A reference implemententation of the CoSeRNN model for contextual music
recommendation, presented in the following paper:

> Casper Hansen, Christian Hansen, Lucas Maystre, Rishabh Mehrotra, Brian
> Brost, Federico Tomasi, Mounia Lalmas. _[Contextual and Sequential User
> Embeddings for Large-Scale Music
> Recommendation](https://dl.acm.org/doi/10.1145/3383313.3412248)_, RecSys
> 2020.

## Getting Started

Our implementation requires Python 3.7 and TensorFlow 1.x. To run the code, you
will need a CUDA-enabled GPU.

- Move to the repository with: `cd cosernn`
- install the dependencies: `pip install -r requirements.txt`
- install the package: `pip install -e lib/`

Generate data using

python scripts/generate_data.py

Train the CoSeRNN model using

python scripts/train.py path/to/records
