PAC Prediction Sets for Large Language Models of Code

1 code implementation17 Feb 2023 Adam Khakhar, Stephen Mell, Osbert Bastani

Given a trained code generation model, our algorithm leverages a programming language's abstract syntax tree to generate a set of programs such that the correct program is in the set with high-confidence.

Counterfactual Explanations for Natural Language Interfaces

1 code implementation ACL 2022 George Tolkachev, Stephen Mell, Steve Zdancewic, Osbert Bastani

A key challenge facing natural language interfaces is enabling users to understand the capabilities of the underlying system.

Synthesizing Video Trajectory Queries

no code implementations NeurIPS Workshop AIPLANS 2021 Stephen Mell, Favyen Bastani, Stephan Zdancewic, Osbert Bastani

A key challenge is that queries are difficult for end users to develop: queries must reason about complex spatial and temporal patterns in object trajectories in order to select trajectories of interest, and predicates often include real-valued parameters (e. g., whether two cars are within a certain distance) that can be tedious to manually tune.

Safe Predictors for Enforcing Input-Output Specifications

no code implementations29 Jan 2020 Stephen Mell, Olivia Brown, Justin Goodwin, Sung-Hyun Son

We present an approach for designing correct-by-construction neural networks (and other machine learning models) that are guaranteed to be consistent with a collection of input-output specifications before, during, and after algorithm training.
