INDEX How do we know if we have a good line Linear Regression Training and Loss How do we know if we have a good line So as we said before, our model is something that we learned from data.And there are lots of complicated model types and lots of int…

INDEX Introducing ML Framing Fundamental machine learning terminology Introducing ML What you learn here will allow you, as a software engineer, to do three things better. First, it gives you a tool to reduce the time you spend programming. Second, i…

Goal of training a model is to find a set of weights and biases that have low loss, on average, across all examples. —— Descending into ML: Training and Loss 注释:教程中的 loss ≠ 平均方差,而是指单个 labeled example 的方差(也就是误差 loss ),这里的 reducing loss 是指减小整体的误差(就是 MS…

1.使用 TensorFlow 的建议 Which API(s) should you use? You should use the highest level of abstraction that solves the problem. The higher levels of abstraction are easier to use, but are also (by design) less flexible. We recommend you start with the high…

Learning Goals Understand why Machine Learning strategy is important Apply satisficing and optimizing metrics to set up your goal for ML projects Choose a correct train/dev/test split of your dataset Understand how to define human-level performance U…

[]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…

在Github上也po了这个系列学习笔记(MachineLearningCourseNote),觉得写的不错的小伙伴欢迎来给项目点个赞哦~~ ML Lecture 0-2: Why we need to learn machine learning? Why we need to learn ML Many people think: Wow!!! AI is so powerful right now! You see AlphaGO? AI is going to replace human…
