Is it possible for decision trees to split a set of data into subsets where the sum

Is it possible for decision trees to split a set of data into subsets where the sum of the entropies (weighted respectively) of each subset will be greater than the original entropy of the set?

I know its a bit contrived, but can there be a scenario where I would need to worry about negative information gain?

Or will this not be a problem and all I have to do is plug and chug and only minimize entropy after, without worrying about its relationship to entropy before?

I don't really understand op, but I am curious about this 'negative information gain'.

How would that work exactly?
>>
entropy always increases the more shit you do / add to it

so yes

The only thing that's even remotely okay about citrus is the art. Quite literally everything else is fucking dogshit.
