Single child wins over parent

This classification rule is applied if a parent and one of its child classes have a confidence higher than the global threshold. For this special case, the child is preferred over the parent, regardless of which class has the higher confidence. This is because the parent class is commonly used as a category that helps refine the final classification result rather than a classification result itself.

If more than one child has a confidence higher than the global threshold, the parent is not considered during the evaluation of minimum distances, unless two or more children are within the minimum distance. If more than two children have similar confidences, the Parent represents competing children rule is applied.
