Exercises and Problems

Please comment on the chapter problems in terms of difficulty, clarity, and time demands. This information will help us and other instructors in choosing problems to assign in our classes.

Also, please comment on the exercises in terms of how useful they are in understanding the material.

Re: Exercises and Problems

Exercise 3.2 does not seem clear concerning the test set of size 1,000 mentioned at the end. The sentence begins "Similarly" implying that this test set becomes a data set D of size N = 1,000 to be made not linearly separable. Then you repeat the whole experiment on the new data set D.

But, because the purpose is to examing E_out, perhaps the intent is to take 1,000 points that are (very likely to be) out of sample, and evaluate w-vector vs. w-hat-vector on them.

Indeed, this is the intent in Ex 3.2. Thank you.

Re: Exercises and Problems

I've found the level of the problems to be about right. Doing them really helps one to digest the material. So far so good!

Re: Exercises and Problems

Would it be possible for you to release solutions to the exercises on this forum? It would be great to check my logic as I am doing these problems.

Re: Exercises and Problems

Exercise 3.6 was a mess. It's not that hard, but the notations are all messed up with no explanation and errors.
