Study questions progress in molecular representation learning, finds ECFP outperforms most neural models

A new study published on arXiv evaluated 28 pretrained molecular embedding models, including graph neural networks, text transformers, and hybrid architectures, across 25 classification datasets. The research found that most neural models, with the exception of CheMeleon, did not outperform the classical ECFP count fingerprint. Further validation on external datasets also showed no definitive advantage for either embedding method. The study concludes by recommending the evaluation of both ECFP fingerprints and CheMeleon embeddings for QSAR/QSPR studies and questions the perceived progress in molecular representation learning.

IMPACT Challenges the perceived progress in molecular representation learning and suggests a need for more rigorous evaluation standards.
