Abstract
The method is based on a deterministic on-line design technique (similar to the Kohonen learning scheme) which incorporates principles of stochastic relaxation. In contrast to the Kohonen winner-take-all competition between the candidate codevectors, it performs a 'soft' competition where each codevector is assigned a winning score and all codevectors are updated simultaneously according to these scores. A temperature schedule is used to control the speed of convergence versus the quality of the codebook.ETX
