 On every task, for every metric we compute test for statistical significance at α=0.05, i.e., the probability that performance model A is equal to the performance model B is estimated to be less then 0.05.
 We use the following tests, with varying statistical power:
 - accuracy and exact-match: one-tailed paired t-test,
-- average area under the curve: bayesian test inspired with (Goutte et al., 2005)[https://link.springer.com/chapter/10.1007/978-3-540-31865-1_25],
