H3: A Healthcare Three-Hop Index for Physician Referral Network Prediction

arXiv:2605.02150v1 Announce Type: cross Abstract: Accurate prediction of physician referral links is essential for optimizing care coordination and reducing fragmentation in healthcare delivery. However, existing computational methods, ranging from triadic closure heuristics to graph neural networks, fail to capture the…

Black-box optimization of noisy functions with unknown smoothness

arXiv:2605.02462v1 Announce Type: cross Abstract: We study the problem of black-box optimization of a function f of any dimension, given function evaluations perturbed by noise. The function is assumed to be locally smooth around one of its global optima, but…

Structured Analytic Coherent Point Drift for Non-Rigid Point Set Registration

arXiv:2605.00934v1 Announce Type: new Abstract: We introduce Analytic-CPD, a structured analytic variant of coherent point drift for non-rigid point set registration. The method retains the CPD posterior correspondence layer, but replaces the point-indexed Gaussian-kernel displacement-field M-step with a finite-dimensional structured…

Fairness-Aware Multi-Group Target Detection in Online Discussion

arXiv:2407.11933v5 Announce Type: replace Abstract: Target-group detection is the task of detecting which group(s) a piece of content is “directed at or about”. Applications include targeted marketing, content recommendation, and group-specific content assessment. Key challenges include: 1) that a single…
