Adaptive Stepsizes With Certified Convergence in Distributed Gradient Tracking With Quadratic Costs
Yifan Wang, Luca Ballotta, Ruggero Carli +3
In this work, we propose an adaptive stepsize rule with guaranteed convergence for Distributed Gradient Tracking applied to scalar quadratic problems with heterogeneous curvatures.…
Beyond Bounded Noise: Stochastic Set-Membership Estimation for Nonlinear Systems
Felix Brändle, Nicolas Chatzikiriakos, Andrea Iannelli +1
In this paper, we derive a novel procedure for set-membership estimation of dynamical systems affected by stochastic noise with unbounded support. Employing a bound on the sample c…
A polynomial-based QCQP solver for encrypted optimization
Sebastian Schlor, Andrea Iannelli, Junsoo Kim +2
In this paper, we present a novel method for solving a class of quadratically constrained quadratic optimization problems using only additions and multiplications. This approach en…
Adaptive control mechanisms in gradient descent algorithms
Andrea Iannelli
The problem of designing adaptive stepsize sequences for the gradient descent method applied to convex and locally smooth functions is studied. We take an adaptive control perspect…
