Abstract:
A method for determining continuous-valued hidden data from observable data, comprising the steps of:A) conductive a training stage which includes the steps of:labelling a plurality of representative sets of unaligned observed data to identify correct alignment of the observed data and continuous-valued hidden data associated with each set of observed data;analyzing the observed data to generate a first model which represents the aligned observed data;analyzing the aligned and labelled data sets to generate a second model which explicitly represents the coupling between aligned observable data and the hidden data;B) for each set of unlabelled data, conducting a labelling stage which includes the steps of:analyzing the unlabelled set of unaligned observed data by means of the first model to determine alignment of the observable data associated therewith;applying the second model to said unlabelled set of aligned observed data; anddetermining hidden data for the unlabelled set of aligned data from said application of the second model.
