Abstract:
|
We will survey recent work from the computer science community on the problem of estimating multivariate log-concave densities. Specifically, we will give an overview of the following contributions: (1) We will describe an estimator that yielded the first known finite sample upper bound for the problem. (2) We will sketch an analysis that gave the first finite sample complexity bound for the multivariate log-concave MLE in d>3 dimensions. (3) We will describe the first algorithm to compute the multivariate log-concave MLE in sample polynomial time.
