| Research Abstract |
In this research, we developed a machine learning method which enables a robot to obtain several unit motions from unsegmented human motion. In the method, the learning architecture reduces the dimensionality of observed time series data using singular vector decomposition, models the output data using Switching AR Model (SARM). After SARM encodes the data to code strings, a keyword extraction method extract unit words from the strings based on minimal description length criteria. The extracted words are revealed to be characteristic unit motions.
