The Jaccard index is a statistic used for comparing the similarity and diversity of sample sets. In this paper, we proposeda new similarity measure for picture fuzzy sets based on the Jaccard index.We then comparedthe proposed similarity measure with some existing similarity measures and showedthat the new similarity measure overcomes the restrictions of the existing similarity measures. Finally, we used this new similarity measure forthe data clustering problem.
