关于分类问题的乘积规则

On the Product Rule for Classification Problems

New York University(纽约大学)

Marcelo Cicconet

摘要:

我们讨论了理论方面的产品规则的分类问题,在监督机器学习的情况下,结合分类器。我们证明了:(1)乘积规则源于MAP分类器假设等价先验和条件独立性,(2)在一定条件下,乘积规则等价于最小化与不同特征相关的类到各自中心的平方距离之和,这种距离由类的分布加权;(3)在一定的假设条件下,乘积规则等价于特征向量的连接。

英文摘要:

We discuss theoretical aspects of the product rule for classification problems in supervised machine learning for the case of combining classifiers. We show that (1) the product rule arises from the MAP classifier supposing equivalent priors and conditional independence given a class; (2) under some conditions, the product rule is equivalent to minimizing the sum of the squared distances to the respective centers of the classes related with different features, such distances being weighted by the spread of the classes; (3) observing some hypothesis, the product rule is equivalent to concatenating the vectors of features.
