Reasoning Models Can be Accurately Pruned Via Chain-of-Thought Reconstruction

ICLR 2026poster

Reasoning language models such as DeepSeek-R1 produce long chain-of-thought traces during inference time which make them costly to deploy at scale. We show that using compression techniques such as neural network pruning produces greater performance loss than in typical language modeling tasks, and…

AlphaPO: Reward Shape Matters for LLM Alignment

ICML 2025poster

Reinforcement Learning with Human Feedback (RLHF) and its variants have made huge strides toward the effective alignment of large language models (LLMs) to follow instructions and reflect human values. More recently, Direct Alignment Algorithms (DAAs) have emerged in which the reward modeling stage…

LLM Query Scheduling with Prefix Reuse and Latency Constraints

NeurIPS 2025poster

The efficient deployment of large language models (LLMs) in online settings requires optimizing inference performance under stringent latency constraints, particularly the time-to-first-token (TTFT) and time-per-output-token (TPOT). This paper focuses on the query scheduling problem for LLM inferenc…

Detecting Interactions from Neural Networks via Topological Analysis

NeurIPS 2020poster

Detecting statistical interactions between input features is a crucial and challenging task. Recent advances demonstrate that it is possible to extract learned interactions from trained neural networks. It has also been observed that, in neural networks, any interacting features must follow a strong…
