bert-base-cased-DA-ChemTok-ZN1540K-V1

This model is a domain-adapted version of bert-base-cased on the cafierom/ZN1540K dataset of drug or drug-like molecules.

Model description

This domain adaptation of bert-base-cased has been trained on ~41K molecular SMILES strings, with added tokens:

new_tokens = ["[C@H]","[C@@H]","(F)","(Cl)","c1","c2","(O)","N#C","(=O)","([N+]([O-])=O)","[O-]"]

It is meant to be used for finetuning classification models for drug-related tasks.
