A new communication paradigm: from bit accuracy to semantic fidelity

no code implementations29 Jan 2021 Guangming Shi, Dahua Gao, Xiaodan Song, Jingxuan Chai, Minxi Yang, Xuemei Xie, Leida Li, Xuyang Li

In this article, we deploy semantics to solve the spectrum and power bottleneck and propose a first understanding and then transmission framework with high semantic fidelity.

NeuralSI: Structural Parameter Identification in Nonlinear Dynamical Systems

1 code implementation26 Aug 2022 Xuyang Li, Hamed Bolandi, Talal Salem, Nizar Lajnef, Vishnu Naresh Boddeti

Structural monitoring for complex built environments often suffers from mismatch between design, laboratory testing, and actual built parameters.

Physics Informed Neural Network for Dynamic Stress Prediction

no code implementations28 Nov 2022 Hamed Bolandi, Gautam Sreekumar, Xuyang Li, Nizar Lajnef, Vishnu Naresh Boddeti

Therefore, to reduce computational cost while maintaining accuracy, a Physics Informed Neural Network (PINN), PINN-Stress model, is proposed to predict the entire sequence of stress distribution based on Finite Element simulations using a partial differential equation (PDE) solver.

Neuro-DynaStress: Predicting Dynamic Stress Distributions in Structural Components

no code implementations19 Dec 2022 Hamed Bolandi, Gautam Sreekumar, Xuyang Li, Nizar Lajnef, Vishnu Naresh Boddeti

Therefore, to reduce computational cost while preserving accuracy, a deep learning model, Neuro-DynaStress, is proposed to predict the entire sequence of stress distribution based on finite element simulations using a partial differential equation (PDE) solver.

Low-Carbon Economic Dispatch of Bulk Power Systems Using Nash Bargaining Game

no code implementations30 Jan 2023 Xuyang Li, Guangchun Ruan, Haiwang Zhong

Because the Nash bargaining solution satisfies Pareto effectiveness, we analyze the computational complexity of Pareto frontiers with parametric linear programming and interpret the inefficiency of the method.

Rethinking the editing of generative adversarial networks: a method to estimate editing vectors based on dimension reduction

no code implementations7 Mar 2023 Yuhan Cao, Haoran Jiang, Zhenghong Yu, Qi Li, Xuyang Li

While Generative Adversarial Networks (GANs) have recently found applications in image editing, most previous GAN-based image editing methods require largescale datasets with semantic segmentation annotations for training, only provide high level control, or merely interpolate between different images.
