ABSTRACT:
A method and apparatus modifies one or more weights or other numbers used to rank or score objects in order of predicted similarity to a target object. If the object most similar or identical to the target object is not ranked first, the weight or other number used to rank or score the objects is adjusted based on the objects ranked or scored higher than the most similar object, the object ranked or scored most similar to the target object, and the number of changes in direction, either positive or negative, of the current and prior adjustments to the weight or other number.
