Introduction 介绍 Recall from the example in the previous lesson that Keras will keep a history of the training and validation loss over the epochs that it is training the model. In this lesson, we’re going to learn how to interpret these learning curves and how we can use them to guide model development. In […]
This notebook is an exercise in the Intro to Deep Learning course. You can reference the tutorial at this link. Introduction 介绍 In this exercise you’ll train a neural network on the Fuel Economy dataset and then explore the effect of the learning rate and batch size on SGD. 在本练习中，您将在 Fuel Economy 数据集上训练神经网络，然后探索学习率和批量大小对 SGD 的影响。 […]
Introduction 介绍 In the first two lessons, we learned how to build fully-connected networks out of stacks of dense layers. When first created, all of the network’s weights are set randomly — the network doesn’t "know" anything yet. In this lesson we’re going to see how to train a neural network; we’re going to see […]
This notebook is an exercise in the Intro to Deep Learning course. You can reference the tutorial at this link. Introduction 介绍 In the tutorial, we saw how to build deep neural networks by stacking layers inside a Sequential model. By adding an activation function after the hidden layers, we gave the network the ability […]
Introduction 介绍 In this lesson we’re going to see how we can build neural networks capable of learning the complex kinds of relationships deep neural nets are famous for. 在本课中，我们将了解如何构建著名的能够学习复杂关系的深度神经网络。 The key idea here is modularity, building up a complex network from simpler functional units. We’ve seen how a linear unit computes a linear function […]
This notebook is an exercise in the Intro to Deep Learning course. You can reference the tutorial at this link. Introduction 介绍 In the tutorial we learned about the building blocks of neural networks: linear units. We saw that a model of just one linear unit will fit a linear function to a dataset (equivalent […]
