WebbWe’ll also create a class for our new least squares machine to better mimic the good operational nature of the sklearn version of least squares regression. We’ll then learn how to use this to fit curved surfaces, which has some great applications on the boundary between machine learning and system modeling and other cool/weird stuff.

Webb21 apr. 2024 · 1 Answer. You are correct. You need to scale the independent variables of the data to be predicted using the stddev and mean obtained from the training set. Similarly, you need to back-scale and add the mean to the prediction for the dependent variables to obtain final prediction that matches with the predict () function.
