Polyfeatures sklearn
Web• polyfeatures(X, degree): expands the given n ⇥ 1 matrix X into an n ⇥ d matrix of polynomial features of degree d. Note that the returned matrix will not include the zero-th power. Note that the polyfeatures(X, degree) function maps the original univariate data into its higher order powers. http://a-d-c.ca/non-linear-regression-using-python-javascript-numpy-and-tensorflow/
