Rede neural não supervisionada baseada em transformada Karhunen-Loève para processamento, compressão e reconhecimento de imagens
(European Space Agency, (Special Publication) ESA SP, 1997-02-01) [Artigo]
The merit of the Karhunen-Loève transform is well known. Since its basis is the eigenvector set of the covariance matrix, a statistical, not functional, representation of the variance in pattern ensembles is generated. By ...
Oriented texture classification based on self-organizing neural network and Hough transform
(ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings, 1997-01-01) [Trabalho apresentado em evento]
This paper presents a technique for oriented texture classification which is based on the Hough transform and Kohonen's neural network model. In this technique, oriented texture features are extracted from the Hough space ...
Feedforward neural networks based on PPS-wavelet activation functions
(Ii Workshop on Cybernetic Vision, Proceedings, 1997-01-01) [Trabalho apresentado em evento]
Function approximation is a very important task in environments where computation has to be based on extracting information from data samples in real world processes. Neural networks and wavenets have been recently seen ...
Activation function study for wavelet network
(Proceedings of SPIE - The International Society for Optical Engineering, 1997-12-01) [Trabalho apresentado em evento]
The main purpose of this paper is to investigate theoretically and experimentally the use of family of Polynomial Powers of the Sigmoid (PPS) Function Networks applied in speech signal representation and function approximation. ...
