ScholarBank@NUS Repository. https://doi.org/10.1109/TNN.2007.891193 | Abstract: | Adaptively determining an appropriate number of principal directions for principal component analysis (PCA) neural networks is an important problem to address when one uses PCA neural networks for online feature extraction. In this letter, inspired from biological neural networks, a single-layer neural network model with lateral connections is proposed which uses an improved generalized Hebbian algorithm (GHA) to address this problem. In the proposed model, the number of principal directions can be adaptively determined to approximate the intrinsic dimensionality of the given data set so that the dimensionality of the data set can be reduced to approach the intrinsic dimensionality to any required precision through the network. © 2007 IEEE. | Source Title: | IEEE Transactions on Neural Networks | URI: | http://scholarbank.nus.edu.sg/handle/10635/55600 | ISSN: | 10459227 | DOI: | 10.1109/TNN.2007.891193 |
