Learning Straight Flows: Variational Flow Matching for Efficient Generation

arXiv:2511.17583v1 Announce Type: new Abstract: Flow Matching has limited ability in achieving one-step generation due to its reliance on learned curved trajectories. Previous studies have attempted to address this limitation by either modifying the coupling distribution to prevent interpolant intersections…

LLM-Powered Text-Attributed Graph Anomaly Detection via Retrieval-Augmented Reasoning

arXiv:2511.17584v1 Announce Type: new Abstract: Anomaly detection on attributed graphs plays an essential role in applications such as fraud detection, intrusion monitoring, and misinformation analysis. However, text-attributed graphs (TAGs), in which node information is expressed in natural language, remain underexplored,…

SpectraNet: FFT-assisted Deep Learning Classifier for Deepfake Face Detection

arXiv:2511.19187v1 Announce Type: cross Abstract: Detecting deepfake images is crucial in combating misinformation. We present a lightweight, generalizable binary classification model based on EfficientNet-B6, fine-tuned with transformation techniques to address severe class imbalances. By leveraging robust preprocessing, oversampling, and optimization…

Optimizing Attention with Mirror Descent: Generalized Max-Margin Token Selection

arXiv:2410.14581v4 Announce Type: replace Abstract: Attention mechanisms have revolutionized several domains of artificial intelligence, such as natural language processing and computer vision, by enabling models to selectively focus on relevant parts of the input data. While recent work has characterized…

On the Stability of the Jacobian Matrix in Deep Neural Networks

arXiv:2506.08764v2 Announce Type: replace Abstract: Deep neural networks are known to suffer from exploding or vanishing gradients as depth increases, a phenomenon closely tied to the spectral behavior of the input-output Jacobian. Prior work has identified critical initialization schemes that…

Forecasting-based Biomedical Time-series Data Synthesis for Open Data and Robust AI

arXiv:2510.04622v2 Announce Type: replace Abstract: The limited data availability due to strict privacy regulations and significant resource demands severely constrains biomedical time-series AI development, which creates a critical gap between data requirements and accessibility. Synthetic data generation presents a promising…
