coordinatewise 是什么意思?】的更多相关文章

As far as I remember, in the context of optimization, "coordinate wise" means that you are manipulating each coordinate independently with the only criterion being that it improves your objective function. So you're zigzagging instead of taking…
matlab中自带的计算距离矩阵的函数有两个pdist和pdist2.前者计算一个向量自身的距离矩阵,后者计算两个向量之间的距离矩阵.基本调用形式如下: D = pdist(X) D = pdist2(X,Y) 这两个函数都提供多种距离度量形式,非常方便,还可以调用自己编写的距离函数. 需要注意的是:pdist2返回是n*n的距离矩阵,pdist则返回距离矩阵的下三角串联形式. 下面是具体的介绍: 一.pdist Pairwise distance between pairs of object…
Competing in a data science contest without reading the data Machine learning competitions have become an extremely popular format for solving prediction and classification problems of all sorts. The most famous example is perhaps the Netflix prize.…
小结: 1.xy平面 与  直和 https://en.wikipedia.org/wiki/Direct_sum For example, the xy-plane, a two-dimensional vector space, can be thought of as the direct sum of two one-dimensional vector spaces, namely the x and y axes. In this direct sum, the x and y ax…

该文章翻译自CKKS EXPLAINED, PART 2: FULL ENCODING AND DECODING,主要介绍CKKS方案中是如何编码和解码的(如何将复数向量转成整数多项式,以及如何求逆运算) 介绍 在前一篇文章<CKKS:第1部分,普通编码和解码>中,我们了解到,要在CKKS方案中实现加密复数向量的计算,必须首先构建一个编码和解码,将复数向量转换为多项式. 这个编/解码步骤是必要的,因为加密.解密和其他机制在多项式环上工作.因此,有必要找到一种将复数向量转换成多项式的方法. 我们…
