RC-SLAM: Road Constrained Stereo Visual SLAM System Based on Graph Optimization [PDF]
SensorsIntelligent vehicles are constrained by road, resulting in a disparity between the assumed six degrees of freedom (DoF) motion within the Visual Simultaneous Localization and Mapping (SLAM) system and the approximate planar motion of vehicles in local ...

Learning Multimodal Graph-to-Graph Translation for Molecular Optimization
CoRR, 2019 We view molecular optimization as a graph-to-graph translation problem. The goal is to learn to map from one molecular graph to another with better properties based on an available corpus of paired molecules. Since molecules can be optimized in different

Graph Bisection with Pareto Optimization [PDF]
ACM Journal of Experimental Algorithmics, 2015 We introduce FlowCutter, a novel algorithm to compute a set of edge cuts or node separators that optimize cut size and balance in the Pareto sense. Our core algorithm heuristically solves the balanced connected st -edge-cut problem, where two given nodes s and t must ...

A path following algorithm for the graph matching problem [PDF]
, 2008 We propose a convex-concave programming approach for the labeled weighted graph matching problem. The convex-concave programming formulation is obtained by rewriting the weighted graph matching problem as a least-square problem on the set of permutation ...
