When majority rules, minority loses: bias amplification of gradient descent

arXiv:2505.13122v2 Announce Type: replace Abstract: Despite growing empirical evidence of bias amplification in machine learning, its theoretical foundations remain poorly understood. We develop a formal framework for majority-minority learning tasks, showing how standard training can favor majority groups and produce…

Self-Attention to Operator Learning-based 3D-IC Thermal Simulation

arXiv:2510.15968v1 Announce Type: new Abstract: Thermal management in 3D ICs is increasingly challenging due to higher power densities. Traditional PDE-solving-based methods, while accurate, are too slow for iterative design. Machine learning approaches like FNO provide faster alternatives but suffer from…

Accelerated Evolving Set Processes for Local PageRank Computation

arXiv:2510.08010v3 Announce Type: replace Abstract: This work proposes a novel framework based on nested evolving set processes to accelerate Personalized PageRank (PPR) computation. At each stage of the process, we employ a localized inexact proximal point iteration to solve a…

arXiv:2510.15970v1 Announce Type: new Abstract: High-quality training data is the foundation of machine learning and artificial intelligence, shaping how models learn and perform. Although much is known about what types of data are effective for training, the impact of the…

Flow Matching for Accelerated Simulation of Atomic Transport in Crystalline Materials

arXiv:2410.01464v4 Announce Type: replace-cross Abstract: Atomic transport underpins the performance of materials in technologies such as energy storage and electronics, yet its simulation remains computationally demanding. In particular, modeling ionic diffusion in solid-state electrolytes (SSEs) requires methods that can overcome…

Bolster Hallucination Detection via Prompt-Guided Data Augmentation

arXiv:2510.15977v1 Announce Type: new Abstract: Large language models (LLMs) have garnered significant interest in AI community. Despite their impressive generation capabilities, they have been found to produce misleading or fabricated information, a phenomenon known as hallucinations. Consequently, hallucination detection has…
