Show abstract
Accurate prediction of the phages that target a bacterial host plays an important role in combating anti-microbial resistance. Our work explores the power of deep neural networks, convolutional neural networks, and pre-trained large DNA/protein language models to predict the host for a given phage. This work mainly uses the data provided by Gonzales et al. that contains receptor-binding protein sequences of the phages and the target host genus. We used pre-trained language models to obtain the dense representations of protein/nucleotide sequences to train a deep neural network to predict the target host genus. Additionally, convolutional neural networks were trained on one-hot encoding of nucleotide sequences to predict the target host genus. We achieved a weighted F1-score of 73.76% outperforming state-of-the-art models with an improvement of around 11% by using the protein language model ESM-1b.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
