Parameters : n_components : int Number of states. _covariance_type : string String describing the type of covariance parameters to use. Must be one of ‘spherical’, ‘tied’, ‘diag’, ‘full’. Defaults to ‘diag’. See also GMM self-consistency model

To visualize this process, let’s first consider the XOR dataset ( Table 1, left ). WebAug 18, 2024 · The Viterbi algorithm is a dynamic programming algorithm similar to the forward procedure which is often used to find maximum likelihood. Instead of tracking the total probability of generating the observations, it tracks the maximum probability and the corresponding state sequence. self-consistency bias
