Suppose your email program watches which emails you do or do not mark as spam, and based on that learns how to better filter spam. What is the task T in this setting? Classifying emails as spam or not spam. Watching you label emails as spam or not spam. O The number (or fraction) of emails correctly classified as spam/not spam. None of the above-this is not a machine learning problem.
Of the following examples, which would you address using an unsupervised learning algorithm? (Check all that apply.) Given email labeled as spam/not spam, learn a spam filter. Given a set of news articles found on the web, group them into set of articles about the same story. Given a database of customer data, automatically discover market segments and group customers into different market segments. Given a dataset of patients diagnosed as either having diabetes or not, learn to classify new patients as having diabetes or not.
You're running a company, and you want to develop learning algorithms to address each of two problems. Problem 1: You have a large inventory of identical items. You want to predict how many of these items will sell over the next 3 months. Problem 2: You'd like software to examine individual customer accounts, and for each account decide if it has been hacked/compromised. Should you treat these as classification or as regression problems? O Treat both as classification problems. O Treat problem 1 as a classification problem, problem 2 as a regression problem. Treat problem 1 as a regression problem, problem 2 as a classification problem. O Treat both as regression problems.
