Change-Point Detection in Time-Series Data by Direct Density
... A common limitation of the above-mentioned approaches is that they rely on pre-specified parametric models such as probability density models, autoregressive models, and state-space models. Thus, these methods tend to be less flexible in real-world change-point detection scenarios. The primal purpos ...

Expectation–maximization algorithm
In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
