ML-calculated feature importance map and important Raman ranges for classifying three types of avian viruses: IBV coronavirus, avian FLUA virus, and reovirus. Feature important maps and matching scores are given for each avian virus type. The matching score for RBD protein only applies when correlating with IBV coronavirus because RBD protein is an exclusive biomolecule in IBV. (SI Appendix, Fig. S2 includes matching scores with more functional groups.)
