today I continue writing notes about measuring quality of learning. You can read my previuos artcile 1 and article 2 about measures of quality of learning. If to summarize two of those articles we have the following:
accuracy is good measure, but if samplings is unbalanced then accuracy can have great numbers, but total model will be very bad.
precision tells you how objects model a(x) can find
precision and recall work fine on unbalanced samplings
And then question arises, is it possible somehow to merge them, but not as accuracy but as something more meaningful then accuracy?
I'll decribe different ways to describe it going from worsest to better and hopefully … more
