Overview

Label-Exploring Graph Neural Network (LEX-GNN) is a GNN-based fraud detector that predicts the fraud likelihood of nodes in a semi-supervised manner and adaptively adjusts the message passing pipeline for enhanced detection.

Usage

• Dataset: Yelp and Amazon are loaded from dgl.data.fraud when the code executed.
• Run: python main.py
