Kernel Model Validation: How To Do It, And Why You Should Care

arXiv:2509.15244v1 Announce Type: cross Abstract: Gaussian Process (GP) models are popular tools in uncertainty quantification (UQ) because they purport to furnish functional uncertainty estimates that can be used to represent model uncertainty. It is often difficult to state with precision…

Copyright and Competition: Estimating Supply and Demand with Unstructured Data

arXiv:2501.16120v2 Announce Type: replace-cross Abstract: We study the competitive and welfare effects of copyright in creative industries in the face of cost-reducing technologies such as generative artificial intelligence. Creative products often feature unstructured attributes (e.g., images and text) that are…

(SP)$^2$-Net: A Neural Spatial Spectrum Method for DOA Estimation

arXiv:2509.15475v1 Announce Type: cross Abstract: We consider the problem of estimating the directions of arrival (DOAs) of multiple sources from a single snapshot of an antenna array, a task with many practical applications. In such settings, the classical Bartlett beamformer…

Deep Reinforcement Learning with Gradient Eligibility Traces

arXiv:2507.09087v2 Announce Type: replace-cross Abstract: Achieving fast and stable off-policy learning in deep reinforcement learning (RL) is challenging. Most existing methods rely on semi-gradient temporal-difference (TD) methods for their simplicity and efficiency, but are consequently susceptible to divergence. While more…

Geometric Integration for Neural Control Variates

arXiv:2509.15538v1 Announce Type: cross Abstract: Control variates are a variance-reduction technique for Monte Carlo integration. The principle involves approximating the integrand by a function that can be analytically integrated, and integrating using the Monte Carlo method only the residual difference…

Query-Efficient Locally Private Hypothesis Selection via the Scheffe Graph

arXiv:2509.16180v1 Announce Type: cross Abstract: We propose an algorithm with improved query-complexity for the problem of hypothesis selection under local differential privacy constraints. Given a set of $k$ probability distributions $Q$, we describe an algorithm that satisfies local differential privacy,…

Subset Selection for Stratified Sampling in Online Controlled Experiments

arXiv:2509.15576v1 Announce Type: cross Abstract: Online controlled experiments, also known as A/B testing, are the digital equivalent of randomized controlled trials for estimating the impact of marketing campaigns on website visitors. Stratified sampling is a traditional technique for variance reduction…
