A non-parametric conditional factor regression model for high-dimensional input and response

2 Jul 2013  ·  Ava Bargi, Richard Yi Da Xu, Massimo Piccardi ·

In this paper, we propose a non-parametric conditional factor regression (NCFR)model for domains with high-dimensional input and response. NCFR enhances linear regression in two ways: a) introducing low-dimensional latent factors leading to dimensionality reduction and b) integrating an Indian Buffet Process as a prior for the latent factors to derive unlimited sparse dimensions. Experimental results comparing NCRF to several alternatives give evidence to remarkable prediction performance.
