Bloom analyzed the probability of such erroneous answers, called the false-positive rate, and Bloom’s analysis has appeared in many publications throughout the years.

متن کاملA study on the false positive rate of Stegdetect
In this paper we analyse Stegdetect, one of the well-known image steganalysis tools, to study its false positive rate. In doing so, we process more than 40,000 images randomly downloaded from the Internet using Google images, together with 25,000 images from the ASIRRA (Animal Species Image Recognition for Restricting Access) public corpus. The aim of this study is to help digital forensic anal...

The implementation of a number of chemical carcinogen screening programs has been accompanied by the observation that some screens might have high false-positive error rates. With designs presently used at the National Cancer Institute and historical spontaneous tumor rates based upon control animals in previous experiments, we compute upper bounds on the false-positive error rates for several ...
