You may be correct technically.  I&#x27;m not familiar with the formal definition of &quot;confidence intervals&quot; in statistics.  Informally we often speak of confidence as an estimate of the conditional probability P( C | x ) where C is the class returned by a classifier and x is the input.  That&#x27;s what I thought the parent comment was referring to but I may have been mistaken.<p>EDIT: For my own information what would knowing the confidence intervals tell you that P( C | x ) wouldn&#x27;t ?
