Thema

Naturalness & Bimodality of Code

Sprache: English

Abstract

After discovering, back in 2011, that Language Models are useful for modeling repetitive patterns in source code (c.f. The “Naturalness” of software), and exploring some applications thereof, more recently (since about 2019) our group at UC Davis has focused on the observation that Software, as usually written, is bimodal, admitting both the well-known formal, deterministic semantics (mostly for machines) and probabilistic, noisy semantics (for humans). This bimodality property affords both new approaches to software tool construction (using machine-learning) and new ways of studying human code reading. In this talk, I'll give an overview of the Naturalness/Bimodality program, and some recent work we have done on the quality of code produced by large language models, and also on “bimodal prompting”.

Bio

Prem Devanbu holds a B.Tech from IIT Madras, and a Ph.D from Rutgers University. After circa 20 years at Bell Labs, he joined UC Davis, where he is now a Distinguished Professor Emeritus (Recalled as Research Professor) of Computer Science. He works in Empirical Software Engineering, and AI for SE, specifically exploiting "big data" available in software repositories to support software development. He is a winner of the ACM SIGSOFT Outstanding Research Award (2021), and the Alexander von Humboldt Research Award (2022), and several best-paper, most-influential paper, and test-of-time awards. He is a Fellow of the ACM.
