... contempo- rary unlabeled data contributes to its correct clas- sification in the test set. 5.2 Is more older unlabeled data better? The second question we addressed was whether having more older unlabeled data ... data. Furthermore, we will also show that augmenting the unlabeled data with older data in most cases does not re- sult in better performance than simply us- ing a smaller amount of current unlabeled data. 1 ... trained with older data. First, we studied whether it was better to update the seeds or the unlabeled data; then, we analyzed whether using a smaller amount of current unlabeled data could be better...
