P. Jung, F. Krahmer and D. Stöger. Blind Demixing and Deconvolution at NearOptimal Rate, April 2017.
[Abstract] [BibTeX]

Abstract We consider simultaneous blind deconvolution of r source signals from its noisy superposition, a problem also referred to blind demixing and deconvolution. This signal processing problem occurs in the context of the Internet of Things where a massive number of sensors sporadically communicate only short messages over unknown channels. We show that robust recovery of message and channel vectors can be achieved via convex optimization when random linear encoding using i.i.d. complex Gaussian matrices is used at the devices and the number of required measurements at the receiver scales with the degrees of freedom of the overall estimation problem. Since the scaling is linear in r our result significantly improves over recent works.

C. Kümmerle and J. Sigl. Harmonic Mean Iteratively Reweighted Least Squares for LowRank Matrix Recovery, March 2017.
[Abstract] [BibTeX]

Abstract We propose a new iteratively reweighted least squares (IRLS) algorithm for the recovery of a matrix X ∊ ℂ^(d_1× d_2) of rank r ≪ min(d_1,d_2) from incomplete linear observations, solving a sequence of low complexity linear problems. The easily implementable algorithm, which we call harmonic mean iteratively reweighted least squares (HMIRLS), optimizes a nonconvex Schattenp quasinorm penalization to promote lowrankness and carries three major strengths, in particular for the matrix completion setting. First, the algorithm converges globally to the lowrank matrix for relevant, interesting cases, for which any other (non)convex stateoftheart optimization approach fails the recovery. Secondly, HMIRLS exhibits an empirical recovery probability close to 100% even for a number of measurements very close to the theoretical lower bound r (d_1 +d_2 r), i.e., already for significantly fewer linear observations than any other tractable approach in the literature. Thirdly, HMIRLS exhibits a locally superlinear rate of convergence (of order 2p) if the linear observations fulfill a suitable null space property. While for the first two properties we have so far only strong empirical evidence, we prove the third property as our main theoretical result.

T. Hudson and M. Morandotti. Properties of screw dislocation dynamics: time estimates on boundary and interior collisions, March 2017.
[Abstract] [BibTeX]

Abstract In this paper, the dynamics of a system of a finite number of screw dislocations is studied. Under the assumption of antiplane linear elasticity, the twodimensional dynamics is determined by the renormalised energy. The interaction of one dislocation with the boundary and of two dislocations of opposite Burgers moduli are analysed in detail and estimates on the collision times are obtained. Some exactly solvable cases and numerical simulations show agreement with the estimates obtained.

J.M. Feng, F. Krahmer and R. Saab. Quantized Compressed Sensing for Partial Random Circulant Matrices, February 2017.
[Abstract] [BibTeX]

Abstract We provide the first analysis of a nontrivial quantization scheme for compressed sensing measurements arising from structured measurements. Specifically, our analysis studies compressed sensing matrices consisting of rows selected at random, without replacement, from a circulant matrix generated by a random subgaussian vector. We quantize the measurements using stable, possibly onebit, SigmaDelta schemes, and use a reconstruction method based on convex optimization. We show that the part of the reconstruction error due to quantization decays polynomially in the number of measurements. This is in line with analogous results on SigmaDelta quantization associated with random Gaussian or subgaussian matrices, and significantly better than results associated with the widely assumed memoryless scalar quantization. Moreover, we prove that our approach is stable and robust; i.e., the reconstruction error degrades gracefully in the presence of nonquantization noise and when the underlying signal is not strictly sparse. The analysis relies on results concerning subgaussian chaos processes as well as a variation of McDiarmid's inequality.

E. de Vito, M. Fornasier and V. Naumova. A Machine Learning Approach to Optimal Tikhonov Regularisation I: Affine Manifolds, October 2016.
[Abstract] [BibTeX] [arXiv]

Abstract Despite a variety of available techniques the issue of the proper regularization parameter choice for inverse problems still remains one of the biggest challenges. The main difficulty lies in constructing a rule, allowing to compute the parameter from given noisy data without relying either on a priori knowledge of the solution or on the noise level. In this paper we propose a novel method based on supervised machine learning to approximate the highdimensional function, mapping noisy data into a good approximation to the optimal Tikhonov regularization parameter. Our assumptions are that solutions of the inverse problem are statistically distributed in a concentrated manner on (lowerdimensional) linear subspaces and the noise is subgaussian. One of the surprising facts is that the number of previously observed examples for the supervised learning of the optimal parameter mapping scales at most linearly with the dimension of the solution subspace. We also provide explicit error bounds on the accuracy of the approximated parameter and the corresponding regularization solution. Even though the results are more of theoretical nature, we present a recipe for the practical implementation of the approach and provide numerical experiments confirming the theoretical results. We also outline interesting directions for future research with some preliminary results, confirming their feasibility.

[Abstract] [BibTeX] [arXiv]

Abstract We introduce an extension of cone splines and box splines to fractional and complex orders. These new families of multivariate splines are defined in the Fourier domain along certain sdimensional meshes and include as special cases the threedirectional box splines tearticle:condat and hex splines tearticle:vandeville previously considered by Condat, Van De Ville et al. These cone and hex splines of fractional and complex order generalize the univariate fractional and complex Bsplines defined in tearticle:ub,article:fbu and investigated in, e.g., tearticle:fm,article:mf. Explicit time domain representations are derived for these splines on 3directional meshes. We present some properties of these two multivariate spline families such as recurrence, decay and refinement. Finally it is shown that a bivariate hex spline and its integer lattice translates form a Riesz basis of its linear span.

M. Kech and F. Krahmer. Optimal Injectivity Conditions for Bilinear Inverse Problems with Applications to Identifiability of Deconvolution Problems, SIAM Journal on Applied Algebra and Geometry, 1(1):2037, 2017.
[Abstract] [BibTeX] [arXiv]

Abstract We study identifiability for bilinear inverse problems under sparsity and subspace constraints. We show that, up to a global scaling ambiguity, almost all such maps are injective on the set of pairs of sparse vectors if the number of measurements m exceeds 2(s_1+s_2)2, where s_1 and s_2 denote the sparsity of the two input vectors, and injective on the set of pairs of vectors lying in known subspaces of dimensions n_1 and n_2 if m≥ 2(n_1+n_2)4. We also prove that both these bounds are tight in the sense that one cannot have injectivity for a smaller number of measurements. Our proof technique draws from algebraic geometry. As an application we derive optimal identifiability conditions for the deconvolution problem, thus improving on recent work of Li, Lee, and Bresler [Y. Li, K. Lee, and Y. Bresler, Identifiability and Stability in Blind Deconvolution under Minimal Assumptions, preprint, https://arxiv.org/abs/1507.01308, 2015].

[Abstract] [BibTeX] [.pdf]

Abstract We consider the problem of estimating the curvature profile along the boundaries of digital objects in segmented blackandwhite images. We start with the curvature estimator proposed by Roussillon et al. which is based on the calculation of maximal digital circular arcs (MDCAs). We extend this estimator to the $$backslashlambda $$ λ MDCA curvature estimator that considers several MDCAs for each boundary pixel and is therefore smoother than the classical MDCA curvature estimator. We prove an explicit order of convergence result for convex subsets in $$backslashmathbb R^2$$ R 2 with positive, continuous curvature profile. In addition, we evaluate the curvature estimator on various objects with known curvature profile. We show that the observed order of convergence is close to the theoretical limit of $$backslashmathcal Obackslashleft( h^backslashfrac13backslashright) $$ O h 1 3 as $$hbackslashrightarrow 0^+$$ h textrightarrow 0 + . Furthermore, we establish that the $$backslashlambda $$ λ MDCA curvature estimator outperforms the MDCA curvature estimator, especially in the neighborhood of corners.

[Abstract] [BibTeX] [arXiv] [.pdf]

Abstract We introduce a novel constructive approach to define time evolution of critical points of an energy functional. Our procedure, which is different from other more established approaches based on viscosity approximations in infinite dimension, is prone to efficient and consistent numerical implementations, and allows for an existence proof under very general assumptions. We consider in particular rather nonsmooth and nonconvex energy functionals, provided the domain of the energy is finite dimensional. Nevertheless, in the infinite dimensional case study of a cohesive fracture model, we prove a consistency theorem of a discretetocontinuum limit. We show that a quasistatic evolution can be indeed recovered as a limit of evolutions of critical points of finite dimensional discretizations of the energy, constructed according to our scheme. To illustrate the results, we provide several numerical experiments both in one and two dimensions. These agree with the crack initiation criterion, which states that a fracture appears only when the stress overcomes a certain threshold, depending on the material.

M. Storath, L. Demaret and P. Massopust. Signal analysis based on complex wavelet signs, Appl. Comput. Harmon. Anal., 42(2):199  223, 2017.
[Abstract] [BibTeX]

Abstract We propose a signal analysis tool based on the sign (or the phase) of complex wavelet coefficients, which we call a signature. The signature is defined as the finescale limit of the signs of a signal's complex wavelet coefficients. We show that the signature equals zero at sufficiently regular points of a signal whereas at salient features, such as jumps or cusps, it is nonzero. At such feature points, the orientation of the signature in the complex plane can be interpreted as an indicator of local symmetry and antisymmetry. We establish that the signature rotates in the complex plane under fractional Hilbert transforms. We show that certain random signals, such as white Gaussian noise and Brownian motions, have a vanishing signature. We derive an appropriate discretization and show the applicability to signal analysis.

Abstract In this work we analyze the problem of phase retrieval from Fourier measurements with random diffraction patterns. To this end, we consider the recently introduced PhaseLift algorithm, which expresses the problem in the language of convex optimization. We provide recovery guarantees which require O ( log^2 d ) different diffraction patterns, thus improving on recent results by Candès et al. [1], which demand O ( log ^4 d ) different patterns.

[Abstract] [BibTeX] [.pdf]

Abstract In this paper we address the numerical solution of minimal norm residuals of nonlinear equations in finite dimensions. We take particularly inspiration from the problem of finding a sparse vector solution of phase retrieval problems by using greedy algorithms based on iterative residual minimizations in the pnorm, for 1≤ p≤ 2%. Due to the mild smoothness of the problem, especially for p → 1$, we develop and analyze a generalized version of iteratively reweighted least squares (IRLS). This simple and efficient algorithm performs the solution of optimization problems involving nonquadratic possibly nonconvex and nonsmooth cost functions, which can be transformed into a sequence of common least squares problems. The latter can be tackled eventually by more efficient numerical optimization methods. While its analysis has been by now developed in many different contexts (e.g., for sparse vector, lowrank matrix optimization, and for the solution of PDE involving pLaplacians) when the model equation is linear, no results are up to now provided in case of nonlinear ones. We address here precisely the convergence and the rate of error decay of IRLS for such nonlinear problems. The analysis of the convergence of the algorithm is based on its reformulation as an alternating minimization of an energy functional. In fact its main variables are the competitors to solutions of the intermediate reweighted least squares problems and their weights. Under a specific condition of coercivity often verified in practice and assumptions of local convexity, we are able to show convergence of IRLS to minimizers of the nonlinear residual problem. For the case where we are lacking the local convexity, we propose an appropriate convexification by quadratic perturbations. Eventually we are able to show convergence of this modified procedure to at least a very good approximation of stationary points of the original problem. In order to illustrate the theoretical results we conclude the paper with several numerical experiments. We first compare IRLS with standard Matlab optimization functions for a simple and easily presentable example. Furthermore we numerically validate our theoretical results in the more complicated framework of phase retrieval problems, which are our main motivation. Finally we examine the recovery capability of the algorithm in the context of data corrupted by impulsive noise where the sparsification of the residual is desired.

[Abstract] [BibTeX] [arXiv] [.pdf]

Abstract Iteratively reweighted least squares (IRLS) is a method for solving minimization problems involving nonquadratic cost functions, perhaps nonconvex and nonsmooth, which however can be described as the infimum over a family of quadratic functions. This transformation suggests an algorithmic scheme that solves a sequence of quadratic problems to be tackled efficiently by tools of numerical linear algebra. Its general scope and its usually simple implementation, transforming the initial nonconvex and nonsmooth minimization problem into a more familiar and easily solvable quadratic optimization problem, make it a versatile algorithm. However, despite its simplicity, versatility, and elegant analysis, the complexity of IRLS strongly depends on the way the solution of the successive quadratic optimizations is addressed. For the important special case of compressed sensing and sparse recovery problems in signal processing, we investigate theoretically and numerically how accurately one needs to solve the quadratic problems by means of the conjugate gradient (CG) method in each iteration in order to guarantee convergence. The use of the CG method may significantly speedup the numerical solution of the quadratic subproblems, in particular, when fast matrixvector multiplication (exploiting for instance the FFT) is available for the matrix involved. In addition, we study convergence rates. Our modified IRLS method outperforms state of the art first order methods such as Iterative Hard Thresholding (IHT) or Fast Iterative SoftThresholding Algorithm (FISTA) in many situations, especially in large dimensions. Moreover, IRLS is often able to recover sparse vectors from fewer measurements than required for IHT and FISTA.

[Abstract] [BibTeX] [.pdf]

Abstract This paper is concerned with the study of the consistency of a variational method for probability measure quantization, deterministically realized by means of a minimizing principle, balancing power repulsion and attraction potentials. The proof of consistency is based on the construction of a target energy functional whose unique minimizer is actually the given probability measure ω to be quantized. Then we show that the discrete functionals, defining the discrete quantizers as their minimizers, actually Γconverge to the target energy with respect to the narrow topology on the space of probability measures. A key ingredient is the reformulation of the target functional by means of a Fourier representation, which extends the characterization of conditionally positive semidefinite functions from points in generic position to probability measures. As a byproduct of the Fourier representation, we also obtain compactness of sublevels of the target energy in terms of uniform moment bounds, which already found applications in the asymptotic analysis of corresponding gradient flows. To model situations where the given probability is affected by noise, we further consider a modified energy, with the addition of a regularizing total variation term and we investigate again its point mass approximations in terms of Γconvergence. We show that such a discrete measure representation of the total variation can be interpreted as an additional nonlinear potential, repulsive at a short range, attractive at a medium range, and at a long range not having effect, promoting a uniform distribution of the point masses.

[Abstract] [BibTeX]

Abstract Networks or graphs play an important role in the biological sciences. Protein interaction networks and metabolic networks support the understanding of basic cellular mechanisms. In the human brain, networks of functional or structural connectivity model the informationflow between cortex regions. In this context, measures of network properties are needed. We propose a new measure, Ndim, estimating the complexity of arbitrary networks. This measure is based on a fractal dimension, which is similar to recently introduced boxcovering dimensions. However, boxcovering dimensions are only applicable to fractal networks. The construction of these networkdimensions relies on concepts proposed to measure fractality or complexity of irregular sets in ℝ n $backslashmathbb R\^n\$ .

[Abstract] [BibTeX] [.pdf]

Abstract We discuss the realization of a fast, robust and accurate pattern matching algorithm for comparison of digital images implemented by discrete Circular Harmonic expansions based on sampling theory. The algorithm and its performance for reassembling fragmented digital images are described in detail and illustrated by examples and data from the experimentation on an art fresco real problem. Because of the huge database of patterns and the largescale dimension, the results of the experimentation are relevant to describe the power of discrimination and the efficiency of such method.

[Abstract] [BibTeX] [doi]

Abstract Compressed sensing allows performing much fewer measurements than advised by the Shannon sampling theory. This is surprising because it requires the solution of a system of equations with much fewer equations than unknowns. This is possible if one can assume sparsity of the solution, which means that only a few components of the solution are significantly different from zero. An important ingredient for compressed sensing is the restricted isometry property (RIP) of the sensing matrix, which is satisfied for certain types of random measurement ensembles. Then a sparse solution can be found by minimizing the ℓ1norm. Using standard approaches, photoacoustic imaging generally neither satisfies sparsity of the data nor the RIP. Therefore, no theoretical recovery guarantees could be given. Despite ℓ1 minimization has been used for photoacoustic image reconstruction, only marginal improvements in comparison to classical photoacoustic reconstruction have been observed. We propose the application of a sparsifying temporal transformation to the detected pressure signals, which allows obtaining theoretical recovery guarantees for our compressed sensing scheme. Such a sparsifying transform can be found because spatial and temporal evolution of the pressure wave are not independent, but connected by the wave equation. We give an example of a sparsifying transform and apply our compressed sensing scheme to reconstruct images from simulated data.

[Abstract] [BibTeX] [doi]

Abstract Given an mtimesN matrix Phi, with m<N, the system of equations Phix=y is typically underdetermined and has infinitely many solutions. Various forms of optimization can extract a "best" solution. One of the oldest is to select the one with minimal lscr2 norm. It has been shown that in many applications a better choice is the minimal lscr1 norm solution. This is the case in compressive sensing, when sparse solutions are sought. The minimal lscr1 norm solution can be found by using linear programming; an alternative method is iterative reweighted least squares (IRLS), which in some cases is numerically faster. The main step of IRLS finds, for a given weight w, the solution with smallest lscr2(w) norm; this weight is updated at every iteration step: if x(n) is the solution at step n, then w(n) is defined by wi (n):=1/xi (n), i=1,...,N. We give a specific recipe for updating weights that avoids technical shortcomings in other approaches, and for which we can prove convergence under certain conditions on the matrix Phi known as the restricted isometry property. We also show that if there is a sparse solution, then the limit of the proposed algorithm is that sparse solution. It is also shown that whenever the solution at a given iteration is sufficiently close to the limit, then the remaining steps of the algorithm converge exponentially fast. In the standard version of the algorithm, designed to emulate lscr1minimization, the exponential rate is linear; in adapted versions aimed at lscrtauminimization with tau<1, we prove faster than linear rate.
