Training-Free Neural Active Learning with Initialization-Robustness Guarantees

Apivich Hemachandra, Zhongxiang Dai, Jasraj Singh +2

Existing neural active learning algorithms have aimed to optimize the predictive performance of neural networks (NNs) by selecting data for labelling. However, other than a good pr…
