摘要
En 中文
A binary factorial code is a transformation that maps the input space into a binary string with independent bits. We apply independent component analysis, formulated as a density search, to the pursuit of such a code by considering a set of desired output bi-modal density functions. The idea is tested on a real image with the coder used also in a reversed order as a generative model. The results are also compared to a principal component analyzer. Fantasy blocks of the image transforms provide interesting clues on the nature of the learned representations. (C) 1998 Elsevier Science B.V. All rights reserved.
