gram matrix看定义是<xi,xj>的kernel矩阵。样本量是3,所以是3*3的。
Gram Matrix实际上可看做是feature之间的偏心协方差矩阵(即没有减去均值的协方差矩阵),在feature map...
We propose to use the optimal kernel gram matrices learnt from the kernel gram matrix of the base kernels in pattern analysis tasks such as clustering, multi-class pattern classification and nonlinear principal component analysis. We consider the commonly used kernels such as linear kernel, ...
(格莱姆矩阵) 在[2]中,我们从style transfer中使用的Gram matrix出发,试图解释为什么Gram matrix可以代表一个图片的style这个问题。这是我看完style transfer的paper后感觉最为迷惑的一点。一个偶然的机会,我们发现这个匹配两张图的Gram matrix,其实数学上严格等价于极小化这两张图deep activation的2nd poly kernel的...
We describe an approach to kernel selection in Support Vector Machines (SVMs) driven by the Gram matrix. Our study extracts properties from this matrix (e.g., Fisher's discriminant, Bregman's divergence) using different kernel functions (lin-ear, polynomial, Gaussian, Laplacian, Bessel and ANOVA...

We present in this work a new family of kernels to compare positive measures on arbitrary spaces $\Xcal$ endowed with a positive kernel $\kappa$, which translates naturally into kernels between histograms or clouds of points. We first cover the case wher
Using Claim 1, we observe that [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], where [sigma](M) denotes the spectrum of the Gramian matrix M as an operator on [l.sup.2]. In this case, the Gramian matrix M is a convolution operator, having some sequence a as kernel. Explicit loca...
