Introduction

Multi-modal Graph Convolution Network is a novel multi-modal recommendation framework based on graph convolutional networks, explicitly modeling modal-specific user preferences to enhance micro-video recommendation. We update the code and use the full-ranking strategy for validation and testing.

Environment Requirement

The code has been tested running under Python 3.5.2. The required packages are as follows:

• Pytorch == 1.1.0
• torch-cluster == 1.4.2
• torch-geometric == 1.2.1
• torch-scatter == 1.2.0
• torch-sparse == 0.4.0
• numpy == 1.16.0

Example to Run the Codes

The instruction of commands has been clearly stated in the codes.

• Kwai dataset
  python main.py --model_name='MMGCN' --l_r=0.0005 --weight_decay=0.1 --batch_size=1024 --dim_latent=64 --num_workers=30 --aggr_mode='mean' --num_layer=2 --concat=False
• Tiktok dataset
  python main.py --model_name='MMGCN' --l_r=0.0005 --weight_decay=0.1 --batch_size=1024 --dim_latent=64 --num_workers=30 --aggr_mode='mean' --num_layer=2 --concat=False
• Movielens dataset
  python main.py --model_name='MMGCN' --l_r=0.0001 --weight_decay=0.0001 --batch_size=1024 --dim_latent=64 --num_workers=30 --aggr_mode='mean' --num_layer=2 --concat=False

Some important arguments:

• model_name: It specifies the type of model. Here we provide three options:

  1. MMGCN (by default) proposed in MMGCN: Multi-modal Graph Convolution Network for Personalized Recommendation of Micro-video, ACM MM2019. Usage: --model_name='MMGCN'
  2. VBPR proposed in VBPR: Visual Bayesian Personalized Ranking from Implicit Feedback, AAAI2016. Usage: --model_name 'VBPR'
  3. ACF proposed in Attentive Collaborative Filtering: Multimedia Recommendation with Item- and Component-Level Attention , SIGIR2017. Usage: --model_name 'ACF'
  4. GraphSAGE proposed in Inductive Representation Learning on Large Graphs, NIPS2017. Usage: --model_name 'GraphSAGE'
  5. NGCF proposed in Neural Graph Collaborative Filtering, SIGIR2019. Usage: --model_name 'NGCF'

• aggr_mode It specifics the type of aggregation layer. Here we provide three options:

  1. mean (by default) implements the mean aggregation in aggregation layer. Usage --aggr_mode 'mean'
  2. max implements the max aggregation in aggregation layer. Usage --aggr_mode 'max'
  3. add implements the sum aggregation in aggregation layer. Usage --aggr_mode 'add'

• concat: It indicates the type of combination layer. Here we provide two options:

  1. concat(by default) implements the concatenation combination in combination layer. Usage --concat 'True'
  2. ele implements the element-wise combination in combination layer. Usage --concat 'False'

Dataset

We provide three processed datasets: Kwai, Tiktok, and Movielnes.

• You can find the full version of recommendation datasets via Kwai, Tiktok, and Movielens. Since the copyright of datasets, we cannot release them directly. To facilate the line of research, we provide some toy datasets[BaiduPan](code: zsye) or [GoogleDriven]. Anyone needs the full datasets, please contact the owner of datasets.
