| Description | The contribution deals with change point detection in a one-dimensional stochastic process when using sparse parameter estimation from an overparametrized model. A stochastic process with change in the mean is estimated using dictionary consisting of Heaviside functions. The basis pursuit algorithm is applied to get sparse parameter estimates. Impact of serial correlations on change point detection is studied by simulations. |
