Optimal Region Search with Submodular Maximization [PDF]
Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence, 2020 Region search is an important problem in location-based services due to its wide applications. In this paper, we study the problem of optimal region search with submodular maximization (ORS-SM). This problem considers a region as a connected subgraph.

Learning with submodular functions: A convex optimization perspective [PDF]
, 2013 International audienceSubmodular functions are relevant to machine learning for at least two reasons: (1) some problems may be expressed directly as the optimization of submodular functions and (2) the lovasz extension of submodular functions provides a ...

CrossPatch-Based Rolling Label Expansion for Dense Stereo Matching
IEEE Access, 2020 We present a novel algorithm called crosspatch-based rolling label expansion for accurate stereo matching. This optimization-based approach can effectively estimate the 3D label of each pixel from huge and infinite label space and then generate a ...

Mobility-Aware Traffic Offloading via Cooperative Coded Edge Caching
IEEE Access, 2020 With caching popular contents at the small-cell base stations (SBSs), cooperative edge caching has emerged as an effective approach to offload explosively increasing network traffic from a massive number of users in mobile edge networks (MENs).
