online training behaviour for missclassification

[calebebrim]

I'm making a simple search where the user can evaluate the result as useful or not.
Each time an result is evaluated I "onlineTrain" on server. If the user change its mind, is possible to change the evaluation.

The problem is that sometimes the classify function return an empty value...
Why this happend ? It looks like the online classifier is confused... ( just guessing)

Like:

birdClassifier.trainOnline({'wings': 1, 'flight': 1, 'beak': 1, 'eagle': 1}, 1); 
birdClassifier.trainOnline({'wings': 0, 'flight': 0, 'beak': 0, 'dog': 1}, 0); 

Then:

birdClassifier.trainOnline({'wings': 1, 'flight': 1, 'beak': 1, 'eagle': 1},0); 
birdClassifier.trainOnline({'wings': 0, 'flight': 0, 'beak': 0, 'dog': 1}, 1);  

It starts to being confused, obviously, and some times it does not return nothing on "classify" ...
I want to know why?

Can you give a specific code example? *--- Erel Segal-Halevi (http://erelsgl.github.io <http://erelsgl.github.io>) אראל סגל הלוי*

Dear calebebrim,
sorry for the delay. Can you upload a complete, minimal working code example, that I can run on my computer and reproduce the problem that you mention?
