Tianlun Zheng, Zhineng Chen, BingChen Huang, Wei Zhang, Yu-Gang, Jiang

TL;DR
This paper introduces MRN, a novel incremental multilingual text recognition system that effectively handles new languages and mitigates catastrophic forgetting by using language-specific recognizers and a domain predictor.
Contribution
The paper proposes the Multiplexed Routing Network (MRN), a new approach for incremental multilingual text recognition that reduces reliance on old data and improves accuracy over existing methods.
Findings
MRN outperforms existing IL methods by 10.3% to 35.8% in accuracy.
MRN effectively mitigates catastrophic forgetting in incremental multilingual recognition.
The approach demonstrates strong results on MLT17 and MLT19 datasets.
Abstract
Multilingual text recognition (MLTR) systems typically focus on a fixed set of languages, which makes it difficult to handle newly added languages or adapt to ever-changing data distribution. In this paper, we propose the Incremental MLTR (IMLTR) task in the context of incremental learning (IL), where different languages are introduced in batches. IMLTR is particularly challenging due to rehearsal-imbalance, which refers to the uneven distribution of sample characters in the rehearsal set, used to retain a small amount of old data as past memories. To address this issue, we propose a Multiplexed Routing Network (MRN). MRN trains a recognizer for each language that is currently seen. Subsequently, a language domain predictor is learned based on the rehearsal set to weigh the recognizers. Since the recognizers are derived from the original data, MRN effectively reduces the reliance on…
