Multimodal Machine Translation (MMT) focuses on enhancing text-only translation with visual features, which has attracted considerable attention from both natural language processing and computer vision communities. Recent advances still struggle to train a separate model for each language pair, which is costly and unaffordable when the number of languages increases in the real world. In other words, the multilingual multimodal machine translation (Multilingual MMT) task has not been investigated, which aims to handle the aforementioned issues by providing a shared semantic space for multiple languages. Besides, the image modality has no language boundaries, which is superior to bridging the semantic gap between languages. To this end, we first propose the Multilingual MMT task by establishing two new Multilingual MMT benchmark datasets covering seven languages. Then, an effective baseline LVP-M3 using visual prompts is proposed to support translations between different languages, which includes three stages (token encoding, language-aware visual prompt generation, and language translation). Extensive experimental results on our constructed benchmark datasets demonstrate the effectiveness of LVP-M3 method for Multilingual MMT.

One of the major challenges of machine translation (MT) is ambiguity, which can in some cases be resolved by accompanying context such as an image. However, recent work in multimodal MT (MMT) has shown that obtaining improvements from images is challenging, limited not only by the difficulty of building effective cross-modal representations but also by the lack of specific evaluation and training data. We present a new MMT approach based on a strong text-only MT model, which uses neural adapters and a novel guided self-attention mechanism and which is jointly trained on both visual masking and MMT. We also release CoMMuTE, a Contrastive Multilingual Multimodal Translation Evaluation dataset, composed of ambiguous sentences and their possible translations, accompanied by disambiguating images corresponding to each translation. Our approach obtains competitive results over strong text-only models on standard English-to-French benchmarks and outperforms these baselines and state-of-the-art MMT systems with a large margin on our contrastive test set.

Recent cross-lingual cross-modal works attempt to extend Vision-Language Pre-training (VLP) models to non-English inputs and achieve impressive performance. However, these models focus only on understanding tasks utilizing encoder-only architecture. In this paper, we propose ERNIE-UniX2, a unified cross-lingual cross-modal pre-training framework for both generation and understanding tasks. ERNIE-UniX2 integrates multiple pre-training paradigms (e.g., contrastive learning and language modeling) based on encoder-decoder architecture and attempts to learn a better joint representation across languages and modalities. Furthermore, ERNIE-UniX2 can be seamlessly fine-tuned for varieties of generation and understanding downstream tasks. Pre-trained on both multilingual text-only and image-text datasets, ERNIE-UniX2 achieves SOTA results on various cross-lingual cross-modal generation and understanding tasks such as multimodal machine translation and multilingual visual question answering.

Pre-trained models have achieved remarkable success in natural language processing (NLP). However, existing pre-training methods underutilize the benefits of language understanding for generation. Inspired by the idea of Generative Adversarial Networks (GANs), we propose a GAN-style model for encoder-decoder pre-training by introducing an auxiliary discriminator, unifying the ability of language understanding and generation in a single model. Our model, named as GanLM, is trained with two pre-training objectives: replaced token detection and replaced token denoising. Specifically, given masked source sentences, the generator outputs the target distribution and the discriminator predicts whether the target sampled tokens from distribution are incorrect. The target sentence is replaced with misclassified tokens to construct noisy previous context, which is used to generate the gold sentence. In general, both tasks improve the ability of language understanding and generation by selectively using the denoising data. Extensive experiments in language generation benchmarks show that GanLM with the powerful language understanding capability outperforms various strong pre-trained language models (PLMs) and achieves state-of-the-art performance.

以前的工作主要侧重于改善NLU任务的交叉传输,具有多语言预用编码器(MPE),或提高与伯特的监督机器翻译的性能。然而,探索了,MPE是否可以有助于促进NMT模型的交叉传递性。在本文中,我们专注于NMT中的零射频转移任务。在此任务中,NMT模型培训,只有一个语言对的并行数据集和搁置架MPE,然后它直接测试在零拍语言对上。我们为此任务提出了Sixt,一个简单而有效的模型。 SIXT利用了两阶段培训计划利用MPE,并进一步改进了解离编码器和容量增强的解码器。使用此方法,SIMPT显着优于MBart,这是一个用于NMT的预磨削的多语言编码器解码器模型,平均改善了14个源语言的零拍摄的任何英语测试集上的7.1 BLEU。此外,培训计算成本和培训数据较少,我们的模型在15个任何英语测试组上实现了比Criss和M2M-100,两个强大的多语言NMT基线更好的性能。

尽管最近在跨模式检索领域取得了进展,但由于缺乏手动注释的数据集,研究的重点较少。在本文中,我们提出了一种用于低资源语言的噪声跨语法跨模式检索方法。为此,我们使用机器翻译(MT)来构建低资源语言的伪并行句子对。但是,由于MT并不完美,因此它倾向于在翻译过程中引入噪音,从而使文本嵌入被损坏,从而损害了检索性能。为了减轻这一点,我们引入了一种多视图自我验证方法来学习噪声稳定目标语言表示,该方法采用了跨注意模块来生成软伪靶标,以从基于相似性的视图和功能 - 功能 - 基于视图。此外,受到无监督的MT的反向翻译的启发,我们最大程度地减少了原点句子和反翻译句子之间的语义差异,以进一步提高文本编码器的噪声稳健性。在三个视频文本和图像文本跨模式检索基准跨不同语言上进行了广泛的实验,结果表明,我们的方法显着改善了整体性能,而无需使用额外的人体标记数据。此外,从最近的视觉和语言预训练框架(即剪辑)中配备了预训练的视觉编码器,我们的模型可实现显着的性能增长,这表明我们的方法与流行的预训练模型兼容。代码和数据可在https://github.com/huiguanlab/nrccr上找到。

最近,多模式机器翻译(MMT)的研究激增,其中其他模式(例如图像)用于提高文本系统的翻译质量。这种多模式系统的特殊用途是同时机器翻译的任务,在该任务中,已证明视觉上下文可以补充源句子提供的部分信息,尤其是在翻译的早期阶段。在本文中,我们提出了第一个基于变压器的同时MMT体系结构,该体系结构以前尚未在现场探索过。此外,我们使用辅助监督信号扩展了该模型,该信号使用标记的短语区域比对来指导其视觉注意机制。我们在三个语言方向上进行全面的实验,并使用自动指标和手动检查进行彻底的定量和定性分析。我们的结果表明,(i)监督视觉注意力一致地提高了MMT模型的翻译质量,并且(ii)通过监督损失对MMT进行微调,比从SCRATCH训练MMT的MMT可以提高性能。与最先进的模型相比,我们提出的模型可实现多达2.3 bleu和3.5 Meteor点的改善。

This paper demonstrates that multilingual denoising pre-training produces significant performance gains across a wide variety of machine translation (MT) tasks. We present mBART -a sequence-to-sequence denoising auto-encoder pre-trained on large-scale monolingual corpora in many languages using the BART objective . mBART is the first method for pre-training a complete sequence-to-sequence model by denoising full texts in multiple languages, while previous approaches have focused only on the encoder, decoder, or reconstructing parts of the text. Pre-training a complete model allows it to be directly fine tuned for supervised (both sentence-level and document-level) and unsupervised machine translation, with no task-specific modifications. We demonstrate that adding mBART initialization produces performance gains in all but the highest-resource settings, including up to 12 BLEU points for low resource MT and over 5 BLEU points for many document-level and unsupervised models. We also show it also enables new types of transfer to language pairs with no bi-text or that were not in the pre-training corpus, and present extensive analysis of which factors contribute the most to effective pre-training.

Multimodal machine translation (MMT) aims to improve translation quality by incorporating information from other modalities, such as vision. Previous MMT systems mainly focus on better access and use of visual information and tend to validate their methods on image-related datasets. These studies face two challenges. First, they can only utilize triple data (bilingual texts with images), which is scarce; second, current benchmarks are relatively restricted and do not correspond to realistic scenarios. Therefore, this paper correspondingly establishes new methods and new datasets for MMT. First, we propose a framework 2/3-Triplet with two new approaches to enhance MMT by utilizing large-scale non-triple data: monolingual image-text data and parallel text-only data. Second, we construct an English-Chinese {e}-commercial {m}ulti{m}odal {t}ranslation dataset (including training and testing), named EMMT, where its test set is carefully selected as some words are ambiguous and shall be translated mistakenly without the help of images. Experiments show that our method is more suitable for real-world scenarios and can significantly improve translation performance by using more non-triple data. In addition, our model also rivals various SOTA models in conventional multimodal translation benchmarks.

We present a new approach to perform zero-shot cross-modal transfer between speech and text for translation tasks. Multilingual speech and text are encoded in a joint fixed-size representation space. Then, we compare different approaches to decode these multimodal and multilingual fixed-size representations, enabling zero-shot translation between languages and modalities. All our models are trained without the need of cross-modal labeled translation data. Despite a fixed-size representation, we achieve very competitive results on several text and speech translation tasks. In particular, we significantly improve the state-of-the-art for zero-shot speech translation on Must-C. Incorporating a speech decoder in our framework, we introduce the first results for zero-shot direct speech-to-speech and text-to-speech translation.

通过多种语言对培训的多语言神经机器翻译(MNMT),由于模型参数的较少和较低的培训成本,通过在多种语言之间共享知识,引起了人们的关注。尽管如此,由于不同翻译方向之间的负面干扰,尤其是在高资源语言上,因此,多语言培训在共享参数中受到语言干扰退化的困扰。在本文中,我们提出了具有高资源语言特定培训(HLT-MT)的多语言翻译模型,以减轻负面干扰,该干扰采用了具有特定于语言的选择机制的两阶段培训。具体而言,我们首先仅使用高资源对训练多语言模型,然后选择解码器顶部的语言特定模块,以增强高资源方向的翻译质量。接下来,对所有可用语料库进行进一步培训,将知识从高资源语言(HRLS)转移到低资源语言(LRLS)。实验结果表明,HLT-MT在WMT-10和Opus-100基准测试上的表现优于各种强基础。此外,分析实验验证了我们方法在减轻多语言训练中负面干扰方面的有效性。

Universal cross-lingual sentence embeddings map semantically similar cross-lingual sentences into a shared embedding space. Aligning cross-lingual sentence embeddings usually requires supervised cross-lingual parallel sentences. In this work, we propose mSimCSE, which extends SimCSE to multilingual settings and reveal that contrastive learning on English data can surprisingly learn high-quality universal cross-lingual sentence embeddings without any parallel data. In unsupervised and weakly supervised settings, mSimCSE significantly improves previous sentence embedding methods on cross-lingual retrieval and multilingual STS tasks. The performance of unsupervised mSimCSE is comparable to fully supervised methods in retrieving low-resource languages and multilingual STS. The performance can be further enhanced when cross-lingual NLI data is available. Our code is publicly available at https://github.com/yaushian/mSimCSE.

Pre-trained multilingual language models show significant performance gains for zero-shot cross-lingual model transfer on a wide range of natural language understanding (NLU) tasks. Previously, for zero-shot cross-lingual evaluation, pre-trained models are only fine-tuned on English data and tested on a variety of target languages. In this paper, we do cross-lingual evaluation on various NLU tasks (sentence classification, sequence labeling, question answering) using prompt-tuning and compare it with fine-tuning. The results show that prompt tuning achieves much better cross-lingual transfer than fine-tuning across datasets, with only 0.1% to 0.3% tuned parameters. Additionally, we demonstrate through the analysis that prompt tuning can have better cross-lingual transferability of representations on downstream tasks with better aligned decision boundaries.
