Abstract: This thesis focuses on techniques that improve flexibility and accuracy of Multiple Layer Perceptron (MLP) neural network. It covers three topic???In the first topic of the thesis, I proposed three Incremental Output Learning (IOL) algorithms for incremental output learning. In the second topic, I proposed a hierarchical incremental class learning (HICL) task decomposition method based on IOL algorithms. In this method, a -class problem is divided into sub-problems. Unlike other task decomposition methods, HICL can also maintain the useful correlation within the output attributes of a problem. In the last topic, I propose two feature selection techniques a?? Relative Importance Factor (RIF) and Relative FLD Weight Analysis (RFWA) for neural network with class decomposition. These approaches involved the use of Fishera??s linear discriminant (FLD) function to obtain the importance of each feature and find out correlation among features.
