Data Set 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).

SPECTF is a good data set for testing ML algorithms; it has 267 instances that are descibed by 45 attributes.

Predicted attribute: OVERALL_DIAGNOSIS (binary)

NOTE: See the SPECT heart data for binary data for the same classification task.

- all continuous attributes have integer values from the 0 to 100
- dataset is divided into:
-- training data ("SPECTF.train" 80 instances)
-- testing data ("SPECTF.test" 187 instances)
