You have implementedrandom_mini_batches()in the Optimization programming assignment of course 2. Remember that this function returns a list of mini-batches. Exercise: Complete the function below. The model below should: create placeholders initialize parameters forward propagate compute the cost create ...
Primitive constructs. 1.Programming language(numbers, strings, simple operators 2.English(words) Syntax句法 (which strings of characters and symbols are well- formed) 1. Programming language eg. We'll get to specifies shortly, but for example 3.2+3.2 is a valid Python expression 2. English, '...
每个数据在output layer都只有一个1,也就是one of[1 0 0 0]^T的含义 四、Programming Assignment 【图片】第一部分变成任务和week3的正则化逻辑回归表达式一致,实际上课程意思week3就用loop来做矩阵计算,week4教你向量化矩阵计算 h_theta=sigmoid(X*theta);% 5*1 ...
Welcome to your final programming assignment of this week! In this notebook, you will implement a model that uses an LSTM to generate music. You will even be able to listen to your own music at the end of the assignment. You will learn to: ...

1 Programming Project 20% final exam 60% 其中,written assignment的形式和期末考试相似度较高 另外,programming project会是python project. 最后, 这门课是double pass,期末低于40%就会按期末分计算总成绩。(少有的宽容) Lecturer professor 王伟 Consultation Time: 2-3pm, at K17 402, 推荐piazza forum提问 ...
Programming Assignment 2: Deques and Randomized Queues 原题地址:里头有具体的 API 要求和数据结构实现的性能要求。 使用泛型实现双端队列和随机队列。此作业的目标是使用数组和链表实现基本数据结构,并加深泛型和迭代器的理解。 Dequeue: double-ended queue or deque (发音为“deck”) 是栈和队列的概括,支持从...
As always, if you get stuck on the quiz and programming assignment, you should post on the Discussions to ask for help. (And if you finish early, I hope you'll go there to help your fellow classmates as well.)-- by Andrew NG ...
