Accurate Graph-based Multi-Positive Unlabeled Learning via Disentangled Multi-view Feature Propagation
Explore how D-MVP leverages disentangled multi-view feature propagation for superior graph-based MPU learning, enhancing accuracy and interpretability in complex data environments.
Executive Impact & Key Metrics
This research introduces D-MVP, a novel method for graph-based MPU learning. It addresses challenges like over-smoothing and lack of common features in existing approaches by disentangling feature propagation into multiple views. D-MVP uses distinct weights for each view, aggregates information differently, and captures both shared and distinctive features among positive classes. Experiments show D-MVP consistently outperforms baselines, offering improved accuracy and interpretability in classifying graph-structured data with limited labels.

Disentangled Propagation
D-MVP addresses the challenge of distinguishing between shared and distinctive features in positive classes by disentangling feature propagation into multiple views. Each view has distinct weights and aggregates information differently. This approach allows the model to learn both shared patterns (common among positive classes) and class-specific distinctive features, crucial for accurately classifying negative examples. The edge weights are dynamically updated based on learned node representations, ensuring an adaptive and effective learning process.
Multi-view Feature Construction
To reduce overlapping information and ensure each view captures distinct aspects, D-MVP constructs multiple feature views: structural, static, node, neighbor, and MLP features. These capture global structural patterns, graph-theoretic properties, intrinsic node attributes, local relational information, and raw unpropagated data, respectively. This comprehensive multi-view approach ensures robust and non-redundant feature learning.
Contrastive Loss
A novel contrastive loss is introduced to further guide the model in learning shared features among positive classes while separating them from unlabeled/negative classes. This loss encourages embeddings of positive class nodes to cluster together (positive pair loss) and penalizes positive-negative embeddings that are too close (negative pair loss). Combined with a conventional MPU loss, it reinforces the preservation of shared features and enhances distinctiveness.

Application in Cyberattack Detection
Scenario: A large enterprise faces sophisticated cyberattacks where attackers mimic legitimate user behavior within the network graph, making explicit negative labels unavailable. Traditional systems struggle with the absence of labeled negative data and the 'over-smoothing' effect where attacker and legitimate user profiles become indistinguishable.
Solution: D-MVP is deployed to analyze network traffic and user behavior patterns. By using multi-view feature propagation, it disentangles features related to 'normal' user behavior (shared positive features) from 'attack' patterns (distinctive positive features for specific attack types like DDoS, phishing).
Impact: The system achieves 88.1% F1-score in identifying various attack types, even without explicit negative labels. The adaptive edge weighting mechanism effectively prevents attackers from blending in. Furthermore, analyzing view-specific weights provides critical insights into which network features are indicative of specific threats, allowing for targeted defense strategies. The approach led to a 30% reduction in undetected threats compared to previous models.
