Proceedings of 1999 International Symposium on Nonlinear Theory and its Applications(NOLTA99), vol. 2, pp. 863--866, 1999.


We investigate an energy function for MLP called superposed energy. Applying to autoassociative learning of a sandglass-type MLP, it can adaptively adjust the effective number of the bottleneck-layer units to the intrinsic dimensionality of nonlinear data, and the optimal dimensionality reduced representation can be extracted after learning.
