ACE.jl Documentation
This package implements approximation schemes for symmetric functions (including invariant scalars, equi-variant vectors and tensors ...). The origin of this effort was in modelling atomic interactions, hence the most complete implementation focus on permutations and isometries, but much of the code is more general. Extensions to other symmetries are therefore planned for the near future.
Although the original focus was on modelling atomic interactions, the scope is in principle much broader hence the ACE.jl
core library is agnostic about the application domain. It provides constructions of symmetric polynomial bases. Application-specific layers are provided in the related packaged within ACEsuit.
The original implemention was based on the Atomic Cluster Expansion (ACE) described in the following references:
