Sample Complexity of Dictionary Learning and other Matrix Factorizations
Rémi Gribonval, Rodolphe Jenatton, Francis Bach +2
Many modern tools in machine learning and signal processing, such as sparse dictionary learning, principal component analysis (PCA), non-negative matrix factorization (NMF), -me…
Fundamental performance limits for ideal decoders in high-dimensional linear inverse problems
Anthony Bourrier, Mike E. Davies, Tomer Peleg +2
This paper focuses on characterizing the fundamental performance limits that can be expected from an ideal decoder given a general model, ie, a general subset of "simple" vectors o…
Convex Optimization Approaches for Blind Sensor Calibration using Sparsity
Cagdas Bilen, Gilles Puy, Rémi Gribonval +1
We investigate a compressive sensing framework in which the sensors introduce a distortion to the measurements in the form of unknown gains. We focus on blind calibration, using me…
Exact Recovery Conditions for Sparse Representations with Partial Support Information
C. Herzet, C. Soussen, J. Idier +1
We address the exact recovery of a k-sparse vector in the noiseless setting when some partial information on the support is available. This partial information takes the form of ei…
