Abstract:A technique for optimizing neural networks, check it in? Do you know these people in the picture above? These people call themselves “The Myth Busters.” Why? They inspired us to do something similar in Paperspace. The question we need to address is whether Batch Normalization (BN) actually solves the problem of International Covariate Shift. Although […]

First, inheritance ”’ 1. What is inheritance Inheritance is a way of creating new classes. New classes are called subclasses and inherited classes are called base classes, parent classes and superclasses. Inheritance describes a “hereditary” relationship: subclasses can reuse attributes of the parent class Inheritance in Python pays attention to two points: 1. Supporting a […]
