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 CLIP3 algorithm was used to generate classification rules from these patterns. % The CLIP3 algorithm generated rules that were 77.0% accurate (as compared with cardilogists' diagnoses). % % 5.
