Risk-aware Flexible Resource Utilization in an Unbalanced Three-Phase Distribution Network using SDP-based Distributionally Robust Optimal Power Flow

no code implementations30 Aug 2023 Zelong Lu, Jianxue Wang, Mohammad Shahidehpour, Linquan Bai, Zuyi Li, Lei Yan, Xianlong Chen

This paper focuses on how a distribution system operator (DSO), taking over the distribution grid and market operations, would develop a risk-aware flexibility market to mitigate uncertainties in an unbalanced three-phase power distribution network.

Dynamic Feature-based Deep Reinforcement Learning for Flow Control of Circular Cylinder with Sparse Surface Pressure Sensing

no code implementations5 Jul 2023 Qiulei Wang, Lei Yan, Gang Hu, Wenli Chen, Bernd R. Noack

The resulting dynamic feature-based DRL (DF-DRL) automatically learns a feedback control in the plant without a dynamic model.

ROS-PyBullet Interface: A Framework for Reliable Contact Simulation and Human-Robot Interaction

no code implementations13 Oct 2022 Christopher E. Mower, Theodoros Stouraitis, João Moura, Christian Rauch, Lei Yan, Nazanin Zamani Behabadi, Michael Gienger, Tom Vercauteren, Christos Bergeles, Sethu Vijayakumar

However, there is a lack of software connecting reliable contact simulation with the larger robotics ecosystem (i. e. ROS, Orocos), for a more seamless application of novel approaches, found in the literature, to existing robotic hardware.

Reinforcement Learning for Cognitive Delay/Disruption Tolerant Network Node Management in an LEO-based Satellite Constellation

no code implementations27 Sep 2022 Xue Sun, Changhao Li, Lei Yan, Suzhi Cao

Therefore, this paper proposes a centralized approach to automatically manage cognitive DTN nodes in low earth orbit (LEO) satellite constellation scenarios based on the advanced reinforcement learning (RL) strategy advantage actor-critic (A2C).

Predict stock prices with ARIMA and LSTM

no code implementations31 Aug 2022 Ruochen Xiao, Yingying Feng, Lei Yan, Yihan Ma

For LSTM model, the data from 01 January 2010 to 31 December 2015 are selected as the training set, the data from 01 January 2016 to 31 December 2017 as the validation set and the data from 01 January 2018 to 31 December 2018 as the test set.

QoE-Aware Resource Allocation for Semantic Communication Networks

no code implementations28 May 2022 Lei Yan, Zhijin Qin, Rui Zhang, Yongzhao Li, Geoffrey Ye Li

Specifically, an approximate measure of semantic entropy is first developed to quantify the semantic information for different tasks, based on which a novel quality-of-experience (QoE) model is proposed.

Resource allocation for text semantic communications

1 code implementation16 Jan 2022 Lei Yan, Zhijin Qin, Rui Zhang, Yongzhao Li, Geoffrey Ye Li

Semantic communications have shown its great potential to improve the transmission reliability, especially in the low signal-to-noise regime.

Event-driven Two-stage Solution to Non-intrusive Load Monitoring

no code implementations27 Jul 2021 Lei Yan, Wei Tian, Jiayu Han, Zuyi Li

Existing methods of non-intrusive load monitoring (NILM) in literatures generally suffer from high computational complexity and/or low accuracy in identifying working household appliances.
