Web: http://www.ThinkBase.com Science in Finance announces its new products RuleMiner and FuzzyControl. RuleMiner is a ActiveX program that performs data-mining on databases in Microsoft/Jet and Access format (.mdb files). The user can graphically select one table from the file to process and can determine if each field in the table is ignored, used as an input, or predicted. Predicted variables can be any simple type including real, integer, date/time or textual. RuleMiner will decide by the type or number of discrete values in the training set whether a field is categorical or continuous. RuleMiner generates first a fuzzy decision tree and then fuzzy rules in order to predict the selected field. Where categorical textual labels are provided in the training set, RuleMiner will use them in the rule. RuleMiner reserves a user selectable proportion of the contents of the database to use as a test dataset, and returns to the user, when the rule generation process has finished, a performance score for both the training and test data. The induced ruleset can be extracted for reporting purposes, but also saved in a file for use with our combined runtime and rule editor, FuzzyControl. FuzzyControl is a Fuzzy Logic Inference Engine and editor in one ActiveX package. It is unique in that each stage of fuzzy rule generation or editing is constrained to a limited set of syntactically valid choices. Editing and generating rules requires no knowledge of a language other than English and little more than mouse clicks. There is no confusion over logical precedence in FuzzyControl: clicking on any operator shows the dependant part of the rule.
