Abstract: A method for inferring, without supervision, information about a data set and/or recognizers that are operated thereon. The recognizers are modules that are capable of analyzing, interpreting and labeling raw data of the data set with a label, which is a cognitive or substance-based identifier of the data, for instance, identifying peaks, troughs, patterns and trends of particular significance. The method infers the information about the data set and/or the recognizers based on the observable outputs of each recognizer and a mathematical means of reconciling the agreement/disagreement of the outputs. The method operates without need for knowledge of the correct label to be applied to the data set by each of the recognizers, such as a test set or prior knowledge of the accuracy of the recognizer.
