三种reasoning的方式 

Deductive Reasoning (演绎推理): Basically drawing a conclusion based on the data.

Inductive Reasoning (归纳推理): If something is ture for x, then it's true for x+1; if it's true for one specific case,it's true for all the cases.

                                             It creates generalizations (泛化), interpolations (插值), extrapolations(推论).

Abductive Reasoning (溯因推理):This is based on sort of the human need for meaning. 通过对数据建模（modeling）来向人们解释数据的含义。
