Reproducing kernel Hilbert space Mapping the points to a higher dimensional feature space http://www.gatsby.ucl.ac.uk/~gretton/coursefiles/lecture4_introToRKHS.pdf [We next show that every reproducing kernel Hilbert space has a unique positive defini…

In recent years, Kernel methods have received major attention, particularly due to the increased popularity of the Support Vector Machines. Kernel functions can be used in many applications as they provide a simple bridge from linearity to non-linear…

1. 用滑动平均估计局部均值 滑动平均(exponential moving average),或者叫做指数加权平均(exponentially weighted moving average),可以用来估计变量的局部均值,使得变量的更新与一段时间内的历史取值有关. 变量$v$在$t$时刻记为$v_t$,$\theta_t$为变量$v$在$t$时刻的取值,即在不使用滑动平均模型时$v_t = \theta_t$,在使用滑动平均模型后,$v_t$的更新公式如下: \begin{equation} …

http://mathworld.wolfram.com/HilbertSpace.html A Hilbert space is a vector space  with an inner product  such that the norm defined by turns  into a complete metric space. If the metric defined by the norm is not complete, then  is instead known as a…
