teaching evaluations...

Dear all:

 Hope you had a good (if all too short) break; I certainly did roaming the backwaters of Kerala.

I just got your teaching evaluations for the course and it looks like the course was received  well. 

Thanks to the ~75% of you who took time to provide feedback and comments; 

I will try my best to take them into account (except perhaps for the "the course is hard" variety ;-). 

[And as for the other ~25%, they should be riddled with guilt for not taking part ;-)]

 It is my somewhat quixotic custom to make the complete evaluations--warts and all--available to 

the class students for a limited time.  So, here goes:

If you have any further comments/questions you need to get off your chest, feel free to email me. Otherwise, this will likely be the last mail on this list.

Wishing you all a great new year..

The extra credit points

Here are the extra credit points 

For project extra credit, the points you got are normalized by the total for the regular project and multiplied by the weight

(so if you get 10 extra credit points on a project that is graded for 50 pts, and counts for 10% of your grade, then you get (10/50)*10 = 2 cumulative points)

The UGs got extra credit for doing the midterm at home (it was counted as 3.5 cumulative points)

The UGs also got extra credit if they did the last question on the final ( which counts for [x/100]*15  cumulative points)

The social networks extra credit homework counted for 3.5 cumulative points.

All said there were a maximum of  14 cumulative points that one could have amassed. 

This will likely be the last mail about the class cumulatives. You should be able to find your letter grades from the registrar as and when they get posted.

Wishing you all a wonderful (if all too brief) holiday season.

(hopefully) final cumulatives

Folks

 Here are the final cumulatives for the class.  They contain your final exam marks; project 3 and demo marks and a participation grade. Let us know if you find any errors anywhere

[Note that the final was graded out of 115 for grads and 100 for UG--with the answers to the paper reviews kept as extra credit portion]

I computed the regular cumulative with 5% for participation, 25% for homeworks, 30% for exams and 40% for project. I will try some other weighted averages and take the maximum among those.

I have not computed the extra credit part---given that the grading is relative, adding extra credit to the total at the outset makes extra credit "mandatory". My idea is to set the thresholds first based on regular marks and

then consider bumping your grade based on your extra credit points. 

I normally ask the students at the top of the ladder in the 494 and 598 sections to suggest grade cutoffs for their respective sections. I offer the same chance to the current two top candidates. 

(of course, this is only advisory--but does give me useful input in that the students know the comparative level of difficulty of the class).

regards

Rao

Submitting the final

Folks

 You can submit the final in hard copy by just pushing it under my door (BY 560). If you come after 8AM, the department front desk should be open and you can also submit it there telling them that it is for me.

Please don't speed on the roads on my account; +/- a few minutes is fine.

Clarification re: I.2

More than one person seems to have been confused by the word "learning"  in I.2 below. 

What I am asking is whether the information extracted by most IE (information extraction) methods are meant to be stored in RDF or OWL format.

 Semantic web has RDF and OWL standards for specifying structure. Information 

extraction aims to extract structure rather than wait for it being manually specified. Are 

current day IE approaches aimed at learning what is normally specified in RDF or in 

OWL? Why?

Re: Clarification on Qn VIII

yes both are per click.

I notice you replaced A's pay rate with per-click, did you also mean to replace B's rate with per-click?
