Outline of Final Research Achievements

We developed a learning method of mixture models, which unifies existing methods such as convex clustering and kernel vector quantization. We provided an interpretation of this method as an optimization problem for the evaluation of the rate-distortion function. The rate-distortion function indicates the performance of optimal lossy data compression systems. We evaluated rate-distortion functions of practical loss functions such as absolute-log distortion and epsilon-insensitive distortion measures. We also evaluated the performance of an online prediction algorithm to provide an efficient method to approximate the optimal prediction algorithm.
