In this paper, we study the problem of knowledge-intensive text-to-SQL, in which domain knowledge is necessary to parse expert questions into SQL queries over domain-specific tables. We formalize this scenario by building a new Chinese benchmark KnowSQL consisting of domain-specific questions covering various domains. We then address this problem by presenting formulaic knowledge, rather than by annotating additional data examples. More concretely, we construct a formulaic knowledge bank as a domain knowledge base and propose a framework (ReGrouP) to leverage this formulaic knowledge during parsing. Experiments using ReGrouP demonstrate a significant 28.2% improvement overall on KnowSQL.

电线杆和建筑物边缘经常是城市道路上可观察到的对象,为各种计算机视觉任务提供了可靠的提示。为了重复提取它们作为特征并在离散激光镜头框架之间进行注册,我们提出了第一个基于学习的功能分割和LIDAR点云中3D线的描述模型。为了训练我们的模型,而无需耗时和乏味的数据标记过程,我们首先生成了目标线基本外观的合成原始图,并构建一个迭代线自动标记的过程,以逐步完善真实激光扫描的线路标签。我们的分割模型可以在任意规模的扰动下提取线,我们使用共享的EDGECONV编码层共同训练两个分割和描述符头。基于模型,我们可以在没有初始转换提示的情况下构建一个高度可用的全局注册模块,用于点云注册。实验表明,我们基于线的注册方法对基于最先进的方法的方法具有很高的竞争力。我们的代码可在https://github.com/zxrzju/superline3d.git上找到。

在本文中,我们调查了正规化的力量,即在解决广泛形式的游戏(EFGS)方面的加强学习和优化方面的常见技术。我们提出了一系列新算法,基于正规化游戏的回报功能,并建立一组收敛结果,这些结果严格改善了现有的假设或更强的收敛保证。特别是,我们首先证明了膨胀的乐观镜下降(DOMD),一种用于求解EFG的有效变体,具有自适应正则化可以实现快速的$ \ tilde o(1/t)$ last-Ilt-Ilt-Ilt-It-last-Ilt-It-titer-In-titer-Inter-In-Elt-It-Triperate Connergengengenge没有纳什平衡(NE)的独特性假设。此外,正规化的膨胀倍增权重更新(reg-domwu)是reg-domd的实例,进一步享受了$ \ tilde o(1/t)$ ther-tir-tir-tir-tir-tir-tir-ter-tir-tir-ter-tir-tir-tir-tir-tir-tir-tir-tir-tir-ter-ter-ter-ter-ter-ter-ter-ter-ter-tir-ter-ter-tir-trientate Convergence。这解决了一个关于OMWU算法是否可以在没有EFG和正常形式游戏文献中的唯一假设的情况下获得的迭代融合的一个悬而未决的问题。其次,我们表明,正式化的反事实遗憾最小化(reg-cfr),具有乐观的镜像下降算法的变体作为遗憾少量器,可以实现$ o(1/t^{1/4})$ best-Ilterate和$ $ o(1/t^{3/4})$用于在EFG中查找NE的平均值收敛率。最后,我们表明Reg-CFR可以实现渐近的最后一介质收敛,而最佳$ O(1/t)$平均识别收敛速率可用于查找扰动的EFGS的NE,这对于找到近似广泛形式的完美非常有用平衡(EFPE)。据我们所知,它们构成了CFR型算法的第一个最后近期收敛结果,同时匹配SOTA平均识别收敛速率在寻找非扰动的EFG中的NE中。我们还提供数值结果来证实我们算法的优势。

现有的置换不变方法可以根据聚合范围(即全球聚合和局部局部)分为两类。尽管全局聚合方法,e。 g。,PointNet和Deep Sets,参与更简单的结构,它们的性能比PointNet ++和Point Transformer等局部聚合较差。如果存在具有简单结构,竞争性能甚至更少参数的全球聚合方法,那么它仍然是一个空旷的问题。在本文中,我们提出了一个基于双MLP点产品的新型全局聚合置换不变的网络,称为DUMLP-PIN,该网络能够用于提取集合输入的功能,包括无序或非结构的像素,属性,atter和Point和Point和Point云数据集。我们严格地证明,DUMLP-PIN实现的任何置换不变函数都可以通过点产生方式分解为两个或多个置换量的函数,因为给定输入集的基数大于阈值。我们还表明,在某些条件下,可以将DUMLP针视为具有强大限制的深度集。 DUMLP-PIN的性能在具有不同数据集的几个不同任务上进行了评估。实验结果表明,我们的DUMLP-PIN在像素集和属性集的两个分类问题上取得了最佳结果。在点云分类和零件分割上,DUMLP-PIN的准确性非常接近SO-FAR最佳表现最佳的本地聚合方法,仅差异1-2%,而所需参数的数量显着降低了分类分别超过85%和69%的分割。该代码可在https://github.com/jaronthu/dumlp-pin上公开获得。

知识图(KGS)代表作为三元组的事实已被广泛采用在许多应用中。 LIGHT预测和规则感应等推理任务对于KG的开发很重要。已经提出了知识图形嵌入式(KGES)将kg的实体和kg与持续向量空间的关系进行了建议,以获得这些推理任务,并被证明是有效和强大的。但在实际应用中申请和部署KGE的合理性和可行性尚未探索。在本文中,我们讨论并报告我们在真实域应用程序中部署KGE的经验:电子商务。我们首先为电子商务KG系统提供三个重要的探索者:1)注意推理,推理几个目标关系更为关注而不是全部; 2)解释,提供预测的解释,帮助用户和业务运营商理解为什么预测; 3)可转让规则,生成可重用的规则,以加速将千克部署到新系统。虽然非现有KGE可以满足所有这些DesiderATA,但我们提出了一种新颖的一种,可说明的知识图表注意网络,通过建模三元组之间的相关性而不是纯粹依赖于其头实体,关系和尾部实体嵌入来预测。它可以自动选择预测的注意力三倍,并同时记录它们的贡献,从该解释可以很容易地提供,可以有效地生产可转移规则。我们经验表明,我们的方法能够在我们的电子商务应用程序中满足所有三个DesiderATA,并从实际域应用程序中倾斜于数据集的典型基线。

机器学习模型在高赌注应用中变得普遍存在。尽管在绩效方面有明显的效益,但该模型可以表现出对少数民族群体的偏见,并导致决策过程中的公平问题,导致对个人和社会的严重负面影响。近年来,已经开发了各种技术来减轻机器学习模型的偏差。其中,加工方法已经增加了社区的关注,在模型设计期间直接考虑公平,以诱导本质上公平的模型,从根本上减轻了产出和陈述中的公平问题。在本调查中,我们审查了加工偏置减缓技术的当前进展。基于在模型中实现公平的地方,我们将它们分类为明确和隐性的方法,前者直接在培训目标中纳入公平度量,后者重点介绍精炼潜在代表学习。最后,我们在讨论该社区中的研究挑战来讨论调查,以激励未来的探索。

Knowledge graph embedding (KGE), which maps entities and relations in a knowledge graph into continuous vector spaces, has achieved great success in predicting missing links in knowledge graphs. However, knowledge graphs often contain incomplete triples that are difficult to inductively infer by KGEs. To address this challenge, we resort to analogical inference and propose a novel and general self-supervised framework AnKGE to enhance KGE models with analogical inference capability. We propose an analogical object retriever that retrieves appropriate analogical objects from entity-level, relation-level, and triple-level. And in AnKGE, we train an analogy function for each level of analogical inference with the original element embedding from a well-trained KGE model as input, which outputs the analogical object embedding. In order to combine inductive inference capability from the original KGE model and analogical inference capability enhanced by AnKGE, we interpolate the analogy score with the base model score and introduce the adaptive weights in the score function for prediction. Through extensive experiments on FB15k-237 and WN18RR datasets, we show that AnKGE achieves competitive results on link prediction task and well performs analogical inference.

Text-to-SQL semantic parsing is an important NLP task, which greatly facilitates the interaction between users and the database and becomes the key component in many human-computer interaction systems. Much recent progress in text-to-SQL has been driven by large-scale datasets, but most of them are centered on English. In this work, we present MultiSpider, the largest multilingual text-to-SQL dataset which covers seven languages (English, German, French, Spanish, Japanese, Chinese, and Vietnamese). Upon MultiSpider, we further identify the lexical and structural challenges of text-to-SQL (caused by specific language properties and dialect sayings) and their intensity across different languages. Experimental results under three typical settings (zero-shot, monolingual and multilingual) reveal a 6.1% absolute drop in accuracy in non-English languages. Qualitative and quantitative analyses are conducted to understand the reason for the performance drop of each language. Besides the dataset, we also propose a simple schema augmentation framework SAVe (Schema-Augmentation-with-Verification), which significantly boosts the overall performance by about 1.8% and closes the 29.5% performance gap across languages.

In this paper, we present a pure-Python open-source library, called PyPop7, for black-box optimization (BBO). It provides a unified and modular interface for more than 60 versions and variants of different black-box optimization algorithms, particularly population-based optimizers, which can be classified into 12 popular families: Evolution Strategies (ES), Natural Evolution Strategies (NES), Estimation of Distribution Algorithms (EDA), Cross-Entropy Method (CEM), Differential Evolution (DE), Particle Swarm Optimizer (PSO), Cooperative Coevolution (CC), Simulated Annealing (SA), Genetic Algorithms (GA), Evolutionary Programming (EP), Pattern Search (PS), and Random Search (RS). It also provides many examples, interesting tutorials, and full-fledged API documentations. Through this new library, we expect to provide a well-designed platform for benchmarking of optimizers and promote their real-world applications, especially for large-scale BBO. Its source code and documentations are available at https://github.com/Evolutionary-Intelligence/pypop and https://pypop.readthedocs.io/en/latest, respectively.

Achieving multiple genres and long-term choreography sequences from given music is a challenging task, due to the lack of a multi-genre dataset. To tackle this problem,we propose a Multi Art Genre Intelligent Choreography Dataset (MagicDance). The data of MagicDance is captured from professional dancers assisted by motion capture technicians. It has a total of 8 hours 3D motioncapture human dances with paired music, and 16 different dance genres. To the best of our knowledge, MagicDance is the 3D dance dataset with the most genres. In addition, we find that the existing two types of methods (generation-based method and synthesis-based method) can only satisfy one of the diversity and duration, but they can complement to some extent. Based on this observation, we also propose a generation-synthesis choreography network (MagicNet), which cascades a Diffusion-based 3D Diverse Dance fragments Generation Network (3DGNet) and a Genre&Coherent aware Retrieval Module (GCRM). The former can generate various dance fragments from only one music clip. The latter is utilized to select the best dance fragment generated by 3DGNet and switch them into a complete dance according to the genre and coherent matching score. Quantitative and qualitative experiments demonstrate the quality of MagicDance, and the state-of-the-art performance of MagicNet.
