Abstract:
1. A computer-based method for classifying an observation of a set of observations, the method comprising the steps of: (a) receiving the set of observations from a first time period; (b) classifying members of the set of observations as one of a first and a second type based upon a discriminative-generative model based upon observations prior to said first time period; (c) modeling a probability density of the set of observations by assigning a first set of probabilities to members of the set of observations classified as said first type and a second set of probabilities to members of the set of observations classified as said second type based upon said discriminative-generative model based upon observations prior to said first time period (d) revising said discriminative-generative model, to account for said observations from said first time period, based upon said first and said second set of probabilities; and repeating steps (a)-(d) for a time period after said first time period.
