[]To help you practice strategies for machine learning, the following exercise will present an in-depth scenario and ask how you would act. Consider airplane pilots who’s training involves time spent in flight simulators. These flight simulators acce…

[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…
