bert-base-uncased-finetuned-HMGCR-IC50s-V3

This model is a fine-tuned version of bert-base-uncased on on 905 HMGCR IC50 values from bindingDB.org. Molecules with counter ions were included twice, once with and once without counter-ions.

It achieves the following results on the evaluation set:

Loss: 0.5183
Accuracy: 0.8500
F1: 0.8408

Use in Pipeline:

from transformers import pipeline

ic50_pipe = pipeline("text-classification", model="cafierom/bert-base-uncased-finetuned-HMGCR-IC50s-V3")

bert_ic50 = ic50_pipe('COC(=O)C[C@H](O)C[C@H](O)\C=C\n1c(cc(c1-c1ccc(F)cc1)-c1cccc(Br)c1)C(C)C')

#result: [{'label': '< 50 nM', 'score': 0.8461818695068359}]
