New theory explains cross-validation variance, favors K-fold
A new paper published on arXiv introduces a theoretical framework for understanding the variance in cross-validation estimates of predictive performance. The research establishes an exact finite-sample identity for this…

New formulas predict predictive model performance before data collection
Researchers have developed new formulas to estimate the expected out-of-sample R-squared and correlation for predictive models using ordinary least squares and ridge regression. These formulas, detailed in a paper submi…

Adaptive RBF-KAN improves efficiency with new kernels and data-driven shape parameters
Researchers have developed an enhanced version of Kolmogorov-Arnold Networks (KANs) called adaptive RBF-KAN, which improves computational efficiency and flexibility. This new approach replaces the fixed Gaussian radial …
