Extending the Subwording Model of Multilingual Pretrained Models for New Languages

1 code implementation29 Nov 2022 Kenji Imamura, Eiichiro Sumita

Multilingual pretrained models are effective for machine translation and cross-lingual processing because they contain multiple languages in one model.

Recycling a Pre-trained BERT Encoder for Neural Machine Translation

no code implementations WS 2019 Kenji Imamura, Eiichiro Sumita

In this paper, a pre-trained Bidirectional Encoder Representations from Transformers (BERT) model is applied to Transformer-based neural machine translation (NMT).

Exploiting Out-of-Domain Parallel Data through Multilingual Transfer Learning for Low-Resource Neural Machine Translation

1 code implementation WS 2019 Aizhan Imankulova, Raj Dabre, Atsushi Fujita, Kenji Imamura

This paper proposes a novel multilingual multistage fine-tuning approach for low-resource neural machine translation (NMT), taking a challenging Japanese--Russian pair for benchmarking.

Constructing a Class-Based Lexical Dictionary using Interactive Topic Models

no code implementations LREC 2012 Kugatsu Sadamitsu, Kuniko Saito, Kenji Imamura, Yoshihiro Matsuo

This paper proposes a new method of constructing arbitrary class-based related word dictionaries on interactive topic models; we assume that each class is described by a topic.
