| Abstract(in English) | In online character recognition based on elastic matching, such as DP matching, many of misrecognitions are often due to over fitting, which is the phenomenon that a wrong reference pattern is closely fitted an input pattern. In this report, a technique to suppress those misrecognitions is proposed, where frequent deformations of each category, called eigen-deformations, are utilized. In case of overfitting, the matching between the two patterns will diverge from the eigen-deformations of the category of the reference pattern. Thus, the overfitting can be detected by evaluating the divergence. The result of a recognition experiment showed the usefulness of the proposed technique. |
