HVUE v2: Human Virome Understanding Evaluation Benchmark

⚠️ This is version 2 of the HVUE benchmark. Version 1 (duttaprat/HVUE) contained train-test sequence overlap due to chunk-level random splitting before clustering. HVUE v2 corrects this with cluster-aware splitting and verified zero leakage. All v1 results should be considered superseded.

Overview

HVUE v2 is a rigorously constructed benchmark for evaluating DNA language models on three epidemiologically relevant viral prediction tasks:

1. Pathogenicity Classification — Distinguishing disease-causing from benign viral strains
2. Transmissibility Prediction — R₀-based classification (R₀ < 1 vs. R₀ ≥ 1)
3. Host Tropism Prediction — Identifying human-infecting viruses from non-human-tropic viruses

Six-Stage Pipeline

HVUE v2 eliminates train-test overlap through a six-stage pipeline:

1. Consolidation: Source genomes collected and deduplicated at genome level
2. MMseqs2 Clustering: Genomes clustered at 95% identity (standard) or 70% identity (hard)
3. Cluster-Aware Splitting: Train/val/test splits (70/15/15) at the cluster level — all sequences in a cluster go to the same split
4. Chunking: After splitting, genomes segmented into fixed-length windows (500/1000/2000 bp)
5. Deduplication: SHA-256 hash-based exact-match removal within splits
6. Leakage Audit: Automated verification of zero cross-split overlap

Key fix vs. v1: Version 1 chunked first, then split randomly. Version 2 splits at the cluster level first, then chunks.

CSV Format

Each CSV contains two columns:

• sequence: DNA sequence (A/T/G/C)
• label: Binary label (0 or 1)

Usage

import pandas as pd
from datasets import load_dataset

# Load a specific config
ds = load_dataset("duttaprat/HVUE-v2",
                  data_dir="Pathogenicity/standard_capped_1000bp",
                  data_files={"train": "train.csv", "validation": "dev.csv", "test": "test.csv"})

# Or load directly
train = pd.read_csv("Pathogenicity/standard_capped_1000bp/train.csv")

Leakage Audit

Zero exact-match or near-match overlap confirmed across all configurations. Audit scripts available at: https://github.com/duttaprat/HViLM
