Accelerated Stochastic Zeroth-Order Quasar-Convex Optimization
Eméric Gbaguidi, Julien Hermant
We consider unconstrained minimization of smooth quasar-convex functions when only noisy function evaluations are accessible through a stochastic zeroth-order oracle. For these non…

On the SAGA algorithm with decreasing step
Luis Fredes, Bernard Bercu, Eméric Gbaguidi
Stochastic optimization naturally appear in many application areas, including machine learning. Our goal is to go further in the analysis of the Stochastic Average Gradient Acceler…
