  text: We present a new proximal bundle method for Maximum-A-Posteriori (MAP) inference
    in structured energy minimization problems. The method optimizes a Lagrangean
    relaxation of the original energy minimization problem using a multi plane block-coordinate
    Frank-Wolfe method that takes advantage of the specific structure of the Lagrangean
    decomposition. We show empirically that our method outperforms state-of-the-art
    Lagrangean decomposition based algorithms on some challenging Markov Random Field,
    multi-label discrete tomography and graph matching problems.

  text: We consider the NP-hard problem of MAP-inference for undirected discrete graphical
    models. We propose a polynomial time and practically efficient algorithm for finding
    a part of its optimal solution. Specifically, our algorithm marks some labels
    of the considered graphical model either as (i) optimal, meaning that they belong
    to all optimal solutions of the inference problem; (ii) non-optimal if they provably
    do not belong to any solution. With access to an exact solver of a linear programming
    relaxation to the MAP-inference problem, our algorithm marks the maximal possible
    (in a specified sense) number of labels. We also present a version of the algorithm,
    which has access to a suboptimal dual solver only and still can ensure the (non-)optimality
    for the marked labels, although the overall number of the marked labels may decrease.
    We propose an efficient implementation, which runs in time comparable to a single
    run of a suboptimal dual solver. Our method is well-scalable and shows state-of-the-art
    results on computational benchmarks from machine learning and computer vision.

  text: 'We consider the MAP-inference problem for graphical models,which is a valued
    constraint satisfaction problem defined onreal numbers with a natural summation
    operation. We proposea family of relaxations (different from the famous Sherali-Adams
    hierarchy), which naturally define lower bounds for itsoptimum. This family always
    contains a tight relaxation andwe give an algorithm able to find it and therefore,
    solve theinitial non-relaxed NP-hard problem.The relaxations we consider decompose
    the original probleminto two non-overlapping parts: an easy LP-tight part and
    adifficult one. For the latter part a combinatorial solver must beused. As we
    show in our experiments, in a number of applica-tions the second, difficult part
    constitutes only a small fractionof the whole problem. This property allows to
    significantlyreduce the computational time of the combinatorial solver andtherefore
    solve problems which were out of reach before.'

  text: 'We introduce two novel methods for learning parameters of graphical models
    for image labelling. The following two tasks underline both methods: (i) perturb
    model parameters based on given features and ground truth labelings, so as to
    exactly reproduce these labelings as optima of the local polytope relaxation of
    the labelling problem; (ii) train a predictor for the perturbed model parameters
    so that improved model parameters can be applied to the labelling of novel data.
    Our first method implements task (i) by inverse linear programming and task (ii)
    using a regressor e.g. a Gaussian process. Our second approach simultaneously
    solves tasks (i) and (ii) in a joint manner, while being restricted to linearly
    parameterised predictors. Experiments demonstrate the merits of both approaches.'

  text: We present a novel convex relaxation and a corresponding inference algorithm
    for the non-binary discrete tomography problem, that is, reconstructing discrete-valued
    images from few linear measurements. In contrast to state of the art approaches
    that split the problem into a continuous reconstruction problem for the linear
    measurement constraints and a discrete labeling problem to enforce discrete-valued
    reconstructions, we propose a joint formulation that addresses both problems simultaneously,
    resulting in a tighter convex relaxation. For this purpose a constrained graphical
    model is set up and evaluated using a novel relaxation optimized by dual decomposition.
    We evaluate our approach experimentally and show superior solutions both mathematically
    (tighter relaxation) and experimentally in comparison to previously proposed relaxations.

  text: We propose a dual decomposition and linear program relaxation of the NP-hard
    minimum cost multicut problem. Unlike other polyhedral relaxations of the multicut
    polytope, it is amenable to efficient optimization by message passing. Like other
    polyhedral relaxations, it can be tightened efficiently by cutting planes.  We
    define an algorithm that alternates between message passing and efficient separation
    of cycle- and odd-wheel inequalities. This algorithm is more efficient than state-of-the-art
    algorithms based on linear programming, including algorithms written in the framework
    of leading commercial software, as we show in experiments with large instances
    of the problem from applications in computer vision, biomedical image analysis
    and data mining.

  text: We study the quadratic assignment problem, in computer vision also known as
    graph matching. Two leading solvers for this problem optimize the Lagrange decomposition
    duals with sub-gradient and dual ascent (also known as message passing) updates.
    We explore this direction further and propose several additional Lagrangean relaxations
    of the graph matching problem along with corresponding algorithms, which are all
    based on a common dual ascent framework. Our extensive empirical evaluation gives
    several theoretical insights and suggests a new state-of-the-art anytime solver
    for the considered problem. Our improvement over state-of-the-art is particularly
    visible on a new dataset with large-scale sparse problem instances containing
    more than 500 graph nodes each.

  text: We  propose  a  general  dual  ascent  framework  for  Lagrangean decomposition
    of combinatorial problems.  Although methods of this type have shown their efficiency
    for a number of problems, so far there was no general algorithm applicable to
    multiple problem types. In this work, we propose such a general algorithm. It
    depends on several parameters, which can be used to optimize its performance in
    each particular setting. We demonstrate efficacy of our method on graph matching
    and multicut problems, where it outperforms state-of-the-art solvers including
    those based on subgradient optimization and off-the-shelf linear programming solvers.
