• Files for IvCDS are stored in directory simulator/, including the ablation study.

• Files for baselines are stored in directory baselines/

• Directory data/ contains the processed KVRET dataset

• Python=3.8
• Pytorch
• Transformers=4.18.0

• Files for training, inference and ablation study are available in directory simulator/.

• run_clm.py is the file for training, while 0-train-gpt-2.sh is the running script.

• inference/0-infer-gpt2.sh is the script for inference.

• inference/eval.ipynb is a jupyter file for the evaluation after IvCDS's training&inference.

• Directory ablation/ includes all scripts for ablation study. We provide three example scripts, please check any of them.

• Files For baselines is under directory baselines/.

• We use T5-large as an example, where 0-train-ALL-t5-large.sh and 1-eval-ALL-t5-large.sh are the files for training and inference, respectively.

• The evaluation of baselines uses the exact same file as IvCDS, see inference/eval.ipynb.

• All baseline models in this paper are pretrained, and they can be found on HuggingFace Models.

1. Before running a bash script, please modify the paths in it to the paths of your own environment.
2. The training of IvCDS takes about two hours on a single RTX 3090.
3. Checkpoints for models in our paper are available in this link.
4. The paper is still under review and this repository is at an early stage. The instructions may still lack details, and we will update it in the future.
