Graph Contrastive Learning via Spectral Graph Alignment

arXiv:2512.07878v1 Announce Type: new Abstract: Given augmented views of each input graph, contrastive learning methods (e.g., InfoNCE) optimize pairwise alignment of graph embeddings across views while providing no mechanism to control the global structure of the view specific graph-of-graphs built…

Evaluating and Preserving High-level Fidelity in Super-Resolution

arXiv:2512.07037v2 Announce Type: replace-cross Abstract: Recent image Super-Resolution (SR) models are achieving impressive effects in reconstructing details and delivering visually pleasant outputs. However, the overpowering generative ability can sometimes hallucinate and thus change the image content despite gaining high visual…

Nonlinear Optimization with GPU-Accelerated Neural Network Constraints

arXiv:2509.22462v2 Announce Type: replace Abstract: We propose a reduced-space formulation for optimizing over trained neural networks where the network’s outputs and derivatives are evaluated on a GPU. To do this, we treat the neural network as a “gray box” where…

ReJump: A Tree-Jump Representation for Analyzing and Improving LLM Reasoning

arXiv:2512.00831v2 Announce Type: replace Abstract: Large Reasoning Models (LRMs) are Large Language Models (LLMs) explicitly trained to generate long-form Chain-of-Thoughts (CoTs), achieving impressive success on challenging tasks like math and programming. However, their underlying reasoning “algorithms” remain poorly understood. To…
