Nonlinear reconciliation: Error reduction theorems

arXiv:2507.22500v2 Announce Type: replace Abstract: Forecast reconciliation, an ex-post technique applied to forecasts that must satisfy constraints, has been a prominent topic in the forecasting literature over the past two decades. Recently, several efforts have sought to extend reconciliation methods…

Comparative Assessment of Concrete Compressive Strength Prediction at Industry Scale Using Embedding-based Neural Networks, Transformers, and Traditional Machine Learning Approaches

arXiv:2601.09096v1 Announce Type: new Abstract: Concrete is the most widely used construction material worldwide; however, reliable prediction of compressive strength remains challenging due to material heterogeneity, variable mix proportions, and sensitivity to field and environmental conditions. Recent advances in artificial…

ELUTQ: Optimizing Quantization Accuracy under LUT-Based Computation for Edge LLMs

arXiv:2510.19482v3 Announce Type: replace Abstract: Weight quantization effectively reduces memory consumption and enable the deployment of Large Language Models on edge devices, yet existing hardware-friendly methods often rely on uniform quantization, which suffers from poor weight-distribution fitting and high dequantization…

Enhancing Imbalanced Electrocardiogram Classification: A Novel Approach Integrating Data Augmentation through Wavelet Transform and Interclass Fusion

arXiv:2601.09103v1 Announce Type: new Abstract: Imbalanced electrocardiogram (ECG) data hampers the efficacy and resilience of algorithms in the automated processing and interpretation of cardiovascular diagnostic information, which in turn impedes deep learning-based ECG classification. Notably, certain cardiac conditions that are…

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…
