Figure 4
Comparing (a) ideal, (b) regular and (c) soft or fuzzy k-means clustering. Blue points are type A cells and red points are type B cells. Each scatter point represents a cell. In plot (c), the scatter point color intensity is scaled with the confidence metric for fuzzy clustering. The detected cells with low confidence metrics are barely visible. These cells are probably experimental anomalies. The cluster center is depicted by the `X' marker. |
