[中文翻译] 为了帮助您练习机器学习的策略, 在本周我们将介绍另一个场景, 并询问您将如何行动.我们认为, 这个工作在一个机器学习项目的 "模拟器" 将给一个任务, 告诉你一个机器学习项目像什么! 你受雇于一自动驾驶汽车公司.您负责检测图像中的路标 (停车标志.行人过路标志.建筑前方标志) 和交通信号灯 (红色和绿色灯).目标是识别这些对象中的哪一个出现在每个图像中.举例来说, 上述图则载有行人过路标志及红色交通灯. 您的10万标签图像是使用你的车的前置摄像头拍的.这也是你最关心的关于…

Learning Goals Understand what multi-task learning and transfer learning are Recognize bias, variance and data-mismatch by looking at the performances of your algorithm on train/dev/test sets [中文翻译] 学习目标 了解什么是多任务学习和迁移学习 通过在训练/开发/测试集上查看算法的性能, 识别偏差.方差和…

Gradient Checking Welcome to this week's third programming assignment! You will be implementing gradient checking to make sure that your backpropagation implementation is correct. By completing this assignment you will: - Implement gradient checking…

Learning Goals Understand the convolution operation Understand the pooling operation Remember the vocabulary used in convolutional neural network (padding, stride, filter, ...) Build a convolutional neural network for image multi-class classification…

In Week 6, you will be learning about systematically improving your learning algorithm. The videos for this week will teach you how to tell when a learning algorithm is doing poorly, and describe the 'best practices' for how to 'debug' your learning…
