| Tiivistelmä: | Function decomposition (hereafter as: f-d.) is a recent machine learning method developing a hierarchical structure from class-labeled data by discovering new aggregate attributes and their descriptions. It is shown that f-d. can be used to develop a hierarchical multi-attribute decision (here as: dec.) model (here as: dec-m./dec-ms.) from a given unstructured set of dec. examples. The method implemented in a system called HINT is experimentally evaluated on a real-world housing loans allocation problem and on the rediscovery of three hierarchical dec-ms. It is demonstrated that decomposition can discover meaningful and transparent dec-ms. of high classification accuracy. The effects of human interaction are specifically studied through either assistance or provision of background knowledge for f-d., and it is shown that this has a positive effect on both the comprehensibility and classification accuracy. |
