TimeChat-7B-ActivityNet-VTune Model

Model details

We trained TimeChat 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
