| Abstract(in English) | In the previous work, we proposed the "PaLM-Tree" which is a kind of linear regression tree. It improves some drawbacks which the conventional linear regression tree method have. When it is applied for estimating a complex nonlinear mapping, it splits the input space into too much regions. In such case, the generalization performance of the PaLM-tree tends to be worse. In order to improve the generalization performance of the PaLM-tree, we proposed a MDL-based nonlinear regression tree. Instead of using linear regression functions, this method uses polynomial functions. Furthermore, it utilizes MDL criterion to decide the degree of polynomial and the splitting points. Through the experiments on function estimation problems including artifial data and actual data, we confirmed the advantages of the proposed method. |
