Effective Test-Time Scaling of Discrete Diffusion through Iterative Refinement

arXiv:2511.05562v1 Announce Type: new Abstract: Test-time scaling through reward-guided generation remains largely unexplored for discrete diffusion models despite its potential as a promising alternative. In this work, we introduce Iterative Reward-Guided Refinement (IterRef), a novel test-time scaling method tailored to…

Diversified Flow Matching with Translation Identifiability

arXiv:2511.05558v1 Announce Type: new Abstract: Diversified distribution matching (DDM) finds a unified translation function mapping a diverse collection of conditional source distributions to their target counterparts. DDM was proposed to resolve content misalignment issues in unpaired domain translation, achieving translation…

Revisiting Stochastic Approximation and Stochastic Gradient Descent

arXiv:2505.11343v3 Announce Type: replace-cross Abstract: In this paper, we introduce a new approach to proving the convergence of the Stochastic Approximation (SA) and the Stochastic Gradient Descent (SGD) algorithms. The new approach is based on a concept called GSLLN (Generalized…

Fine-Tuning Vision-Language Models for Multimodal Polymer Property Prediction

arXiv:2511.05577v1 Announce Type: new Abstract: Vision-Language Models (VLMs) have shown strong performance in tasks like visual question answering and multimodal text generation, but their effectiveness in scientific domains such as materials science remains limited. While some machine learning methods have…

Walsh-Hadamard Neural Operators for Solving PDEs with Discontinuous Coefficients

arXiv:2511.07347v1 Announce Type: cross Abstract: Neural operators have emerged as powerful tools for learning solution operators of partial differential equations (PDEs). However, standard spectral methods based on Fourier transforms struggle with problems involving discontinuous coefficients due to the Gibbs phenomenon…
