Efficient Scene Compression for Visual-based Localization
MarcelaMera-Trujillo, BenjaminSmith, VictorFragoso....
Published date-11/27/2020
3DReconstruction
Estimating the pose of a camera with respect to a 3D reconstruction or scene representation is a crucial step for many mixed reality and robotics applications. Given the vast amount …
Simulation-efficient marginal posterior estimation with swyft: stop wasting your precious time
BenjaminKurtMiller, AlexCole, GillesLouppe....
Published date-11/27/2020
BayesianInference
We present algorithms (a) for nested neural likelihood-to-evidence ratio estimation, and (b) for simulation reuse via an inhomogeneous Poisson point process cache of parameters and corresponding simulations. Together, these algorithms …
Generalized Pose-and-Scale Estimation using 4-Point Congruence Constraints
VictorFragoso, SudiptaSinha....
Published date-11/27/2020
We present gP4Pc, a new method for computing the absolute pose of a generalized camera with unknown internal scale from four corresponding 3D point-and-ray pairs. Unlike most pose-and-scale methods, gP4Pc …
Efficient Information Diffusion in Time-Varying Graphs through Deep Reinforcement Learning
MatheusR.F.Mendonça, AndréM.S.Barreto, ArturZiviani....

GraphEmbedding
Network seeding for efficient information diffusion over time-varying graphs~(TVGs) is a challenging task with many real-world applications. There are several ways to model this spatio-temporal influence maximization problem, but the …
Generalization in Reinforcement Learning by Soft Data Augmentation
NicklasHansen, XiaolongWang....
Published date-11/26/2020
DataAugmentation
Extensive efforts have been made to improve the generalization ability of Reinforcement Learning (RL) methods via domain randomization and data augmentation. However, as more factors of variation are introduced during …
