squared error loss function造句
例句與造句
- The James Stein estimator is a nonlinear estimator which can be shown to dominate, or outperform, the ordinary least squares technique with respect to a mean-square error loss function.
- However, loss-functions are often useful for stating optimality properties : for example, median-unbiased estimators are optimal under absolute value loss functions, in that they minimize expected loss, and least squares estimators are optimal under squared error loss functions, in that they minimize expected loss.
- A generalization of this idea to other loss functions than squared error ( and to classification and ranking problems ) follows from the observation that residuals y-F ( x ) are the negative gradients of the squared error loss function \ frac { 1 } { 2 } ( y-F ( x ) ) ^ 2.
- It's difficult to find squared error loss function in a sentence. 用squared error loss function造句挺難的
