GateRA: Token-Aware Modulation for Parameter-Efficient Fine-Tuning

arXiv:2511.17582v1 Announce Type: new Abstract: Parameter-efficient fine-tuning (PEFT) methods, such as LoRA, DoRA, and HiRA, enable lightweight adaptation of large pre-trained models via low-rank updates. However, existing PEFT approaches apply static, input-agnostic updates to all tokens, disregarding the varying importance…

The Value of Personalized Recommendations: Evidence from Netflix

arXiv:2511.07280v3 Announce Type: replace-cross Abstract: Personalized recommendation systems shape much of user choice online, yet their targeted nature makes separating out the value of recommendation and the underlying goods challenging. We build a discrete choice model that embeds recommendation-induced utility,…

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…
