Bayesian decision theory selects the action a* that minimizes expected loss, i.e., a* = argmin_a E[L(θ, a)|x], where the expectation is taken with respect to the posterior distribution p(θ|x).

UnverifiedThe core idea of the product betting martingale is to choose a predictable betting function such that the expectation of the product martingale does not exceed 1, and then apply Ville's inequality to obtain that the probability of exceeding 1/α is at most α.78% similarUnverifiedExpectiles are defined by asymmetrically weighting the squared loss: the solution to minimizing E[w_τ(Y−θ)²] is the τ-expectile, where the weight w_τ is τ when Y>θ and 1−τ otherwise.71% similarUnverifiedGradient descent computes the partial derivatives of the loss function with respect to model parameters and updates the parameters in the direction opposite to the gradient to approach the minimum of the loss function.71% similarUnverifiedThe weight update formula in AdaBoost derives from the step-by-step minimization of the exponential loss function L=Σ_i e^(-y_i F(x_i)).71% similarUnverifiedThe Kelly formula is used to calculate the optimal bet proportion when the win rate and odds are known, and its core conclusion is that even with positive expectation, one should not stake all of one's capital.68% similar
