Fuzzy System Demonstrations

To see a demonstration of our eXtreme Rules TM intelligent data analysis component, select one of the examples below.

Stock Market Strategies
Strategies for selecting stocks are naturally expressed as rules. This demonstration illustrates the differences between fuzzy logic and binary logic in expressing and processing rules. Two parallel sets of rules are shown, one fuzzy, the other binary. Some of the important properties illustrated are:

  • Fuzzy rules are allowed to contradict, while crisp rules cannot.
  • Information is lost in binary rule processing, as the result is either true or false, while fuzzy logic preserves information, providing a result with a continuous range of values.
  • The eXtreme Rules component is a hybrid inference engine, processing rules that may have both fuzzy and binary components.

Note: This is intended as a demonstration only! We are not advising you on stock purchases. Our intent is only to illustrate characteristics of our inference engine.



Case-Based Reasoning Demonstrations

To see a demonstration of our eXtreme Cases TM intelligent data analysis component, select one of the examples below.

Bass Fishing Advisor
Fishing for largemouth bass is much more than putting a worm on a hook and waiting. It has become a sophisticated combination of art and science that challenges clever minds. Hundreds of magazine issues, dozens of books and hundreds of hours of television programming were used to build a rule-based system for advising bass fishermen on their choice of lure and technique. But this alone is not enough. Rules need to be combined with experience to account for local differences and preferences. This is an ideal application for case-based reasoning. The BassExpert site demonstrates the power of combining a rule-based expert system for general knowledge with a case-based reasoning system for adapting to local conditions. Some of the important properties illustrated are:

  • A rule-based system encodes general domain knowledge.
  • As the user records his/her fishing experiences in an on-line fishing log, this data is immediately available for adapting the advice to the particular fisherman.
  • This hybrid system is readily adapted to new domains where general rules can be formulated, and adaptation to changing experience can be exploited. Domains particularly suitable for this technology are
    • Call Centers
    • Decision Support Systems
    • Fraud Detection
    • Customer Relationship Management
