Cross-Modal and Hierarchical Modeling of Video and Text

The code repository for "Cross-Modal and Hierarchical Modeling of Video and Text" in PyTorch

Prerequisites

The following packages are required to run the scripts:

• PyTorch >= 0.4 and torchvision

• Package tensorboardX and NLTK

• Dataset: please download features (The feature is still uploading uploaded.) and put them into the folder data/anet_precomp and data/didemo_precomp

Model Evaluation

The learned model on ActivityNet and DiDeMo can be found in this link. You can run train.py with option --resume and --eval_only to evaluate a given model, with options similar to the training scripts as below.

For a model with Inception feature on ActivityNet dataset at "./runs/release/activitynet/ICEP/hse_tau5e-4/run1/checkpoint.pth.tar", it can be evaluated by:

$ python train.py anet_precomp --feat_name icep --img_dim 2048 --resume ./runs/release/activitynet/ICEP/hse_tau5e-4/run1/checkpoint.pth.tar --eval_only

For a model with C3D feature on ActivityNet dataset at "./runs/release/activitynet/C3D/hse_tau5e-4/run1/checkpoint.pth.tar", it can be evaluated by:

$ python train.py anet_precomp --feat_name c3d --img_dim 500 --resume ./runs/release/activitynet/C3D/hse_tau5e-4/run1/checkpoint.pth.tar --eval_only

We presume the input model is a GPU stored model.

Model Training

To reproduce our experiments with HSE, please use train.py and follow the instructions below. To train HSE with \tau=5e-4, please with

$ --reconstruct_loss --lowest_reconstruct_loss

For example, to train HSE with \tau=5e-4 on ActivityNet with C3D feature:

$ python train.py anet_precomp --feat_name c3d --img_dim 500 --low_level_loss --reconstruct_loss --lowest_reconstruct_loss --norm

To train HSE with \tau=5e-4 on ActivityNet with Inception feature (The feature is still being uploaded):

$ python train.py anet_precomp --feat_name icep --img_dim 2048 --low_level_loss --reconstruct_loss --lowest_reconstruct_loss --norm

To train HSE with \tau=5e-4 on Didemo with Inception feature:

$ python train.py didemo_precomp --feat_name icep --img_dim 2048 --low_level_loss --reconstruct_loss --lowest_reconstruct_loss --norm

To train HSE with \tau=0 on ActivityNet with C3D feature:

$ python train.py anet_precomp --feat_name c3d --img_dim 500 --low_level_loss --norm
