仿射函数基于一阶多项式构建，通常表示为 f (x) = A x + b。其中，A 为 m×k 矩阵，x 为 k 维向量，b 是 m 维向量。仿射函数实际上描绘了一种从 k 维空间映射到 m 维空间的关系。假设 f 是一个向量函数，若能表示为 f(x1,x2,…,xn)=A1x1+A2x2+…+Anxn+b，其中 Ai 可以为...

We show that every finite-dimensional Alexandrov space X with curvature\nbounded from below embeds canonically into a product of an Alexandrov space\nwith the same curvature bound and a Euclidean space such that each affine\nfunction on X comes from an affine function on the Euclidean space....

We parametrize continuous self-affine functions defined in [3] and represent them by the infinite sum. We also give a necessary and sufficient condition so that a self-affine function has absolutely continuous distribution with respect to the Lebesgue measure. Moreover we discuss surface filling ...
The paper studies the problem of computing a differentially private solution to convex optimization problems whose objective function is piecewise affine. Such problem is motivated by applications in which the affine functions that define the ... S Han,U Topcu,GJ Pappas 被引量: 36发表: 2015年 ...
We show how to achieve public-key encryption schemes that can securely encrypt nonlinear functions of their own secret key. Specifically, we show that for any constant d ε N, there exists a public-key encryption scheme that can securely encrypt any function f of its own secret key, assuming...
