Chess Signatures of Play

Christian Turk, Nicholas Polson

A game of chess is a stream: a time-ordered sequence of moves, each carrying an engine evaluation, a measure of accuracy, a measure of position complexity, and a clock reading. We…

E-Values, Bayes Risk, Dual Role of Markov's Inequality

Nicholas G. Polson, Daniel Zantedeschi

Two approaches to hypothesis testing, e-value testing and Bayes risk minimisation, both invoke Markov's inequality to control error probabilities. They differ in which distribution…

Kakeya Conjecture and Conditional Kolmogorov Complexity

Nicholas G. Polson, Daniel Zantedeschi

This paper develops an information-theoretic framework for algorithmic complexity under regular identifiable fibering. The central question is: when a decoder is given information…

A New Look at Bayesian Testing

Jyotishka Datta, Nicholas G. Polson, Vadim Sokolov +1

We identify the critical deviation scale governing Bayesian evidence accumulation in regular parametric testing. Under integrated Bayes risk with zero-one loss, the risk-optimal re…

Bayes with No Shame: Admissibility Geometries of Predictive Inference

Nicholas G. Polson, Daniel Zantedeschi

Modern predictive systems combine predictors, sequential monitors, prediction sets, and online strategies, each with a different certificate of optimality. We study four criterion-…

Bayes Risk for Goodness of Fit Tests

Nicholas G. Polson, Vadim Sokolov, Daniel Zantedeschi

We develop a unified framework for goodness-of-fit (GOF) testing through the lens of Bayes risk. Classical GOF procedures are commonly calibrated either at fixed significance level…

Conformal Prediction = Bayes?

Jyotishka Datta, Nicholas G. Polson, Vadim Sokolov +1

Conformal prediction (CP) is widely presented as distribution-free predictive inference with finite-sample marginal coverage under exchangeability. We argue that CP is best underst…

Entropy-Regularized Inference: A Predictive Approach

Nicholas G. Polson, Daniel Zantedeschi

Predictive inference requires balancing statistical accuracy against informational complexity, yet the choice of complexity measure is usually imposed rather than derived. We treat…

Bayesian Prediction under Moment Conditioning

Nicholas G. Polson, Daniel Zantedeschi

Moment restrictions specify a class of laws, not a predictive model. We obtain one by conditioning an independent sample from a reference law on its empirical moments, and define p…

De Finetti + Sanov = Bayes: Exchangeable Prediction under Moment Constraints

Nicholas G. Polson, Daniel Zantedeschi

We study exchangeable prediction when empirical-moment constraints define each active finite horizon N. The relevant law is the de Finetti mixture conditioned on E_N = {Phat_N in E…

Polynomial Log-Marginals and Tweedie's Formula : When Is Bayes Possible?

Jyotishka Datta, Nicholas G. Polson

Motivated by Tweedie's formula for the Compound Decision problem, we examine the theoretical foundations of empirical Bayes estimators that directly model the marginal density $m(y…

Prediction-Powered Inference with Inverse Probability Weighting

Jyotishka Datta, Nicholas G. Polson

Prediction-powered inference (PPI) is a recent framework for valid statistical inference with partially labeled data, combining model-based predictions on a large unlabeled set wit…

Bayesian ICA with super-Gaussian Source Priors

Jyotishka Datta, Soham Ghosh, Nicholas G. Polson

Independent Component Analysis (ICA) plays a central role in modern machine learning as a flexible framework for feature extraction. We introduce a horseshoe-type prior with a late…

Pochhammer Priors for Sparse Count Models

Yuexi Wang, Nicholas G. Polson

Bayesian hierarchical models are commonly employed for inference in count datasets, as they account for multiple levels of variation by incorporating prior distributions for parame…

Bayesian Regularization: From Tikhonov to Horseshoe

Nicholas G. Polson, Vadim Sokolov

Bayesian regularization is a central tool in modern-day statistical and machine learning methods. Many applications involve high-dimensional sparse signal recovery problems. The go…

Deep Learning in Characteristics-Sorted Factor Models

Guanhao Feng, Jingyu He, Nicholas G. Polson +1

This paper presents an augmented deep factor model that generates latent factors for cross-sectional asset pricing. The conventional security sorting on firm characteristics for co…

Dynamic Trees for Learning and Design

Matthew A. Taddy, Robert B. Gramacy, Nicholas G. Polson

Dynamic regression trees are an attractive option for automatic regression and classification with complicated response surfaces in on-line application settings. We create a sequen…
