Loss functions for regression 以上讨论的是分类模型的损失函数,这个部分主要讨论回归问题的损失函数 \mathbb { E } [ L ] = \iint L ( t , y ( \mathbf { x } ) ) p ( \mathbf { x } , t ) \mathrm { d } \mathbf { x } \mathrm { d } t 一般来说,我们取平方误差 L ( t , y...
Relation is established between the rate of approximating of a function by polynomials and the rate of growth of the coefficients of these polynomials depending on analytic or differential properties of these functions. It is found that our result is connected with regularization of the Ritz method ...

Linear functions are functions that produce a straight line graph. The equation for a linear function is: y = mx + b, Where: m = the slope , x = the input variable (the “x” always has an exponent of 1, so these functions are always first degree polynomial.). b = where the ...
Another way of looking at the situation is to note that if not all the coefficients p, q, r vanish, then we have a nontrivial polynomial equation of degree not exceeding 2. We can always solve such an equation and find that there are at most two solutions. Returning to the requirement...
