Abstract
We consider the problem of detecting the change in mean in a sequence of Gaussian vectors. We assume that the change happens only in some of the components of the vector. We construct a nonparametric testing procedure that is adaptive to the number of changing components. Under high-dimensional assumptions we obtain the detection boundary and show the rate optimality of the test.
