Thanks for sticking with us!

It's not been an easy term, but we hope you've done some good learning in 6.011 (we have!). We appreciate the effort you've put in on the material, and also to stay engaged despite the challenges.

PSet 9 solutions have been posted, and we'll post some practice exams by tomorrow, for you to mull over the relevant problems. Remember that portions for the final exam this term comprise only material after the midterm portions, in Chapters 9-13, though of course this material inevitably reaches back to some parts of the earlier material – convolution, transforms and transfer functions, LMMSE estimation, etc. 

Also posted is an optional Lecture 24 on Wiener filtering examples, which you may find worthwhile to view as part of reviewing the material in Chapter 12.

Look for us in evening hours on Sunday and Monday, 6-8:30pm (we'll post the links), and try Piazza any time. Instructions for the final exam will be sent out closer to the exam.

We've enjoyed getting to know you (as much as circumstances permitted). We'll hope to see you again downstream from here if you're continuing at MIT, and otherwise all good wishes for whatever you're going on to.

Take care, be well.

Importance of today's lecture and tomorrow's recitation

I'll hope to have many of you tuned in for the Live Q&A with the Wiener filtering lecture today at 11am, but in any case please be sure to view it before recitation tomorrow, which will have practice problems related to the topic (and these will make no sense without the lecture).

Unfortunately, given the disruptions to this semester's schedule, today's won't be a typical end-of-term wrap-up lecture, but rather a "working" lecture. Material covered today and in recitation tomorrow will be on the final exam. It will be our only (but still substantial) foray into Chapter 12. You don't have a homework on this material, so the recitation problems tomorrow assume even greater significance.

(In an normal term there would have been two more lectures, following up with Wiener filtering examples, and then a wrap-up. I will post the 2nd Wiener filtering lecture for optional viewing after today's required lecture.)

Please stick with us through two more days! No evening hours this week, and the tutorial slots today and tomorrow will function as TA office hours. We'll hold evening hours this coming Sunday and Monday, plus Piazza is open for business right through.

Thanks!

No PSet 10, and other matters

Hi, everyone. We've decided that even though PSet 10 was not going to be graded, it really doesn't make sense to even have it on your plates to think about. Instead, Monday's lecture will introduce the Wiener filter, Tuesday's recitations will get you to work through some related problems, and that's what we'll expect you to be comfortable with on this topic for the final exam. (Just to close out the topic, I'll post another lecture video on Wiener filter applications after Tuesday, and you can view that at your leisure – perhaps it will help you with review of this topic, but watching it is entirely optional.)

If you didn't submit PSet 9 because you felt you weren't far enough along on that, given everything else you had due last week, feel free to submit it today or by noon tomorrow.

Tutorial hours will only run on Monday and Tuesday this coming week, but just as office hours – sign up if you plan to attend. We won't have evening hours this coming week, but will try and have them on Sunday and Monday, May 17 and 18, evenings – maybe also Saturday May 16. And we'll be responsive on Piazza right through.

I'll post a few old exams to help with your review (but keep in mind that our coverage this term may have been different – pick and choose what you want to tackle), and solutions by the end of the week.

Take care, good luck wrapping things up.

Recitations at 11am and 12pm, do attend one

We don't seem to have had more than 30 out of 55+ attending recitations. Do try and be there today and Tuesday for your last two recitations in 6.011. And I'll hope to have you in Monday's lecture too – let's finish strong!

Cheers,
George
