Matrix and Tensor Estimation in Action
Matrix and Tensor Estimation in Action


In this workshop, we will provide an overview of techniques for matrix and tensor estimation. We will showcase a wide variety of applications for matrix estimation in analyzing large heterogeneous datasets that may have missing or incorrect entries, including retail, causal inference, sports and networks. These applications will form the basis for some practical demos with opportunities for hands-on experience. Subsequently we will explain the intuition for matrix and tensor estimation algorithms, with a focus on collaborative filtering.
