It is not very different in form from the Jaccard index but has some different properties. The function ranges between zero and one, like Jaccard. Unlike Jaccard, the corresponding difference function.

WebIt extends the Tanimoto index by two weighting variables α and β. If α and β are set to 1 then the index returns the same result as the Tanimoto coefficient. (c) Dice Index [ Similarity Comparison ] Setting α and β in the Tversky index to 0.5 returns the Dice index. Similarity Measures for Property and Activity Profiles [ Clustering ] WebCorrelation and Similarity. The concept of correlation or coherence plays an important role in signal processing. The correlation coefficient is a key parameter for investigating object detection, classification, and identification. It has been used in radar signal analyses as well as checking radar channel hardware.
