Layer Importance for Mathematical Reasoning is Forged in Pre-Training and Invariant after Post-Training
Aadim Nepal, Safal Shrestha, Anubhav Shrestha +4
Large language models improve at math after instruction tuning, reinforcement learning, or knowledge distillation. We ask whether these gains come from major changes in the transfo…

Reinforcement Learning vs. Distillation: Understanding Accuracy and Capability in LLM Reasoning
Minwu Kim, Anubhav Shrestha, Safal Shrestha +2
Recent studies have shown that reinforcement learning with verifiable rewards (RLVR) enhances overall accuracy (pass@1) but often fails to improve capability (pass@k) of LLMs in re…

Warm Up Before You Train: Unlocking General Reasoning in Resource-Constrained Settings
Safal Shrestha, Minwu Kim, Aadim Nepal +2
Designing effective reasoning-capable LLMs typically requires training using Reinforcement Learning with Verifiable Rewards (RLVR) or distillation with carefully curated Long Chain…
