1、xy平面 与 直和 https://en.wikipedia.org/wiki/Direct_sum For example, thexy-plane, a two-dimensionalvector space, can be thought of as the direct sum of two one-dimensional vector spaces, namely thexandyaxes. In this direct sum, thexandyaxes intersect only at the origin (the zero v...
In this paper, we have considered vector valued reproducing kernel Hilbert spaces (RKHS) H of entire functions associated with operator valued kernel functions. de Branges operators E=(E−,E+) analogous to de Branges matrices have been constructed with the help of pairs of Fredholm operator ...
This chapter explores vector spaces and linear transformations. A real vector space V is a set of objects, called vectors, together with two operations called addition and scalar multiplication. If x and y are in V and if α is a real number, then x + y are written for the sum of x...
We study the case when either X or Y is a sum X 1⊕F X 2 of two Banach spaces X 1 and X 2 by some two-dimensional Banach space F. We completely describe the class of those F such that for some spaces X 1 and X 2 there exists a Daugavet center acting from X 1⊕F X 2,...
is a vector of basis functions for the \(d\)th input \(x_d\), and \(\circ \) denotes the Hadamard (or element-wise) product. We use the following Gaussian kernels as the basis functions: $$\begin{aligned} \eta _b\big ( \varvec{y} \big )&:= \exp \left( -\frac{\Vert ...

where \({{{\mathbf{t}}}_i\) is the ith column vector of the TM, and the bracket indicates the mean of the vector elements \(\left\langle \cdot \right\rangle = {\textstyle{1 \over M}}\mathop {\sum}\nolimits_{i = 1}^M {}\). The column vector \({{{\mathbf{t}}}_i\...
12.1.1 Vector spaces Definition 12.1.1 A vector space is a set V of elements called vectors that have operations called vector addition and scalar multiplication defined so that the following conditions hold for any u,u,w∈V and scalars a, and b. • Closure properties c-1. u + v...

Introduction Recently, the availability of existing central electric energy generation has not been sufficient to meet the high and growing demand...
(LLW) model [19], and the Quadratic Loss Multi-Class Support Vector machine (M-SVM2) model [20]. These four models are used as a solution to overcome the weaknesses of the indirect M-SVM models widely used in this problem. Each used M-SVM considers the returned parameters set by ...
