It's over! You can examine your graded final and get your final grade in Patrick's office (32-251) after noon, Tuesday, December 19, and through IAP.
 
-
By institute rule, you cannot take your final away from the office.  Alternatively, you can learn your grade in a few days via WEBSIS.
 
-
You cannot get your grade any other way.  By institute rules, we cannot
+
=== September 5, 2007 ===
-
give out grades by email or by telephone, nor can we post grades.  In particular, if
+
-
you go to the Undergraduate Office, and ask for your grade, you will
+
-
drive the normally kind, courteous, and helpful <b>Anne Hunter crazy
+
-
with rage</b>, which will be <b>viciously directed at the 6.034 staff</b>.
+
-
The TAs have finally gotten around to writing the hidden tester for [[Problem set 5]]. You should receive grades shortly.

Luis Ortiz will hold office hours in the student street near 32-123 at 11-1 tomorrow, Saturday.  Final review 32-123 at 1+.  Old quizes are like to be available in same area at 12-1.
+

=== December 13, 2006 ===
+
-
 
+
-
There remains some confusion about how we are computing grades.  Read this to be sure you are not among the confused.
+
-
 
+
-
The maximizing operator we propose to use will recognize topic areas corresponding to the
+
-
four quizes, not the problems that appeared on the quizzes.  Thus, for example, if you
+
-
did great on the SVM problem and horrible on the boosting problem, you still need to do
+
-
"thorough understanding" level work on the entire section of the final corresponding to
+
-
Quiz 4 to get an A for that topic area, not just the boosting part (presuming that topic
+
-
area 4 is again represented by SVMs and boosting).
+
-
 
+
-
If you are well inside the thresholds we established for a quiz, and you are satisfied
+
-
with where you are, it will do absolutely no harm to ignore the corresponding section
+
-
of the final completely.
+
-
 
+
-
The performance of other students does not matter as there is no curve.  If you elect to ignore part of the final, it does not matter how the people who work on that part perform; it does not matter if they all get 0 or all get 100 as far a your score is concerned (that is, the quiz threshholds, once set, are never adjusted).
+
-
 
+
-
We will fit a curve to the quiz grades that flattens out by the time you
+
-
are four or five points from a boundary.  Thus, if you are right on the upper
+
-
boundary, you get a 4.5 for that topic area; if you are five points above the upper
+
-
boundary, you get a 5.0; if you have 100 on an exam, you still get 5.0.
+
-
 
+
-
If you are close to a threshold, it could pay and cannot hurt to have another go at the material.  Suppose, for example,
+
-
that you were just a hair above the upper threshold on all the quizzes; you would have a 4.5 + epsilon for those, but if you
+
-
end up in the middle of the B range on part 5 or got a B in the homework/tutoral dimension of the subject, then the B or Bs might drag you below a 4.5 GPA.
+
-
 
+
-
Topic areas are roughly defined by the quizes and precisely defined, inclusively, as
+
-
follows:
+
-
 
+
-

There will be no tutorials this week.  Enjoy the upcoming long weekend.
+

+
-
=== November 15, 2006 ===
+
-
There <b>will be</b> a megarecitation this week, focused on support vector machine problems.
+
-
=== November 14, 2006 ===
+
-
As a reminder, Quiz 3 will be held tomorrow, Wednesday, November 15, from 11:05AM -11:55AM, in 32-123, where the lectures are held.  Past exams can be accessed
+
-
[http://courses.csail.mit.edu/6.034/Fall/Examinations/ right here].
+
-
 
+
-
=== November 13, 2006 ===
+
-
There will be an open session tonight, Monday, at 7:00 pm in 32-123, in connection with the material to be covered on Wednesday's quiz.  Not much will be presented; the purpose is mainly to answer questions and clear up confusions. 
+
-
=== November 10, 2006 ===
+
-
The calendar now provides access to revised neural net notes that are believed to be much clearer than the previous notes.  These new notes focus on relating the weight-adjustment formulas to neural net diagrams.
+
-
 
+
-
=== November 8, 2006 ===
+
-
Because Friday is a holiday the megarecitation, has become a quiz review, and will be held on Thursday, November 9, at 7pm, in 32-123.
+

+
-
=== November 7, 2006 ===
+
-
[[Problem set 4b]] is released.  It is due in one week.
+
-
 
+
-
=== November 6, 2006 ===
+
-
 
+
-
[[Problem set 4a]] mistakenly included a neural net problem in
+
-
ps4.scm, called "question 3", which you are to ignore.
+
-
 
+
-
Part 4b, which focues on neural nets, will be released this afternoon.
+
-
It does not involve any coding.  It will be due November 14th, the night
+
-
before the quiz.  We thought it important to add 4b to 4a because it is
+
-
highly likely that the next quiz will have a neural net problem.
+
-
 
+
-
[[Problem set 4a]] has been updated with a new, more accurate public tester.
+
-
 
+
-
=== November 2, 2006 ===
+
-
'''[[Problem set 4a]]''' is released, due Wednesday, November 8.  Expect a part b in the next day or two.
+
-
 
+
-
=== October 27, 2006 ===
+
-
==== Problem set 4 postponed!  No Mega-Recitation tomorrow! ====
+
-
 
+
-
Take a break -- you've earned it. There is no problem set this week.
+
-
 
+
-
Tutorials on Monday will cover various topics that aren't represented in the problem sets.
+
-
 
+
-
There is also no mega-recitation this week.
+
-
 
+
-
==== Problem set 3 ====
+
-
Problem set 3 was re-graded. The original hidden tester had a flawed test case, and also didn't catch large problems with alpha-beta search. Updated grades have been sent out. (If you submitted late, your problem set hasn't been graded yet.)
+
-
 
+
-
The problem set was scored out of 105, to reflect the 5 points from the game heuristic problem that were difficult to earn. The highest score was 102. Congratulations to all who earned that score by winning 7 out of 10 games.
+

[[Problem set 2]] is out. It's due Wednesday, October 4.
+
-
 
+
-
We've now written up a [[problem set grading policy]], which tells you things like:
+
-
* How to submit a problem set late (for a 25% penalty)
+
-
* What GraderBot does
+
-
* Why you should run the tester and make sure it runs successfully before you submit

There is no mega-recitation this week.

-
 
+
-
You can pick up your graded quizzes in your recitation on Thursday or Friday, or at Prof. Winston's office (32-251).
+
-
 
+
-
=== September 26, 2006 ===
+
-
Tutorial hours will be held on Tuesday this week.  Monday was a student holiday so Monday students can go to ANY Tuesday tutorial they can make.  The tutorials will be a quiz review for Wednesday's quiz.  Bring questions about material you're unsure about.
+
-
 
+
-
The exam will cover the material learned so far in the course, which can be found at [[Calendar]].  Exam questions are quite like what you've seen in mega-recitation and tutorials.  Past exams can be accessed
+
-
[http://courses.csail.mit.edu/6.034/Fall/Examinations/ here].
+
-
 
+
-
The terminology has changed over the past several years, and no previous 6.034 class has been in this format with four quizzes, so the mega-recitation still provides the best example problems for quizzes.
+
-
 
+
-
In particular, we will not use the terms "trigger" and "visited list" this year, the quiz will be shorter than previous years' Quiz 1, and it will of course only cover topics we've covered in the class so far.
+
-
 
+
-
=== September 25, 2006 ===
+
-
Reminder: There will be an in-lecture quiz on Wednesday,September 27.  As always in 6.034, the quiz will be open book and open notes; bring anything you want within reason.  Laptops are not considered within reason.
+
-
 
+
-
=== September 22, 2006 ===

-
[[Problem set 1]] has been graded, and the grades were e-mailed out by GraderBot. If you haven't received any grade e-mails yet, we might not know you're in the class, so [mailto:6.034-tas@mit.edu e-mail the TAs].

The [http://web.mit.edu/6.034/psets-f06/ps0 solutions to pset 0] and [http://web.mit.edu/6.034/psets-f06/ps1 solutions to pset 1] have been released.
+
-
 
+
-
=== September 19, 2006 ===

An erratum has been added to [[Problem set 1]], clarifying some inconsistency in the use of the word "trigger".

+
-
Grades for PS0 have been e-mailed out.

Some notes about the structure of 6.034:

Quizzes and evaluations

There will be 4 in-class quizzes.

The final will be organized into parts corresponding to the quizzes. If you have a bad day on one of the quiz days, you can make up for it on the final, as we propose to give you the higher of the two grades.

All quizzes and the final are open book, open notes, open problem sets and solutions, open everything, except for computers.

Tutorials and recitations

As in previous years, we will have tutorials on Mondays and Tuesdays and recitations on Thursdays and Fridays. In addition, there is a "megarecitation" to be held 11–12 on Fridays. Roughly, the purpose of each element is as follows:

Element Purpose
Lectures: To introduce most of the material and provide the big picture
Tutorials: To provide help with the homework and assess understanding
Mega recitation: To demonstrate how to work problems of the kind that tend to show up on the quizzes
Regular recitations To introduce some of the material, answer questions, provide additional

perspective, and be a venue small enough for discussion

Times and places of recitations and tutorials

We will ask you to fill out a schedule form in the first lecture so that we can make assignments. Ignore the times listed by the registrar.

There will be no tutorials, regular recitations, or megarecitation during the first week of class, the week of September 3.
