Auditing Preference Biases and Fine-Tuning Language Models with Direct Preference Optimization on Anthropic HH-RLHF Using TRL and LoRA
MarkTechPost Sana Hassan
The tutorial builds an end-to-end preference-learning workflow that fine-tunes a language model with Direct Preference Optimization (DPO) on the Anthropic HH-RLHF dataset while auditing for structural and length-based preference biases and testing for lexical shortcut signals.
Why it matters
This tutorial provides an end-to-end workflow for fine-tuning language models using Direct Preference Optimization (DPO). We demonstrate how to audit the Anthropic HH-RLHF dataset for structural and length-based biases, implement a robust training pipeline using TRL and LoRA, and evaluate model performance to ensure genuine preference learning rather than reliance on lexical shortcuts.
