Like above, we first create the scaler on line 3, fit the current matrix on line 5, and finally transform the original matrix on line 6. Let’s see how this scales our same example from above: NettetWith scikit-learn, fitting 3D+ linear regression is no different from 2D linear regression, other than declaring multiple features in the beginning. The rest is exactly the same. We will declare four features: features = …
