贝叶斯公式的应用

Application of Bayesian Formula

贝叶斯公式在实际中的应用非常广泛,在产品质量监测、疾病诊断、测谎仪、教学分析、安全监测等多方面都发挥着重要的作用。贝叶斯公式不仅可以帮助人们确定导致某一事件发生的最可能的原因;而且在数量上刻画了随着新信息的加入,人们对一个事物的认识如何从先验概率过渡到后验概率。本文通过具体的例子来说明贝叶斯公式的两个作用在实际生活中的应用,以期使学生更好地理解贝叶斯公式,能够学以致用,从而解决实际生活中遇到的案例。

Bayesian formula is widely used in practice,and has played an important role in product quality monitoring,disease diagnosis,lie detector,teaching analysis,safety monitoring and other aspects.Bayesian formula can not only help people determine the most likely cause of an event,but also quantitatively depict how people's understanding of a thing transits from a priori probability to a posterior probability with the addition of new information.This paper illustrates the application of the two functions of Bayesian formula in real life through specific examples,so that students can better understand the Bayesian formula and apply it to solve the cases encountered in real life.
