Transferable Reward Learning by Dynamics-Agnostic Discriminator Ensemble

no code implementations1 Jun 2022 Fan-Ming Luo, Xingchen Cao, Rong-Jun Qin, Yang Yu

In this work, we present a dynamics-agnostic discriminator-ensemble reward learning method (DARL) within the AIL framework, capable of learning both state-action and state-only reward functions.

Improving Fictitious Play Reinforcement Learning with Expanding Models

no code implementations27 Nov 2019 Rong-Jun Qin, Jing-Cheng Pang, Yang Yu

However, learning to beat a pool in stochastic games, i. e., a wide distribution over policy models, is either sample-consuming or insufficient to exploit all models with limited amount of samples.

Multi-View Large-Scale Bundle Adjustment Method for High-Resolution Satellite Images

no code implementations22 May 2019 Xu Huang, Rong-Jun Qin

Given enough multi-view image corresponding points (also called tie points) and ground control points (GCP), bundle adjustment for high-resolution satellite images is used to refine the orientations or most often used geometric parameters Rational Polynomial Coefficients (RPC) of each satellite image in a unified geodetic framework, which is very critical in many photogrammetry and computer vision applications.

Using Orthophoto for Building Boundary Sharpening in the Digital Surface Model

no code implementations22 May 2019 Xiaohu Lu, Rong-Jun Qin, Xu Huang

Nowadays dense stereo matching has become one of the dominant tools in 3D reconstruction of urban regions for its low cost and high flexibility in generating dense 3D points.
