For those people who wanted to take part in the interactive review but didn't get a chance..

Folks:
 Those of you who wanted to take part in the interactive review but didn't get a chance because
we ran out of time--please add your comments to the blog--preferaby as a response to this mail.

We will then collect those in making the acquired wisdom page for this year (it seems odd to have
acquired wisdom of only half the clas...)

thanks

Reminder: Interactive Review tomorrow..

Folks

 Just a reminder that there will be an interactive review tomorrow. You will be asked to say a couple of words
(1-2min max) about the topics/ideas that you particularly enjoyed or got bored stiff.

(If you are completely bereft of ideas, you may look at http://rakaposhi.eas.asu.edu/cse471/acquired-wisdom-031.htm
for what Fall 2003 folks said. Don't copy their opinions though ;-)

Also, please note that this is session is *not* meant for expressing your opinions on the quality of instruction/instructor.
You have the CEAS evaluations for that.

see you all tomorrow bright, chirpy and enlightened..

One last extension: Homework 4 will be accepted until Wednesday 4:30pm

I have been getting a huge number of questions on homework 4 today which makes me think
that people have only started working on it seriously today.

Since the homework covers a lot of topics I really would like for you guys to try and do some justice
to them. (That and I would hate to see people falling asleep in the last class after staying up all night today.)

So, I am going to allow people to submit homework 4 until wednesday 4:30pm.

Note of course  that  you can still submit it tomorrow and be done with it...

clarification on b and d of qn 3 (the robot question).

Several people asked for clarification as to how b and d differ.

The idea is that in "b" you only consider the question from a pure graph-theoretic
perspective (e.g., purely in terms of directroute(x,y)). Here, we don't need to consider
situation calculus at all.

In "d" you are thinking in terms of actions and effects and specific plans (so you need to consider situation calculs).

Hope this helps. (People who are still confused might want to skip b and do the rest..)

=====the problem from homework

In this exercise, we will consider the problem of planning a route for

a robot to take from one city to another. The basic action taken by
the robot is Go(x,y) which takes it from city x to city y if there is 
a direct route between the cities. DirectRoute(x,y) is true if and
only if there is a direct route from x to y; you can assume that all

such facts are already in the KB (see the map on page 63 of the text
 book). The robot is in Arad and must reach Fagaras.

a. Write a suitable logical description of the initial situation of
the robot

 b. Write a logical query whose solutions will provide possible paths
to the goal

c. Write a sentence describing the Go action

d. Write a suitable query whose answer can provide the plan for the
robot to go from Arad to Fagaras. 


e. Use resolution refutation to answer the query and output the plan.

f. Suppose the Robot was wearing a redshirt and green pants when it
was in Arad. We want it to be wearing the same dress when it reaches 

Fagaras. Explain how your answers to the parts a-e change.

Homework 4 will have more weight than normal homeworks. (it covers a large number of topics)

I would say something closer to 10%+. (Also note that there is a *required* part in homework--as part of the learning question).

Dr Rao,

 

Can you please tell me how much homework 4 will be worth in terms of percentage of the total grade? I know you don't like giving out numbers, but this would genuinely help.

 

Am I right in assuming that it would have to be lesser than or equal to about 5%, since you said there is 25% remaining credit to be earned and I am estimating the final should be at least 20%, given how much the midterm was worth.

Current cumulatives (with Project 3 and Project 4 marks thrown in--75% of the grade accounted for)

Folks
 Here--FYI--is the current cumulatives. I included the project 3 (at 7%) and project 4 (at 12%). The 5 projects thus come to 1+10+10+7+12=40pts.
Project 4 will be returned tomorrow.

Let me or the TA know if there are any discrepancies in the entered grades.

cheers
Rao

Homework 4 socket closed.. with two extra credit problems..

Folks:
 I added an additional part to the Seinfeld party problem (part I)--which is about naive bayes classifiers.

I also added the long promised dyanamic bayes net problem.

Both of these are made "extra-credit" and optional.

No more changes will be made to the homework. It will be due in class on Tuesday.

cheers,
Rao
