Steiner Tree Approximation - June 15

In this lecture we will summarize our recent work on Steiner tree approximation together with J. Byrka, T. Rothvoß and L. Sanità. Part of the results appeared in “An Improved LP-based Approximation for Steiner Tree” (STOC’10), and some other results are contained in the journal version of the paper, currently under revision. We will not be very formal, and we will abuse notation. We apologize f...

Adaptive Ridge Selector ( ARiS ) June 15 , 2008

We introduce a new shrinkage variable selection operator for linear models which we term the adaptive ridge selector (ARiS). This approach is inspired by the relevance vector machine (RVM), which uses a Bayesian hierarchical linear setup to do variable selection and model estimation. Extending the RVM algorithm, we include a proper prior distribution for the precisions of the regression coeffic...
