An application of MCMC methods for the multiple change-points problem

Abstract: We present in this paper a multiple change-point analysis for which an MCMC sampler plays a fundamental role. It is used for estimating the posterior distribution of the unknown sequence of change-points instants, and also for estimating the hyperparameters of the model. Furthermore, a slight modi"cation of the algorithm allows one to compute the change-points sequences of highest probabilities. The so-called reversible jump algorithm is not necessary in this framework, and a very much simpler and faster proce… Show more

“…Univariate algorithms for estimating the transition times for sensory data with piecewise constant changes in the variance are broadly separated into two categories: namely i) algorithms based on statistical significance tests [2] and ii) Bayesian methods, that is, identifying a posterior distribution and obtaining the corresponding maximum a posteriori (MAP) estimates of the change point locations and other parameters of interest [3] [4]. These techniques have found a wide range of applications in the segmentation of time series data, however, a need had arisen for the development of multi-sensor extensions of such algorithms for more accurate segmentation.…”
