I am surprised this paper received so little attention. It dramatically reduces RAM requirements for very big #statistical #generalizedlinearmodels while offering #computational speed ups ~x500. A #recommender system used it in a #neuralnetwork with #tensorflow to get substantial time & memory savings.

Languages with #array/ #tensor features should take note, as this is a serious contender to sparse matrix computations #datascience #machinelearning
