Perspective in A.I. Seminar Computational Probabilistic Models

Abstract:
Probabilistic graphical models (PGMs) are a rich staple of probabilistic AI centered around variable-level (in)dependencies. In this talk I present some recent work on probabilistic models that go beyond classical PGMs, and make a radically different choice of abstraction; one that is computational. Concretely, I will discuss two up-and-coming classes of models: probabilistic circuits and probabilistic programs. Probabilistic circuits represent distributions through the computation graph of probabilistic inference, as a type of neural network. They move beyond PGMs and other deep generative models by guaranteeing tractable inference for certain classes of queries, thereby enabling new solutions to some key problems in machine learning. Probabilistic programs represent distributions through higher-level primitives of computation: iteration, branching, and procedural abstraction. They move beyond PGMs by looking “inside” of the dependencies. Finally, I will illustrate how these two computational abstractions are themselves closely related, by showing how the Dice probabilistic programming language compiles probabilistic programs into probabilistic circuits for inference.
