Supplementary Material: Efficient and Exact MAP-MRF Inference using Branch and Bound
نویسندگان
چکیده
By default, the edge-consistent LPR is solved using Message Passing (MP) algorithm to initialize β until convergence or for at most 1000 iterations, whichever comes first. If the gap between the upper and lower bounds is not smaller than 10 (stopping criteria) already, we further apply our BB method or MPLP-CP method [4]. Both methods stop when the same stopping criteria (gap < 10) is reached. For MPLP-CP method [4], by default, we alternate between adding 20 clusters at a time and running MPLP for 100 more iterations.

Efficient and Exact MAP-MRF Inference using Branch and Bound
We propose two novel Branch-and-Bound (BB) methods to efficiently solve exact MAPMRF inference on problems with a large number of states (per variable) H. By organizing the data in a suitable structure, the time complexity of our best method for evaluating the bound at each branch is reduced from O(H) to O(H). This permits searching for the MAP solution in O(BH +Q) instead of O(BH) (without usi...
متن کاملMaximum Contact Map Overlap Revisited
Among the measures for quantifying the similarity between three-dimensional (3D) protein structures, maximum contact map overlap (CMO) received sustained attention during the past decade. Despite this, the known algorithms exhibit modest performance and are not applicable for large-scale comparison. This article offers a clear advance in this respect. We present a new integer programming model ...
متن کاملEfficient Exact Inference for 3D Indoor Scene Understanding
In this paper we propose the first exact solution to the problem of estimating the 3D room layout from a single image. This problem is typically formulated as inference in a Markov random field, where potentials count image features (e.g ., geometric context, orientation maps, lines in accordance with vanishing points) in each face of the layout. We present a novel branch and bound approach whi...
متن کاملDiscrete Optimization for Interpretable Study Populations and Randomization Inference in an Observational Study of Severe Sepsis Mortality
Motivated by an observational study of the effect of hospital ward versus intensive care unit admission on severe sepsis mortality, we develop methods to address two common problems in observational studies: (1) when there is a lack of covariate overlap between the treated and control groups, how to define an interpretable study population wherein inference can be conducted without extrapolatin...
متن کاملActive tectonic evidences related to the Main Recent Fault in the Sarvabad region, NW Iran
-Introduction The Main Recent Fault (MRF) is a seismic structure on the northwestern boundary of the Zagros belt and southern border of the Sanandaj-Sirjan belt. This fault as a major strike-slip fault consists of several segments in the Zagros collision zone. The seismic activity of the southwestern segments is greater than the northwestern segments. Several earthquake events have occurred al...
