Bayesian Network Regularized Regressión for Crime Modeling

"We present a new methodology for functional network regression on node atributes using a Laplacian operator based on edge similarities as regularizer. We show how usual regularization penalties can be cast as prior distributions on regression coefficients under a Bayesian setup, and propose a computationally efficient EM fitting procedure. We discuss a specific application to modeling residential burglary in Boston using a hierarchical model with latent indicators for "hot zones" and a conditional zero-inflated negative binomial regression for crime rates".
