Simplifying Flow Matching Transformations with Low-Rank Mixture Models

Liam A. Kruse, Houjun Liu, Alexandros E. Tzikas +2

Normalizing flows are powerful generative models that learn an invertible mapping between complex data distributions and simple latent distributions, typically a standard normal de…

SecureForge: Finding and Preventing Vulnerabilities in LLM-Generated Code via Prompt Optimization

Houjun Liu, Lisa Einstein, John Yang +5

LLM coding agents now generate code at an unprecedented scale, yet LLM-generated code introduces cybersecurity vulnerabilities into codebases without human involvement. Even when f…

Thoughtbubbles: an Unsupervised Method for Parallel Thinking in Latent Space

Houjun Liu, Shikhar Murty, Christopher D. Manning +1

Current approaches for scaling inference-time compute in transformers train them to emit explicit chain-of-thought tokens before producing an answer. While these methods are powerf…
