Getting topN arm features in Offpolicy method

[shubh12et1062]

Is it possible to get probabilities and topN arms in other methods like DoublyRobust and OffsetTree apart from Bootstrapped TS

It's not possible to obtain probabilities because the methods are not probabilistic. It should be theoretically possible to produce top-N rankings, but it's not currently implemented.

Its possible through decision_function() to get scores of distributions across each arms. But I have observed that the mean score distribution across arms have very similar value.

I want to use linUCB (online policy) to my data.
In my case, is decision_function()'s scores mean just the expected value of fitted model (not consider confidence bound)?

@shyun46 It includes the confidence bound.
