matlab function evalclusters.m  (MathWorks Inc)

MathWorks Inc matlab function evalclusters.m
On the determination of the right number of clusters. Figures 11A, 11C and 11E misclassification error versus effect size when the correct number of clusters (five) is known and provided to the k-means algorithm (R=0.0001, 0.45 and 0.9). Number of patients P=100, 500. Number of proteins in the assay N=1129. Completely overlapping signatures, ‘among neighbors’ correlation of proteins R ij =R ∣i-j∣ . Figures 11B, 11D and 11F illustrate the situation where the correct number of clusters is not provided to the k-means algorithm but is evaluated by the <t>evalclusters.m</t> function based on the values of 4 criteria: Calinski-Harabasz, Davies-Bouldin, Gap and Silhoutte. Note that as everywhere in this paper, each point is an average of 12 simulations; therefore the optimal number of clusters is not necessary integer number. Note that Gap criterion performs much better than the rest of criteria, but even for Gap the required effect size for correct prediction of the number of clusters is substantially higher than the one required for correct classification when the number of clusters is known.

Figure Lengend Snippet: On the determination of the right number of clusters. Figures 11A, 11C and 11E misclassification error versus effect size when the correct number of clusters (five) is known and provided to the k-means algorithm (R=0.0001, 0.45 and 0.9). Number of patients P=100, 500. Number of proteins in the assay N=1129. Completely overlapping signatures, ‘among neighbors’ correlation of proteins R ij =R ∣i-j∣ . Figures 11B, 11D and 11F illustrate the situation where the correct number of clusters is not provided to the k-means algorithm but is evaluated by the evalclusters.m function based on the values of 4 criteria: Calinski-Harabasz, Davies-Bouldin, Gap and Silhoutte. Note that as everywhere in this paper, each point is an average of 12 simulations; therefore the optimal number of clusters is not necessary integer number. Note that Gap criterion performs much better than the rest of criteria, but even for Gap the required effect size for correct prediction of the number of clusters is substantially higher than the one required for correct classification when the number of clusters is known.

Article Snippet: Instead, the MATLAB function evalclusters.m was used, which calculated the values of 4 criteria (Calinski- Harabasz [ ], Davies-Bouldin [ ], Gap [ ] and Silhoutte [ ]) and made the decision on the optimal number of clusters in the given dataset based on the values of each criterion. presents the averaged results for 12 datasets simulating the ‘worst case scenario’ of overlapping biomarker signatures and ‘among neighbors’ correlation.
