The Golden Ratio Encoder
I. Daubechies, C. S. Güntürk, Y. Wang +1
This paper proposes a novel Nyquist-rate analog-to-digital (A/D) conversion algorithm which achieves exponential accuracy in the bit-rate despite using imperfect components. The pr…
Nonlinear regularization techniques for seismic tomography
I. Loris, H. Douma, G. Nolet +2
The effects of several nonlinear regularization techniques are discussed in the framework of 3D seismic tomography. Traditional, linear, penalties are compared to so-calle…
Iteratively re-weighted least squares minimization for sparse recovery
Ingrid Daubechies, Ronald DeVore, Massimo Fornasier +1
We analyze an Iteratively Re-weighted Least Squares (IRLS) algorithm for promoting l1-minimization in sparse and compressible vector recovery. We prove its convergence and we estim…
Analysis of boosting algorithms using the smooth margin function
Cynthia Rudin, Robert E. Schapire, Ingrid Daubechies
We introduce a useful tool for analyzing boosting algorithms called the ``smooth margin function,'' a differentiable approximation of the usual margin for boosting algorithms. We p…
