Noether Model Zoo

The Noether Framework includes base implementations for several state-of-the-art models:

Model	Paper	Implementation	Notes
AB-UPT	arXiv:2502.09692	ab_upt.py	-
Transformer	-	transformer.py	-
Transolver	arXiv:2402.02366	transolver.py	Transolver is a Transformer with a different attention config
Transolver++	arXiv:2502.02414	Schema only: transolver.py	Transolver++ is a Transolver with a different attention config
UPT	arXiv:2402.12365	upt.py	-

• Transformer & Transolver(++): These models are implemented as a backbone; consisting of a stack of layers. Transolver replaces the standard attention mechanism with Physics-Attention. For these two models, input embedding and output projection must be implemented by an extra wrapper module that uses the backbone.

• UPT & AB-UPT: In contrast, these models are “off-the-shelf” implementations, meaning they include the full architecture, including input embedding and output projection.
