I was wondering what is the difference between distance and certainty?
Initially, I used the default distance metric, which I believe is cosine, when I created the class. Then to get the scores, I tested with both distance and certainty to calculate cosine similarity.
But according to this FAQ, I need to use certainty for that.
On the other hand, I found here that the preferred way is to use distance in favor of certainty.
So, I would like to know if it is possible to calculate the cosine similarity using distance instead of certainty.
