  • To accelerate the discovery and development of novel antiviral peptides (AVPs).
  • To create a robust benchmark dataset for AVP prediction.

Main Methods:

  • Constructed a novel benchmark dataset by integrating public databases and literature.
  • Developed the iAVP-RFVOT model using BLOSUM62 features, UMAP embedding, and differential entropy.
  • Applied rigorous feature engineering, data rebalancing, and an ensemble random forest classifier.

Main Results:

  • Achieved 87.6% 5-fold cross-validation accuracy and a Matthew's correlation coefficient (MCC) of 0.753.
  • Demonstrated 85.8% predictive accuracy and an MCC of 0.519 on an independent test set.
  • Outperformed existing state-of-the-art (SOTA) models in AVP prediction.

Conclusions:
