Table 1 Cross-tabulation between mouse strains and IAV subtypes in the MIVir ×I IP (MIV) dataset. The number at the top in each cell corresponds to the number of records of relevant infections, and its breakdown into high, intermediate and low virulence cases for the three-class classification problems are shown in order in parenthesis. The number of virulent cases for the two-class classification problems is the sum of the number of high and intermediate virulence cases, while the number of avirulent cases equals to the number of low virulence cases
