进入第三周学习,回顾上周讲的logistic regression,一个输入经激活函数直接输出的neural network。 3.1 本周Andrew将加入一个hidden layer,即一个 shallow neural network。从最基本的知识开始讲解,见图1: 图1…
then tell us that∂C/∂w∂C/∂wand∂C/∂b∂C/∂bget very small. This is the origin of the learning slowdown. What's more, as we shall see a little later, the learning slowdown occurs for essentially the same reason in more general neural networks, not just the toy examp...
The first course of yours I took was on Convolutional Neural Networks (“Deep Learning p.5”, as far as I remember). Answering one of my questions on the Q&A board, you suggested I should start from the beginning – the Linear and Logistic Regression courses. Despite that I assumed I ha...
Introduction to Deep Learning What is neural network? 这里通过房价预测的例子,说明single neural network和multiple neural network。 图1 单一输入的房价预测图 如图1所示,Single neural network只有一个输入为房屋的大小,输出为房屋的价格,可以使用简单的ReLU函数进行房价的预测。用神经元来表示的形式如图2所示,这里...
