What are some clever uses for Bayesian classifiers?<p>My new site, www.tweettester.com, lets you easily make your own Bayesian classifier in the form of a "Twitter test" (it classifies contents of Twitter accounts, but you can also input text).<p>My hope was that people could come up with fun tests to administer to their friends. For instance, one test is "Sex your Tweets", which attempts to guess your sex based on your recent Tweets- it's surprisingly accurate. Another test is "What politician are you most like?", trained on candidate's speeches.<p>What are some clever uses for this algorithm, beyond spam/not spam?
