IALE: Imitating Active Learner Ensembles [article]

Christoffer Löffler, Christopher Mutschler
2020 arXiv   pre-print
We use DAGGER to train the policy on a dataset and later apply it to datasets from similar domains.  ...  However, the performance of AL heuristics depends on the structure of the underlying classifier model and the data.  ...  Since these states are the same for CNN and Resnet-18 classifiers (independant of the datasets) we can transfer a policy trained using a Resnet-18 classifier to a CNN classifier and vice versa.  ...
