This online classifier is initially trained using a small set of examples, and then updated over time using streaming data that are interactively labeled by a user or pseudo-labeled by a soft-labeling technique. We prove, theoretically, that this yields the same model as training a DA classifier via full batch learning. We then provide experimental evidence that our approach improves the performance of DA classifiers and is robust to mislabeled data, and that our soft-labeling technique has better performance than existing state-of-the-art methods. We argue that our proposal is suitable for real-time applications, as its time complexity w.r.t. the streaming data remains constant.}, number={6}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Jaramillo-Yanez, Andres G and Benalcázar, Marco E. and Sardina, Sebastian and Zambetta, Fabio}, year={2022}, month={Jun.}, pages={6996-7004} }
