| Abstract(in English) | Takano at al proposed the total frequency measure that finds out all frequent sequential patterns in a single large-scale data sequence. But, this measure extracts too many frequent sequential patterns which may include noisy patterns. In this paper, we propose a method that can narrow frequent patterns with a relation strength like the mutual information between elements in a sequence. This method drastically reduces the number of frequent sequential patterns. and the ratio of remaining valid sequential patterns increased. |
