From: Viral genomic features predict Orthopoxvirus reservoir hosts
Model accuracy was evaluated by (a) area under the receiver operating characteristic curve, (b) sensitivity and (c) specificity. Link prediction models were trained on known host-virus links as the response variable but differed in the inclusion versus exclusion of viral genomic traits as predictors. Host prediction models were trained on RT-PCR positivity (i.e., host exposure model) versus virus isolation data (i.e., susceptible host model). All models were trained on 100 random splits of training (70%) and test (30%) data.
