Computational intelligence methods and data understanding

چکیده
Experts in machine learning and fuzzy system frequently identify understanding the data with the use of logical rules. Reasons for inadequacy of crisp and fuzzy rule-based explanations are presented. An approach based on analysis of probabilities of classification p(Ci|X;ρ) as a function of the size of the neighborhood ρ of the given case X is presented. Probabilities are evaluated using Monte Carlo sampling or – for some models – using analytical formulas. Coupled with topographically correct visualization of the data in this neighborhood this approach, applicable to any classifiers, gives in many cases a better evaluation of the new data than rule-based systems. Two real life examples of such interpretation are

Computational intelligence methods for information understanding and information management
Information management relies on knowledge acquisition methods for extraction of knowledge from data. Statistical methods traditionally used for data analysis are satisfied with predictions, while understanding of data and extraction of knowledge from data are challenging tasks that have been pursued using computational intelligence (CI) methods. Recent advances in applications of CI methods to...
