Gravitational wave detection using multiscale chirplets
Emmanuel J. Candès, Philip R. Charlton, Hannes Helgason
A generic `chirp' of the form h(t) = A(t) cos(phi(t)) can be closely approximated by a connected set of multiscale chirplets with quadratically-evolving phase. The problem of findi…
Searching for a trail of evidence in a maze
Ery Arias-Castro, Emmanuel J. Candès, Hannes Helgason +1
Consider a graph with a set of vertices and oriented edges connecting pairs of vertices. Each vertex is associated with a random variable and these are assumed to be independent. I…
Detecting Highly Oscillatory Signals by Chirplet Path Pursuit
Emmanuel J. Candes, Philip R. Charlton, Hannes Helgason
This paper considers the problem of detecting nonstationary phenomena, and chirps in particular, from very noisy data. Chirps are waveforms of the very general form A(t) exp(iλϕ(t)…
