Theory of expected value
Webb2 feb. 2024 · Mathematically speaking, the expected value of a random variable X X is the sum of each possible value x x of X X, multiplied by the probability of that value, P (x) P (x). Have a look at the expected value formula: \small E (X) = x_1 \cdot P (x_1) + \ldots + x_n \cdot P (x_n) E (X) = x1 ⋅ P (x1) + … + xn ⋅ P (xn) Webb5 dec. 2024 · A second focus of our work is to consider alternative performance metrics, that may be more suitable than the expected sum of rewards for the practitioner. We propose a risk-aware algorithm for a bandit problem where the learner wants to find a safe arm according to a risk metric: the Conditional-Value-at-Risk.
