数据流图(Data Flow Diagram):简称DFD,它从数据传递和加工角度,以图形方式来表达系统的逻辑功能、数据在系统内部的逻辑流向和逻辑变换过程,是结构化系统分析方法的主要表达工具及用于表示软件模型的一种图示方法。(百科) 谈谈我的一点理解 有时候我们要开发或者理解一个系统,总体的系统结构我们弄清楚了,但是细节上需要...
数据流图与计算机二级Python考试 在计算机科学中,数据流图(DFD, Data Flow Diagram)是一种视觉工具,用于表示信息如何在系统中流动。对于学习Python编程的学生,理解数据流图不仅帮助掌握数据流动的概念,也为后续的程序设计和实现打下基础。本文将通过状态图、甘特图以及实际代码示例来阐述这一主题。 数据流图的基本概念 ...

如果读者有过SIMULINK或者LabVIEW的经验的话,应该很容易联想到data flow diagram。另一方面,如果读者对当前流行的深度学习库如TensorFlow和PyTorch等了解的话,也很容易联想到这些库的核心:计算图(computation graph)。总之,可以把CGP中编码答案的个体看作是一个数据流图或者计算图。CGP的基本形式如下(来自Miller教授的PPSN...
