Patent ID: 8255354

Claim:
A method of determining the probability that sampled data, associated with a source and obtained from a plurality of data input sources, are from a known source, given prior observed data obtained by the plurality of data input sources for one or more known sources, the method comprising the steps of: a) calculating probability density functions for each known source for the sampled data being associated with that source and/or calculating probability density functions for the sampled data being associated with none of the known sources using the data and the prior observed data; b) calculating a first set of probabilities that the sampled data is associated with at least one of the known sources or none of the known sources using a predetermined prior probability and the probability density functions from step a); and c) calculating a subsequent set of probabilities that the data is associated with at least one of the known sources or none of the known sources using the probabilities calculated in the step b) and the probability density functions from step a) calculated from the sampled data: wherein the prior observed data is mathematically manipulated to reduce noise or adjust the baseline.
