Optimizing Hard Thresholding for Sparse Model Discovery
Derek W. Jollie, Scott G. McCalla
Many model selection algorithms rely on sparse dictionary learning to provide interpretable and physics-based governing equations. The optimization algorithms typically use a hard…
A PDE Model for Janus Particle Swarming
Griffin Smith, Nathan Stouffer, Scott G. McCalla +1
It has been experimentally shown that Brownian motion and active forward drift controlled by quorum sensing is sufficient to produce clustering behavior in orientable Janus particl…
Fronts under arrest II: analytical foundations
James H. von Brecht, Scott G. McCalla, Eun Heui Kim
We study a class of minimal geometric partial differential equations that serves as a framework to understand the evolution of boundaries between states in different pattern formin…
Random Feature Models for Learning Interacting Dynamical Systems
Yuxuan Liu, Scott G. McCalla, Hayden Schaeffer
Particle dynamics and multi-agent systems provide accurate dynamical models for studying and forecasting the behavior of complex interacting systems. They often take the form of a…
Extending the step-size restriction for gradient descent to avoid strict saddle points
Hayden Schaeffer, Scott G. McCalla
We provide larger step-size restrictions for which gradient descent based algorithms (almost surely) avoid strict saddle points. In particular, consider a twice differentiable (non…
Statistical Model of Heavy-Ion Fusion-Fission Reactions
J. P. Lestone, S. G. McCalla
Cross-section and neutron-emission data from heavy-ion fusion-fission reactions are consistent with the fission of fully equilibrated systems with fission lifetime estimates obtain…
