Interpretable Contextual Team-aware Item Recommendation: Application in Multiplayer Online Battle Arena Game

Open In Colab

See paper in arXiv

tir-model

We release the PyTorch code of the TTIR model.

Content

Prerequisites

The code is built with following libraries:

Dataset

The used dataset is available here.

Code

We develop this project using Google Colab. That's why you must have a Google Account and the dataset in a gDrive folder. Furthermore, you have to change these paths according to the location of the dataset.

train_path = '/content/gdrive/My Drive/Proyecto_RecSys/dataset/train_splits.pkl'
test_path = '/content/gdrive/My Drive/Proyecto_RecSys/dataset/test_splits.pkl'
champion_path = '/content/gdrive/My Drive/Proyecto_RecSys/dataset/champion_types.pkl'

And the comet parameters (api_key, project_name, workspace)

comet_logger = CometLogger(
    experiment_name=conf['exp_name'],
    api_key = 'YOUR_KEY',
    project_name="YOUR_PROJECT_NAME",
    workspace = 'YOUR_WORKSPACE'
)

Baselines

This work uses the proposed models in Data mining for item recommendation in MOBA games paper as baselines.

Results

This method outperforms the state of the art approaches and explains the result.
