The MIT Probabilistic Computing Project

We build probabilistic computing systems that exploit uncertain knowledge to learn from data, infer its probable causes, make calibrated predictions and choose effective actions. We also study the computational principles and building blocks needed to design, implement and analyze these systems, drawing on and contributing to an emerging integration of key ideas from probability theory and computer science. Our research includes work on machine learning and artificial intelligence fundamentals, as well as applications to modeling human cognition and to intelligent data analysis.

So far, this work has yielded new general-purpose probabilistic programming technology and intentionally stochastic (but still digital) hardware for real-time Bayesian inference. It has also yielded academic and commercial Bayesian database systems that automate the analysis of high-dimensional data tables.


The ProbComp Reading List serves as a shared basis of knowledge for the project.
