Learning Hidden Markov Models for Regression using Path Aggregation
نویسندگان
چکیده
We consider the task of learning mappings from sequential data to real-valued responses. We present and evaluate an approach to learning a type of hidden Markov model (HMM) for regression. The learning process involves inferring the structure and parameters of a conventional HMM, while simultaneously learning a regression model that maps features that characterize paths through the model to continuous responses. Our results, in both synthetic and biological domains, demonstrate the value of jointly learning the two components of our approach.

Due to the effective role of Markov models in customer relationship management (CRM), there is a lack of comprehensive literature review which contains all related literatures. In this paper the focus is on academic databases to find all the articles that had been published in 2011 and earlier. One hundred articles were identified and reviewed to find direct relevance for applying Markov models...

Using Input-Output Hidden Markov Models for the Aggregation of Performance Models
This paper describes a new idea how to use InputOutput Hidden Markov Models (IOHMMs) for the aggregation of performance models and reports about corresponding first experiments. The parameters of the IOHMM are calculated from observation sequences obtained from the input/output behaviour of the original model.
متن کاملBridging Viterbi and posterior decoding: a generalized risk approach to hidden path inference based on hidden Markov models
Motivated by the unceasing interest in hidden Markov models (HMMs), this paper reexamines hidden path inference in these models, using primarily a risk-based framework. While the most common maximum a posteriori (MAP), or Viterbi, path estimator and the minimum error, or Posterior Decoder (PD) have long been around, other path estimators, or decoders, have been either only hinted at or applied ...
