## 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. |

|
The audio data in the audios folder corresponds one-to-one with the human motion data in the gestures folder. |
