2 线性代数(Linear Algebra)(上) 2.1 线性方程组 2.2 矩阵 2.3 线性方程组的求解 2 线性代数(Linear Algebra)(上) 在形式化一些直观概念时,常见的方法是构造一组对象(符号)和一些操作这些对象的规则。这就是所谓的代数(algebra)。线性代数是研究向量以及使用某些确定的规则来操作向量的一门学科。
【机器学习的数学基础】(一)线性代数(Linear Algebra)(上) 2 线性代数(Linear Algebra)(上+) 2.3 线性方程组的求解 前面我们介绍了方程组的一般形式,即: 其中 , 为已知常数, 为未知量, 。到目前为止,我们看到矩阵可以作为一种简洁的方法来表达线性方程组,这样我们可以将线性方程组写成 。此外,我们...
线性方程组可以写成通式 Ax=b 。 2.3.1 Particular and General Solution 若通式中的矩阵 A 前 a 列(a<=n)是单位矩阵,求解这类特殊方程组可分为三步: 寻找特解。只考虑前 a 个xi,其余 xi(i>a)皆取0。 寻找所有 Ax=0 的解。将 A 中其后的每一列表示成前 a 列之和,即得此列之解。显然,此解...
Linear Algebra 线性代数 和 。 在这本书中,我们讨论了向量的更一般的概念,并使用一个粗体字母来表示它们,例如:x和y。 一般来说,向量是特殊的对象:可以加在一起或乘以标量来产生另一个同类对象。 从抽象的数学观点来看,任何满足这两个性质的对象可以看作是一个向量。 以下是此类向量对象的一些示例: 几何矢量。
