I am currently a research scientist at the Facebook AI Research lab in Menlo Park CA. I previously worked at Google in the Brain team, and before that, I was a post-doctoral fellow in Machine Learning, University of Toronto. I worked in Geoffrey Hinton's lab for two wonderful years. I did my Ph.D. in Computer Science at New York University in Yann LeCun's group. I am originally from Padova in Italy, where I graduated in Electronics Engineering. I am interested in Machine Learning, Computer Vision and, more generally, Artificial Intelligence. I have worked on Unsupervised Learning algorithms using both probabilistic graphical models and energy-based models. I also used these algorithms to build hierarchical models, called deep networks. I applied these models to a variety of applications, such as visual object recognition, speech recognition, text document retrieval.
