Derify/ChemRanker-alpha-qed-sim

This Cross Encoder is finetuned from Derify/ModChemBERT-IR-BASE using hard-negative triplets derived from Derify/pubchem_10m_genmol_similarity. Positive SMILES pairs are first filtered by quality and similarity constraints, then reduced to one strongest positive target per anchor molecule to create a high-signal training set for reranking. The model computes relevance scores for pairs of SMILES strings, enabling SMILES reranking and molecular semantic search.

For this variant, the positives are selected with a composite ranking criterion that combines high QED and similarity without an additional similarity-contribution cutoff. The quality stage uses strict inequality filtering (QED > 0.85, similarity > 0.5, with similarity also bounded below 1.0), and then keeps the top-scoring pair per anchor molecule.

Hard negatives are mined with Sentence Transformers using Derify/ChemMRL-beta as the teacher model and a TopK-PercPos-style margin setting based on NV-Retriever, with relative_margin=0.05 and max_negative_score_threshold = pos_score * percentage_margin. Training uses triplet-format samples with 5 mined negatives per anchor-positive pair and optimizes a multiple-negatives ranking objective, while reranking evaluation uses n-tuple samples with 30 mined negatives per query.

Usage

Direct Usage (Sentence Transformers)

First install the Transformers and Sentence Transformers libraries:

pip install -U "transformers>=4.57.1,<5.0.0"
pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("Derify/ChemRanker-alpha-qed-sim")
# Get scores for pairs of texts
pairs = [
    ['c1snnc1C[NH2+]Cc1cc2c(s1)CCC2', 'c1snnc1CCC[NH2+]Cc1cc2c(s1)CCC2'],

scores = model.predict(pairs)
print(scores.shape)
# (5,)
