Unlike supervised learning, curve fitting requires that you define the function that maps examples of inputs to outputs. The mapping function, also called the basis function can have any form you like, …

Webscipy.optimize.curve_fit¶ curve_fit is part of scipy.optimize and a wrapper for scipy.optimize.leastsq that overcomes its poor usability. Like leastsq, curve_fit internally uses a Levenburg-Marquardt gradient method (greedy algorithm) to minimise the objective function.
