Real-Time Progressive Learning: Accumulate Knowledge from Control with Neural-Network-Based Selective Memory

no code implementations8 Aug 2023 Yiming Fei, Jiangang Li, Yanan Li

Memory, as the basis of learning, determines the storage, update and forgetting of knowledge and further determines the efficiency of learning.

Selective Memory Recursive Least Squares: Recast Forgetting into Memory in RBF Neural Network Based Real-Time Learning

no code implementations15 Nov 2022 Yiming Fei, Jiangang Li, Yanan Li

In radial basis function neural network (RBFNN) based real-time learning tasks, forgetting mechanisms are widely used such that the neural network can keep its sensitivity to new data.

A machine-learning-based tool for last closed-flux surface reconstruction on tokamaks

no code implementations12 Jul 2022 Chenguang Wan, Zhi Yu, Alessandro Pau, Xiaojuan Liu, Jiangang Li

Tokamaks allow to confine fusion plasma with magnetic fields and one of the main challenges in the control of the magnetic configuration is the prediction/reconstruction of the Last Closed-Flux Surface (LCFS).

Experiment data-driven modeling of tokamak discharge in EAST

no code implementations21 Jul 2020 Chenguang Wan, Jiangang Li, Zhi Yu, Xiaojuan Liu

By using the data-driven methodology, we exploit the temporal sequence of control signals for a large set of EAST discharges to develop a deep learning model for modeling discharge diagnostic signals, such as electron density $n_{e}$, store energy $W_{mhd}$ and loop voltage $V_{loop}$.
