Changepoint Detection指的是在时间序列或数据流中检测出突变点或变化点的问题。突变点可能表示系统状态、行为、规律发生了改变。Changepoint Detection 是许多领域都很重要的一个问题,如金融市场、传感器网络、机器故障检测等。 2.3 Bayesian Online Changepoint Detection算法介绍: Bayesian Online Changepoint Detection算法...
In this paper we report on an event-based stochastic architecture for the Adams/McKay Bayesian Online Change Point Detection algorithm (BOCPD) [1]. In the stochastic computational structures, probabilities are represented natively as stochastic events and computation is carried out directly with these...

This paper develops a new class of flexible minimum description length (MDL) procedures for multiple changepoint detection. Existing MDL approaches, which are penalized likelihoods, use data description length information principles to construct penalties that depend on both the number of changepoints ...
changepoint are independent and we derive an online algorithm for exact inference of the most recent changepoint. We compute the probability distribution of the length of the current ``run,'' or time since the last changepoint, using a simple message-passing algorithm. Our implementation is ...
