What is polyBERT?
polyBERT is a revolutionary chemical language model specifically designed for polymer informatics. It represents a significant advancement in the field by enabling fully machine-driven ultrafast polymer analysis. The model's primary function is to convert PSMILES strings (polymer-specific SMILES notation) into 600-dimensional dense fingerprints that numerically represent polymer chemical structures.
Implementation Details
The model is built on the DeBERTa-v2 architecture and can be easily implemented using either sentence-transformers or HuggingFace Transformers libraries. It employs mean pooling operations on contextualized word embeddings and supports a maximum sequence length of 512 tokens.
