This MATLAB function plots the linear regression of targets relative to outputs.
在MATLAB中,plotregression函数用于绘制线性回归图。以下是plotregression函数的基本用法: matlab plotregression(x, y, 'name') 其中,x和y是数据点的坐标,'name'是可选的图例名称。 以下是一个示例: matlab x = [1, 2, 3, 4, 5]; y = [2, 3, 5, 7, 11]; plotregression(x, y, 'Data') 这...
This example shows how to plot the linear regression of a feedforward net. Get [x,t] = simplefit_dataset; net = feedforwardnet(10); net = train(net,x,t); Get y = net(x); plotregression(t,y,'Regression')Input Arguments collapse all targets— Network targets matrix | cell array...
1.2.3使用fminunc函数学习参数 之前我们通过梯度下降找到线性回归参数,我们写出价值函数和梯度,然后迭代采用梯度下降,这次我们不用梯度下降步骤,而是使用Matlab内置函数fminunc函数计算成本与theta参数。 fminunc是Matlab的一个优化求解器,来求无约束条件的函数极小值。在逻辑回归中我们希望通过参数优化J(theta),所以可以通过...
