Notes:
- This is currently a development branch of ACE (though we are still tagging versions regularly). For the latest stable version see ACE1.jl and for a more user-oriented interface ACE1pack.jl
- Preliminary Documentation, WIP.
This package implements approximation schemes for permutation and isometry invariant functions, with focus on modelling atomic interactions. It provides constructions of symmetric polynomial bases, such as permutation and isometry invariance. Heavy use is made of trigonometric polynomials and spherical harmonics to obtain rotation invariance. Implementations of other symmetries are in preparation.
- Main new development towards nonlinear models and AD is on
mainbranch - AD is still a WIP, but expect this to be ready soon
- All previous branches are now in maintenance mode.
