This repository contains the code for building a system similar to the one from the work Video Description using Bidirectional Recurrent Neural Networks, presented at the International Conference of Artificial Neural Networks (ICANN'16). With this module, you can replicate our experiments and easily deploy new models. ABiViRNet is built upon our fork of Keras framework and tested for the Theano and Tensorflow backends.
- Attention model over the input sequence of frames
- Peeked decoder LSTM: The previously generated word is an input of the current LSTM timestep
- MLPs for initializing the LSTM hidden and memory state
- Beam search decoding
ABiViRNet requires the following libraries:
Assuming you have a dataset and features extracted from the video frames:
- Prepare data:
python data_engine/subsample_frames_features.py
python data_engine/generate_features_lists.py
python data_engine/generate_descriptions_lists.py
See data_engine/README.md for detailed information.
-
Prepare the inputs/outputs of your model in
data_engine/prepare_data.py -
Set a model configuration in
config.py -
Train!:
python main.py
