PARAFAC contest

This year will be organised a EEM decomposition contest

Several set of EEM data (natural data, synthetic data and lab data) including specific challenge (overlap, low intensity, noise…) and each participant will blindly process the data.

The results will be compared in term of decomposition, (number and shape of component), efficiency and rapidity. Participant can use any algorithm included CP/PARAFAC.

The results of this inter comparison exercice will be the starting point of an article dealing with the inter-user decomposition, algorithm efficiency and recommendation.

will your decomposition be the best ! Decompose and play, it’s free, fun and instructive !
