Summary:
- A double application of a clustering algorithm was employed to subdivide the dataset.
- This approach decreased the number of informative signs and rearranged separate signs.
- Dimensionality of the feature subspace was reduced, leading to improved classifier performance.
Impact:
- Successfully decreased the number of informative signs for cerebrovascular pathology diagnosis.
- Enhanced the recognition quality of a newly designed classifier.
- Demonstrated improved diagnostic accuracy despite an increase in the number of diagnostic classes.
Abstract:
The problem to optimize decision rules and the number of informative signs for the automated diagnosis of the cerebrovascular pathology is analysed. A double application of the algorithm to subdivide the set into clusters makes it possible to decrease the number of informative counts and to rearrange separate signs thus decreasing the dimensionality of the sum dividing subspace and improving a recognition quality for a newly designed classifier even though the number of classes being diagnosed increases.
