np.linalg.norm() computes the norm of a NumPy array according to an order, ord, which specifies the metric by which the norm takes. For example, if we are given an array [
先回顾一下范数的定义(en.wikipedia.org/wiki/Norm_(mathematics)): Given a vector space V over a subfield F of the complex numbers, a norm on V is a function p: V → R with the following properties:[1] For all a ∈ F and all u, v ∈ V, p(av) = |a| p(v), (absolute ho

学卷积神经网络的理论的时候,我觉得自己看懂了,可是到了用代码来搭建一个卷积神经网络时,我发现自己有太多模糊的地方.这次还是基于MINIST数据集搭建一个卷积神经网络,首先给出一个基本的模型,然后再用Batch Norm.Dropout和早停对模型进行优化:在此过程中说明我在调试代码过程中遇到的一些问题和解决方法. 一.搭建基本的卷积神经网络 第一步:准备数据 在<Hands on Machine Learning with Scikit-Learn and TensorFlow>这本书上,用的
