Andrew E. Gelfand

My primary focus is on inference and learning in graphical models. I am interested in developing methods to efficiently perform inference in probabilistic models containing deterministic relations (constraints) and in developing approximate inference methods that exploit problem structure. I am also interested in the development and application of Perceptron-style methods, such as herding, to learning problems in areas like computer vision and chemoinformatics.
