Now supporting cost-sensitive modeling!

Features of version X 5.4 (Mac OS X only)

• [new] Platinum edition now supports table dimensions of up to 30,000 rows and 30,000 columns;
• [new] Built-in cost-sensitive modeling for both classification and regression models according to a given cost-benefit matrix and an accepted target uncertainty; this allows self-organization of predictive, cost-optimized models;
• [new] Enhanced and extended AppleScript support for building models and their workflow integration;
• [updated] Tutorial and documentation;
• [updated] MS Excel model export v.1.1.2;
• [updated] TransformModel version 1.0.10;

Selected features of previous versions (Mac OS X only)

• [new] improved significance testing during model self-organization to avoid using non-relevant inputs in a model;
• [new] special time limited educational price for the Platinum version. Discover knowledge in your data and publish on our site;
• [new] automated fuzzy model based defuzzification implemented, which simplifies use of fuzzy models;
• [new] defuzzification model self-detects if related fuzzy models are available and takes their outputs for back-transforming results into the initial data space;
• [new] works on both static and dynamic fuzzy models;
• [new] article on the problem of modeling ecotoxicity added;
• [new] new article on commodity price prediction added to the publications area;
• [new] extended model evaluation features for Platinum users (works also in demo);
• [new] decomposition of the overall model error into bias, regression slope, and random disturbances contributions;
• [new] detection of worse described output values;
• [new] detection of high leverage input vectors in both modeling and prediction phases;
• [new] marks high leverage input vectors in line and scatter plots;
• [updated] improved Analog Complexing pattern recognition algorithm; detection and handling of constant target patterns;

General features of version 5.0 (all supported platforms)

• for the first time, integrated noise filtering characteristics for a second level, on-the-fly model validation; supports evaluation if a model reflects a causal relationship or if it just models noise;
• explicit definition of exogenous variables for creation of systems of equations;
• two new data mining algorithms: Analog Complexing based clustering and classification (n classes);
• extended table dimension for up to 30,000 rows;
• program-to-program communication via AppleScript (Mac only):
  • creating and predicting GMDH, Fuzzy, and AC models from within a script;
  • allows for knowledge discovery workflow processing;
  • executable sample script for demand prediction included: importing data from databases (FileMaker or AppleWorks) or spreadsheets (MS Excel), data preprocessing, data mining using different technologies, prediction of new data, combining of predictions, and returning a final prediction (high, mean, low) to the initial data source;
• ROC analysis to measure classification power of a model;
• 5 hours data mining service included;
• a new Platinum Edition introduced;

Included datasets and examples range from prediction of global temperature, stock market trends, medical diagnosis, failure of materials (like the Challenger Space Shuttle O-Ring), recognition of handwritten digits, Wine Recognition, national economy, to party affiliation in the US congress. The many examples included with KM show its power to work on human issues.
