 maximum-likelihood estimator converges to an $l_\infty$-error of $.05$ for most
 graphs after having observed at least $100M$ distinct cascade-steps.
 
+We therefore used the Blocks~\cite{blocks} framework, written on top of Theano
+for highly efficient SGD routines with minimal memory overhead. By encoding a

+written as a sum of two matrix multiplications, which Theano optimizes for
