Why is ScaffoldSplitter recommended for molecular data?

ScaffoldSplitter is essential in drug discovery to prevent data leakage. It ensures that molecules with similar core structures are grouped together, providing a more accurate assessment of how the model generalizes to entirely new chemical spaces.

Can I use DeepChem for materials science tasks?

Absolutely. DeepChem includes specialized models like CGCNN and MEGNet for predicting crystal properties such as bandgap and formation energy.

Does this skill support Graph Neural Networks (GNNs)?

Yes, DeepChem provides built-in support for various GNN architectures including GCN, GAT, MPNN, and AttentiveFP, along with the necessary graph featurizers.

Does it support transfer learning?

Yes, you can leverage pretrained models like ChemBERTa, GROVER, and MolFormer, which are highly effective for improving model performance on small datasets.

What chemical data formats can I use with this skill?

This skill supports a wide range of formats including SMILES strings, SDF (Structure Data File), FASTA for protein sequences, and even molecular images or JSON datasets.
