Predicting Interactions between Virus and Host Proteins Using Repeat Patterns and Composition of Amino Acids

Table 8

The number of host proteins shared by training (TR) and test (TS) datasets used for assessing the applicability of the SVM model to new viruses and to new hosts.

#Host proteins	499	424	499	27	499	307	499	298	499	1056
#Host proteins common to TR and TS	63 (14.9%)		5 (18.5%)		68 (22.1%)		22 (7.4%)		122 (11.6%)

The numbers in parentheses represent the proportion of common proteins to proteins in test datasets.
