Weighted F1 scores after integrating the top <i>n</i> handcrafted sequence properties to the vector representations of the receptor-binding proteins.

The selected sequence properties are those with the highest Gini importance after training the phage-host interaction prediction tool by Boeckaerts et al. [15] on our dataset. These properties (in order of decreasing importance) are the A nucleotide frequency, GC content, C nucleotide frequency, TTA codon frequency, and TTA codon usage bias. The header row refers to the confidence thresholds at which we evaluated model performance.
