Training Robust Graph Neural Networks by Modeling Noise Dependencies

arXiv:2502.19670v2 Announce Type: replace Abstract: In real-world applications, node features in graphs often contain noise from various sources, leading to significant performance degradation in GNNs. Although several methods have been developed to enhance robustness, they rely on the unrealistic assumption…

Embedding principle of homogeneous neural network for classification problem

arXiv:2505.12419v3 Announce Type: replace Abstract: In this paper, we study the Karush-Kuhn-Tucker (KKT) points of the associated maximum-margin problem in homogeneous neural networks, including fully-connected and convolutional neural networks. In particular, We investigates the relationship between such KKT points across…

Machine Unlearning under Overparameterization

arXiv:2505.22601v2 Announce Type: replace Abstract: Machine unlearning algorithms aim to remove the influence of specific training samples, ideally recovering the model that would have resulted from training on the remaining data alone. We study unlearning in the overparameterized setting, where…

Watermarking Autoregressive Image Generation

arXiv:2506.16349v2 Announce Type: replace Abstract: Watermarking the outputs of generative models has emerged as a promising approach for tracking their provenance. Despite significant interest in autoregressive image generation models and their potential for misuse, no prior work has attempted to…

SALT: Step-level Advantage Assignment for Long-horizon Agents via Trajectory Graph

arXiv:2510.20022v1 Announce Type: new Abstract: Large Language Models (LLMs) have demonstrated remarkable capabilities, enabling language agents to excel at single-turn tasks. However, their application to complex, multi-step, and long-horizon tasks remains challenging. While reinforcement learning (RL) offers a promising avenue…

The Temporal Graph of Bitcoin Transactions

arXiv:2510.20028v1 Announce Type: new Abstract: Since its 2009 genesis block, the Bitcoin network has processed num{>1.08} billion (B) transactions representing num{>8.72}B BTC, offering rich potential for machine learning (ML); yet, its pseudonymity and obscured flow of funds inherent in its…
