This is an announcement for the paper "Szemer\'{e}di's regularity lemma via martingales" by Pandelis Dodos, Vassilis Kanellopoulos and Thodoris Karageorgos. Abstract: We prove a variant of the abstract probabilistic version of Szemer\'{e}di's regularity lemma, due to Tao, which applies to a number of structures (including graphs, hypergraphs, hypercubes, graphons, and many more) and works for random variables in $L_p$ for any $p>1$. Our approach is based on martingale difference sequences.
