To calculate the error or loss in machine learning or regression problems, you can use the loss
function in MATLAB. The loss
function returns the misclassification error or mean squared error between predicted and actual values. Here's an example:
main.m373 chars16 lines
In the above code, we first generate sample data and create a linear regression model using fitlm
function. Then, we predict new values using the model and calculate the mean squared error between predicted and actual values using loss
function. Finally, we display the mean squared error using disp
function.
