Simplified Noise Injection vs. Heavy Augmentation in Graph Contrastive Learning for Sparse Recommendations

This report synthesises findings from 7 peer-reviewed papers addressing the following research question: How does the performance of simplified noise injection in graph contrastive learning compare to heavy augmentation techniques in terms of mean average precision (MAP) on extreme sparse recommendation. Abstract Data scarcity is a major challenge when training deep learning (DL) models. DL demands a large amount of data to achieve exceptional performance. 12 claims were extracted from source literature; 10 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 7.5/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research goal: How does the performance of simplified noise injection in graph contrastive learning compare to heavy augmentation techniques in terms of mean average precision (MAP) on extreme sparse recommendation datasets like ogbn-products?
