Abstract (in Japanese) (See Japanese page) 
(in English) This study focuses on darknet traffic analysis and applies tensor factorization in order to detect coordinated group activities, such as a botnet.
Tensor factorization is more interpretable model than any other change point detection methods and can handle more features than matrix factorization.
Nonnegative tucker decomposition, one of the tensor factorization methods, has non-negativity constraints to avoid physically unreasonable results, but needs too much computational resources to run in real-time.
To address this problem, we propose a method for detecting group activities from the extracted features. The method combines existing methods to realize fast and memory-efficient factorization.
We introduce our prototype implementation of the proposed scheme, with which we demonstrate the effectiveness of the scheme by reviewing several past security incidents.
