Course 1 of 5 in the Deep Learning Specialization. Syllabus WEEK 1 Introduction to deep learning Be able to explain the major trends driving the rise of deep learning, and understand where and how it is applied today. WEEK 2 Neural Networks Basics Learn to set up a machine learning problem...
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…
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...
just seen that our artificial neuron has a lot of difficulty learning when it's badly wrong - far more difficulty than when it's just a little wrong. What's more, it turns out that this behaviour occurs not just in this toy model, but in more general networks. Why is learning so ...
Neural Networks and Deep Learning This is the first course of the deep learning specialization at Coursera which is moderated by moderated by DeepLearning.ai. The course is taught by Andrew Ng. Introduction to deep learning Be able to explain the major trends driving the rise of deep learning,...

Neural Networks and Deep Learning is a free online book. The book will teach you about: 神经网络和深度学习是一本免费的电子书籍。这本书主要教会你: (1)Neural networks, a beautiful biologically-inspired programming paradigm which enables a computer to learn from observational data ...
Deep L-layer neural network Deep neural network和shallow neural network的区别在于隐藏层的数目,以左下角的神经网络为例,它的隐藏层数目为2,总层数为3,可以记作L=3。我们通常用n[L]表示第L层的单元数目,在该网络中,n[0]=3,n[1]=4,n[2]=3,n[3]=1;用a[L]表示第L层的激活函数。 Getting your...
