【SciPy库】scipy.optimize.fmin_l_bfgs_b进行L-BFGS优化 【时间】2020.01.07 【题目】【SciPy库】scipy.optimize.fmin_l_bfgs_b进行L-BFGS优化 具体用法参考官方文档:scipy.optimize.fmin_l_bfgs_b x,min_val,info=scipy.optimize.fmin_l_bfgs_b(func, x0, fprime=None, args=(), approx_grad=0, bou...
See Notes for relationship to ftol, which is exposed (instead of factr) by the scipy.optimize.minimize interface to L-BFGS-B. iprint (int)– Controls the frequency of output. iprint < 0 means no output; iprint = 0 print only one line at the last iteration; 0 < iprint < 99 print...
I am not insisting on keeping flaws in SciPy. This is a wrong reading of what I am saying. What you seem to not be willing to understand is that every change that we do on the public API has consequences as SciPy is used in a lot of code and people sometimes even rely on "non o...

即使世界有时表现的不那么好，也总是相信，那只是暂时状态。那些不好的状态，终究会被人们变革掉。基于这种素朴的生活信念，进入了机器学习研究领域。据此，对于机器学习系统的一个基本假设就是: 一个理想的机器学习系统，其最坏的状态不应该是该系统的稳定状态。多么幸运，这个假设确实可以用来研究软聚类算法的参数选...

Bases: qiskit.algorithms.optimizers.scipy_optimizer.SciPyOptimizer Limited-memory BFGS Bound optimizer. The target goal of Limited-memory Broyden-Fletcher-Goldfarb-Shanno Bound (L-BFGS-B) is to minimize the value of a differentiable scalar function ff. This optimizer is a quasi-Newton method, meani...
