Large-scale Collaborative Filtering with Product Embeddings
Thom Lake, Sinead A. Williamson, Alexander T. Hawk +2
The application of machine learning techniques to large-scale personalized recommendation problems is a challenging task. Such systems must make sense of enormous amounts of implic…
High-dimensional Sparse Inverse Covariance Estimation using Greedy Methods
Christopher C. Johnson, Ali Jalali, Pradeep Ravikumar
In this paper we consider the task of estimating the non-zero pattern of the sparse inverse covariance matrix of a zero-mean Gaussian random vector from a set of iid samples. Note…
On Learning Discrete Graphical Models Using Greedy Methods
Ali Jalali, Chris Johnson, Pradeep Ravikumar
In this paper, we address the problem of learning the structure of a pairwise graphical model from samples in a high-dimensional setting. Our first main result studies the sparsist…
