   SPECT is a good data set for testing ML algorithms; it has 267 instances that are descibed by 23 binary attributes

   Other results (in press): -- CLIP4 algorithm achieved 86.1% accuracy -- ensemble of CLIP4 classifiers achieved 90.4% accuracy -- Predicted attribute: OVERALL_DIAGNOSIS (binary)

2. Relevant Information: The dataset describes diagnosing of cardiac Single Proton Emission Computed Tomography (SPECT) images.
   Each of the patients is classified into two categories: normal and abnormal. The database of 267 SPECT image sets (patients) was processed to extract features that summarize the original SPECT images.
   As a result, 44 continuous feature pattern was created for each patient. The pattern was further processed to obtain 22 binary feature patterns. The CLIP3 algorithm was used to generate classification rules from these patterns. The CLIP3 algorithm generated rules that were 84.0% accurate (as compared with cardilogists' diagnoses).
