Arrhythmia (20% of outliers version#03)
Data set contains patient records classified as normal or as exhibiting some type of cardiac arrhythmia. In total, there are 14 types of arrhythmia and 1 type that brings together all the other different types. However, 3 types of arrhythmia have no data. Again, we treat healthy people as inliers and patients suffering from arrhythmia as outliers.
