另外一些常见的学习类型不是被设计用于为输入创建分类,而是作出决定;它们统称决策问题。
The other common type of learning is designed not to create classifications of inputs, but to make decisions; these are called decision problems.
同样地,当你的大脑从真实世界的传感器上获取持续的输入时,大脑迅速学习将它映射到一种第六感中。
Similarly, when you're brain gets consistent input from a real-world sensor, it quickly learns to map that into a sort-of six sense.
如果通过算法作出的决定需要输入别的地方,这时分类学习是必要的。
Classification learning is often necessary when the decisions made by the algorithm will be required as input somewhere else.
