STANKER: Stacking Network based on Level-grained Attention-masked BERT for Rumor Detection on Social Media

1 code implementation EMNLP 2021 Dongning Rao, Xin Miao, Zhihua Jiang, Ran Li

Rumor detection on social media puts pre-trained language models (LMs), such as BERT, and auxiliary features, such as comments, into use.

Decision-Oriented Learning for Future Power System Decision-Making under Uncertainty

no code implementations8 Jan 2024 Ran Li, Haipeng Zhang, Mingyang Sun, Fei Teng, Can Wan, Salvador Pineda, Georges Kariniotakis

This paper first elaborates on the mismatch between more accurate forecasts and more optimal decisions in the power system caused by statistical-based learning (SBL) and explains how DOL resolves this problem.

Coordinated Planning of Offshore Charging Stations and Electrified Ships: A Case Study on Shanghai-Busan Maritime Route

no code implementations25 Dec 2023 Hao Li, Hanqi Tao, Wentao Huang, Hongcai Zhang, Ran Li

Despite the success of electric vehicles on land, electrification of maritime ships is challenged by the dilemma of range anxiety and cargo-carrying capacity.

Adaptive Decision-Objective Loss for Forecast-then-Optimize in Power Systems

no code implementations21 Dec 2023 Haipeng Zhang, Ran Li, Mingyang Sun, Teng Fei

However, the implementation of decision loss in power systems faces challenges in 1) accommodating multi-stage decision-making problems where upstream optimality cannot guarantee final optimality; 2) adapting to dynamic environments such as changing parameters and nature of the problem like continuous or discrete optimization tasks.

Probabilistic Forecast-based Portfolio Optimization of Electricity Demand at Low Aggregation Levels

no code implementations18 Apr 2023 Jungyeon Park, Estêvão Alvarenga, Jooyoung Jeon, Ran Li, Fotios Petropoulos, Hokyun Kim, Kwangwon Ahn

Using probabilistic load forecasts produced by either ARMA-GARCH models or kernel density estimation (KDE), we propose three approaches to creating a portfolio of residential households' demand: Forecast Validated, Seasonal Residual, and Seasonal Similarity.

A Joint Model and Data Driven Method for Distributed Estimation

no code implementations30 Mar 2023 Meng He, Ran Li, Chuan Huang, Shulong Zhang

To this end, we propose a joint model and data driven distributed estimation method by designing the optimal quantizers and fusion center (FC) based on the Bayesian and minimum mean square error (MMSE) criterions.

Synthetic Power Analyses: Empirical Evaluation and Application to Cognitive Neuroimaging

no code implementations11 Oct 2022 Peiye Zhuang, Bliss Chapman, Ran Li, Oluwasanmi Koyejo

We propose synthetic power analyses; a framework for estimating statistical power at various sample sizes, and empirically explore the performance of synthetic power analysis for sample size selection in cognitive neuroscience experiments.

Towards Comprehensive Monocular Depth Estimation: Multiple Heads Are Better Than One

no code implementations16 Nov 2021 Shuwei Shao, Ran Li, Zhongcai Pei, Zhong Liu, Weihai Chen, Wentao Zhu, Xingming Wu, Baochang Zhang

In this work, we investigate into the phenomenon and propose to integrate the strengths of multiple weak depth predictor to build a comprehensive and accurate depth predictor, which is critical for many real-world applications, e. g., 3D reconstruction.

Probing black hole microstructure with the kinetic turnover of phase transition

no code implementations18 Feb 2021 Ran Li, Kun Zhang, Jin Wang

By treating black hole as the macroscopic stable state on the free energy landscape, we propose that the stochastic dynamics of the black hole phase transition can be effectively described by the Langevin equation or equivalently by the Fokker-Planck equation in phase space.

Hawking radiation, local temperatures, and nonequilibrium thermodynamics of the black holes with non-killing horizon

no code implementations29 Jan 2021 Ran Li, Jin Wang

Therefore, the black hole with non-killing horizon can be overall in non-equilibrium steady state while the Hawking temperature of the black funnel can be viewed as the local temperature and the corresponding Hawking radiation can be regarded as being in the local equilibrium with the horizon of the black funnel.
