Caption Generation of Robot Behaviors based on Unsupervised Learning of Action Segments

no code implementations23 Mar 2020 Koichiro Yoshino, Kohei Wakimoto, Yuta Nishimura, Satoshi Nakamura

Two reasons make it challenging to apply existing sequence-to-sequence models to this mapping: 1) it is hard to prepare a large-scale dataset for any kind of robots and their environment, and 2) there is a gap between the number of samples obtained from robot action observations and generated word sequences of captions.

Multi-Source Neural Machine Translation with Missing Data

no code implementations WS 2018 Yuta Nishimura, Katsuhito Sudoh, Graham Neubig, Satoshi Nakamura

This study focuses on the use of incomplete multilingual corpora in multi-encoder NMT and mixture of NMT experts and examines a very simple implementation where missing source translations are replaced by a special symbol <NULL>.
