reconstruction-network-for-video-captioning

This project tries to implement RecNet proposed on Reconstruction Network for Video Captioning in CVPR 2018.

Requirements

• Ubuntu 16.04
• CUDA 9.0
• cuDNN 7.3.1
• Java 1.8
• Python 2.7.12
  • PyTorch 1.0
  • Other python libraries specified in requirements.txt

How to use

Step 1. Setup python virtual environment

$ pip install virtualenv
$ virtualenv .env
$ source .env/bin/activate
(.env) $ pip install --upgrade pip
(.env) $ pip install -r requirements.txt

Step 2. Prepare Data

1. Extract feature vectors of datasets (e.g. MSVD), and locate them at ~/<dataset>/features/<network>.hdf5

   e.g. InceptionV4 feature vectors of MSVD dataset will be located at ~/data/MSVD/features/InceptionV4.hdf5.

2. Set hyperparameters in config.py and split the dataset into train / val / test dataset by running following command.

   (.env) $ python -m scripts.split
   

Step 3. Train

1. Set hyperparameters in config.py.
2. Run

   (.env) $ python train.py
   

Step 4. Inference

1. Set hyperparameters in config.py.
2. Run

   (.env) $ python run.py
   

Result

Comparison with original paper

NOTE: For now, only 2D features are used for evaluating our model (3D features are missing).
