| Abstract(in English) | Active Search is a method which detects objective patterns from large data sets and achieves high speed and accuracy. It is widely used in various search problems such as searches for visual or acoustic patterns. However, it is not well known what kinds of patterns are suitable for Active Search. This study considers the efficiency and the accuracy of Active Search. We calculated an expectation of the width, in which matching processes are skipped, as a measure of efficiency. Additionally, we propose a measure of entropy for estimation of the accuracy. Both measures are tested using randomly generated sequences. |
