Técnicas de redução de instâncias: ATISA e SSMA2
… primeira delas, ATISA (Adaptive Threshold-based Instance Selection Algorithm), mantém instâncias com base em um critério que usa a distância de cada instância ao seu inimigo mais próximo como um limiar. Essa característica prioriza instâncias próximas às fronteiras de decisão, que são mais …

Estudio de métodos de selección de instancias
En la tesis se ha realizado un estudio de las técnicas de selección de instancias: analizando el estado del arte y desarrollando nuevos métodos para cubrir algunas áreas que no habían recibido la debida atención hasta el momento. Los dos primeros capítulos presentan nuevos métodos de selección de …

Generation and analysis of segmentation trees for natural images
… pairs. Finally, we propose a novel multiple instance learning (MIL) method. In MIL, in contrast to classical supervised learning, the entities to be classified are called bags, each of which contains an arbitrary number of elements called instances. We propose an additive model for bag …

Implementation of Multiple-Instance Learning in Drug Activity Prediction
… a variant of supervised learning, named multiple-instance learning. A single molecule, treated as a bag of conformers, is biologically active if and only if at least one of its conformers, treated as an instance, is responsible for the observed bioactivity; and a molecule is inactive if none of …
