In classical empiricism, the truth of―"All balls are red," for example, is assessed by inspecting balls; any observation of a non red ball refutes unequivocally the proposed generalization.
在古典经验主义中，对比如“所有球都是红色的”这一真理的评价是通过观察球来进行的；任何对非红球的观察都毫不含糊地驳斥了提出的泛化论。
Notice that in the example, the more modest conclusion "some philosophy classes are hard for some students" would not be a hasty generalization.
在上述示例中，如果收缩结论，改为比较中庸的“一些哲学课对一些学生而言是困难的”，那么就不是过度的概括了。
Once a recognition problem has been formulated by a set of example objects in a convenient representation, the generalization over this set may be considered, finally leading to a recognition system.
一旦识别问题通过一组用适宜的表示方法表示的用例对象集来形式化后，于是可能就要考虑在这个用例集上的推广问题，最后才产生一个识别系统。
