Summary The performance of adaptive estimators that employ embedding in reproducing kernel Hilbert spaces (RKHS) depends on the choice location basis centers. Parameter convergence and error approximation rates depend where how centers are distributed state‐space. In this article, we develop theory relates parameter to position We criteria for choosing a specific class systems by exploiting fac...
Kernel size is an important component of grain yield in maize breeding programs. To extend the understanding on the genetic basis of kernel size traits (i.e., kernel length, kernel width and kernel thickness), we developed a set of four-way cross mapping population derived from four maize inbred lines with varied kernel sizes. In the present study, we investigated the genetic basis of natural v...
Kernel methods have been applied successfully in many applications. The kernel matrix plays an important role in kernel-based learning methods, but the “ideal” kernel matrix is usually unknown in practice and needs to be estimated. In this paper, we propose to directly learn the “ideal” kernel matrix (called the optimal neighborhood kernel matrix) from a pre-specified kernel matrix for improved...
Following the very recent line of work on the “generalized min-max” (GMM) kernel [7], this study proposes the “generalized intersection” (GInt) kernel and the related “normalized generalized min-max” (NGMM) kernel. In computer vision, the (histogram) intersection kernel has been popular, and the GInt kernel generalizes it to data which can have both negative and positive entries. Through an ext...
