ToolFlow: Boosting LLM Tool-Calling Through Natural and Coherent Dialogue Synthesis

Zezhong Wang, Xingshan Zeng, Weiwen Liu +6

Supervised fine-tuning (SFT) is a common method to enhance the tool calling capabilities of Large Language Models (LLMs), with the training data often being synthesized. The curren…

Chain-of-Probe: Examining the Necessity and Accuracy of CoT Step-by-Step

Zezhong Wang, Xingshan Zeng, Weiwen Liu +7

Current research found the issue of Early Answering in large language models (LLMs), where the models already have an answer before generating the Chain-of-Thought (CoT). This phen…

DAST: Difficulty-Aware Self-Training on Large Language Models

Boyang Xue, Qi Zhu, Hongru Wang +8

Present Large Language Models (LLM) self-training methods always under-sample on challenging queries, leading to inadequate learning on difficult problems which limits LLMs' abilit…
