This demonstrates an expert system which predicts a person's shoe size from their height. It shows how fuzzy-logic rules work, and is based on the tutorial by:
To avoid interrupting the flow of this page, the rules are listed on a separate page. Clicking here will bring this up on a new tab in your browser.
To run the system, first use the input field to enter a new value. The Reset button restores the field to its default value.
Once you have input your value, press the Submit button. This will send back a new page with an estimate for the output variable shoe_size, the person's shoe size in UK units.
Please note that there may be a short delay. The system generates explanations of its reasoning, and these contain a lot of graphs. Plotting them takes a little time.
