1. 线性回归 回归(regression)问题指一类为一个或多个自变量与因变量之间关系建模的方法,通常用来表示输入和输出之间的关系。 机器学习领域中多数问题都与预测相关,当我们想预测一个数值时,就会涉及到回归问题,如预测房价等。(预测不仅包含回归问题,还包含分类问题) 线性回归(Linear Regression),自变量 $\textbf x$ ...

Copy Code Copy Command This example shows how to perform simple linear regression using the accidents dataset. The example also shows you how to calculate the coefficient of determination R2 to evaluate the regressions. The accidents dataset contains data for fatal traffic accidents in US states. ...
In the same cpp file there are also some tests on the Iris dataset and on the EMNIST dataset.SoftmaxA generalization of the logistic regression for the case when one has more than one output is softmax. The implementation is in Softmax.h. Because it's a particular case of generalized ...
