WebStatisticians talk about the “null hypothesis”, which is that one classifier’s performance is the same as the other’s. We’re usually hoping that the results of an experiment reject the null hypothesis! This involves a certain level of statistical significance: we might reject the hypothesis at the 5% level of statistical significance ...
