ABSTRACT:
The value of an unknown variable associated with a particular hypothesis is determined by iteratively setting the variable to each of its possible values and, for each iteration, propagating the known variables and the value of the unknown variable through confluences of the model. If only one value for the unknown variable results in a consistent set of predictions for the hypothesis, the unknown variable is set to that value. If no variables result in a consistent set of predictions, then the hypothesis is deemed to be invalid.
