The finetuning model does decline in performance within the equilibrium and weak-attraction regions compared to the pretraining MACE-MP models. This degradation can be attributed to the complexity in the interaction energy which is not determined solely by the combined system's total energy but by its energy relative to the isolated framework and gas molecule. The finetuning process can disrupt the delicate balance originally established with biases toward the data represented in the finetuning dataset.
