Research Abstract

The purpose of this project is to study the method for visualizing a picture in the mind of a human formed from experience and learning by using machine learning. More specifically, we visualize a picture for information science and computer science by using the statistical mechanical method. As a result, we visualize a picture for various systems such as associative memory model with synaptic depression, combinatorial optimization problem such as K satisfiability problem, and the information processing with quantum fluctuation.
