TL;DR: In this paper, the authors performed a comprehensive time series segmentation study on the 36 Nikkei Japanese industry indices from 1 January 1996 to 11 June 2010, and found that the Japanese economy never fully recovered from the extended 1997-2003 crisis, and responded to the most recent global financial crisis in five stages.

TL;DR: The authors performed a comprehensive time series segmentation study on the 36 Nikkei Japanese industry indices from 1 January 1996 to 11 June 2010 from the temporal distributions of the clustered segments, and found that the Japanese economy never fully recovered from the extended 1997-2003 crisis, and responded to the most recent global financial crisis in five stages.

TL;DR: This paper describes a specific recursive scheme for time series segmentation based on the Jensen-Shannon divergence, and applies it on the high-frequency time series data of various US and Japanese financial market indices, where it found that the time series segments can be very naturally grouped into four to six classes.

TL;DR: With this classification of the time series segments, it is discovered that the US economy recovered completely in one year six months, whereas the Japanese economy recovered incompletely in two years three months from the 2000 Technology Bubble Crisis.

TL;DR: The authors summarizes the content of the 28 tutorials that have been given at The Web Conference 2023 and summarizes the contents of these 28 tutorials in terms of their content and content of their topics.
