This model is based upon the latest research in deep . 1. The following snippet creates a noisy piecewise constant signal, performs a penalized kernel change point detection and displays the results (alternating colors mark true regimes and dashed lines mark estimated change points). Orange cells indicate good matches with the true dataset. It is a sequential approach: first, one change point is detected in the complete input signal, then series is split around this change point, then the operation is repeated on the two resulting sub-signals. Example Usage The tool can detect changes in the mean value, standard deviation, or linear trend of continuous variables as well as changes in the mean of count variables. Example: Let's say a column of data consists of the income of citizens per month and that column contains the salary of Bill Gates as well. The initial state is also chosen uniformly at random, so we have: z 1 Categorical ( { 1 4, 1 4, 1 4, 1 4 }) z t | z t 1 Categorical ( { p if z t = z t 1 1 p 4 1 otherwise }) These assumptions correspond to a hidden Markov model with Poisson emissions.
