Fitting a deeply-nested hierarchical model to a large book review dataset using a moment-based estimator

no code implementations1 Jun 2018 Ningshan Zhang, Kyle Schmaus, Patrick O. Perry

The main challenge in deploying this model is computational: the data sizes are large, and fitting the model at scale using off-the-shelf maximum likelihood procedures is prohibitive.

Regularized Laplacian Estimation and Fast Eigenvector Approximation

no code implementations NeurIPS 2011 Patrick O. Perry, Michael W. Mahoney

Conversely, it will imply that the solution to this regularized estimation problem can be computed very quickly by running, e. g., the fast diffusion-based PageRank procedure for computing an approximation to the first nontrivial eigenvector of the graph Laplacian.
