Future work sentences (FWS) are the particular sentences in academic papers that contain the author's description of their proposed follow-up research direction. This paper presents methods to automatically extract FWS from academic papers and classify them according to the different future directions embodied in the paper's content. FWS recognition methods will enable subsequent researchers to locate future work sentences more accurately and quickly and reduce the time and cost of acquiring the corpus. The current work on automatic identification of future work sentences is relatively small, and the existing research cannot accurately identify FWS from academic papers, and thus cannot conduct data mining on a large scale. Furthermore, there are many aspects to the content of future work, and the subdivision of the content is conducive to the analysis of specific development directions. In this paper, Nature Language Processing (NLP) is used as a case study, and FWS are extracted from academic papers and classified into different types. We manually build an annotated corpus with six different types of FWS. Then, automatic recognition and classification of FWS are implemented using machine learning models, and the performance of these models is compared based on the evaluation metrics. The results show that the Bernoulli Bayesian model has the best performance in the automatic recognition task, with the Macro F1 reaching 90.73%, and the SCIBERT model has the best performance in the automatic classification task, with the weighted average F1 reaching 72.63%. Finally, we extract keywords from FWS and gain a deep understanding of the key content described in FWS, and we also demonstrate that content determination in FWS will be reflected in the subsequent research work by measuring the similarity between future work sentences and the abstracts.

随着文献资源的丰富，研究人员面临着信息爆炸和知识过载的不断增长的问题。为了帮助学者检索文学并成功获得知识，澄清学术文学中内容的语义结构已成为基本的研究问题。在识别学术文章中章节的结构功能的研究中，只有几项研究使用了深度学习模型，并探索了特征输入的优化。这限制了研究任务深度学习模型的应用，优化潜力。本文将ACL会议的文章作为语料库。我们采用传统的机器学习模型和深度学习模型，基于各种特征输入构建分类器。实验结果表明，（1）与章节内容相比，章节标题更有利于识别学术文章的结构功能。 （2）相对位置是建立传统模型的有价值的功能。 （3）受到（2）的启发，本文进一步将上下文信息引入深度学习模型，取得了显着的结果。同时，我们的模型在包含200个采样的非训练样本的开放式测试中显示出良好的迁移能力。近五年我们还基于表演模型的最佳实践，并对整体语料库进行了时间序列分析，近五年注释了ACL主要会议文件。这项工作通过多个比较实验探索并总结了此任务的实际功能和模型，并为相关文本分类任务提供了参考。最后，我们表示当前模型的局限性和缺点以及进一步优化的方向。

Person re-identification plays a significant role in realistic scenarios due to its various applications in public security and video surveillance. Recently, leveraging the supervised or semi-unsupervised learning paradigms, which benefits from the large-scale datasets and strong computing performance, has achieved a competitive performance on a specific target domain. However, when Re-ID models are directly deployed in a new domain without target samples, they always suffer from considerable performance degradation and poor domain generalization. To address this challenge, we propose a Deep Multimodal Fusion network to elaborate rich semantic knowledge for assisting in representation learning during the pre-training. Importantly, a multimodal fusion strategy is introduced to translate the features of different modalities into the common space, which can significantly boost generalization capability of Re-ID model. As for the fine-tuning stage, a realistic dataset is adopted to fine-tune the pre-trained model for better distribution alignment with real-world data. Comprehensive experiments on benchmarks demonstrate that our method can significantly outperform previous domain generalization or meta-learning methods with a clear margin.

联合检测（COSOD）旨在从多个图像发现重复的显着物体。两个主要挑战是组语义提取和噪声对象抑制。在本文中，我们提出了COSOD的统一两阶段的语义传播和对比度学习网络（主题网络）。主题网络可以分解为两个子结构，包括两个阶段的语义传播模块（TGSP），以应对第一个挑战和对比度学习模块（CLM），以应对第二个挑战。具体来说，对于TGSP，我们设计了一个图像到群体传播模块（IGP）来捕获组内相似特征的共识表示和小像素传播模块（GPP），以构建共识表示的相关性。对于CLM，随着阳性样品的设计，语义一致性得到了增强。通过设计负样品的设计，噪声对象被抑制。关于三个主要基准测试的实验结果表明，主题网络在各种评估指标方面都优于其他竞争对手。

推荐系统（RS）是一个重要的在线应用程序，每天都会影响数十亿个用户。主流RS排名框架由两个部分组成：多任务学习模型（MTL），该模型可预测各种用户反馈，即点击，喜欢，分享和多任务融合模型（MTF），该模型（MTF）结合了多任务就用户满意度而言，输出分为最终排名得分。关于融合模型的研究并不多，尽管它对最终建议作为排名的最后一个关键过程有很大的影响。为了优化长期用户满意度，而不是贪婪地获得即时回报，我们将MTF任务作为Markov决策过程（MDP），并在推荐会话中提出，并建议基于批处理加固学习（RL）基于多任务融合框架（BATCHRL-MTF）包括批处理RL框架和在线探索。前者利用批处理RL从固定的批处理数据离线学习最佳推荐政策，以达到长期用户满意度，而后者则探索了潜在的高价值动作在线，以突破本地最佳难题。通过对用户行为的全面调查，我们通过从用户粘性和用户活动性的两个方面的微妙启发式方法对用户满意度进行了建模。最后，我们对十亿个样本级别的现实数据集进行了广泛的实验，以显示模型的有效性。我们建议保守的离线政策估计器（保守 - 访问器）来测试我们的模型离线。此外，我们在真实推荐环境中进行在线实验，以比较不同模型的性能。作为成功在MTF任务中应用的少数批次RL研究之一，我们的模型也已部署在一个大规模的工业短视频平台上，为数亿用户提供服务。

Pretraining is a dominant paradigm in computer vision. Generally, supervised ImageNet pretraining is commonly used to initialize the backbones of person re-identification (Re-ID) models. However, recent works show a surprising result that CNN-based pretraining on ImageNet has limited impacts on Re-ID system due to the large domain gap between ImageNet and person Re-ID data. To seek an alternative to traditional pretraining, here we investigate semantic-based pretraining as another method to utilize additional textual data against ImageNet pretraining. Specifically, we manually construct a diversified FineGPR-C caption dataset for the first time on person Re-ID events. Based on it, a pure semantic-based pretraining approach named VTBR is proposed to adopt dense captions to learn visual representations with fewer images. We train convolutional neural networks from scratch on the captions of FineGPR-C dataset, and then transfer them to downstream Re-ID tasks. Comprehensive experiments conducted on benchmark datasets show that our VTBR can achieve competitive performance compared with ImageNet pretraining - despite using up to 1.4x fewer images, revealing its potential in Re-ID pretraining.

人重新识别（RE-ID）在公共安全和视频监控等应用中起着重要作用。最近，从合成数据引擎的普及中获益的合成数据学习，从公众眼中引起了极大的关注。但是，现有数据集数量，多样性和变性有限，并且不能有效地用于重新ID问题。为了解决这一挑战，我们手动构造一个名为FineGPR的大型人数据集，具有细粒度的属性注释。此外，旨在充分利用FineGPR的潜力，并推广从数百万综合数据的高效培训，我们提出了一个名为AOST的属性分析流水线，它动态地学习了真实域中的属性分布，然后消除了合成和现实世界之间的差距因此，自由地部署到新场景。在基准上进行的实验表明，FineGPR具有AOST胜过（或与）现有的实际和合成数据集，这表明其对重新ID任务的可行性，并证明了众所周知的较少的原则。我们的Synthetic FineGPR数据集可公开可用于\ URL {https://github.com/jeremyxsc/finegpr}。

In this paper, we propose a robust 3D detector, named Cross Modal Transformer (CMT), for end-to-end 3D multi-modal detection. Without explicit view transformation, CMT takes the image and point clouds tokens as inputs and directly outputs accurate 3D bounding boxes. The spatial alignment of multi-modal tokens is performed implicitly, by encoding the 3D points into multi-modal features. The core design of CMT is quite simple while its performance is impressive. CMT obtains 73.0% NDS on nuScenes benchmark. Moreover, CMT has a strong robustness even if the LiDAR is missing. Code will be released at https://github.com/junjie18/CMT.

Knowledge graphs (KG) have served as the key component of various natural language processing applications. Commonsense knowledge graphs (CKG) are a special type of KG, where entities and relations are composed of free-form text. However, previous works in KG completion and CKG completion suffer from long-tail relations and newly-added relations which do not have many know triples for training. In light of this, few-shot KG completion (FKGC), which requires the strengths of graph representation learning and few-shot learning, has been proposed to challenge the problem of limited annotated data. In this paper, we comprehensively survey previous attempts on such tasks in the form of a series of methods and applications. Specifically, we first introduce FKGC challenges, commonly used KGs, and CKGs. Then we systematically categorize and summarize existing works in terms of the type of KGs and the methods. Finally, we present applications of FKGC models on prediction tasks in different areas and share our thoughts on future research directions of FKGC.
