| # CorVer-infini-gram-index | |
| This repository contains the prebuilt Wikipedia infini-gram index (tokenized with Llama-2) used for **CorVer** (*Corpus Verify*), a lightweight process reward for reinforcement learning fine-tuning on factual question answering. | |
| The dataset was introduced in the paper [Verifiable Rewards Beyond Math and Code: Lightweight Corpus-Grounded Process Supervision for Factual Question Answering](https://huggingface.co/papers/2605.29648). | |
| - **GitHub Repository**: [https://github.com/shichengf/CorVer](https://github.com/shichengf/CorVer) | |

| ## Sample Usage | |
| You can download the index using the `huggingface-cli`: | |
| ```bash | |
| huggingface-cli download Shichengf/CorVer-infini-gram-index \ | |
| --repo-type dataset --local-dir ./infigram_index | |
| export INFIGRAM_LOCAL_INDEX_DIR=./infigram_index | |
