WebThe loss function no longer omits an observation with a NaN prediction when computing the weighted average regression loss. Therefore, loss can now return NaN when the predictor data X or the predictor variables in Tbl contain any missing values. In most cases, if the test set observations do not contain missing predictors, the loss function does not return NaN.

"Webquantiﬁcation comes from the loss function, l(θ,δ(X)). Frequentists and Bayesians use the loss function diﬀerently. 1.1 Frequentist interpretation, the risk function In frequentist usage, the parameter θ is ﬁxed and thus the data are averaged over. Letting R(θ,δ) denote the frequentist risk, we have R(θ,δ) = Eθl(θ,δ(X)). (1) " - The squared loss

WebWe want to minimize the cost function J0(X0) defined by the formula J0(x0) = n ∑ k = 1‖x0 − xk‖2. The solution to this problem is given by x0 = m, where m is the sample mean m = 1 n ∑nk = 1xk. Proof. J0(x0) = ∑nk = 1‖(x0 − m) − (xk − m)‖2 = ∑nk = 1‖x0 − m‖2 − 2(x0 − m)T ∑nk = 1(xk − m) + ∑nk = 1‖xk − m‖2 = ∑nk = 1‖x0 − m‖2 + ∑nk = 1‖xk − m‖2. The Pseudo-Huber loss function can be used as a smooth approximation of the Huber loss function. It combines the best properties of L2 squared loss and L1 absolute loss by being strongly convex when close to the target/minimum and less steep for extreme values. The scale at which the Pseudo-Huber loss function transitions from L2 loss for values close to the minimum to L1 loss for extreme values and the steepness at extreme values can be controlled by the value. The …
