[Forum SIS] Seminario Prof. Luis Carvalho 24.4. ore 12.30

[Dip. Scienze Statistiche - Mi]

Il Dipartimento di Scienze Statistiche dell'Università Cattolica del Sacro Cuore ha organizzato un seminario, presentato dal Prof. Luis Carvalho, Boston University Arts & Sciences, dal titolo:


Bayesian Network Regularized Regression
for Crime Modeling



Martedì 24 Aprile dalle ore 12,30

in Aula G252



Università Cattolica del Sacro Cuore - Milano

Largo Gemelli, 1


Abstract:
We present a new methodology for functional network regression on node attributes 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. This is joint work with Liz Upton.
