Investigating the Accuracy of Thermal Infrared Lie-Detector Using Pattern Recognition

Abstract


This thesis reports the results of using feature selection techniques (e.g. attribute selection using information gain, Discretization of data, Priniciple Component Analysis) on the classification accuracy of a Thermal Infrared Lie-Detector. We use several multivariate classification techniques like Bayesian Classification, Decision Table etc. for deception detection among human subjects.

The results of this thesis show that the discretization of the data is an important step towards attaining high accuracy in this particular classification problem. We noticed an increase in classification accuracy and a decrease in classification time as a result of attribute selection methods. Overall, our goal is to statistically reduce the impact of the noise in data on classication accuracy.
