Discrete Solution Operator Learning for Geometry-Dependent PDEs

arXiv:2601.09143v1 Announce Type: new Abstract: Neural operator learning accelerates PDE solution by approximating operators as mappings between continuous function spaces. Yet in many engineering settings, varying geometry induces discrete structural changes, including topological changes, abrupt changes in boundary conditions or…

Stock Price Responses to Firm-Level News in Supply Chain Networks

arXiv:2409.06255v5 Announce Type: replace-cross Abstract: This study examines how positive and negative news about firms is associated with stock prices and whether these associations extend to firms’ suppliers and clients connected through supply chain relationships, using large samples of publicly…

Interpretable Probability Estimation with LLMs via Shapley Reconstruction

arXiv:2601.09151v1 Announce Type: new Abstract: Large Language Models (LLMs) demonstrate potential to estimate the probability of uncertain events, by leveraging their extensive knowledge and reasoning capabilities. This ability can be applied to support intelligent decision-making across diverse fields, such as…

Representing Molecules with Algebraic Data Types: Beyond SMILES and SELFIES

arXiv:2501.13633v4 Announce Type: replace-cross Abstract: Algebraic data types (ADTs) let a representation specify at the type level what molecular values are valid and what transformations are meaningful. We propose a molecular representation as a family of typed ADTs that separates…

Efficient Clustering in Stochastic Bandits

arXiv:2601.09162v1 Announce Type: new Abstract: We study the Bandit Clustering (BC) problem under the fixed confidence setting, where the objective is to group a collection of data sequences (arms) into clusters through sequential sampling from adaptively selected arms at each…

DiSCo: Making Absence Visible in Intelligent Summarization Interfaces

arXiv:2601.07229v2 Announce Type: replace-cross Abstract: Intelligent interfaces increasingly use large language models to summarize user-generated content, yet these summaries emphasize what is mentioned while overlooking what is missing. This presence bias can mislead users who rely on summaries to make…
