WebJan 1, 2009 · The choice of an appropriate coefficient of similarity is a very important and decisive point to evaluate clustering, ... The Sorensen- Dice coefficient of similarity is frequently referred to as the measure of genetic similarity of Nei and Li (1979). For a given data set, the related values of Jaccard’s similarity are always smaller than ... WebDice Similarity Coefficient. Closely related to the classification accuracy measures previously described, the Dice similarity coefficient, often abbreviated as just Dice or DSC, is a measure of overlap of two structures. It was first proposed as a measure looking at species overlap in ecological studies and is named after the author [8].

WebJaccard index or Jaccard similarity coefficient, and the Dice similarity coefficient (DSC), also known as F1 score or Sørensen-Dice index. Besides that the DSC is defined as the harmonic mean between sensitivity and precision, the difference between the two metrics is that the IoU penalizes under- and over-segmentation more than the DSC.
