arXiv — cs.CVThursday, November 27, 2025 at 5:00:00 AM
  • GFT-GCN introduces a novel privacy-preserving framework for 3D face recognition, utilizing spectral graph learning and diffusion-based template protection to enhance security in biometric systems. This method leverages the Graph Fourier Transform and Graph Convolutional Networks to extract distinctive features from 3D face meshes while ensuring that raw biometric data remains on the client device.
  • The significance of GFT-GCN lies in its ability to provide robust security for biometric templates, addressing a critical concern in high-security applications where the risk of data breaches is prevalent. By ensuring that templates are irreversible and unlinkable, the framework enhances user privacy and trust in biometric technologies.
  • This development reflects a growing trend in artificial intelligence towards integrating advanced graph-based techniques for improved performance and security in various applications. The challenges faced by Graph Neural Networks, such as oversmoothing, highlight the ongoing research efforts to optimize these models, indicating a broader commitment to enhancing the efficiency and effectiveness of AI systems.

Time-Aware and Transition-Semantic Graph Neural Networks for Interpretable Predictive Business Process Monitoring
PositiveArtificial Intelligence
A new framework for Predictive Business Process Monitoring (PBPM) has been proposed, utilizing Time-Aware and Transition-Semantic Graph Neural Networks (GNNs) to enhance the interpretability and accuracy of predictions based on historical event logs. This framework addresses limitations in existing GNN-based models by integrating a time decay attention mechanism and embedding transition type semantics into edge features.
