Triple-BERT: Do We Really Need MARL for Order Dispatch on Ride-Sharing Platforms?

arXiv:2510.03257v1 Announce Type: new Abstract: On-demand ride-sharing platforms, such as Uber and Lyft, face the intricate real-time challenge of bundling and matching passengers-each with distinct origins and destinations-to available vehicles, all while navigating significant system uncertainties. Due to the extensive…

Fast Witness Persistence for MRI Volumes via Hybrid Landmarking

arXiv:2510.04553v1 Announce Type: cross Abstract: We introduce a scalable witness-based persistent homology pipeline for full-brain MRI volumes that couples density-aware landmark selection with a GPU-ready witness filtration. Candidates are scored by a hybrid metric that balances geometric coverage against inverse…

Unsupervised Active Learning via Natural Feature Progressive Framework

arXiv:2510.04939v1 Announce Type: cross Abstract: The effectiveness of modern deep learning models is predicated on the availability of large-scale, human-annotated datasets, a process that is notoriously expensive and time-consuming. While Active Learning (AL) offers a strategic solution by labeling only…

Semantic-Inductive Attribute Selection for Zero-Shot Learning

arXiv:2510.03260v1 Announce Type: new Abstract: Zero-Shot Learning is an important paradigm within General-Purpose Artificial Intelligence Systems, particularly in those that operate in open-world scenarios where systems must adapt to new tasks dynamically. Semantic spaces play a pivotal role as they…

The Persistence of Neural Collapse Despite Low-Rank Bias

arXiv:2410.23169v2 Announce Type: replace Abstract: Neural collapse (NC) and its multi-layer variant, deep neural collapse (DNC), describe a structured geometry that occurs in the features and weights of trained deep networks. Recent theoretical work by Sukenik et al. using a…

Data-Driven Temperature Modelling of Machine Tools by Neural Networks: A Benchmark

arXiv:2510.03261v1 Announce Type: new Abstract: Thermal errors in machine tools significantly impact machining precision and productivity. Traditional thermal error correction/compensation methods rely on measured temperature-deformation fields or on transfer functions. Most existing data-driven compensation strategies employ neural networks (NNs) to…

Safety Subspaces are Not Linearly Distinct: A Fine-Tuning Case Study

arXiv:2505.14185v2 Announce Type: replace Abstract: Large Language Models (LLMs) rely on safety alignment to produce socially acceptable responses. However, this behavior is known to be brittle: further fine-tuning, even on benign or lightly contaminated data, can degrade safety and reintroduce…
