TiRex-2 is a recurrent xLSTM time series foundation model for multivariate forecasting with future covariates and constant-cost streaming that reports SOTA zero-shot results on GIFT-Eval and fev-bench.
Kolmogorov n-width theory plus PRESS statistics yield closed-form optimal spline resolution; KORE estimates bias/noise scales from two pilots and matches CV performance with far fewer fits.
Predictively consistent priors let complex Bayesian models match or beat the out-of-sample performance of selected simpler models across linear, logistic, and nonlinear examples without explicit selection.
PliableBVS is a new Bayesian hierarchical spike-and-slab model for simultaneous selection of high-dimensional main effects and interactions under an asymmetric weak hierarchical constraint, shown to outperform pliable lasso in simulations.
A Bayesian search calibrated on 3,493 meteorite analyses finds strong evidence for a siderophile-enriched processed template in only a small fraction of 697 polluted white dwarf records, with posterior medians of 0.011 and 0.041.
Proves well-posedness and unique invariant measure (delta at 0 plus gamma density) for sticky CIR, derives Green's function for exact sampling, and analyzes MH and ULA samplers with explicit bias for the potential case via Girsanov.
Affordance-driven Croissant Charts improve performance on probability comparison tasks with normal distributions, validated in a preregistered study with 808 participants.
Unifying framework for CTree, MOB and GUIDE shows model scores without dichotomization yield higher power for covariate selection than residuals or dichotomized scores in many scenarios.
CMS excludes narrow-width singlet vector-like B' quarks with masses 0.8-1.23 TeV in the tW channel using neural-network tagging and data-driven background modeling.
Proves oracle Bernstein-von Mises theorem for fractional posterior under supportwise likelihood assumptions in sparse GLMs with spike-and-slab priors.
FIRE-2 simulations show Milky Way analogs form in two phases whose transition correlates with the host halo's shift from fast to slow accretion, driven by two distinct star-formation modes.
