Abstract

fetched live from OpenAlex

Converging evidence from the behavioral sciences suggests that inference in probabilistic generative models can capture how human and animal subjects solve a variety of cognitive tasks involving uncertainty. In fact, such evidence has accumulated more quickly than bespoke computational modeling can keep pace, contributing impetus to the development of probabilistic programming systems to reduce the duplication of effort. Among these, deep probabilistic programming systems enable the integration of deep neural networks into probabilistic generative models as powerful function approximators. In this dissertation, I provide compositional tools for reasoning about model structure and inference in the deep probabilistic programming system Probabilistic Torch. I begin with a case report about applying deep probabilistic programming to neuroimaging, including mean-field inference and a nontrivial stochastic gradient estimator for the training objective. I then dive into my work on training neural proposals to break down a complex joint distribution into a series of simpler complete conditional distributions. I then describe my contributions to a domain-specific language of inference combinators for composing importance sampling strategies in deep probabilistic programs, including an inference combinators implementation of the previous decompositional sampling strategy. I finally overview my work on providing categorical foundations in which to ground the semantics of deep probabilistic programs and reason compositionally about their model structure and inference strategies. I then close the dissertation by discussing how compositionality can help probabilistic machine learning scale up towards brain-sized inference problems.--Author's abstract

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
