Remarkable new paper by my postdoc Matt Golden, with a novel algorithm for model discovery in physics. Training that would have taken the age of the universe to complete with prior algorithms can now be achieved in a day. #machinelearning #physics arxiv.org/abs/2405.09579
Scalable Sparse Regression for Model Discovery: The Fast Lane to Insight

Scalable Sparse Regression for Model Discovery: The Fast Lane to Insight

There exist endless examples of dynamical systems with vast available data and unsatisfying mathematical descriptions. Sparse regression applied to symbolic libraries has quickly emerged as a...
