Draw any probability distribution that sums close to 1 and gets as close as possible to the target KL divergence number\. You have 10 seconds to do it\. Go\! **KL 0\.1** nearly same **KL 1** shifted shape **KL 10** far apart

Entropy-KL Divergence-based Token Masking: A Novel Approach for Selective Fine-tuning of Large Language Models

arXiv cs.AI

Proposes EKSFT, a selective fine-tuning method for large language models that masks tokens with high entropy or high KL divergence from a reference model, preserving pre-trained distribution while injecting task knowledge. Experiments on mathematical reasoning benchmarks show it outperforms standard SFT and improves subsequent RL fine-tuning.
