On accuracy evaluation

[TomSang]

As I know F1 score is usually used for accuracy evaluation. But I don't know the following concepts,

In TestActivity.java,
double accuracy_reference = (double) matches_reference / (double) total_reference;
double accuracy_deviation = (double) matches_deviation / (double) total_deviation;
double robustness = accuracy_deviation / accuracy_reference;

Could you give out explanations on these concepts?

Hi @TomSang the F1 score was not used here, but the accuracy (top 1). The deviation and robustness was mostly used for internal purposes (to test specific test sets against each other).
