DETERMINING WHETHER A HYPOTHESIS CONCERNING A SIGNAL IS TRUE

摘要

A method of detection of a recurrent feature of interest within a signal comprising: obtaining evidence, based on a signal, the evidence including a probability density function for each of a plurality of parameters for parameterizing the signal, including at least one probability density function for a parameter, of the plurality of parameters, that positions a feature of interest within signal data of the signal; parameterizing a portion of the signal data from the signal based upon a hypothesis that a point of interest in the signal data is a position of the feature of interest; determining a posterior probability of the hypothesis being true given the portion of the signal databy combining a prior probability of the hypothesis and a conditional probability of observing the portion of the signal data given the hypothesis, wherein the conditional probability of observing the portion of the signal data given the hypothesis is based at least upon: the parameterization of the portion of the signal data and the probability density function for at least one of the plurality of parameters; using the posterior probability to determine whether or not the hypothesis is true; the method further comprising: updating at least one of the probability density functions for the plurality of parameters using the parameterization of the portion of the signal data.
