Cost-Performance Tradeoffs in Fusing Unreliable Computational Units
Mehmet A. Donmez, Maxim Raginsky, Andrew C. Singer +1
We investigate fusing several unreliable computational units that perform the same task. We model an unreliable computational outcome as an additive perturbation to its error-free…
EE-Grad: Exploration and Exploitation for Cost-Efficient Mini-Batch SGD
Mehmet A. Donmez, Maxim Raginsky, Andrew C. Singer
We present a generic framework for trading off fidelity and cost in computing stochastic gradients when the costs of acquiring stochastic gradients of different quality are not kno…
A Deterministic Analysis of an Online Convex Mixture of Expert Algorithms
Mehmet A. Donmez, Sait Tunc, Suleyman S. Kozat
We analyze an online learning algorithm that adaptively combines outputs of two constituent algorithms (or the experts) running in parallel to model an unknown desired signal. This…
Robust Estimation in Rayleigh Fading Channels Under Bounded Channel Uncertainties
Mehmet A. Donmez, Huseyin A. Inan, Suleyman S. Kozat
We investigate channel equalization for Rayleigh fading channels under bounded channel uncertainties. We analyze three robust methods to estimate an unknown signal transmitted thro…
