Improving Attributed Text Generation of Large Language Models via Preference Learning

Overview

Automatic Preference Optimization(APO) framework includes an automatic preference construction procedure and a fine-grained preference optimization procedure, which is used to handle attributed text generation tasks.

Dataset

The dataset is available here.

Environment

conda create -n attri_trl python=3.10
conda activate attri_trl
pip install -r requirements.txt

Step1: Post-training

Using data from post_training.

The training scripts is provided in post_training/scripts.

finetune.sh is used to train base model.

finetune_ablation.sh is used to perform continue post-training after the post-training precedure having finished (ablation study).

Step2: Perference Optimization

Using data from preference_optimization.jsonl

The training scripts is provided in po/scripts.

Step3: Evaluation

We use the ALCE official evaluation scripts alongwith custom prompts. The evaluation scripts can be found in evaluation_alce.
