Convergence of the Expectation-Maximization Algorithm Through Discrete-Time Lyapunov Stability Theory
Orlando Romero, Sarthak Chatterjee, Sérgio Pequito
In this paper, we propose a dynamical systems perspective of the Expectation-Maximization (EM) algorithm. More precisely, we can analyze the EM algorithm as a nonlinear state-space…
Dealing with State Estimation in Fractional-Order Systems under Artifacts
Sarthak Chatterjee, Sérgio Pequito
Fractional-order dynamical systems are used to describe processes that exhibit long-term memory with power-law dependence. Notable examples include complex neurophysiological signa…
Resilient Structural Stabilizability of Undirected Networks
Jingqi Li, Ximing Chen, Sérgio Pequito +2
In this paper, we consider the structural stabilizability problem of undirected networks. More specifically, we are tasked to infer the stabilizability of an undirected network fro…
Structural Target Controllability of Undirected Networks
Jingqi Li, Ximing Chen, Sérgio Pequito +2
In this paper, we study the target controllability problem of networked dynamical systems, in which we are tasked to steer a subset of network states towards a desired objective. M…
