Code intelligence leverages machine learning techniques to extract knowledge from extensive code corpora, with the aim of developing intelligent tools to improve the quality and productivity of computer programming. Currently, there is already a thriving research community focusing on code intelligence, with efforts ranging from software engineering, machine learning, data mining, natural language processing, and programming languages. In this paper, we conduct a comprehensive literature review on deep learning for code intelligence, from the aspects of code representation learning, deep learning techniques, and application tasks. We also benchmark several state-of-the-art neural models for code intelligence, and provide an open-source toolkit tailored for the rapid prototyping of deep-learning-based code intelligence models. In particular, we inspect the existing code intelligence models under the basis of code representation learning, and provide a comprehensive overview to enhance comprehension of the present state of code intelligence. Furthermore, we publicly release the source code and data resources to provide the community with a ready-to-use benchmark, which can facilitate the evaluation and comparison of existing and future code intelligence models (https://xcodemind.github.io). At last, we also point out several challenging and promising directions for future research.

Self-tuning is a feature of autonomic databases that includes the problem of automatic schema design. It aims at providing an optimized schema that increases the overall database performance. While in relational databases automatic schema design focuses on the automated design of the physical schema, in NoSQL databases all levels of representation are considered: conceptual, logical, and physical. This is mainly because the latter are mostly schema-less and lack a standard schema design procedure as is the case for SQL databases. In this work, we carry out a systematic literature survey on automatic schema design in both SQL and NoSQL databases. We identify the levels of representation and the methods that are used for the schema design problem, and we present a novel taxonomy to classify and compare different schema design solutions. Our comprehensive analysis demonstrates that, despite substantial progress that has been made, schema design is still a developing field and considerable challenges need to be addressed, notably for NoSQL databases. We highlight the most important findings from the results of our analysis and identify areas for future research work.
自调整是自主数据库的一项功能,包括自动模式设计问题。它旨在提供优化的模式,从而提高数据库的整体性能。在关系数据库中,自动模式设计侧重于物理模式的自动设计,而在 NoSQL 数据库中,则要考虑所有层次的表示:概念、逻辑和物理。这主要是因为后者大多没有模式,缺乏像 SQL 数据库那样的标准模式设计程序。在这项工作中,我们对 SQL 和 NoSQL 数据库中的自动模式设计进行了系统的文献调查。我们确定了模式设计问题所使用的表示层次和方法,并提出了一种新颖的分类法,用于对不同的模式设计解决方案进行分类和比较。我们的综合分析表明,尽管已经取得了实质性进展,但模式设计仍是一个发展中的领域,需要应对相当大的挑战,特别是对于 NoSQL 数据库。我们强调了分析结果中最重要的发现,并确定了未来研究工作的领域。

Automated medical coding, an essential task for healthcare operation and delivery, makes unstructured data manageable by predicting medical codes from clinical documents. Recent advances in deep learning and natural language processing have been widely applied to this task. However, deep learning-based medical coding lacks a unified view of the design of neural network architectures. This review proposes a unified framework to provide a general understanding of the building blocks of medical coding models and summarizes recent advanced models under the proposed framework. Our unified framework decomposes medical coding into four main components, i.e., encoder modules for text feature extraction, mechanisms for building deep encoder architectures, decoder modules for transforming hidden representations into medical codes, and the usage of auxiliary information. Finally, we introduce the benchmarks and real-world usage and discuss key research challenges and future directions.

自动医疗编码是医疗运营和交付的一项重要任务,它通过预测临床文件中的医疗编码来管理非结构化数据。深度学习和自然语言处理领域的最新进展已被广泛应用于这项任务。然而,基于深度学习的医疗编码缺乏统一的神经网络架构设计观点。本综述提出了一个统一的框架,以提供对医疗编码模型构件的一般理解,并总结了拟议框架下的近期先进模型。我们的统一框架将医学编码分解为四个主要部分,即用于文本特征提取的编码器模块、构建深度编码器架构的机制、将隐藏表征转化为医学代码的解码器模块以及辅助信息的使用。最后,我们介绍了基准和实际使用情况,并讨论了主要研究挑战和未来方向。

The metaverse delivered through converged and amalgamated technologies holds promise. No wonder technology heavyweights, large corporates, research organizations and businesses cutting across industry verticals are racing to put in place a metaverse-first strategy. The bets on consumers rapidly migrating from traditional social networks and collaborative applications to more immersive digital experiences have been placed. However, the transition is not expected to be seamless. Privacy, safety and security concerns abound in the early versions of the metaverse. Increased regulatory oversight and diverse national laws threaten to derail the hype around the metaverse. It is increasingly clear that the final iteration of the metaverse will need to assuage the concerns of individual users while addressing complex legal and regulatory requirements. Thus, a multi-perspective approach needs to be adopted to help set the agenda for the evolution of the metaverse. This research paper examines the different aspects and challenges which the future metaverse will need to address. A set of ”first principles” are formulated, which if implemented will lead to the development of an equitable, inclusive, safe and secure metaverse.
通过融合和合并技术实现的元网络大有可为。难怪技术重量级企业、大型公司、研究机构和跨行业垂直领域的企业都在竞相实施元宇宙优先战略。人们已经把赌注押在消费者从传统的社交网络和协作应用迅速迁移到更身临其境的数字体验上。然而,这一转变预计不会是无缝的。在元宇宙的早期版本中,隐私、安全和安保问题比比皆是。监管的加强和各国法律的多样化有可能会破坏围绕元宇宙的炒作。越来越清楚的是,元宇宙的最终迭代将需要消除个人用户的担忧,同时满足复杂的法律和监管要求。因此,需要采用多角度的方法来帮助制定元海外发展的议程。本研究论文探讨了未来的元网络需要应对的不同方面和挑战。本文提出了一系列 "首要原则",如果这些原则得到实施,将有助于建立一个公平、包容、安全和可靠的元宇宙。

The field of Virtual Reality continues to evolve to provide an ever-greater sense of immersion to the user. However, VR experiences are still primarily constrained through the human senses of vision and audition, with some interest in haptic (mainly vibrotactile) applications. Only recently have olfactory displays- technologies that generate and deliver scent stimuli- been examined to provide the sense of smell to the human olfactory organ in virtual environments. This paper presents a classification and review of olfactory-enhanced virtual reality systems, particularly those that deployed a Head-Mounted Display (HMD) or Cave Automatic Virtual Environment (CAVE) system. In addition, the paper provides a discussion of the various technological and design challenges for developing an olfactory display suitable for enhancing virtual reality experiences. Finally, the paper proposes future perspectives on the field and includes a table summarizing the characteristics and features of the reviewed systems.
虚拟现实领域不断发展,为用户提供越来越强的沉浸感。然而,虚拟现实体验仍然主要受限于人类的视觉和听觉,人们对触觉(主要是振动触觉)应用也有一些兴趣。直到最近,人们才开始研究嗅觉显示器--生成和传递气味刺激的技术--,以便在虚拟环境中为人类嗅觉器官提供嗅觉。本文对嗅觉增强型虚拟现实系统进行了分类和综述,尤其是那些采用头戴式显示器(HMD)或洞穴自动虚拟环境(CAVE)系统的虚拟现实系统。此外,本文还讨论了开发适合增强虚拟现实体验的嗅觉显示器所面临的各种技术和设计挑战。最后,本文提出了该领域的未来展望,并以表格的形式总结了所审查系统的特点和功能。

Recommender systems have become an important instrument to connect people to information. Sparse, complex, and rapidly growing data presents new challenges to traditional recommendation algorithms. To overcome these challenges, various deep learning-based recommendation algorithms have been proposed. Among these, Variational AutoEncoder (VAE)-based recommendation methods stand out. VAEs are based on a flexible probabilistic framework, which is robust for data sparsity and compatible with other deep learning-based models for dealing with multimodal data. In addition, the deep generative structure of VAEs helps to perform Bayesian inference in an efficient manner. VAE-based recommendation algorithms have given rise to many novel graphical models and they have achieved promising performance. In this paper, we conduct a survey to systematically summarize recent VAE-based recommendation algorithms. Four frequently used characteristics of VAE-based recommendation algorithms are summarized, and a taxonomy of VAE-based recommendation algorithms is proposed. We also identify future research directions for, advanced perspectives on, and the application of VAEs in recommendation algorithms, to inspire future work on VAEs for recommender systems.

In the past few years, Differentiable Neural Architecture Search (DNAS) rapidly imposed itself as the trending approach to automate the discovery of deep neural network architectures. This rise is mainly due to the popularity of DARTS (Differentiable ARchitecTure Search), one of the first major DNAS methods. In contrast with previous works based on Reinforcement Learning or Evolutionary Algorithms, DNAS is faster by several orders of magnitude and uses fewer computational resources. In this comprehensive survey, we focused specifically on DNAS and reviewed recent approaches in this field. Furthermore, we proposed a novel challenge-based taxonomy to classify DNAS methods. We also discussed the contributions brought to DNAS in the past few years and its impact on the global NAS field. Finally, we concluded by giving some insights into future research directions for the DNAS field.

在过去几年中,可微分神经架构搜索(DNAS)迅速成为自动发现深度神经网络架构的潮流方法。这种崛起主要归功于 DARTS(可微分神经架构搜索)的流行,它是最早的主要 DNAS 方法之一。与之前基于强化学习或进化算法的工作相比,DNAS 的速度快了几个数量级,而且使用的计算资源更少。在这份综合调查报告中,我们特别关注 DNAS,并回顾了该领域的最新方法。此外,我们还提出了一种新颖的基于挑战的分类法,用于对 DNAS 方法进行分类。我们还讨论了 DNAS 在过去几年中的贡献及其对全球 NAS 领域的影响。最后,我们对 DNAS 领域未来的研究方向提出了一些见解。

Privacy-enhancing technologies are technologies that implement fundamental data protection principles. With respect to biometric recognition, different types of privacy-enhancing technologies have been introduced for protecting stored biometric data which are generally classified as sensitive. In this regard, various taxonomies and conceptual categorizations have been proposed and standardisation activities have been carried out. However, these efforts have mainly been devoted to certain sub-categories of privacy-enhancing technologies and therefore lack generalization. This work provides an overview of concepts of privacy-enhancing technologies for biometric recognition in a unified framework. Key properties and differences between existing concepts are highlighted in detail at each processing step. Fundamental characteristics and limitations of existing technologies are discussed and related to data protection techniques and principles. Moreover, scenarios and methods for the assessment of privacy-enhancing technologies for biometric recognition are presented. This paper is meant as a point of entry to the field of data protection for biometric recognition applications and is directed towards experienced researchers as well as non-experts.

隐私增强技术是实施基本数据保护原则的技术。在生物识别方面,已经引入了不同类型的隐私增强技术来保护存储的生物识别数据,这些数据通常被归类为敏感数据。在这方面,已经提出了各种分类法和概念分类,并开展了标准化活动。不过,这些工作主要针对隐私增强技术的某些子类别,因此缺乏普遍性。这项工作在一个统一的框架内概述了用于生物识别的隐私增强技术的概念。在每个处理步骤中都详细强调了现有概念的关键特性和差异。讨论了现有技术的基本特征和局限性,并将其与数据保护技术和原则联系起来。此外,还介绍了用于生物识别的隐私增强技术的评估方案和方法。本文旨在作为生物识别应用数据保护领域的切入点,面向有经验的研究人员和非专业人员。

Aerial object detection, as object detection in aerial images captured from an overhead perspective, has been widely applied in urban management, industrial inspection, and other aspects. However, the performance of existing aerial object detection algorithms is hindered by variations in object scales and orientations attributed to the aerial perspective. This survey presents a comprehensive review of recent advances in aerial object detection. We start with some basic concepts of aerial object detection and then summarize the five imbalance problems of aerial object detection, including scale imbalance, spatial imbalance, objective imbalance, semantic imbalance, and class imbalance. Moreover, we classify and analyze relevant methods and especially introduce the applications of aerial object detection in practical scenarios.

In the field of Sequential Decision Making (SDM), two paradigms have historically vied for supremacy: Automated Planning (AP) and Reinforcement Learning (RL). In the spirit of reconciliation, this paper reviews AP, RL and hybrid methods (e.g., novel learn to plan techniques) for solving Sequential Decision Processes (SDPs), focusing on their knowledge representation: symbolic, subsymbolic or a combination. Additionally, it also covers methods for learning the SDP structure. Finally, we compare the advantages and drawbacks of the existing methods and conclude that neurosymbolic AI poses a promising approach for SDM, since it combines AP and RL with a hybrid knowledge representation.

在顺序决策(SDM)领域,历来有两种范式争夺主导地位:自动规划(AP)和强化学习(RL)。本着和解的精神,本文回顾了用于解决序列决策过程(SDP)的自动规划、强化学习和混合方法(如新颖的学习规划技术),重点是它们的知识表示:符号表示、次符号表示或组合表示。此外,它还包括学习 SDP 结构的方法。最后,我们比较了现有方法的优缺点,并得出结论:神经符号人工智能是一种很有前途的 SDM 方法,因为它将 AP 和 RL 与混合知识表示法相结合。
