这节里用代码演示一遍 Neural Networks and Deep Learning 这门课的核心思想,具体例子使用 Coursera 这门课 L 层 Neural Network 的例子。 可运行的源代码可以从这里下载: github.com/kakage/Deep-Learning 这里我们建造一个 L 层 Neural Network 的模型去判断图片是猫还是不是猫。 这个Neural Network 的结构如下...
5 - L-layer Neural Network Question: Use the helper functions you have implemented previously to build an $L$-layer neural network with the following structure:[LINEAR -> RELU]$\times$(L-1) -> LINEAR -> SIGMOID. The functions you may need and their inputs are: def initialize_parameters...
Code for Improving Deep Neural Network with Multiple Parametric Exponential Linear Units, arXiv:1606.00305 The main contributions are: A new activation function, MPELU, which is a unified form of ReLU, PReLU and ELU. A weight initialization method for both ReLU-like and ELU-like networks. If ...

You have previously trained a 2-layer Neural Network (with a single hidden layer). This week, you will build a deep neural network, with as many layers as you want! In this notebook, you will implement all the functions required to build a deep neural network. In the next assignment, ...
第四周编程作业(一)-Building your Deep Neural Network: Step by StepBuilding your Deep Neural Network: Step by 神经网络深度学习python Building your Deep Neural Network: Step by Step Welcome to your week 4 assignment (part 1 of 2)! You have previously trained a 2-layer Neural Network (with ...
The Deep Neural Network Demo Program I used Notepad to write the demo program. I like Notepad but most of my colleagues prefer one of the many excellent Python editors that are available. The free Visual Studio Code editor with the Python language add-in is especially n...
In the sections that follow, I explain how the DNN input-output mechanism works and show how to implement it. The demo program is coded using C#, but you shouldn’t have too much trouble refactoring the code to another language, such as Python or JavaScript, if you wish to do...
This article assumes you have a basic understanding of the neural network input-output mechanism and at least intermediate level programming skills. The demo program is coded using C# but you shouldn’t have too much trouble refactoring the demo to another language such as Python or Java if y...
