The Structure Matching metric assesses whether the 20 sampled structures include the ground truth structure from the test set, which was used to generate the corresponding textual description. Given that the test set consists of future data and including more than 20 atoms, this metric is particularly challenging. Nonetheless, Crystal CLIP can generate 20 % of unseen ground truth structures within the text set even when the type of textual description is general text. Notably, it significantly outperforms baseline BERT, indicating its superior ability to replicate the precise structure as described by the text.
