While traditional wet-lab experiments for RPI detection are costly and time-consuming, Deep Learning (DL) methods provide an efficient computational alternative for RPI Prediction (RPIP). In particular, Graph Neural Networks (GNNs) are promising, as they naturally model RPI networks. However, existing GNN-based methods often rely on homogeneous graphs or predefined meta-paths, which limit their ability to handle data sparsity and to generalize to cold-start scenarios involving unknown molecules. To address these limitations, we propose Edge Generation-guided Relation-aware Learning (EGRL), a novel framework with several key components: implicit meta-path learning to capture relational semantics without handcrafted paths; a multi-relation-aware attention mechanism for adaptive fusion of interaction patterns; a graph generator that predicts potential (\"soft\") edges to support cold-start nodes; and a multi-feature fusion predictor for final interaction scoring. EGRL is jointly trained with a primary task loss and an auxiliary generator loss. Comprehensive evaluations on four benchmark datasets demonstrate that EGRL achieves competitive overall performance. More importantly, it exhibits superior generalization in cold-start settings, achieving an Area Under the Receiver Operating Characteristic curve (AUROC) of 0.867 and an Area Under the Precision-Recall curve (AUPR) of 0.861 on unknown molecules, corresponding to improvements of 8.6% in AUROC and 5.0% in AUPR over prior state-of-the-art methods. The code will be released soon.", "url": "https://wpnews.pro/news/egrl-edge-generation-guided-relation-aware-learning-for-rna-protein-interaction", "canonical_source": "https://www.machinebrief.com/news/egrl-edge-generation-guided-relation-aware-learning-for-rna-6ww2", "published_at": "2026-08-14 04:00:00+00:00", "updated_at": "2026-08-14 05:11:30.032082+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["EGRL", "Graph Neural Networks"], "alternates": {"html": "https://wpnews.pro/news/egrl-edge-generation-guided-relation-aware-learning-for-rna-protein-interaction", "markdown": "https://wpnews.pro/news/egrl-edge-generation-guided-relation-aware-learning-for-rna-protein-interaction.md", "text": "https://wpnews.pro/news/egrl-edge-generation-guided-relation-aware-learning-for-rna-protein-interaction.txt", "jsonld": "https://wpnews.pro/news/egrl-edge-generation-guided-relation-aware-learning-for-rna-protein-interaction.jsonld"}}
