INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD AND PROGRAM
First Claim
1. An information processing apparatus which performs setting of a mixture model function representing a mixture model along with adaptively adjusting the number of mixture model components included in the mixture model, the information processing apparatus comprising:
- acquisition means for acquiring a first data sample and a second data sample, both of which are composed of multi-dimensions;
mixture-model-function generation means for generating a mixture model function on the basis of the first data sample;
mixture-model-function goodness-of-fit calculation means for calculating a goodness of fit for the mixture model function on the basis of the second data sample; and
mixture-model-function update means for updating the mixture model function so as to adjust the number of model components mixed in a mixture model, which is represented by the mixture model function, on the basis of the goodness of fit for the mixture model function.
