Comparison of the clustering quality between CBR with expert supplied weights and CBR with equal weights
| 0.1 | 0.2 | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 | 0.8 | 0.9 | 1.0 | |
|---|---|---|---|---|---|---|---|---|---|---|
| Quality is evaluated as the difference in recall and accuracy of the two techniques where positive numbers indicate better performance. The results indicate that CBR performs better when attributes used in matching are weighted by experts to signify the contribution of an attribute to the clustering decision. The asterisks indicate that no cases were retrieved that were above the listed matching thresholds. | ||||||||||
