Application of recurrent and deep neural networks in classification tasks

Abstract: As Redes Neurais Artificiais (RNAs) tem sido utilizadas nas soluções de variados problemas, dentre eles, os que envolvem tomada de decisões. Neste escopo, o objetivo desta pesquisa é apresentar uma ferramenta que dê suporte ao processo de decisão para seleção de cultivares de vinho e avaliação de carros, por meio da utilização de RNAs multilayer perceptron, profundas e recorrentes. Verificando-se sua eficácia e a melhor convergência, por meio do Modelo de Validação Cruzada. Os resultados elencados indicam a ef… Show more

“…Each image contained an arbitrary number of extracted features. Knowing that a Recurrent Neural network (RNR) [42] can take a sequence of arbitrary length and produce a single output, all the extracted features are used as input to an RNR with two Long Short-Term Memory (LSTM) layers. The final model achieved good classification performance with an AUC of 96%, compared with 86% for expert pathologists and only 41% for students.…”
