(2016) proposed the label smoothing as a regularization technique to improve the accuracy of the Inception networks on ImageNet. By explicitly assigning a small probability to non-ground-truth labels, label smoothing can prevent the models from becoming too confident about the predictions, and thus improve generalization. It turned out to be a useful alternative to the standard cross entropy loss, and has been widely adopted to fight against the over-confidence (Zoph et al., 2018;Chorowski and Jaitly, 2017;Vaswani et al., 2017), improve the model calibration (Müller et al., 2019), and denoise incorrect labels (Lukasik et al., 2020)." }, { "file": "paper_46.txt", "start": 2844, "end": 2969, "label": "Unsupported claim", "user": "Ed", "text": "This is driven by the observation that entity boundaries are more ambiguous and inconsistent to annotate in NER engineering.
