Image Reconstruction from Electroencephalography Using Latent Diffusion

1 code implementation1 Apr 2024 Teng Fei, Virginia de Sa

In this work, we have adopted the diffusion-based image reconstruction pipeline previously used for fMRI image reconstruction and applied it to Electroencephalography (EEG).

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.

STICC: A multivariate spatial clustering method for repeated geographic pattern discovery with consideration of spatial contiguity

1 code implementation17 Mar 2022 Yuhao Kang, Kunlin Wu, Song Gao, Ignavier Ng, Jinmeng Rao, Shan Ye, Fan Zhang, Teng Fei

In this paper, we propose a Spatial Toeplitz Inverse Covariance-Based Clustering (STICC) method that considers both attributes and spatial relationships of geographic objects for multivariate spatial clustering.

Extracting human emotions at different places based on facial expressions and spatial clustering analysis

no code implementations6 May 2019 Yuhao Kang, Qingyuan Jia, Song Gao, Xiaohuan Zeng, Yueyao Wang, Stephan Angsuesser, Yu Liu, Xinyue Ye, Teng Fei

In this study, a novel framework for extracting human emotions from large-scale georeferenced photos at different places is proposed.

On Lower Central Series Quotients of Finitely Generated Algebras over $\mathbb{Z}$

no code implementations5 Sep 2013 Katherine Cordwell, Teng Fei, Kathleen Zhou

Let $A$ be an associative unital algebra, $B_k$ its successive quotients of lower central series and $N_k$ the successive quotients of ideals generated by lower central series.
