A Fully Dual Domain Decomposition Method for Extreme Learning Machines Using GenEO Spectral Coarse Spaces
Chang-Ock Lee, Byungeun Ryoo
Extreme learning machines (ELMs) are a class of machine learning algorithms that randomly intialize and subsequently fix the hidden layer parameters, and solve for the last layer c…

Hybrid Least Squares/Gradient Descent Methods for MIONets
Jun Choi, Chang-Ock Lee, Minam Moon
In this paper, we propose an efficient hybrid least squares/gradient descent (LSGD) method for MIONets to accelerate training. This method generalizes the LSGD method for DeepONets…
