Installation

Dataset

Training

Training on the existing datasets

You can use python src/train.py --dataset {dataset_name} --model_type {model_name} to train a specific model on a dataset. Other hyperparameters can be found in the code. (If you share the server with others or you want to use the specific GPU(s), you may need to set CUDA_VISIBLE_DEVICES.)

For example, you can use python src/train.py --dataset book --model_type ComiRec-SA to train ComiRec-SA model on Book dataset.

When training a ComiRec-DR model, you should set --learning_rate 0.005.

Training on your own datasets

If you want to train models on your own dataset, you should prepare the following three(or four) files:

Common Issues

<details> <summary> The computation of NDCG score. </summary> <br/> I'm so sorry that the computation of NDCG score in the original version (now in `paper` branch) is not consistent with the definition in the paper, as mentioned in the issue #6. I have updated the computation of NDCG score in the `master` branch according to the correct definition. For reproducing the NDCG scores reported in the paper, please use the `paper` branch. By the way, I personally recommend to use the reported results of recall and hit rate only. </details>

If you have ANY difficulties to get things working in the above steps, feel free to open an issue. You can expect a reply within 24 hours.
