在统计学中,线性回归(英语:linear regression)是利用称为线性回归方程的最小二乘函数对一个或多个自变量和因变量之间关系进行建模的一种回归分析。这种函数是一个或多个称为回归系数的模型参数的线性组合。只有一个自变量的情况称为简单回归,大于一个自变量情况的叫做多元回归(multivariate linear regression)。(来自维基...
机器学习(三) 多变量线性回归(Linear Regression with Multiple Variables) 同样是预测房价问题 如果有多个特征值 那么这种情况下 假设h表示为 公式可以简化为 两个矩阵相乘 其实就是所有参数和变量相乘再相加 所以矩阵的乘法才会是那样 那么他的代价函数就是 同

Multiple Regression is a special kind of regression model that is used to estimate the relationship between two or more independent variables and one dependent variable. It is also called Multiple Linear Regression(MLR). It is a statistical technique that uses several variables to predict the outcom...
