Figure 2: F-measure over time for test set 98b with configurations: As can be seen, there is a small gain in performance by using seeds within the epoch of the test set, but the decay is still observable as we increase the time gap between the unlabeled data and the test set.
if we use unlabeled data within the epoch of the test set, we hardly see a degradation trend as the time gap between the epochs of seeds and test set is increased.
