In this work we introduce a conditional accelerated lazy stochastic gradient descent algorithm with optimal number of calls to a stochastic first-order oracle and convergence rate $Oleft(frac{1}{varepsilon^2}
ight)$ improving over the projection-free, Online Frank-Wolfe based stochastic gradient descent of Hazan and Kale [2012] with convergence rate $Oleft(frac{1}{varepsilon^4}
ight)$.
