Webb11 dec. 2024 · Before closing this article, we should take a moment to appreciate how powerful Bayesian inference is. We get the change point with such high certainty using only observed data and some initial beliefs. Plus, we get the distributions of the data before and after the change point. These distributions can tell us much more than single … Webb15 okt. 2024 · Cheng and Zhang [29] detect changes using graph theory. Sun et al. [30] propose a novel, online graph-based, change-point detection algorithm to detect change of distribution in low- to high-dimensional data. Iwayama et al. [31] propose a new method for detecting dynamical changes using recurrence networks.

WebbChange point detection is the identification of abrupt changes in the generative parameters of sequential data. In application areas such as finance, online rather than offline detection of change points in time series is mostly required, due to their use in predictive tasks, possibly embedded in automatic trading systems.
