25. Aprendizado transdutivo baseado em teoria da informação e teoria do aprendizado estatístico
The machine learning problem is most frequently proposed and solved under the inductive inference paradigm, based on classical inductive principles such as the Empirical Risk Minimization (ERM) and Structural Risk Minimization (SRM). These principles are based on the attempt to create a learning rule given some finite training data. They rely on two assumpti

26. Treinamento de redes neurais artificiais baseado em sistemas de estrutura variável com taxa de aprendizado adaptativa
This work presents new algorithms for training multilayer perceptron artificial neural networks based on stability properties of sliding mode variable structure systems. The main feature of the proposed algorithms is the adaptability of the gain (learning rate), which is obtained from each update step of the network weights, without the use of heuristics met

27. Evolutionary TBL template generation
Transformation Based Learning (TBL) is a Machine Learning technique frequently used in some Natural Language Processing (NLP) tasks. TBL uses rule templates to identify error-correcting patterns. A critical requirement in TBL is the availability of a problem domain expert to build these rule templates. In this work, we propose an evolutionary approach based

28. Computação Evolutiva para a Construção de Regras de Conhecimento com Propriedades Específicas / Evolutionary Computing for Knowledge Rule Construction with Specific Properties
Most symbolic machine learning approaches use if-then know-ledge rules as the description language in which the learned knowledge is expressed. The aim of these learners is to find a set of classification rules that can be used to predict new instances that have not been seen by the learner before. However, these sorts of learners take into account the rule

29. Application of the learning styles in team formation: a study of case / Aplicação dos estilos de aprendizagem na formação de equipes: um estudo de caso
This assignment has as main aim to remark and analyse what is the influence of the learning styles, in other words, the different preferences by noticing and processing the information, in the high-performance teams formation (all the integrated members of the team are committed to the other´s learning, aiming to reach high levels of performance in a subjec

30. Rede Neural Difusa com T-normas Diferenciáveis e Interativas
Fuzzy sets are used in the representation of vague and imprecise knowledge. Neural networks, besides their computational parallelism, also have learning capabilities. The combination of such both paradigms is an attempt to congregate their benefits in an integrated system, such a fuzzy neural network. T-norms are functions that actuate like intersection and

31. Formação do professor de Matemática: entre a competência técnica e a dimensão ética. / Formation of Mathematics Teachers: between of technical skills and ethics.
Personal doubts concerning the profession of being a teacher and the work as a teacher advisor at a school elicited different general questions about the formation of mathematics teacher. This questioning is made within a multiple approach, in which technical skills are not considered apart of the social, cultural and ethical qualifications. The effective ch

32. Recurrent neural nets for networks inference of gene interactions using Markov chains / Redes neurais recorrentes para inferência de redes de interação gênica utilizando cadeias de Markov
Array technologies have made it strainghtforward to simultaneously monitor the expression pattern of thousands of genes. Thus, a lot fot data is being generated and the challenge now is to discover how to extract useful information from these data sets. Microarray data is highly specialized. It involves several variables in a nonlinear and temporal way, dema

33. Garantia de qualidade no ensino superior
The education is basic right as life and the freedom. This right has as objective to change the human being for better. For intermediary of the education the person evolves for better and develops the society with this improvement. In the educational process the human being is the object and the person of the education, at the moment to educate and when he i

34. "New approaches in machine learning for rule generation, class imbalance and rankings" / "Novas abordagens em aprendizado de máquina para a geração de regras, classes desbalanceadas e ordenação de casos"
Algoritmos de aprendizado de máquina são frequentemente os mais indicados em uma grande variedade de aplicações de mineração dados. Entretanto, a maioria das pesquisas em aprendizado de máquina refere-se ao problema bem definido de encontrar um modelo (geralmente de classificação) de um conjunto de dados pequeno, relativamente bem preparado para o a

35. Combinig classifiers using knowledge rule measures and genetic algortgms / Combinação de classificadores simbólicos utilizando medidas de regras de conhecimento e algoritmos genéticos
A qualidade das hipóteses induzidas pelos atuais sistemas de aprendizado de máquina supervisionado depende da quantidade dos exemplos no conjunto de treinamento. Por outro lado, muitos dos sistemas de aprendizado de máquina conhecidos não estão preparados para trabalhar com uma grande quantidade de exemplos. Grandes conjuntos de dados são típicos em m

36. "Educação e comunicação: pelas vias de uma didática da obra de arte" / Education and Comunication - for the ways of a Didactics of the Master Piece
This is about a theorical research, built on educational-philosophical basis, viewing to analyse the know-power device of the didactics and propose the epitemological basis to the construction of a Didactics of the Master Piece. From the post structuralism perspective, outlining Michel Foucault´s production, I tried to find some compositional conditions tha
