Abstract :
The methods for variables selections which allows for optimal representation of objects group in the data are studied. Neural network based Boolean factor analysis is compared with two statistical methods - linear factor analysis and hierarchical clustering. It is shown that Boolean factor analysis is the best solution for binary data dimensionality reduction. Advantage of Boolean factor analysis is its nonlinearity.
