分享27赞 晶核吧 江文奇77 我写了一个GUI的windows 强化模拟程序。之前的帖子,是基于PRD算法去模拟。 现状是全新的算法使用的是机器学习中的逻辑回归算法,由于历史样本数量有限,才1250多次强化历史记录。所以现状算法效果能保证78% 准确率。 算法类主要逻辑是:1、 数据加载与清理 2、特征工程处理 3、模型训练、搜...
I can compile and run Fortran 90 code with MKL random number generators. I come from a Fortran 77 background , and I am struggling to figure out how
