Variable Selection for Feature-Based Newsvendor

This paper forms the resulting $\ell_0$-constrained empirical newsvendor problem with $\ell_2$-regularization, establishes its computational hardness, and develops a mixed-integer second-order cone programming reformulation that strengthens the standard Big-$M$ formulation.

Matched Queries for Curvature and Density at Branching Junctions

This work addresses the inverse problem of matched score queries at noise scales $\sigma$ and $\lambda\sigma$ using matched subtraction to establish a perturbation bound and a conditional kernel-density-estimation rate.

Artificial Rosetta Stone: Constrained Maximum A Posteriori (MAP) Reconstruction of Symbolic Raga Sequences via Order-k Markov Models

This paper formalizes a mathematical framework for the Artificial Rosetta Stone, proposing the Artificial Rosetta Stone (ARS), and separates three claims often conflated: a symbolic sequence can be reconstructed probabilistically; a sequence can be consistent with an explicit grammar; and a historical performance can b...

A convolutional framework for detecting event-driven dynamics in energy price series

A general convolutional neural network framework for detecting heterogeneous event-driven dynamics in univariate time series windows and it is shown that the induced CNN class exactly represents classifiers based on range, maximum drawup, maximum drawdown and slope change, and uniformly approximates realised volatility...

Exact Global MCMC with Denoising Diffusion

This work shows that diffusion models learned with standard denoising loss can provide effective global MCMC proposals for complex high-dimensional target densities and offers preliminary evidence that the established scaling behavior of standard diffusion training transfers directly to exact sampling from high-dimensi...

Multi-Head Self Attention is a Parameter Identification Mechanism

It is proved that a multi-head scaled dot product attention can be viewed as a parameter identification strategy, and a purely mathematical/statistical explanation, identification, for why specific architectural choices in transformers may have improved performance is discussed.

When Metropolis and Hastings Meet Bradley and Terry: Exact MCMC From Preference Voting

This work introduces Pref-MH, a general exact MH sampler for judge-induced conditional distributions using only stochastic binary pairwise comparisons, and develops a valid accept/reject rule whose resulting Markov chain provably converges to the target distribution.
