GP-UCB algorithm's suboptimality revealed in new research
A new paper published on arXiv investigates the limitations of the Gaussian Process Upper Confidence Bound (GP-UCB) algorithm. Researchers have established upper bounds on its cumulative regret, but this work explores w…

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 …

New method tackles dynamic regret in RKHS using subspace approximation
Researchers have developed a new method for online regression in reproducing kernel Hilbert spaces (RKHS) that addresses dynamic regret. The approach adapts finite-dimensional techniques to the RKHS setting using subspa…

New paper explores identifiability and stability in generative drifting frameworks
This paper introduces companion-elliptic kernels, a class that includes the Laplace kernel and is defined by a specific coupling with a companion function. The research proves that for kernels in this class, the driftin…
