| ## Dataset description |
| - The Streamer dataset we proposed consists of 281 anchors and 20,969 clips of data. |
| - The training set contains 19,051 clips of data and 269 anchors. |
| - The seen test set contains 920 clips of data, where the anchor ID has appeared in the training set. |
| - The unseen test set contains 998 clips of data, where the anchor ID has never appeared in the training set. |
|
|
| ## Dataset structure |
| The dataset contains three folders: *train*, *test_seen*, and *test_unseen*. Let's *train* train as an example for introduction. |
|
|
| ```plaintext |
| -train/ |
| ├── audios/ |
| │ ├── {anchor_id}/ |
| │ │ └── {video_name_md5}/ |
| │ │ └── {start_time}_{end_time}.wav |
| ├── gestures/ |
| │ ├── {anchor_id}/ |
| │ │ └── {video_name_md5}/ |
| │ │ └── {start_time}_{end_time}.pkl |
| ``` |
| The audio data in the audios folder corresponds one-to-one with the human motion data in the gestures folder. |
|
|
| For the Hugging Face Dataset Viewer, this repository also includes lightweight |
| CSV manifests under `viewer/`. They index each clip in the zip archives so the |
| viewer can render a table without scanning the full raw payload. |
