In this paper, we propose a Bayesian change-point detection model for categorical data based on Dirichlet-multinomial mixtures. Because of the introduction of prior information, our method performs well for the
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...
