Density Estimation with Mercer Kernels
We present a new method for density estimation based on Mercer kernels. The density estimate can be understood as the density induced on a data manifold by a mixture of Gaussians fit in a feature space. As is usual, the feature space and data manifold are defined with any suitable positive-definite kernel function. We modify the standard EM algorithm for mixtures of Gaussians to infer the param...
متن کاملReproducing kernel Hilbert spaces and Mercer theorem
We characterize the reproducing kernel Hilbert spaces whose elements are p-integrable functions in terms of the boundedness of the integral operator whose kernel is the reproducing kernel. Moreover, for p = 2 we show that the spectral decomposition of this integral operator gives a complete description of the reproducing kernel.

متن کاملIntroducing George L. Spaeth, the 2010 recipient of the Weisenfeld Award.
It is a great pleasure and honor, as well as a somewhat daunting task, to introduce the 2010 ARVO Weisenfeld Award recipient—daunting in that George L. Spaeth, MD, manages somehow to be not one but many men, much as a Hindu god comprises many entities or avatars. First among these avatars is George Spaeth, the quintessential Philadelphian. Steeped in the Quaker culture of collegiality and indep...
متن کاملThe Mercer online interactive chaotic pendulum
remotely control through the Internet. Our objective is threefold. We are attempting to provide an educational resource for chaos, demonstrate a new technology, and experiment with a new method of laboratory education. Figure 1 shows the pendulum control panel. As students vary the driving frequency, they can watch the pendulum's motion switch from simple periodic motion to chaotic motion. The ...
