# TimeChat-7B-ActivityNet-VTune Model

## Model details

We trained [TimeChat](https://arxiv.org/abs/2312.02051) using VTune, a developed instruction-tuning method specifically designed to account for consistency. 

For the tuning, we utilized 10K training videos from ActivityNet-Captions with 205K automatically generated annotations.

## Evaluation
We evaluated the model on ActivtyNet-CON and ActivtyNet-Captions.

- ActivityNet-CON
| Metric          | Value       |
|-----------------|-------------|
| Ground          | 37.4        |
| R-Ground        | 28.3 (75.6) |
| S-Ground        | 10.6 (28.3) |
| H-Verify        | 19.6 (52.3) |
| C-Verify        | 19.5 (51.5) |

- ActivityNet-Captions
| Metric          | Value   |
|-----------------|---------|
| R@1 IoU=0.3     | 57.74   |
| R@1 IoU=0.5     | 41.05   |
| R@1 IoU=0.7     | 23.72   |
| mIoU            | 40.89   |
