Not yet an organization here, but I've used scikit-learn for my internship project and thesis.
Something I implemented during that work (barely working) was the EM algorithm. I was wondering if EM is of any interest of the library.
c = argmax_{c \in C} (log(P(c)) + Sum_i (N_{d,d_i} \times log(P(d_i|c)))
where c - best class
C - set of classes
P(c) - prior prob. of class c
P(d_i|c) - conditional of the word d_i on the class c and
N_{d,d_i} - frequency of word d_i in document d
Excuse me for the possibly weird notation.Virtually this expression means it places a frequency power upon the word probability, which is basically assuming (naively, I think) "words that are more likely to occur should be empowered".
It seems I don't have any twitter friends on Subjot, yet..
Congratulations on Subjot! I really like the idea. Are there plans for some kind of 'reputation' for people in specific subjects they talk about?
git task list
git task new "Fix homepage styling"
That can be achieved if you put something like this on .gitconfig:
[alias]
task = !tigger
