Let X be any set, and define f; \mathcal{P}(X) \rightarrow \mathcal{P}(X) by: f(A) = A^c, for all A \subseteq X. Prove: (i) f is one-to-one; (ii) f is onto. What is the inverse function f^{-1}...
我们可以把收集到的数据表示成离散函数 f:\mathbb{R}\rightarrow\mathbb{R} 使得f(x_{j})=y_{j} 对于每个 j=1,...,n, 现在我们要求出线性方程 g(x)=ax+b 去拟合函数 f(x) 。根据最小二乘法,我们希望估测值 g(x_{j}) 与观测值 f(x_{j}) 之间误差的平方和最小,即 \sum_{j=1}^{n...
