Effort Discrimination and Curvature of Contest Technology in Conflict Networks

no code implementations20 Feb 2023 Xiang Sun, Jin Xu, Junjie Zhou

When the contest technology in each battle is of Tullock form, a surprising neutrality result holds within the class of semi-symmetric conflict network structures: both the aggregate actions and equilibrium payoffs under two regimes are the same.

SAT: Size-Aware Transformer for 3D Point Cloud Semantic Segmentation

no code implementations17 Jan 2023 Junjie Zhou, Yongping Xiong, Chinwai Chiu, Fangyu Liu, Xiangyang Gong

In this paper, we propose the Size-Aware Transformer (SAT) that can tailor effective receptive fields for objects of different sizes.

Welfare and Distributional Effects of Joint Intervention in Networks

no code implementations8 Jun 2022 Ryan Kor, Junjie Zhou

We show that the welfare effect of joint intervention is shaped by the principal eigenvalue, while the distributional effect is captured by the dispersion of the corresponding eigenvalues, i. e., the eigen-centralities.

Unsignalized Intersection Management Strategy for Mixed Autonomy Traffic Streams

no code implementations7 Apr 2022 Junjie Zhou, Zhaokun Shen, Xiaofan Wang, Lin Wang

Combined with the designed vehicle planning and control algorithm, the unsignalized intersection management strategy consists of two parts: the heuristic priority queues based right of way allocation (HPQ) algorithm, and the vehicle planning and control algorithm.

Research on the Inverse Kinematics Prediction of a Soft Biomimetic Actuator via BP Neural Network

no code implementations26 Oct 2021 Huichen Ma, Junjie Zhou, Jian Zhang, Lingyu Zhang

After training with sample data, the BP neural network model can represent the relation between the manipulator tip position and the pressure applied to the chambers.

Multi-activity Influence and Intervention

no code implementations17 Jun 2021 Ryan Kor, Junjie Zhou

Using a general network model with multiple activities, we analyse a planner's welfare maximising interventions taking into account within-activity network spillovers and cross-activity interdependence.

Structural Interventions in Networks

no code implementations29 Jan 2021 Yang Sun, Wei Zhao, Junjie Zhou

Two types of interventions are commonly implemented in networks: characteristic intervention, which influences individuals' intrinsic incentives, and structural intervention, which targets the social links among individuals.
