Test-Time Scaling in Reasoning LLMs: Inference Regimes, Evaluation, and Reproducibility

Mohsen Hariri, Weicong Chen, Nahal Shahini +11

Large language models can solve substantially harder reasoning problems with more inference-time compute. The term "test-time scaling," however, now covers diverse inference algori…

CausalGuard: Conformal Inference under Graph Uncertainty

Vikash Singh, Weicong Chen, Debargha Ganguly +12

Estimating treatment effects from observational data requires choosing an adjustment set, but valid adjustment depends on an unknown causal graph. Graph misspecification can cause…

Reliability-Gated Source Anchoring for Continual Test-Time Adaptation

Vikash Singh, Debargha Ganguly, Weicong Chen +8

Continual test-time adaptation (CTTA) updates a pretrained model online on an unlabeled, non-stationary stream while anchoring it to a frozen source checkpoint. This anchor is usef…

Trust The Typical

Debargha Ganguly, Sreehari Sankar, Biyao Zhang +8

Current approaches to LLM safety fundamentally rely on a brittle cat-and-mouse game of identifying and blocking known threats via guardrails. We argue for a fresh approach: robust…

Efficient Fine-Grained GPU Performance Modeling for Distributed Deep Learning of LLM

Biyao Zhang, Mingkai Zheng, Debargha Ganguly +4

Training Large Language Models(LLMs) is one of the most compute-intensive tasks in high-performance computing. Predicting end-to-end training time for multi-billion parameter model…

Grammars of Formal Uncertainty: When to Trust LLMs in Automated Reasoning Tasks

Debargha Ganguly, Vikash Singh, Sreehari Sankar +7

Large language models (LLMs) show remarkable promise for democratizing automated reasoning by generating formal specifications. However, a fundamental tension exists: LLMs are prob…
