MSCL-DTI: Multi-Modal Supervised Contrastive Learning for Drug-Target Interaction Prediction
Bibliographic record
Abstract
The identification of drug-target interactions (DTIs) is a key step in drug discovery, but existing models lack sufficient generalization and robustness when processing data from diverse sources with inconsistent distributions. To address this problem, we propose MSCL-DTI: a novel dual-channel supervised contrastive learning framework for DTI prediction. The model integrates sequence-based and structure-based multi-source joint representations. These features are aggregated via a fusion module and jointly optimized under the guidance of a supervised contrastive learning objective, ultimately forming a unified and highly discriminative latent representation. Extensive experiments demonstrate that MSCL-DTI outperforms baseline models in both performance and generalization. Furthermore, the model was successfully applied to screen drugs for the SARS-CoV-2 Spike protein, proving it to be an effective tool for discovering potential targeted drugs. Data and code are available at https://github.com/HelloJie14492IMSCL-DTI.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
