ogbn-papers100m-sage

This repository contains the code to reproduce the performance of ogbn-papers100m-sage on ogbn-papers100M dataset. Hyperparameters are empirically tunned the validation set. All experiments were runned with a Tesla V100 with 16GB memory.

We made some modifications based on the original GraphSAGE:

1. skip connection: the each sage conv layer, the inputs will be added to the outputs with a linear projection.
2. inception-like structure: the hidden representations of different perceptive field are concatenated for classification.

Requirements

Dependencies with python 3.7.3:

torch==1.5.1
ogb==1.2.5
dgl-cu92==0.6.0

Usage

pip install -r requirements.txt
python train.py

Training log will be written into directory "./log/[version]-[timestamp]-seed[seed]"
