I am trying to apply the Jaccard coefficient as customised loss function in a Keras LSTM, using Tensorflow as backend.

The IoU metric, or Jaccard Index, is similar to the Dice metric and is calculated as the ratio between the overlap of the positive instances between two sets, ...

The Jaccard index, also known as the Jaccard similarity coefficient, is a statistic used for gauging the similarity and diversity of sample sets. It was developed by Paul Jaccard, originally giving the French name coefficient de communauté, and independently formulated again by T. Tanimoto. Thus, the Tanimoto index or Tanimoto coefficient are also used in some fields. However, they are identical in generally taking the ratio of Intersection over Union. The Jaccard coefficient measure…

05.11.2019 · After initial convergence with cross-entropy, we continue training using one of the five different loss functions: CE, wCE, sDice, sJaccard and Lovász. For wCE, theory suggests that no optimal approximation w.r.t. Dice or Jaccard can be derived before training (see Sect. 2 ).
