Investigating Data Interventions for Subgroup Fairness: An ICU Case Study

arXiv:2604.03478v1 Announce Type: new Abstract: In high-stakes settings where machine learning models are used to automate decision-making about individuals, the presence of algorithmic bias can exacerbate systemic harm to certain subgroups of people. These biases often stem from the underlying…

SPORE: Skeleton Propagation Over Recalibrating Expansions

arXiv:2511.00064v5 Announce Type: replace Abstract: Clustering is a foundational task in data analysis, yet most algorithms impose rigid assumptions on cluster geometry: centroid-based methods favor convex structures, while density-based approaches break down under variable local density or moderate dimensionality. This…

Improving Feasibility via Fast Autoencoder-Based Projections

arXiv:2604.03489v1 Announce Type: new Abstract: Enforcing complex (e.g., nonconvex) operational constraints is a critical challenge in real-world learning and control systems. However, existing methods struggle to efficiently enforce general classes of constraints. To address this, we propose a novel data-driven…

Online learning of smooth functions on $mathbb{R}$

arXiv:2604.03525v1 Announce Type: new Abstract: We study adversarial online learning of real-valued functions on $mathbb{R}$. In each round the learner is queried at $x_tinmathbb{R}$, predicts $hat y_t$, and then observes the true value $f(x_t)$; performance is measured by cumulative $p$-loss…

Simple yet Effective: Low-Rank Spatial Attention for Neural Operators

arXiv:2604.03582v1 Announce Type: new Abstract: Neural operators have emerged as data-driven surrogates for solving partial differential equations (PDEs), and their success hinges on efficiently modeling the long-range, global coupling among spatial points induced by the underlying physics. In many PDE…
