Structured Deep Neural Networks-Based Backstepping Trajectory Tracking Control for Lagrangian Systems

no code implementations1 Mar 2024 Jiajun Qian, Liang Xu, Xiaoqiang Ren, Xiaofan Wang

In addition, improved control performance can be achieved by further optimizing neural network parameters.

Autoregressive GNN-ODE GRU Model for Network Dynamics

no code implementations19 Nov 2022 Bo Liang, Lin Wang, Xiaofan Wang

In this paper, we propose an Autoregressive GNN-ODE GRU Model (AGOG) to learn and capture the continuous network dynamics and realize predictions of node states at an arbitrary time in a data-driven manner.

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.

Controllability of Multilayer Networked Sampled-data Systems

no code implementations4 Mar 2022 Zixuan Yang, Xiaofan Wang, Lin Wang

This paper explores the state controllability of multilayer networked sampled-data systems with inter-layer couplings, where zero-order holders (ZOHs) are on the control and transmission channels.

Controllability of Networked Sampled-data Systems

no code implementations18 Feb 2022 Zixuan Yang, Xiaofan Wang, Lin Wang

The controllability of networked sampled-data systems with zero-order holders on the control and transmission channels is explored, where single- and multi-rate sampling patterns are considered, respectively.

Investigating and Modeling the Dynamics of Long Ties

1 code implementation22 Sep 2021 Ding Lyu, Yuan Yuan, Lin Wang, Xiaofan Wang, Alex Pentland

Long ties, the social ties that bridge different communities, are widely believed to play crucial roles in spreading novel information in social networks.

Leader-Driven Opinion Dynamics in Signed Social Networks With Asynchronous Trust/Distrust Level Evolution

no code implementations19 Jul 2020 Lei Shi, Yuhua Cheng, Jinliang Shao, Xiaofan Wang, Hanmin Sheng

Trust and distrust are common in the opinion interactions among agents in social networks, and they are described by the edges with positive and negative weights in the signed digraph, respectively.

Go viral or go broadcast? Characterizing the virality and growth of cascades

1 code implementation1 Jun 2020 Yafei Zhang, Lin Wang, Jonathan J. H. Zhu, Xiaofan Wang

Quantifying the virality of cascades is an important question across disciplines such as the transmission of disease, the spread of information and the diffusion of innovations.

Approximate Computational Approaches for Bayesian Sensor Placement in High Dimensions

no code implementations1 Mar 2017 Xiao Lin, Asif Chowdhury, Xiaofan Wang, Gabriel Terejanu

Then, sensors are placed where highest mutual information (lower bound) is achieved and QoI is inferred via Bayes rule given sensor measurements.

Feedback Control of Real-Time Display Advertising

1 code implementation3 Mar 2016 Wei-Nan Zhang, Yifei Rong, Jun Wang, Tianchi Zhu, Xiaofan Wang

In this paper, we propose a feedback control mechanism for RTB which helps advertisers dynamically adjust the bids to effectively control the KPIs, e. g., the auction winning ratio and the effective cost per click.
