Statistical significance of pairs of methods

[debasmitdas]

In the tables, you compare all the methods in the conventional and generalized setting. So, is there any way to measure the statistical significance of pairs of methods ? In that case, over how many trials the averaged accuracy has been found ? If we know the accuracy results of different trials, I think we can we find the significance level (p-value). Or are they just evaluated on some fixed large batch of test dataset without any trials ?
