Constructing Data Transaction Chains Based on Opportunity Cost Exploration

no code implementations8 Apr 2024 Jie Liu, Tao Feng, Yan Jiang, Peizheng Wang, Chao Wu

However, the inherent replicability and privacy concerns of data make it challenging to directly apply traditional trading theories to data markets.

Oscillations-Aware Frequency Security Assessment via Efficient Worst-Case Frequency Nadir Computation

no code implementations26 Feb 2024 Yan Jiang, Hancheng Min, Baosen Zhang

Frequency security assessment following major disturbances has long been one of the central tasks in power system operations.

Balanced and Explainable Social Media Analysis for Public Health with Large Language Models

1 code implementation12 Sep 2023 Yan Jiang, Ruihong Qiu, Yi Zhang, Peng-Fei Zhang

Furthermore, an LLMs explanation mechanism is proposed by prompting an LLM with the predicted results from BERT models.

Equilibria of Fully Decentralized Learning in Networked Systems

no code implementations15 May 2023 Yan Jiang, Wenqi Cui, Baosen Zhang, Jorge Cortés

Existing settings of decentralized learning either require players to have full information or the system to have certain special structure that may be hard to check and hinder their applicability to practical systems.

Zero-Shot Video Editing Using Off-The-Shelf Image Diffusion Models

Weak Collocation Regression method: fast reveal hidden stochastic dynamics from high-dimensional aggregate data

no code implementations6 Sep 2022 Liwei Lu, Zhijun Zeng, Yan Jiang, Yi Zhu, Pipi Hu

Taking the collocations of Gaussian functions as the test functions in the weak form of the FP equation, we transfer the derivatives to the Gaussian functions and thus approximate the weak form by the expectational sum of the data.


On the Performance of Data Compression in Clustered Fog Radio Access Networks

no code implementations1 Jul 2022 Haonan Hu, Yan Jiang, Jiliang Zhang, Yanan Zheng, Qianbin Chen, Jie Zhang

The fog-radio-access-network (F-RAN) has been proposed to address the strict latency requirements, which offloads computation tasks generated in user equipments (UEs) to the edge to reduce the processing latency.

Few-Shot Stance Detection via Target-Aware Prompt Distillation

no code implementations27 Jun 2022 Yan Jiang, Jinhua Gao, HuaWei Shen, Xueqi Cheng

The main challenge of this task comes two-fold: few-shot learning resulting from the varying targets and the lack of contextual information of the targets.

Structured Neural-PI Control for Networked Systems: Stability and Steady-State Optimality Guarantees

1 code implementation1 Jun 2022 Wenqi Cui, Yan Jiang, Baosen Zhang, Yuanyuan Shi

We explicitly characterize the stability conditions and engineer neural networks that satisfy them by design.

Stable Reinforcement Learning for Optimal Frequency Control: A Distributed Averaging-Based Integral Approach

no code implementations1 May 2022 Yan Jiang, Wenqi Cui, Baosen Zhang, Jorge Cortés

Specifically, we use RL to learn a neural network-based control policy mapping from the integral variables of DAI to the controllable power injections which provides optimal transient frequency control, while DAI inherently ensures the frequency restoration and optimal economic dispatch.

Modified Gaussian Process Regression Models for Cyclic Capacity Prediction of Lithium-ion Batteries

no code implementations31 Dec 2020 Kailong Liu, Xiaosong Hu, Zhongbao Wei, Yi Li, Yan Jiang

Experimental results demonstrate that the modified Gaussian process regression model considering the battery electrochemical and empirical ageing signature outperforms other counterparts and is able to achieve satisfactory results for both one-step and multi-step predictions.


Reinforcement Learning for Optimal Primary Frequency Control: A Lyapunov Approach

1 code implementation11 Sep 2020 Wenqi Cui, Yan Jiang, Baosen Zhang

As more inverter-connected renewable resources are integrated into the grid, frequency stability may degrade because of the reduction in mechanical inertia and damping.
