Schematic of the documented input, computation and output; not an executable configuration.
Non-overlapping DNA 4-mers enter four transformer layers. Masked-token pretraining uses barcode sequences, with random offsets to reduce tokenisation sensitivity. Average pooling produces a barcode embedding. The linked evaluation compares embeddings by cosine similarity to assign a genus from the nearest reference.
