So P4 has been posted for a while. It is "optional" in the sense that your project grades will be based on your best three out of four grades. In particular, here's what will happen.
Suppose that your grades on P1, ..., P4 are a,b,c,d. (If you don't do P4, then d=0.)
Let x = [ (a + b + c + d) - min { a, b, c, d } ] / 3
Then x is your average grade on your best three projects.
We will use x as your overall project grade (i.e., since each project is weighed equally, it will be like you got a score of x on all FOUR of them).
I have a few questions.
ReplyDeleteWhen you make "wiki.sim" using "wiki.tr", there are two '0's at first. How can you get '0'? I think '0' cannot be derived if we use "cosine similarity" equation because a_w and b_w can't be 0.
If sentence length is less than 20, do we need to set the window size to the length of sentence?
You can get a zero if there are _no_ words in common between the sentences.
ReplyDeleteI completely ignored sentence boundaries when looking at "20 words".

ReplyDeleteSorry, fixed!
