HViLM
A foundation model for viral genomes that predicts pathogenicity, transmissibility and host tropism directly from sequence, released with the HVUE benchmark.
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
- Pre-train. HViLM-base continues pre-training from DNABERT-2 on viral genomes.
- Fine-tune. Task-specific models are fine-tuned for pathogenicity, transmissibility and host tropism.
- Benchmark. HVUE provides standardized train and test splits for all three tasks so viral models can be compared fairly.
Models
| Model | Task |
|---|---|
| HViLM-base | Pre-trained viral genome model |
| HViLM-Patho | Pathogenic vs non-pathogenic |
| HViLM-R0 | Transmissibility |
| HViLM-Tropism | Human-tropic vs non-human-tropic |
