1. Contributions to projection pursuit learning / Contribuições para o aprendizado por busca de projeção
The production of parsimonious models is a common demand on a wide variety of engineering problems, as in the design of embedded systems. Constructive algorithms for supervised learning have shown to be effective methodologies for the synthesis of parsimonious artificial neural networks, with high levels of accuracy and generalization capability, though requ

2. Independent component analysis applied to separation of audio signals. / Análise de componentes independentes aplicada à separação de sinais de áudio.
This work studies Independent Component Analysis (ICA) for instantaneous mixtures, applied to audio signal (source) separation. Three instantaneous mixture separation algorithms are considered: FastICA, PP (Projection Pursuit) and PearsonICA, presenting two common basic principles: sources must be statistically independent and non-Gaussian. In order to analy

3. From paragraph to graph: Latent semantic analysis for information visualization
Most techniques for relating textual information rely on intellectually created links such as author-chosen keywords and titles, authority indexing terms, or bibliographic citations. Similarity of the semantic content of whole documents, rather than just titles, abstracts, or overlap of keywords, offers an attractive alternative. Latent semantic analysis pro
