Introduction

Dynamic Graph Evolution Learning (DGEL) aims to solve the graph-based real-time evolution problem for multi-round recommendation scenario by three efficient learning modules and also bridge the normalization with model learning by re-scaling enhancement network for better capturing the dynamics.

Run the codes

Take the Wikipedia dataset as example. Run the following commands:

CUDA_VISIBLE_DEVICES=0 python main.py --dataset wikipedia --embedding_dim 32 --sample_length 100 --epochs 30
CUDA_VISIBLE_DEVICES=0 python evaluate_all.py --dataset wikipedia --embedding_dim 32 --sample_length 100 --epochs 30

--dataset: indicating the data name you select <br>--embedding_dim: diminsion of each dynamic sub-embedding <br>--sample_length: the number of neighbors <br>--epochs: the number of training epochs
