Abstract
This chapter is devoted to consideration of results of experiments with decision tables from UCI Repository of Machine Learning Databases [32]. The aim of the first group of experiments is to verify 0.5-hypothesis for real-life decision tables. We made experiments with 23 decision tables. Results of 21 experiments confirm 0.5-hypothesis for reducts: under the construction of partial test, during each step the greedy algorithm chooses an attribute which separates at least one-half of unseparated pairs of different rows with different decisions.
