A General Description of Criticality in Neural Network Models

no code implementations25 Aug 2023 Longbin Zeng, Fengjian Feng, Wenlian Lu

Recent experimental observations have supported the hypothesis that the cerebral cortex operates in a dynamical regime near criticality, where the neuronal network exhibits a mixture of ordered and disordered patterns.

Digital Twin Brain: a simulation and assimilation platform for whole human brain

no code implementations2 Aug 2023 Wenlian Lu, Longbin Zeng, Xin Du, Wenyong Zhang, Shitong Xiang, Huarui Wang, Jiexiang Wang, Mingda Ji, Yubo Hou, Minglong Wang, Yuhao Liu, Zhongyu Chen, Qibao Zheng, Ningsheng Xu, Jianfeng Feng

In comparison to most brain simulations with a homogeneous global structure, we highlight that the sparseness, couplingness and heterogeneity in the sMRI, DTI and PET data of the brain has an essential impact on the efficiency of brain simulation, which is proved from the scaling experiments that the DTB of human brain simulation is communication-intensive and memory-access intensive computing systems rather than computation-intensive.

Rethinking Precision of Pseudo Label: Test-Time Adaptation via Complementary Learning

no code implementations15 Jan 2023 Jiayi Han, Longbin Zeng, Liang Du, Weiyang Ding, Jianfeng Feng

In this work, we propose a novel complementary learning approach to enhance test-time adaptation (TTA), which has been proven to exhibit good performance on testing data with distribution shifts such as corruptions.
