala medelavvikelsen mellan förlustfördelningen av felmärkta och korrekt märkta data. I experiment slår den föreslagna metoden andra metoder. Resultaten visar en stor forskningspotential för att tillämpa domänanpassning. Dessutom motiverar den föreslagna metoden undersökningar av andra intressanta problem inom domänanpassning genom att möjliggöra smarta omviktningar.

Full textThe relationship between the big five personality traits, Extraversion, Agreeableness Neuroticism, Conscientiousness and Openness to Experience and deep and surface approaches to learning forms the basis of this article. The findings of a research study in this milieu will be presented to prove that earlier studies in this field have been upheld, but that an important deviation has occurred on certain levels of personality. A students way of learning implies the type of learning that is taking place. Ultimately we as lecturers want to encourage deep learning as this stimulates retention of information, important in production of students that are ready for employment.

Full textThe impressive growth, in the past decades, of the number of vehicles on the road has not come without its share of negative impacts on society. Even though vehicles play an active role in the economical development of urban regions around the world, they unfortunately also have negative effects on businesses as the poor efficiency of the traffic ow results in important losses in productivity each day. Moreover, numerous concerns have been raised in relation to the safety of passengers, as automotive transportation is still among the first causes of accidental casualties in developed countries. In recent years, environmental issues have also been taking more and more place in the mind of customers, that now demand energy-efficient vehicles that limit the impacts on the environment. Of course, both the governments of industrialized countries and the vehicle manufacturers have been aware of these problems, and have been trying to develop technologies in order to solve these issues. Among these research efforts, the field of Intelligent Transportation Systems (ITS) has been gathering much interest as of late, as it is considered an efficient approach to tackle these problems. ITS propose to integrate advanced electronic systems in the development of intelligent solutions designed to address the current issues of automotive transportation. This thesis focuses on a sub-field ITS since it studies the resolution of these problems through the development of Intelligent Vehicle (IV) systems. In particular, this thesis proposes a relatively novel approach for the design of such systems, based on modern machine learning. More specifically, it shows how reinforcement learning techniques can be used in order to obtain an autonomous vehicle controller for longitudinal vehiclefollowing behavior. Even if these efforts are still at a preliminary stage, this thesis illustrates the potential of using these approaches for future development of \intelligent" vehicles.

Full textDet huvudsakliga målet med denna rapport var att undersöka och demonstrera hur maskininlärningsmetoder kan användas för att skapa exakta och användbara bostadsvärderingsmodeller, med fokus på Stockholmsmarknaden. Vidare analyseras även om och hur olika attribut, inklusive lägenhetsbeskrivningar, påverkar priset på lägenheten. Exakt och effektiv värdering skulle inte bara vara användbart för privatpersoner, som vill ha en snabb och precis värdering, men också för mäklare och skattemyndigheter. För detta ändamål applicerades och utvärderades ett flertal metoder, varav den bästa uppnådde en MAPE på 6.37%. Avgift, byggnadsår och ett flertal olika geografiskt relaterade variabler var bland de viktigaste vad gäller lägenhetspriset. För det första drogs slutsatsen att maskininläarningsmetoder kan producera exakta och användbara bostadsvärderingsmodeller, med högre precision än mäklares värderingar. För det andra identifierades geografiskt baserade attribut som mest väsentliga, medan skicket på badrum och kök inte var mindre viktigt än förväntat. Avslutningsvis kan konstateras att även om modellerna som utvecklades i rapporten inte lyckades utnyttja lägenhetsbeskrivningarna, indikerar resultatet att de innehåller värdefull information som potentiellt kan utnyttjas, givet att en mer rigorös förbehandling och analys av datan utförs.

Full textDenna uppsats undersöker hur tre olika maskininlärningsmodeller presterar på kardinalitetsuppskattning för sql förfrågningar till en databas. Alla tre modeller utvärderades på tre olika datauppsättningar. Modellerna fick både behandla förfrågningar från en tabell, samt en sammanslagning mellan två tabeller. Postgresql's egna kardinalitetsestimerare användes som referenspunkt. De utvärderade modellerna var följande: artificiella neurala nätverk, random forests och extreme gradient boosted trees. En slutsats var att den modellen som utförde uppgiften bäst var extreme gradient boosted trees med en tweedie-regression förlustfunktion. Såvitt författaren vet är det här första gången den här typen av extreme gradient boosted tree används på denna typ av problem.

Full textThe aim of this thesis is to minimize the performance loss of a one-class detection system when it encounters a data distribution change. The idea is to use transfer learning approach to transfer learned information from related old task to the new one. According to the practical applications, we divide this transfer learning problem into two parts, one part is the transfer learning in homogenous space and the other part is in heterogeneous space. A multi-task learning model is proposed to solve the above problem; it uses one parameter to balance the amount of information brought by the old task versus the new task. This model is formalized so that it can be solved by classical one-class SVM except with a different kernel matrix. To select the control parameter, a kernel path solution method is proposed. It computes all the solutions along that introduced parameter and criteria are proposed to choose the corresponding optimal solution at given number of new samples. Experiments show that this model can give a smooth transition from the old detection system to the new one whenever it encounters a data distribution change. Moreover, as the proposed model can be solved by classical one-class SVM, online learning algorithms for one-class SVM are studied later in the purpose of getting a constant false alarm rate. It can be applied to the online learning of the proposed model directly
