In this exercise, you are required to use support ...

In this exercise, you are required to use support vector machines (SVMs) to prediction incident duration. By this assignment on SVMs, you can get deep understanding of how to use SVMs. The data comes from the national incident management center for towing operations. These data were provided by towing officers, police and Rijkswaterstaat road-inspectors who perform incident handling. The data was collected from 1st May to 13th September 2005 on the region of Utrecht. You can find 1853 registrations of incident in total in the incidentduration.csv. Test_set.csv extract 50% of data and is used to test SVM, while train_set.csv contains the remaining and is used to train SVM. Attributes includes as follows: 1. Incident type (Stopped vehicle, lost load, accident); 2. Kind of vehicles involved (passenger cars, trucks, N/A); 3. Police required (yes, no) 4. Track research (yes, no) 5. Ambulance required (yes, no) 6. Fire brigades required (yes, no) 7. Repair service required (yes, no) 8. Tow truck required (yes, no) 9. Road inspector (yes, no) 10. Lane closer (yes, no) 11. Road repair required (yes, no) 12. Fluid to be cleaned (yes, no) 13. Damage of road equipment (yes, no) 14. Number of vehicles (Involved Single, two, more) 15. Type bergings task (onb, CMI, CMV) 16. By the week (workdays, weekend) 17. Start and end time (during peek hour, off peek hour) 18. Duration (short, long) Build prediction models with SVM to complete the following tasks. A. Use train_set.csv as train data set to build a model, and test on test_set.csv. Report the accuracy of train model and test model you get. (Suggestions: In data preprocess, you can deal with independent variables which are nominal variables by using one-hot representation, so that the corresponding value of each feature is guaranteed to be 0 or 1. It is easy to implement with get_dummies(data) function in the pandas package.) B. Use incidentduration.csv to build a model using 10-fold cross validation. Report the accuracy of train model and test model you get. C. Build a prediction model again after Feature Reduction (Keep 80% variance). Report the accuracy of train model and test model you get. D: Which model gives the highest accuracy on the test set？ Why？ Give you explanation.

听力原文：M: Hi, Ms. Rowling. How old were you when you started to write, and what was your

first book？

W: I wrote my first finished story when I was about 6. It was about a small animal, a rabbit I mean, and I've been writing ever since.

M: Why did you choose to be an author？

W: If someone asked me how to achieve happiness, step one would be finding out what you love doing most and step two would be finding someone to pay you to do it. I consider myself very lucky indeed to be able to support myself by writing.

M: Do you have any plans to write books for adults？

W: My fast two novels were for adults. I suppose I might write another one, but I never really imagine a target audience when I'm writing. The ideas come first, so it really depends on the idea that grabs me next!

M: Where did the ideas for the Harry Potter hooks come from？

W: I've no idea where ideas come from and I hope I never find out. It would spoil my excitement if it turned out I just have a funny little wrinkle on the surface of my brain which makes me think about invisible train platforms.

M: How do you come up with the names of your characters？

W: I invented some of the names in the Harry books, but I also collect strange names. I've gotten them from medieval saints, maps, dictionaries, plants, war memorials, and people I've met!
