Study on Pattern Inference based on Positive Examples and its Application to Knowledge Discovery

本研究将模式推理视为知识发现。我们关注的是数据库中相似样例的近似检索。从大规模高维数据库中实现高效的近似检索是有效的知识发现的关键。本文的研究成果包括：多媒体高维数据库空间索引加速技术的发展及其在视频识别和程序匹配等实验系统中的应用。

This study has been dealt with pattern inference as knowledge discovery. We focus our attention on approximate retrieval of similar examples from database. For useful knowledge discovery, it is important to realize efficient approximate retrieval from large scale high-dimensional database. Results obtained in this study include development of speed-up techniques of spatial index for multimedia high-dimensional database and their application to experimental systems, such as video identification and program matching.
