Geneticselectioncv 参数
Webmax_fun int, default=15000. Only used when solver=’lbfgs’. Maximum number of function calls. The solver iterates until convergence (determined by tol), number of iterations reaches max_iter, or this number of function calls.Note that number of function calls will be greater than or equal to the number of iterations for the MLPRegressor. Web1、初始化种群,我们需要知道,种群包含的个体称为染色体,这个染色体上的每一个片段都被称为一个基因,一条染色体对应了目标问题的一个可行解,以超参数优化为例,一条染色体就是一组超参数,而超参数组合中的 …
