Reference reading material relevant to the quiz is posted here. You should also try the Java Demonstrations for Boosting and SVM to get familiar with the behavior of the algorithms studied. Lastly, here are some TA-prepared Notes on some of this section's main topics that you may find helpful.

As usual, there will be TA office hours held Tuesday in 34-302, from 6:00-7:10ish pm. Bring problems. If you can't make that time, please arrange an appointment with your assigned tutorial TA to get help. Otherwise email 6034tas@csail.

Amendment: If you downloaded lab5.zip prior to 10pm today, please download the lab zip file again. or re-download tester.py. There was a bug fix, as the original tester did not package all the files needed for submission. Please be sure to check the lab Errata section for any other lab 5 related announcements.

Thursday, 11 November

There are no recitations today due to an MIT Holiday (Armistice Day). Please attend one of the Friday recitations at the same hour.

Quiz 3 has been graded and will be returned in recitations on Friday, and subsequently in tutorials, and recitations next week.

Friday, 5 November

Because of errors in the on-line solutions to the neural net question on the 2008 final, today's mega-recitation became tangled up. Accordingly, you should erase the experience from memory and work through these notes instead.

Sunday, 24 October

Lab 4 has been released. It is available from the Labs page and due the night of Friday, November 5th.

Thursday, 21 October

For last minute help with Lab 3:

  • Kendra will be holding office hours from 4:15-5:15 in w20-5 Athena Cluster.
  • Kenny will be holding office hours from 6:00-7:00 in w20-3 Coffee House (or around that area).

For any additional help, email 6034tas@csail.mit

Wednesday, 20 October

Quiz 2 has been graded and will be returned in recitations tomorrow and Friday.

Breakpoints for Quiz 2:

Thorough understanding Adequate understanding
Problem 1 Games ≥ 40 ≥ 34
Problem 2 CSP ≥ 40 ≥ 33
Overall ≥ 80 ≥ 67

Solutions have been posted.

Monday, 18 October

There will be office hours held tomorrow in 34-302, from 6:10-7:10pm. Bring problems. Quiz 2 will be held in 10-250 on Wednesday at 10am. Any notes, paper or books are allowed, as well as a calculator; no laptops or other means of communication during the exam. Here are some notes you may find of use.

Thursday, 14 October

There will be regular lecture tomorrow, the first in a series of lectures on learning, not a mega-recitation. The hour will include a minilecture on sleep, how much you need, and what happens if you don't get enough.

Wednesday, 13 October

In tutorial this week, many of you may have seen the CSP problem from from Quiz 2 of 2008. We have posted program traces of that particular problem under the three version of CSP searches we've covered in the course. This directory also contains code from lab 4 covering CSPs. You can get a head-start on lab 4 by filling in lab4.py. Doing the implementation may solidify your understanding of CSP search prior to Quiz 2.

Monday, 11 October

Students with Monday tutorials that fall on a holiday are welcome to attend any Tuesday tutorial.

Saturday, 9 October

Lab 3 on Games search is released. It is due the evening of Friday, October 22th at midnight.

Monday, 4 October

Quizzes will be returned in tutorials, then only from PHW's office.

Breakpoints for Quiz 1:

Thorough understanding Adequate understanding
Problem 1 Rule-based Systems ≥ 42 ≥ 36
Problem 2 Search ≥ 44 ≥ 37
Overall ≥ 86 ≥ 73

Solutions have been posted.

Monday, 27 September

Quiz 1 will be on Wednesday in class. It is open notes but no laptops or cell phones as usual. Additional reference material for the search and rule based systems have been posted. In addition, here are some notes the TAs have prepared. Last minute TA office hours will be held in 34-302 from 6:10-7:10pm on Tuesday. Bring problems.

Sunday, 26 September

Lab 2 on Search is released. It is due the evening of Friday, October 8th at midnight. Looking over lab 2 and working on it early may give you additional hands-on experience with search concepts, and can help you master the material for Quiz 1.

Saturday, 18 September

Lab 1 on Rule-based Systems is released. It is due the evening of Friday, September 24th at midnight. The dates for all lab releases are also available from the Labs page.

Wednesday, 15 September

If you currently still do not have a Recitations and/or Tutorials assignment please email Yuan (yks) with the times that work best for you. Even if you don't plan to attend, it's good to sign up to receive announcements and extra material from your Recitation instructors and TAs.

Tuesday, 14 September

Many of the online tester submit issues have been resolved by a recent fix to the key.py file that you are asked to download. If you have been having trouble submitting, please download a new key.py file from https://6.034.scripts.mit.edu:444/fall10/tester/ and replace the one you currently have. Please let us know if you still have problems.

Thanks to Jelle for discovering the fix!

Monday, 13 September

We have assigned you to a regular recitation if we received your form. In the usual 3.091 chaos, some forms may have gone missing. If you are not on the assignment list above, fetch a form from us on Wednesday, fill it out, and make sure it gets into the hands of a TA.

Saturday, 11 September

Your tutorial assignment is available via the link above.

We have to start over on recitation assignments because of a miscommunication with the registrar. Scheduling forms similar to the one you filled out for tutorial assignment will be handed out in Monday's lecture.

Friday, 10 September

Lab 0 is available from the "Labs" link above. It is Due Friday, September 17th.

MegaRecitation Files are available here.

Tutorial information will appear on this page over the weekend.

Thursday, 9 September

Although there are no regular recitations this week, there will be a mega-recitation in the usual 10 AM slot in 10-250. Unlike most mega-recitations, which cover quiz problems, this one is a python review.

Wednesday, 8 September

If you did not get a tutorial scheduling form, you can get one from a supply just outside Professor Winston's office, 32-151. Scheduling is proceeding, so return as soon as possible, to Professor Winston's office.

Lecture are Mondays and Wednesdays at 10 AM in 10-250. Mega-recitations occur on Fridays at 10 AM in 10-250, the same place and time slot that is occupied by lectures on Mondays and Wednesdays.

Recitations: R1 (13-5101) or R2 (13-5101) or R3 (13-5101) F1 (24-407) or F2 (24-407) or F3 (24-407)

There will not be any regular recitations this week; they will begin next week.


Python

The official language of 6.034 is Python for a variety of reasons having little to do with the strengths and weaknesses of the language. We expect a focused weekend with any of the many Python books would be adequate preparation. See, for example, the Amazon list.

Alternatively, you can follow one of the suggestions of Rob Speer, head 6.034 TA in 2008:

  • Dive into Python is a well-recommended book that is available online. It's written for experienced programmers who just don't know Python yet. It's meant to quickly take what you already know about other languages and explain how Python does them.
  • At the other end of the spectrum, the text that was used in 6.00 has been expanded into one called Think Python. It's online. It is targeted at people who have not programmed much or at all.
  • In the middle is the O'Reilly book Learning Python. MIT has a subscription to O'Reilly, so anyone with an MIT IP address can read the book online.
