吴恩达机器学习第一周测试

Some of the problems below are best addressed using a supervised

learning algorithm, and the others with an unsupervised

learning algorithm. Which of the following would you apply

supervised learning to? (Select all that apply.) In each case, assume some appropriate

dataset is available for your algorithm to learn from.

A. Examine a web page, and classify whether the content on the web page should be considered “child friendly” (e.g., non-pornographic, etc.) or “adult.”

B. In farming, given data on crop yields over the last 50 years, learn to predict next year’s crop yields.

C. Given a large dataset of medical records from patients suffering from heart disease, try to learn whether there might be different clusters of such patients for which we might tailor separate treatments.

D. Given data on how 1000 medical patients respond to an experimental drug (such as effectiveness of the treatment, side effects, etc.), discover whether there are different categories or “types” of patients in terms of how they respond to the drug, and if so what these categories are.

A选项应该使用监督学习里的，属于分类问题
B选项也是监督学习
C是无监督学习，使用聚类算法
D是无监督学习，聚类算法

Supervised learning 监督学习：分类问题；回归问题
