QUIC & DIRTY: A Quadratic Approximation Approach for Dirty Statistical Models

no code implementations NeurIPS 2014 Cho-Jui Hsieh, Inderjit S. Dhillon, Pradeep K. Ravikumar, Stephen Becker, Peder A. Olsen

In this paper, we develop a family of algorithms for optimizing superposition-structured” or “dirty” statistical estimators for high-dimensional problems involving the minimization of the sum of a smooth loss function with a hybrid regularization.

Newton-Like Methods for Sparse Inverse Covariance Estimation

no code implementations NeurIPS 2012 Figen Oztoprak, Jorge Nocedal, Steven Rennie, Peder A. Olsen

The second approach, which we call the Orthant-Based Newton method, is a two-phase algorithm that first identifies an orthant face and then minimizes a smooth quadratic approximation of the objective function using the conjugate gradient method.
