GLIME: General, Stable and Local LIME Explanation

1 code implementation NeurIPS 2023 Zeren Tan, Yang Tian, Jian Li

Additionally, LIME's sampling neighborhood is non-local and biased towards the reference, resulting in poor local fidelity and sensitivity to reference choice.

Theoretical foundations of studying criticality in the brain

no code implementations9 Jun 2023 Yang Tian, Zeren Tan, Hedong Hou, Guoqi Li, Aohua Cheng, Yike Qiu, Kangyu Weng, Chun Chen, Pei Sun

These problems stem from the non-triviality and immaturity of the physical theories that analytically derive brain criticality and the statistic techniques that estimate brain criticality from empirical data.

Koopman neural operator as a mesh-free solver of non-linear partial differential equations

1 code implementation24 Jan 2023 Wei Xiong, Xiaomeng Huang, Ziyang Zhang, Ruixuan Deng, Pei Sun, Yang Tian

By approximating the Koopman operator, an infinite-dimensional operator governing all possible observations of the dynamic system, to act on the flow mapping of the dynamic system, we can equivalently learn the solution of a non-linear PDE family by solving simple linear prediction problems.
