| # BToks MMEB-V2 | |
| This dataset repository contains Lance-format converted data used by the open-source reproduction code for **Bottleneck Tokens for Unified Multimodal Retrieval** (arXiv:2604.11095). | |
| ## Source | |
| Converted from MMEB-V2 evaluation sources, including [ziyjiang/MMEB_Test_Instruct](https://huggingface.co/datasets/ziyjiang/MMEB_Test_Instruct) and the public upstream datasets referenced by MMEB-V2.. This repository does not change upstream ownership, licensing, citation requirements, or usage restrictions. | |
| ## Format | |
| The data is stored as Lance tables for the BToks/VLM2Emb training and evaluation scripts. The Hugging Face Dataset Viewer is disabled because this repository is not stored as standard Parquet or JSON splits. | |
| ## Usage | |
| Use this repository ID in the corresponding dataset config: | |
| ```yaml | |
| dataset_name: siyrus/BToks-MMEB-V2 | |
| ``` | |
| See the public BToks code repository for the config schema, training presets, and evaluation commands: https://github.com/siryuson/BottleneckTokens | |
| ## License and Citation | |
| Users must follow the license, citation requirements, and usage restrictions of the upstream source dataset. | |
