Outline of Final Research Achievements

To discover knowledge from a large number of huge data sets, we invented, developed, and implemented 4 highly novel methods that integrate automatic data selection and pattern discovery. The method that discovers cluster distribution meta-patterns exhibited high recalls and precisions under difficult conditions of high noise contamination and ambiguous and mutually overlapping cluster boundaries and was proved to be time-efficient. The method that discovers directional non-zero weight meta-patterns, which is based on multi-task classification based on sparse modeling, showed its practicability on various kinds of data including facial expression data measured with Kinect. The method that hierarchically clusters linear classifiers and the method that evaluates and discovers general classification rules each holding true in its respective data set showed their effectiveness on various synthetic and real data.
