Reconstructing Multi-Scale Physical Fields from Extremely Sparse Measurements with an Autoencoder-Diffusion Cascade
Letian Yi, Tingpeng Zhang, Mingyuan Zhou +3
Extreme sensor sparsity makes full-field reconstruction a fundamentally ill-posed problem in scientific sensing,where the goal is to infer physical fields from sparse measurements.…
A unified framework for equation discovery and dynamic prediction of hysteretic systems
Siyuan Yang, Wei Liu, Zhilu Lai
Hysteresis is a nonlinear phenomenon with memory effects, where a system's output depends on both its current state and past states. It is prevalent in various physical and mechani…
