QDFlow: A Python package for physics simulations of quantum dot devices

arXiv:2509.13298v1 Announce Type: cross Abstract: Recent advances in machine learning (ML) have accelerated progress in calibrating and operating quantum dot (QD) devices. However, most ML approaches rely on access to large, high-quality labeled datasets for training, benchmarking, and validation, with…

Spontaneous Kolmogorov-Arnold Geometry in Shallow MLPs

arXiv:2509.12326v1 Announce Type: new Abstract: The Kolmogorov-Arnold (KA) representation theorem constructs universal, but highly non-smooth inner functions (the first layer map) in a single (non-linear) hidden layer neural network. Such universal functions have a distinctive local geometry, a “texture,” which…

Safe Learning Under Irreversible Dynamics via Asking for Help

arXiv:2502.14043v2 Announce Type: replace Abstract: Most learning algorithms with formal regret guarantees essentially rely on trying all possible behaviors, which is problematic when some errors cannot be recovered from. Instead, we allow the learning agent to ask for help from…

FEDONet : Fourier-Embedded DeepONet for Spectrally Accurate Operator Learning

arXiv:2509.12344v1 Announce Type: new Abstract: Deep Operator Networks (DeepONets) have recently emerged as powerful data-driven frameworks for learning nonlinear operators, particularly suited for approximating solutions to partial differential equations (PDEs). Despite their promising capabilities, the standard implementation of DeepONets, which…

Linear Dimensionality Reduction for Word Embeddings in Tabular Data Classification

arXiv:2509.12346v1 Announce Type: new Abstract: The Engineers’ Salary Prediction Challenge requires classifying salary categories into three classes based on tabular data. The job description is represented as a 300-dimensional word embedding incorporated into the tabular features, drastically increasing dimensionality. Additionally,…

MillStone: How Open-Minded Are LLMs?

arXiv:2509.11967v2 Announce Type: replace Abstract: Large language models equipped with Web search, information retrieval tools, and other agentic capabilities are beginning to supplant traditional search engines. As users start to rely on LLMs for information on many topics, including controversial…
