When Does Delegation Beat Majority? A Delegation-Based Aggregator for Multi-Sample LLM Inference
arXiv:2606.08098v1 Announce Type: new Abstract: Majority voting over sampled answers is the dominant unsupervised aggregator for multi-sample LLM inference. We show that piping the signals every sample carries into a delegation-based aggregator (Propagational Proxy Voting, PPV) yields an unsupervised consensus rule that beats majority on MMLU-Pro by +1.5 pp overall and +2.24 pp on the non-trivial subset (paired McNemar p ~ 1.0e-14, n = 8,099).
Fair Decisions from Calibrated Scores: Achieving Optimal Classification While Satisfying Sufficiency
arXiv:2602.07285v2 Announce Type: replace Abstract: Binary classification based on predicted probabilities (scores) is a fundamental task in supervised machine learning. While thresholding scores is Bayes-optimal in the unconstrained setting, using a single threshold generally violates statistical group fairness constraints. Under independence (statistical parity) and separation (equalized odds), such thresholding suffices when the scores already satisfy the corresponding criterion.
A Pathology Foundation Model for Gastric Cancer with Real-World Validation
arXiv:2606.04792v1 Announce Type: new Abstract: Gastric cancer remains a major cause of cancer mortality, yet its histological and molecular heterogeneity complicates diagnosis and risk stratification. General-purpose pathology foundation models (PFMs) often plateau on fine-grained endpoints central to gastric cancer care, and few have undergone rigorous prospective validation or clinical reader studies. We present GRACE, a Gastric-specific foundation model for Real-world Assessment and...
From the Octagon to the Oval office: White, Trump and a 25-year friendship
THE 28TH INSTALLMENT of the Ultimate Fighting Championship was a trial run. Though 36 states had banned the UFC, the New Jersey State Athletic Control Board allowed the then-owner, Semaphore Entertainment Group, to host its first sanctioned event on Nov. 17, 2000, at the Taj Mahal in Atlantic City, a hotel and casino owned by real estate mogul Donald Trump. Fighter Randy Couture returned to the UFC for the first time since 1997 and recaptured his heavyweight championship against Kevin...
