NTv2-50M-ms (ViroBench classification)

Evidence concern: excluded from comparisons

Table 25 prints one Macro-F1 per model for the taxonomy columns. For 143 of the 144 model-by-split taxonomy cells on the ALL-virus set, the printed value equals the mean of the five per-rank values in Table 26 rounded to two decimals. The exception is RNA-FM under the genus-disjoint split: Table 25 prints 48.67 and the mean of the Table 26 ranks (59.96, 65.35, 37.58, 58.78, 43.82) is 53.10. One of the two tables is wrong for that row, so RNA-FM ALL taxonomy G-Split should not be used in a comparison without checking the published code.ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks · Table 25, row 'RNA-FM', column 'ALL viruses / Taxonomy / G-Split'; Table 26, row 'RNA-FM'

Table 3 lists NT v3 under phage-specific pretraining coverage (P) and Table 9 lists it as non-viral (N). Table 25 groups the NTv3 rows under phage-specific coverage, which is what the configurations record. Pretraining coverage is the paper's main explanatory variable, so NT v3 rows should not be used to support a coverage-versus-performance claim.ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks · Table 3 row 'NT v3'; Table 9 row 'NT v3'; Table 25 section 'DNA Foundation Models (Phage-specific Coverage)'

NTv2-50M-ms, a configuration of Nucleotide Transformer v2: Frozen backbone; sequence embeddings from windows of 512, 1024 or 2048 bp fed to a standardised MLP head; pretraining coverage lineage: non-viral coverage.

For 143 of the 144 model-by-split taxonomy cells on the ALL-virus set, the printed value equals the mean of the five per-rank values in Table 26 rounded to two decimals. The exception is RNA-FM under the genus-disjoint split: Table 25 prints 48.67 and the mean of the Table 26 ranks (59.96, 65.35, 37.58, 58.78, 43.82) is 53.10. One of the two tables is wrong for that row, so RNA-FM ALL taxonomy G-Split should not be used in a comparison without checking the published code.ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks · Table 25, row 'RNA-FM', column 'ALL viruses / Taxonomy / G-Split'; Table 26, row 'RNA-FM' Table 3 lists NT v3 under phage-specific pretraining coverage (P) and Table 9 lists it as non-viral (N). Table 25 groups the NTv3 rows under phage-specific coverage, which is what the configurations record. Pretraining coverage is the paper's main explanatory variable, so NT v3 rows should not be used to support a coverage-versus-performance claim.ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks · Table 3 row 'NT v3'; Table 9 row 'NT v3'; Table 25 section 'DNA Foundation Models (Phage-specific Coverage)' Methods, coverage and source NTv2-50M-ms on ViroBench RNA viruses taxonomy classification (G-Split) lit-microbial-20261011-virobench-protocol-rna-taxonomy-g-split Aggregation: Not reported ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks · Table 25, row 'NTv2-50M-ms', column 'RNA viruses / Taxonomy / G-Split' (text-layer line 2597)

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Evidence table

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
