Overview

VidLanKD

Implementation of VidLanKD: Improving Language Understanding via Video-Distilled Knowledge Transfer by Zineng Tang, Jaemin Cho, Hao Tan, Mohit Bansal.

Setup

# Create python environment (optional)
conda create -n vidlankd python=3.7

# Install python dependencies
pip install -r requirements.txt

To speed up the training, we use mixed precision with Apex.

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

Dataset Preparation

Text Dataset

We provide scripts to obtain datasets "wiki103" and "wiki".

Wiki103, a seleted subset of English Wikipedia.

bash data/wiki103/get_data_cased.bash

English Wikipedia. The scripts are modified from XLM.

bash data/wiki/get_data_cased.bash en

Video Dataset

Howto100m where you can download official captions and videos features.

Video Features Extraction Code

To be updated.

  • We extracted our 2D-level video features with ResNet152 from torchvision.
  • We extracted our 3D-level video features with 3D-RexNext.

Downstream tasks

GLUE dataset
