我有一个 python 函数,它接受一堆(1 或 2)个参数并返回一个 2D 数组。我一直在尝试使用scipycurve_fit和least_squares优化输入参数,以便生成的二维数组与另一个预先制作的二维数组相匹配。我遇到了这两种方法都返回初始猜测作为收敛解决方案的问题。在从我的头上扯下很多头发后,我发现问题是,由于它对初始猜测的小...
Now, I want to look at one of its most practical applications: least squares fitting. In this tutorial, we’ll perform straight-line fitting and polynomial least squares fitting, both by hand and with Python.What Is Least Squares Fitting?

The determination of the optimal cutting parameters is based on the use of the Nonlinear Least-Squares Minimization and Curve-Fitting library for Python (LMFIT) whith a dual Levenberg-Marquardt optimization algorithm that has been developed... M Kaoutoing,RH Ngouna,T Beda,... 被引量: 0发表:...
The lmfit Python library supports provides tools for non-linear least-squares minimization and curve fitting. The goal is to make these optimization algorithms more flexible, more comprehensible, and easier to use well, with the key feature of casting variables in minimization and fitting routines as...
