class lgatr.primitives.config.LGATrConfig(use_fully_connected_subgroup=True, use_bivector=True, use_geometric_product=True)[source]

Bases: object

Configuration for global settings like the symmetry group.

Parameters:

use_fully_connected_subgroup (bool) – If True, model is only equivariant with respect to the fully connected subgroup of the Lorentz group, the proper orthochronous Lorentz group \(SO^+(1,3)\), which does not include parity and time reversal. This setting affects how the EquiLinear maps work: For \(SO^+(1,3)\), they include transitions scalars/pseudoscalars vectors/axialvectors and among bivectors, effectively treating the pseudoscalar/axialvector representations like another scalar/vector. Defaults to False, because parity-odd representations are usually not important in high-energy physics simulations.
use_bivector (bool) – If False, the bivector components are set to zero after they are created in the GeometricBilinear layer. This is a toy switch to explore the effect of higher-order representations.
use_geometric_product (bool) – If False, the GeometricBilinear layer is replaced by a EquiLinear + ScalarGatedNonlinearity layer. This is a toy switch to explore the effect of the geometric product.
