My work is aimed at making computer systems that infer the causes
underlying data and use that knowledge to make good decisions. It has
yielded systems that analyze tables, graphs, text and images.
I do this by scaling probabilistic reasoning --- making probabilistic
models that are sufficiently rich and realistic to support reliable
inferences, and making inference, estimation and prediction efficient
through massive parallelism. To make rich, realistic models manageable
and fast inference possible, I have worked on universal probabilistic
programming languages, efficient universal inference engines, special purpose randomized algorithms for inference, estimation and prediction, the
computational complexity of inference, and (where necessary) natively
probabilistic hardware.
The scientific foundations of this work lie in artificial intelligence
and probabilistic computation. The long-term goal is to build
computing systems that make good guesses under uncertainty as
naturally as traditional computing systems do logic and arithmetic, to
use these systems to help explain the mind and brain, and to close the
efficiency gap between natural and artificial computation.
I do this work through Navia Systems, a company I co-founded, and MIT (chiefly
the Computer Science and Artificial
Intelligence Laboratory and the Brain and Cognitive Sciences
Department) where I received my PhD in
2009 and was advised by Professor Joshua
Tenenbaum.
