BlockGPT: Spatio-Temporal Modelling of Rainfall via Frame-Level Autoregression

arXiv:2510.06293v1 Announce Type: new Abstract: Predicting precipitation maps is a highly complex spatiotemporal modeling task, critical for mitigating the impacts of extreme weather events. Short-term precipitation forecasting, or nowcasting, requires models that are not only accurate but also computationally efficient…

SDAR: A Synergistic Diffusion-AutoRegression Paradigm for Scalable Sequence Generation

arXiv:2510.06303v1 Announce Type: new Abstract: We propose SDAR, a Synergistic Diffusion-Autoregression paradigm that unifies the training efficiency of autoregressive models with the parallel inference capability of diffusion. Instead of costly end-to-end diffusion training, SDAR performs a lightweight paradigm conversion that…

On knot detection via picture recognition

arXiv:2510.06284v1 Announce Type: new Abstract: Our goal is to one day take a photo of a knot and have a phone automatically recognize it. In this expository work, we explain a strategy to approximate this goal, using a mixture of…

Testing Support Size More Efficiently Than Learning Histograms

arXiv:2410.18915v3 Announce Type: replace-cross Abstract: Consider two problems about an unknown probability distribution $p$: 1. How many samples from $p$ are required to test if $p$ is supported on $n$ elements or not? Specifically, given samples from $p$, determine whether…

Relational Transformer: Toward Zero-Shot Foundation Models for Relational Data

arXiv:2510.06377v1 Announce Type: new Abstract: Pretrained transformers readily adapt to new sequence modeling tasks via zero-shot prompting, but relational domains still lack architectures that transfer across datasets and tasks. The core challenge is the diversity of relational data, with varying…

Token-based Audio Inpainting via Discrete Diffusion

arXiv:2507.08333v3 Announce Type: replace-cross Abstract: Audio inpainting seeks to restore missing segments in degraded recordings. Previous diffusion-based methods exhibit impaired performance when the missing region is large. We introduce the first approach that applies discrete diffusion over tokenized music representations…

Monte Carlo Permutation Search

arXiv:2510.06381v1 Announce Type: new Abstract: We propose Monte Carlo Permutation Search (MCPS), a general-purpose Monte Carlo Tree Search (MCTS) algorithm that improves upon the GRAVE algorithm. MCPS is relevant when deep reinforcement learning is not an option, or when the…
