Detecting Liars Heat Sensitive Camera
Detecting Liars Get ready for an avalanche of articles! You've been warned ;) US Scientists have come up with a way of detecting liars based on the rush of blood into the cheeks when someone lies. Some simplistic pattern recognition technology is used for this, but has potentially more reliability than other lie detectors... The New Scientist article mentioned below has a nice image that gets the point across. In the BBC News article, the reliability is said to be 75% to 90%, depending on whether you're detecting liars or honest people. Artificial Intelligence can boost these statistics using a technique known as bayesian networks. This has not been done to my knowledge, but it's begging for someone to do so. The idea is to combine the various estimations (lie detectors, heat sensitive cameras, human opinions) using a probabilistic model. The information is then propagated through the network using Bayes' rule, and the probability of the person being a liar is given. The structure of this bayesian network can be learnt given enough examples, which would provide much more reliable results.
