证据推理在数学模型信度检验中的应用浅析

Brief Analysis on Evidence Inference in Mathematics Model Trust Testing

数学模型在解决实际问题中具有重要地位和作用。针对同一问题 ,不同的数学模型往往有不同的信度 ,有时甚至相差甚远。如何检验数学模型的信度 ,是我们经常遇到的问题。利用 Dempster-Shafer合成法则 ,给出了数学模型与经验知识的合成公式 ,它可以作为一种检验数学模型信度的可行而简便的方法。

Mathematical models play an important role in solving practical problems. Different models of the same problem often have different degrees of belief, sometimes the differences are immense. Using Dempster-Shafer rule, the formula combining mathematical models with experiments used as a feasible and convenient method for testing the degree of belief of a mathematical model is presented.
