We investigate the topological character of a Lemma of Hayman in his study of the asymptoticbehaviour near x of meromorphic functions: it turns out that the local analyticity of the functionscan be replaced by continuity. The main result is that a function f continuous in C either has x as ...
Question: iff(x)is a continuous function on[a,b], then∫abf(x)dxis a number: True or False Integrals: The integral of a real-valued functiony=f(x)on the closed interval[a,b]can be seen as the area delimited by thex-axis, the linesx=a...

由于机器学习算法是在计算机上实现的,其中许多数学方程式都表示为数值优化方法。本章描述了训练机器学习模型的基本数值方法。训练机器学习模型通常归结为找到一组好的参数。“好”的概念是由目标函数或概率模型来决定的,我们将在本书的第二部分看到这些例子。给定一个目标函数,使用优化算法来寻找最佳值。(由于我们是在R...
For an arbitrary trace class operator \(T\in \mathcal {T}_{\textrm{sa}}(\mathcal {H}_{m})\), its characteristic function \(\chi _T:\mathbb {C}^m\rightarrow \mathbb {C}\) is given by $$\begin{aligned} \chi _T(\alpha ) :={{\,\textrm{Tr}\,}}[T{\mathscr {D}}(\al...
