This repository includes the codebase for adapting EgoVLP features to NLQ & MQ, Ego4D challenges.

NLQ (VSLNet)

• Extract video features python3 run/test_nlq.py --subsample 'video'

  • We have uploaded EgoVLP clip-level features on G Drive, you can download them directly and do not need to extract them by yourself.
    • train & val clip features: https://drive.google.com/file/d/1TXBlLDqDuL_XPCuXlgiikEfVXO8Ly6eM/view
    • test video features: https://drive.google.com/file/d/1-CGZg9t-kpW5bmg9M62VHk5eYTllsPKV/view

• For the text branch, I recommend directly loading the pretrained text encoder, first download the egovlp checkpoints: https://drive.google.com/file/d/1-cP3Gcg0NGDcMZalgJ_615BQdbFIbcj7/view

• Set up VSLNet codebase.

  • Install environment dependency: pip install environment.txt
  • The metadata has been included in the codebase.
  • Place the downloaded pertained checkpoint to the VSLNet/utils/frozen_ego_minimum/pretrained
  • Run the training script: bash VSLNet/scripts/03_egovlp_egonce.sh
  • You can monitor the training log in the such path: VSLNet/checkpoints/egovlp_egonce_default/egovlp_egonce_batch32/vslnet_nlq_official_v1_egovlp_egonce_256_EgoVLP/model/eval_results.txt

• Model configs / training log / fine-tuned checkpoints

  • default setting: VSLNet/checkpoints/egovlp_egonce_default

  • the best setting, w/ hyper-parameters searching (bs, LR, max_pos_len): VSLNet/checkpoints/hps_search_egovlp_egonce

    • # how we perform hps
      EXP_NUMBER = 0
      
      for BSIZE in [4, 8, 16, 32, 128, 512]:
          for LR_RATE in [0.0005,0.0001,0.00005,0.00001]:
              for MAXPOSLEN in [64,128,256,512]:
                  create_sbatches(EXP_NUMBER, BSIZE, LR_RATE, MAXPOSLEN)
                  EXP_NUMBER+=1
                              
      print(f'Total Number of experiments {EXP_NUMBER}.')

• Experimental results:

VSLNet	SlowFast + BERT	5.45	10.74	3.12	6.63

MQ (VSGN)

• Extract video features python3 run/test_mq.py --subsample 'video'

  • We have uploaded EgoVLP clip-level features on G Drive, you can download them directly and do not need to extract them by yourself.
