Handling Negative value due to logarithm of probabilities.
...uage Model as the
term missing from the document are smoothened with collection frequency.
I think we must try the smoothing from collection statistics if the
document term probability doesn't work(is generating negative value).
*sum(*
*i=1,...,n, if( max(log(K.Pi), 0) == 0)*
*max(max(log(K.Pcollec.i),0)*
*else*
***log(K.Pi)*
*)*
In case both doesnt work return 0 would be only option .
Moreover selecting a large enough K would be a tricky task as as no K would
be large enough since log(x) -> -inf as x -> 0
Should we approach selecting value of K by statistically, i will mean to
r...
