Transformer is the state-of-the-art model in recent machine translation evaluations. Two strands of research are promising to improve models this kind: first uses wide networks (a.k.a. Transformer-Big) and has been de facto standard for development system, other deeper language representation but faces difficulty arising from learning deep networks. Here, we continue line on latter. We claim that a truly can surpass Transformer-Big counterpart by 1) proper use layer normalization 2) novel...

Spoken Language Understanding (SLU), which typically involves intent determination and slot filling, is a core component of spoken dialogue systems. Joint learning has shown to be effective in SLU given that tags intents are supposed share knowledge with each other. However, most existing joint methods only consider by sharing parameters on surface level rather than semantic level. In this work, we propose novel self-attentive model gate mechanism fully utilize the correlation between...

Multimodal summarization with multimodal output (MSMO) is to generate a summary for news report, which has been proven effectively improve users' satisfaction. The existing MSMO methods are trained by the target of text modality, leading modality-bias problem that ignores quality model-selected image during training. To alleviate this problem, we propose objective function guidance reference use loss from generation and selection. Due lack data, present two strategies, i.e., ROUGE-ranking...

In encoder-decoder neural models, multiple encoders are in general used to represent the contextual information addition individual sentence. this paper, we investigate multi-encoder approaches document-level machine translation (NMT). Surprisingly, find that context encoder does not only encode surrounding sentences but also behaves as a noise generator. This makes us rethink real benefits of context-aware - some improvements come from robust training. We compare several methods introduce...

Sentiment analysis has now become a popular research problem to tackle in NLP field. However, there are very few researches conducted on sentiment for Chinese. Progress is held back due lack of large and labelled corpus powerful models. To remedy this deficiency, we build Chinese Treebank over social data. It concludes 13550 labeled sentences which from movie reviews. Furthermore, introduce novel Recursive Neural Deep Model (RNDM) predict label based recursive deep learning. We consider the...

To improve the classification performance for Chinese short text with automatic semantic feature selection, in this paper we propose Hybrid Attention Networks (HANs) which combines word- and character-level selective attentions. The model firstly applies RNN CNN to extract features of texts. Then it captures class-related attentive representation from features. Finally, all are concatenated fed into output layer classification. Experimental results on 32-class 5-class datasets show that, our...

With the booming of content "re-creation" in social media platforms, character-orientedvideo summary has become a crucial form user-generated video content. However, artificial extraction could be time-consuming with high missing rate, while traditional techniques on person search may incur heavy burden computing resources. At same time, videos are usually accompanied rich textual information, e.g., subtitles or bullet-screen comments which provide multi-view description videos. Thus, there...

Currently, as a basic task of military document information extraction, Named Entity Recognition (NER) for documents has received great attention. In 2020, China Conference on Knowledge Graph and Semantic Computing (CCKS) System Engineering Research Institute Academy Military Sciences (AMS) issued the NER test evaluation, which requires recognition four types entities including Test Elements (TE), Performance Indicators (PI), Components (SC) Task Scenarios (TS). Due to particularity...

In recent years, the generation of conversation content based on deep neural networks has attracted many researchers. However, traditional language models tend to generate general replies, lacking logical and emotional factors. This paper proposes a model that combines reinforcement learning with editing constraints more meaningful customizable replies. The divides replies into three clauses pre-generated keywords uses editor further optimize final reply. multi-task multiple indicator...

Neural architecture search (NAS) has advanced significantly in recent years but most NAS systems restrict to learning architectures of a recurrent or convolutional cell. In this paper, we extend the space NAS. particular, present general approach learn both intra-cell and inter-cell (call it ESS). For better result, design joint method perform simultaneously. We implement our model differentiable system. neural language modeling, outperforms strong baseline on PTB WikiText data, with new...
