Zero-shot deep learning for the annotation of unknown eDNA sequences using co-occurrences and phylogenetic embeddings

Visualization of the learned embedding space after dimensionality reduction with the t-SNE algorithm.
Each point corresponds to a species in the tree, and its color represents its taxonomic order. Points are further distinguished with two different symbols based on whether the species is in the DNA reference database (dot) or not (cross). Axes are omitted because they do not carry an intrinsic meaning.
