Weibull partition models with applications to hidden semi-Markov models
2017 International Joint Conference on Neural Networks (IJCNN), 2017We develop the Weibull partition model (WPM), which defines a novel nonparametric stochastic process over distributions of partitions of sequential data, aiming at directly modeling the boundaries of segments comprising the sequence. The Weibull partition model employs a Dirichlet process mixture with a Weibull kernel.

Using Hidden Semi-Markov Model for learning behavior in smarthomes
2015 IEEE International Conference on Automation Science and Engineering (CASE), 2015Within the framework of demographic changes and the constraint of permanent growth of the elderly number in European population (i.e. France) which the health sector is confronted to, the detection of abnormal behaviors in the supervisory framework has known a particular interest during these last years.

Reliability modeling with hidden Markov and semi-Markov chains
2013 IEEE Integration of Stochastic Energy in Power Systems Workshop (ISEPS), 2013Abstract form only given. Semi-Markov processes and Markov renewal processes represent a class of stochastic processes that generalize Markov and renewal processes. As it is well known, for a discrete-time (respectively continuous-time) Markov process, the sojourn time in each state is geometrically (respectively exponentially) distributed. In the semi-

Online identification of hidden Semi-Markov models
3rd International Symposium on Image and Signal Processing and Analysis, 2003. ISPA 2003. Proceedings of the, 2004Hidden Markov models (HMM) are a powerful tool in signal modelling. In an HMM, the probability that signal leaves a state is constant, and hence the duration that signal stays in each state has an exponential distribution. However, this exponential density is not appropriate for a large class of physical signals.
