Optimal Oracle Inequality for Aggregation of Classifiers Under Low Noise Condition
We consider the problem of optimality, in a minimax sense, and adaptivity to the margin and to regularity in binary classification. We prove an oracle inequality, under the margin ...

Coherence-based near-oracle performance guarantees for sparse estimation under Gaussian noise
We consider the problem of estimating a deterministic sparse vector x0 from underdetermined measurements Ax0 + w, where w represents white Gaussian noise and A is a given determin...

High-dimensional subset recovery in noise: Sparsified measurements without loss of statistical efficiency
We consider the problem of estimating the support of a vector Rp based on observations contaminated by noise. A significant body of work has studied behavior of 1-relaxations when...

Array-based GNSS acquisition in the presence of colored noise
This paper investigates the application of the Generalized Likelihood Ratio Test detector to the Global Navigation Satellite System array-based acquisition problem. We consider an...

On Optimal Frequency-Domain Multichannel Linear Filtering for Noise Reduction
Abstract—Several contributions have been made so far to develop optimal multichannel linear filtering approaches and show their ability to reduce the acoustic noise. However, th...
