HViLM

A foundation model for viral genomes that predicts pathogenicity, transmissibility and host tropism directly from sequence, released with the HVUE benchmark.

mSystems, accepted Built on DNABERT-2
3prediction tasks: pathogenicity, transmissibility, host tropism
92.4accuracy on held-out pathogenicity test set
91.3F1 for pathogenicity
83.1MCC for pathogenicity

Why it matters

Knowing whether a newly sequenced virus could cause disease, spread between people or infect human cells helps prioritize surveillance and research. HViLM learns these traits from the genome sequence itself.

How it works

  1. Pre-train. HViLM-base continues pre-training from DNABERT-2 on viral genomes.
  2. Fine-tune. Task-specific models are fine-tuned for pathogenicity, transmissibility and host tropism.
  3. Benchmark. HVUE provides standardized train and test splits for all three tasks so viral models can be compared fairly.
