The kernel density estimator (KDE) based on a radial positive-semidefinite kernel may be viewed as a sample mean in a reproducing kernel Hilbert space. This mean can be viewed as the solution of a least squares problem in that space. Replacing the squared loss with a robust loss yields a robust kernel density estimator (RKDE). Previous work has shown that RKDEs are weighted kernel density estim...

In this paper we present a generalization of kernel density estimation called Convex Adaptive Kernel Density Estimation (CAKE) that replaces single bandwidth selection by a convex aggregation of kernels at all scales, where the convex aggregation is allowed to vary from one training point to another, treating the fundamental problem of heterogeneous smoothness in a novel way. Learning the CAKE ...

OBJECTIVE The aim was to evaluate carcass characteristics, cut yield, and meat quality in lambs that were fed different inclusion levels of palm kernel cake. METHODS Forty-five woolless castrated male Santa Inês crossbred sheep with an initial average body weight of 23.16±0.35 kg were used. The experimental design was a completely randomized design with five treatments, with palm kernel cake ...

to identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between norstar and zagros cultivars were evaluated in a randomized complete block design with three replications. the measured characters consisted of peduncle weight, ...

the persian walnut (juglans regia l.) is one of the most important horticultural crops grown in iran. this research was conducted to determine the variation in walnut germplasm grown in the arak region of iran during the 2007-2008 growing seasons. all of the selected genotypes originated from seed, and their phenological and pomological characteristics were evaluated. results indicated that the...

The goal of present experiments is to investigate the use of multiple kernel learning as a tool for pricing options in the context of Indian stock market for Nifty index options. In this paper, fair price of an option is predicted by Multiple Kernel Support Vector Regression (MKLSVR) using linear combinations of kernels and Single Kernel Support Vector Regression (SKSVR). Prices of option highl...

Two new techniques based on nonparametric estimation of probability densities are introduced which improve on the performance of equivalent robust methods currently employed in computer vision. The first technique draws from the projection pursuit paradigm in statistics, and carries out regression Mestimation with a weak dependence on the accuracy of the scale estimate. The second technique exp...

The present study was undertaken with the objective to determine the nature and magnitude of variability, degree of association between yield and it`s component characters and their direct, indirect effects on grain yield in rice (Oryza sativa L.). Thirty three genotypes were evaluated for identifying their efficiency with respect to 20 yield and quality traits. High heritability with high gene...

Identification and selection of promising genotypes of fruit tree are primary steps in breeding programs. The economic importance of almond production in the world has stimulated numerous studies related to breeding, quantitative and qualitative traits, the increase of yield and decrease production costs. In this study, morphological and pomological characteristics of 60 cultivar and superior g...
