Machine Learning - Linear Algebra 矩阵 从代码的角度上来讲可以看作二维数组,形如 矩阵的维度 矩阵维度=#rows * #cols,(1-1)是一个4*5的矩阵 元素坐标 Aij= ithrow && jthcol 向量 n * 1的矩阵就是向量,如下就是4维向量 向量坐标表示:Yi= ithrow...
2 线性代数(Linear Algebra)(下) 2.7 线性映射 下面,我们将研究向量空间上结构不变的映射,这将允许我们定义坐标的概念。之前我们说过向量相加并乘以标量得到的对象仍然是一个向量。这里我们希望在应用映射时保留此特性: 考虑两个实数向量空间,V,W。对于x,y∈V和λ∈R,映射Φ:V→W保持向量空间结构不变需满足: ...
