Regularizing Neural Machine Translation by Target-bidirectional Agreement
Although Neural Machine Translation (NMT) has achieved remarkable progress in
the past several years, most NMT systems still suffer from a fundamental
shortcoming as in other sequence generation tasks: errors made early in
generation process are fed as inputs to the model and can be quickly amplified,
harming subsequent sequence generation. To address this issue, we propose a
novel model regularization method for NMT training, which aims to improve the
agreement between translations generated by left-to-right (L2R) and
right-to-left (R2L) NMT decoders. This goal is achieved by introducing two
Kullback-Leibler divergence regularization terms into the NMT training
objective to reduce the mismatch between output probabilities of L2R and R2L
models. In addition, we also employ a joint training strategy to allow L2R and
R2L models to improve each other in an interactive update process. Experimental
results show that our proposed method significantly outperforms
state-of-the-art baselines on Chinese-English and English-German translation
tasks.Comment: Accepted by AAAI 201
Temporary Structures in Shangai EXPO2010 - Structural Design Specification and Example
p. 790-798Many temporary buildings and structures are constructed in the Expo Park, Shanghai as
pavilions and facilities of EXPO2010. New materials and new structural systems are
expected to be used and appear. The structural design specification for temporary structures of EXPO2010 is summarized and the structural design of Norwegian pavilion is described in this paper.Wu, M.; Meng, L.; Mu, T. (2010).
