In this study, we propose a dynamical memory strategy to efficiently control the size of the support set in a kernel-based Perceptron learning algorithm. The method consists of two operations, namely, the incremental and decremental projections. In the incremental projection, a new presented instance is either added to the support set or discarded depending(More)
In online learning with kernels, it is vital to control the size (budget) of the support set because of the curse of kernelization. In this paper, we propose two simple and effective stochastic strategies for controlling the budget. Both algorithms have an expected regret that is sublinear in the horizon. Experimental results on a number of benchmark data(More)
The incidence of thyroid cancer and its associated morbidity has shown the most rapid increase among all cancers since 1982, but the mechanisms involved in thyroid cancer, particularly significant key genes induced in thyroid cancer, remain undefined. In many studies, gene probes have been used to search for key genes involved in causing and facilitating(More)
Polycystic ovary syndrome (PCOS) is one of the most common female endocrine disorders. The aim of this study was to investigate possible associations between 45T/G and 276G/T variants of the ADIPOQ gene and susceptibility to PCOS. A meta-analysis of 11 published case-control studies on the 45T/G variant of the ADIPOQ gene (involving a total of 1176 patients(More)
Vascular endothelial growth factor (VEGF), known to play an important role in vascular homeostasis, vascular integrity and angiogenesis, is little known about the evolutionary relationship of its five members especially the role of gene duplication and natural selection in the evolution of the VEGF family. In this study, seventy-five full-length cDNA(More)
BACKGROUND Genes that have been subject to adaptive evolution can produce varying degrees of pathology or differing symptomatology. ErbB family receptor activation will initiate a number of downstream signaling pathways, such as mitogen-activated protein kinase (MAPK), activator of transcription (STAT), the modulation of calcium channels, and so on, all of(More)
OBJECTIVE The purpose of this article was to systematically review randomized controlled trials in which cold blood cardioplegia was compared with cold crystalloid cardioplegia for cardiac surgery. DESIGN Correlation studies were searched independently in the EMBASE, MEDLINE and Cochrane library databases. The primary endpoints of interest were(More)
