Some equations may have the variable on both sides of the equal sign, as in this equation: 4x−6=2x+104x−6=2x+10.To solve this equation, we need to “move” one of the variable terms. This can make it diffic
Let f be some function so that f(θ0,θ1) outputs a number. For this problem,f is some arbitrary/unknown smooth function (not necessarily the cost function of linear regression, so f may have local optima).Suppose we use gradient descent to try to minimize f(θ0,θ1)as a function o...
在机器学习之单变量线性回归(Linear Regression with One Variable)我们提到过的线性回归中,我们只有一个单一特征量(变量)——房屋面积x。我们希望使用这个特征量来预测房子的价格。我们的假设在下图中用蓝线划出: 不妨思考一下,如果我们不仅仅知道房屋面积(作为预测房屋价格的特征量(变量)),我们还知道卧室的数量、楼...

Linear Equation of One Variable An equation of one variable where the variable have unit power is called a linear equation. Example: 2x-3=8 and 3x-10=0 are both linear equations. 2x2=8 and 3x+x=14 are not linear equations. Remember: In linear equation there is no square, square root...

I know how to solve linear equations with one variable. Here I've got two. Can I get rid of one of these variables in the system, just as I'd have gotten rid of the −6 in the equation? Looking at the system of equations they've given me, I see that I've got a +y in ...
