WebAbstract: Hidden Markov models (HMMs) are one of the most widely used unsupervised-learning algorithms for modeling discrete sequential data. Traditionally, most of the applications of HMMs have utilized only models of order 1 because higher-order models are computationally hard to train. WebAbstract—Hidden Markov models (HMMs) are a popular approach for modeling sequential data, typically based on the assumption of a ﬁrst- or moderate-order Markov chain. However, in many real-world scenarios the modeled data entail temporal dynamics the patterns of which change over time. china natural resources
