“机器学习是从人工智能的范式识别和计算学习理论中发展而成的计算机科学领域之一。机器学习先训练数据,然后研究可预测的算法。这些算法并不使用静态编程,而是通过输入的数据创建模型,从而进行预测或给出决策。”
“We have dubbed the associated results ‘No Free Lunch’ theorems because they demonstrate that if an algorithm performs well on a certain class of problems then it necessarily pays for that with degraded performance on the set of all remaining problems.(简单来说,‘没有免费的午餐’定理从数学上证明了,一种算法只是针对某一问题来说是最好的,无法适用于其他问题。)”
