A First Analysis of the Stability of Takens' Embedding
Han Lun Yap, Armin Eftekhari, Michael B. Wakin +1
Takens' Embedding Theorem asserts that when the states of a hidden dynamical system are confined to a low-dimensional attractor, complete information about the states can be preser…
Discrete and Continuous-time Soft-Thresholding with Dynamic Inputs
Aurele Balavoine, Christopher J. Rozell, Justin Romberg
There exist many well-established techniques to recover sparse signals from compressed measurements with known performance guarantees in the static case. However, only a few method…
Convergence Speed of a Dynamical System for Sparse Recovery
Aurèle Balavoine, Christopher J. Rozell, Justin Romberg
This paper studies the convergence rate of a continuous-time dynamical system for L1-minimization, known as the Locally Competitive Algorithm (LCA). Solving L1-minimization} proble…
Convergence and Rate Analysis of Neural Networks for Sparse Approximation
Aurèle Balavoine, Justin Romberg, Christopher J. Rozell
We present an analysis of the Locally Competitive Algorithm (LCA), a Hopfield-style neural network that efficiently solves sparse approximation problems (e.g., approximating a vect…
