From Geometry to Generalization: Why Row Normalization Can Beat Adam and Muon

Different optimizers can fit the same training data while selecting classifiers with substantially different geometries, but whether this difference provably affects population performance remains unclear. We show that row-wise normalization can achieve strictly higher population accuracy than full-batch Adam, a proxy...

From Log-Odds to Shapley Values: An Explanatory Geometry for the Weighted Naive Bayes Classifier

This paper studies the construction of an explanatory space for a weighted naive Bayes classifier from the supervised representation induced by the model. We start from the classical supervised distance based on conditional log-likelihoods and introduce a discriminative reformulation based on log-odds, which is more di...

Discovering Global False Negatives On the Fly for Self-supervised Contrastive Learning

In self-supervised contrastive learning, negative pairs are typically constructed using an anchor image and a sample drawn from the entire dataset, excluding the anchor. However, this approach can result in the creation of negative pairs with similar semantics, referred to as "false negatives", leading to their embeddi...

When Lower Reconstruction Loss Hurts: Distributionally Robust Refinement for Low-Bit LLM Quantization

Weight-only post-training quantization (PTQ) relies heavily on reconstruction loss minimization to preserve model quality at low precision. We show that the weights favored by minimizing this loss need not yield better model performance on new tasks. In fact, we find that lower reconstruction loss can even degrade mode...

Quantifying Free-Roaming Horse Body Condition: A Methodological Investigation Using Game Cameras and Observer Bias Corrections

Large populations of free-roaming horses (Equus caballus ) inhabit the western United States, Australia, and other arid and semi-arid rangelands globally. In the United States, horse body condition has been the impetus for gathering and removing horses under an emergency designation and has been noted as a common chron...

Adult age estimation from the pubic symphysis and sternal rib: A combined Bayesian revision of the Hartnett methods

Abstract Two of the most commonly used methods for adult age estimation in forensic anthropology utilize the pubic symphysis on the pubic bone and the sternal end of the fourth rib. Currently, there are no age estimation methods that combine visual assessments of the joints of both the pubic symphysis and sternal end o...
