| Abstract(in English) | Ensemble learing is a method for constructing a strong crassifier from multiple weak classifiers. In this method, the accuracy of the strong classifier is improved, however, the classification speed and memory consumption degenerate. This is because that the strong classifier requires outputs of all weak classifiers for a single input. Our approach consists of two ideas : decomposing the input space into boxes and selecting the best classifier for each box from a certain classifier set. In this approach, since a single classifier is selected for a single input, the classification speed is almost equivalent to that of a weak classifier. Despite the fast classification speed, the accuracy will be improved, because the best classifier is selected for each box. The problem is "how to decompose the input space" and "how to select the best classifier". We propose some box decomposition and classifier selection methods and verify them through experiments. |
