내용요약:

Deep learning is a hot topic of research, since its performance has been proved outstanding. Lots of ingenious ideas are involved in it, so that it is difficult to understand why it works so well. We need theoretical elucidation why it works so well. Here we revisit a classical theory of self-organization of a layered network and its characteristics. It can be generalized to a self-organizing neural field. We study dynamics of self-organization of a neural field. We then compare it with the restricted Boltzmann machine, by studying dynamics of learning of a simple restricted Boltzmann machine. We further touch upon the comparison with the autoencoder. This talk does not give a completed theory but presents half-baked ideas on deep learning.
