Di erent Strategies for Combining
نویسنده
چکیده
For Diagnostic Problem Solving Methods, appropriate methods and knowledge bases require considerable time for development. Graphical knowledge interfaces and reuse of Problem Solving Methods (PSM) can increase user performance of building knowledge bases. Furthermore classiication accuracy is also imporant which can be increased by combinations of diierent PSM. We combined three algorithms of the Shell{Kit D3 in diierent ways, to improve evaluation results of PSM applied previously while reusing the same knowledge base. Evaluation results demonstrated limited gains which might be increased by further methological reenement.

An EÆcient Boosting Algorithm for Combining Preferences
The problem of combining preferences arises in several applications, such as combining the results of di erent search engines. This work describes an eÆcient algorithm for combining multiple preferences. We rst give a formal framework for the problem. We then describe and analyze a new boosting algorithm for combining preferences called RankBoost. We also describe an eÆcient implementation of t...

Multi-strategy planning focuses on the selection and combination of di erent problem solving methods. Since planning is intractable in complex domains, researchers have developed di erent methods to restrict, restructure, or reorder the search space and to search the new space. These reformulations of the search space are based on assumptions about the domain or other features of the task such ...

متن کاملCombining ANNs to improve phone recognition
In applying neural networks to speech recognition, one often nds that slightly di erent training con gurations lead to signi cantly di erent networks. Thus di erent training sessions using di erent setups will likely end up in \mixed" network con gurations representing di erent solutions in di erent regions of the data space. This sensitivity to the initial weights assigned, the training parame...

This paper deals with coordinating behaviour in a multi-autonomous robot system. When two or more autonomous robots must interact in order to accomplish some common goal, communication between the robots is essential. Di erent inter-robot communications strategies give rise to di erent overall system performance and reliability. After a brief consideration of some theoretical approaches to mult...
