WebFits decision trees having non-contextual multi-armed UCB bandits at each leaf. Uses the standard approximation for confidence interval of a proportion (mean + c * sqrt (mean * (1-mean) / n)). This is similar to the ‘TreeHeuristic’ in the reference paper, but uses UCB as a MAB policy instead of Thompson sampling.
