Change-point detectionDirichlet-multinomial mixturesOnline strategyChange-point detection for categorical data has wide applications in many fields. Existing methods either are distribution-free, not utilizing categorical information sufficiently, or have limited performance when there exists "rare events" (...
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...
