WebThese results reveal insights on the trade-off between regret expectation and regret tail risk for both worst-case and instance-dependent scenarios, indicating that more sub-optimality and inconsistency leave space for more light-tailed risk of incurring a large regret, and that knowing the planning horizon in advance can make a difference on alleviating tail risks. Web1 For a positive random variable X and all δ ≥ 0, I have a tail bound of the form: P ( X > a + b δ) ≤ e − δ where a, b > 0. I want to upper bound E [ X]. Usually I would use the following identity for positive random variables: E [ X] = ∫ 0 ∞ P ( X > x) d x flights el paso to san francisco
