Labels:text | diagram | line | black and white | parallel OCR: Figure 2: Too few clusters: Discovered clusters will be forced to cover more than one true cluster in the data. In this case, four discovered clusters are spread over five true clusters. Three of the discovered shapes (Inverted V, V, and Ramp Down) appear the same as when using five clusters and one discovered shape is built out of examples from two distinct "real" shapes (Flat and Ramp Up), resulting in an "averaging" effect.
