Less is more: a new machine-learning methodology for spatiotemporal systems
《Communications in Theoretical Physics》2022年第5期114-120,共7页Sihan Feng Kang Wang Fuming Wang Yong Zhang Hong Zhao 
support from the NSFC(Grants No.11975189,No.11975190).
Machine learning provides a way to use only portions of the variables of a spatiotemporal system to predict its subsequent evolution and consequently avoids the curse of dimensionality.The learning machines employed f...
