(A) Average log-likelihood of the frames from the i + 1st window under the ith model. Sudden drops in likelihood mark the transition between sub-states. (B) Log-likelihoods for each frame under each of the 500 models. (C) The first 50 rows and first 2,000 columns of the matrix from panel B. The block-structure illustrates the sub-states visited in the first 2,000 frames.
