REZCR: A Zero-shot Character Recognition Method via Radical Extraction. (arXiv:2207.05842v1 [cs.CV])

The long-tail effect is a common issue that limits the performance of deep
learning models on real-world datasets. Character image dataset development is
also affected by such unbalanced data distribution due to differences in
character usage frequency. Thus, current character recognition methods are
limited when applying to real-world datasets, in particular to the character
categories in the tail which are lacking training samples, e.g., uncommon
characters, or characters from historical documents. In this paper, we propose
a zero-shot character recognition …
