Breaking the Tokenizer Barrier: On-Policy Distillation across Model Families

Yifan Niu, Han Xiao, Dongyi Liu +4

On-Policy Distillation (OPD) has become a core technique in the post-training of Large Language Models (LLMs) for transferring knowledge from domain experts to student models. Howe…

AVSD: Adaptive-View Self-Distillation by Balancing Consensus and Teacher-Specific Privileged Signals

Duy Nguyen, Hanqi Xiao, Archiki Prasad +7

Self-distillation enables language models to learn on-policy from their own trajectories by using the same model as both student and teacher, with the teacher being conditioned on…

Playing Along: Learning a Double-Agent Defender for Belief Steering via Theory of Mind

Hanqi Xiao, Vaidehi Patil, Zaid Khan +3

As large language models (LLMs) become the engine behind conversational systems, their ability to reason about the intentions and states of their dialogue partners (i.e., form and…

Skill-SD: Skill-Conditioned Self-Distillation for Multi-turn LLM Agents

Hao Wang, Guozhi Wang, Han Xiao +8

Reinforcement learning (RL) has been widely used to train LLM agents for multi-turn interactive tasks, but its sample efficiency is severely limited by sparse rewards and long hori…

Conflict-Resolving and Sharpness-Aware Minimization for Generalized Knowledge Editing with Multiple Updates

Duy Nguyen, Hanqi Xiao, Archiki Prasad +3

Large language models (LLMs) rely on internal knowledge to solve many downstream tasks, making it crucial to keep them up to date. Since full retraining is expensive, prior work ha…

Generalized Correctness Models: Learning Calibrated and Model-Agnostic Correctness Predictors from Historical Patterns

Hanqi Xiao, Vaidehi Patil, Hyunji Lee +2

Generating accurate and calibrated confidence estimates is critical for deploying LLMs in high-stakes or user-facing applications, and remains an open challenge. Prior research has…
