The regret R_T is defined as the cumulative sum of the differences between the global optimum and the function values at the algorithm's query points over T rounds of interaction, i.e., R_T = Σ[f(x*) - f(x_t)].

UnverifiedThe moment generating function M(t) = E[e^{tX}] can be used to successively obtain the moments of a random variable by differentiating with respect to t and setting t=064% similarUnverifiedIn robust regression, replacing the Gaussian likelihood function with a t-distribution is equivalent to reducing the weight of outliers in the loss function, which improves the model's robustness to anomalous values.64% similarUnverifiedThe Rasch model (1-parameter IRT) assumes that the probability of a correct response is determined solely by the difference between the examinee's ability and the item difficulty, taking the form of a logistic function P(correct) = 1/(1+exp(-(θ-b))).59% similarUnverified在二分类问题中召回率(Recall/Sensitivity)计算公式为TP/(TP+FN),衡量模型识别所有真实阳性样本的能力59% similarUnverifiedThe study generates samples of X_{t+Δt} conditioned on X_t, allowing the network to implicitly learn the conditional distribution p(X_{t+Δt}|X_t) by training on observed segments58% similar
