Planar data classification with a hidden layer Welcome to the second programming exercise of the deep learning specialization. In this notebook you will generate red and blue points to form a flower. You will then fit a neural network to correctly cl…
自我总结: 1.编程的思维不够,虽然分析有哪些需要的函数,但是不能比较好的汇总整合 2.写代码能力,容易挫败感,经常有bug,很烦心,耐心不够好 题目: In this programming assignment you will implement one or more of the integer multiplication algorithms described in lecture. To get the most out of this assignment, your pro…
Data Compression is an approach to compress the origin dataset and save spaces. According to the Economist reports, the amount of digital dat in the world is growing explosively, which increase from 1.2 zettabytes to 1.8 zettabytes in 2010 and 2011.…
data compression可以使数据占用更少的空间,并且能使算法提速 什么是dimensionality reduction(维数约简) 例1:比如说我们有一些数据,它有很多很多的features,取其中的两个features,如上图所示,一个为物体的长度用cm来度量的,一个也是物体的长度是用inches来度量的,显然这两上features是相关的,画到上图中,近似于一条直线,之所以点不在一条直线上,是因为我们在对物体测量长度是会取整(对cm进行取整,对inches进行取整),这样的…
Please note that when you are working on the programming exercise you will find comments that say "# GRADED FUNCTION: functionName". Do not edit that comment. The function in that code block will be graded. 1) What is a Jupyter notebook? A Jupyt…
实现一个泛型的双端队列和随机化队列,用数组和链表的方式实现基本数据结构,主要介绍了泛型和迭代器. Dequeue. 实现一个双端队列,它是栈和队列的升级版,支持首尾两端的插入和删除.Deque的API如下 public class Deque<Item> implements Iterable<Item> { public Deque() // construct an empty deque public boolean isEmpty() // is the deque emp…
编程作业二 作业链接:Deques and Randomized Queues & Checklist 我的代码:Deque.java & RandomizedQueue.java & Permutation.java 问题简介 Write a generic data type for a deque and a randomized queue. The goal of this assignment is to implement elementary data struct…
