Learning Machine having Curiosity -- Sequential Learning and Model Selection under Unstable Environments --
Koichiro Yamauchi (Chubu University) NC2009-75
Abstract (in Japanese) (See Japanese page) 
(in English) In this research, an weighted error function for the learning of RBFNN
under virtual concept drift environments is proposed.
Under such environments, the prior distribution of
learning samples is changing over time so that online learning tasks
usually cause catastrophic forgetting.
Such environments are parts of {\it covariate shift}.

First of all, a statistical model of such environments is constructed.
Then, we applied the learning strategies under covariate-shift using the
statistical model.
Moreover, a weighted Automatic Relevance Detection (ARD) is derived to
calculate the predictive distribution of output values.
The method also provides the model selection criterion.
