For users' specialization, such as Handwriting, Voice,Drawing Styles, the system is hard to adapt to all users. SVM-based incremental learning can find the most basic fea-ture of different users and cast away the special user's character, so this method can adapt the different users withoutover fitting. In this paper, the repetitive learning strategy and other two incremental learning algorithms are presentedfor comparison. Based on theoretical analysis and experimental results, we draw the conclusion that SVM-based incre-mental learning can solve the user conflict problem.展开更多

This article analyzes the interoperability problem of Agent deeply. It first discusses the main research work about agent interoperability,namely OMG's MAF specification and the set of specifications of FIPA,and points out their drawbacks. Then a research model covering the main aspects of interoperability in Agent environment is brought up,and a reference model for agent system is also provided,which fully corresponds with the research model for agent interoperability.The two models have nice universality and adaptability,and provide a practical reference for building an Agent system with good interoperability.展开更多

Handwritten signature verification is an effective one. This paper introduces the design and implementation of an on-line handwritten signature verification system which is based on dynamic programming matching algorithm and give a brief evaluation of its performance. The performance of the system is satisfying according to the experiment.展开更多
