点击翻译按钮获取中文摘要

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.
