定义5.4 泰勒级数 对于一个平滑的函数 f \in \mathcal{C}^{\infty}, f: \mathbb{R} \rightarrow \mathbb{R} ( f \in \mathcal{C}^{\infty} 表示f 连续且可微无穷多次), f 在 x_0 的泰勒级数(Taylor series)定义为: \\ T_{\infty}(x)=\sum_{k=0}^{\infty} \frac{f^{(k)}\left(...
$${{{\mathcal{L}}}({{{\boldsymbol{\pi }}},\lambda )=H({{{\boldsymbol{\pi }}})-\beta \left(\sum {\pi }_{i}^{2}-R\right),$$ (3) where β is the Lagrange multiplier. Taking the gradient and setting it to zero gives the following eigenvalue equation for the extrema...

【Math for ML】向量微积分(Vector Calculus) I. 向量梯度 假设有一个映射函数为\(f:R^n→R^m\)和一个向量\(x=[x_1,...,x_n]^T∈R^n\),那么对应的函数值的向量为\(f(x)=[f_1(x),...,f_m(x)]^T∈R^m\)。 现在考虑\(f\)对\(x_i\)的梯度为:\(\frac{\partial{f}}{\...
Symbolic Math Toolbox™ currently does not support thedotorcrossfunctions for symbolic matrix variables and functions of typesymmatrixandsymfunmatrix. If vector calculus identities involve dot or cross products, then the toolbox displays those identities in terms of other supported functions instead....
