有一个成语叫集思广益,指的是集中群众的智慧,广泛吸收有益的意见。在机器学习算法中也有类似的思想,被称为集成学习(Ensemble learning)。 集成学习 集成学习通过训练学习出多个估计器,当需要预测时通过结合器将多个估计器的结果整合起来当作最后的结果输出。 展示了集成学习的基本流程。 集成学习的优势是提升了单个估计...

解决方法就是进行预测之前,排除掉森林里面的一些树。首先给森林里面的每棵树随机加上一个权重,然后用一个generic algorithm 修改权重,使这些权重可以代表对正确决策的共享里面,定一个阈值,把那些权重高于该阈值的树留下来形成最终的森林 当然还有一个思路就是不再是有一群决策树组成一个随机森林,二是由大量的弱神经...
