The rapid development of aspect-based sentiment analysis (ABSA) within recent decades shows great potential for real-world society. The current ABSA works, however, are mostly limited to the scenario of a single text piece, leaving the study in dialogue contexts unexplored. In this work, we introduce a novel task of conversational aspect-based sentiment quadruple analysis, namely DiaASQ, aiming to detect the sentiment quadruple of target-aspect-opinion-sentiment in a dialogue. DiaASQ bridges the gap between fine-grained sentiment analysis and conversational opinion mining. We manually construct a large-scale, high-quality Chinese dataset and also obtain the English version dataset via manual translation. We deliberately propose a neural model to benchmark the task. It advances in effectively performing end-to-end quadruple prediction and manages to incorporate rich dialogue-specific and discourse feature representations for better cross-utterance quadruple extraction. We finally point out several potential future works to facilitate the follow-up research of this new task. The DiaASQ data is open at https://github.com/unikcc/DiaASQ

大量的数据和创新算法使数据驱动的建模成为现代行业的流行技术。在各种数据驱动方法中，潜在变量模型（LVM）及其对应物占主要份额，并在许多工业建模领域中起着至关重要的作用。 LVM通常可以分为基于统计学习的经典LVM和基于神经网络的深层LVM（DLVM）。我们首先讨论经典LVM的定义，理论和应用，该定义和应用既是综合教程，又是对经典LVM的简短申请调查。然后，我们对当前主流DLVM进行了彻底的介绍，重点是其理论和模型体系结构，此后不久就提供了有关DLVM的工业应用的详细调查。上述两种类型的LVM具有明显的优势和缺点。具体而言，经典的LVM具有简洁的原理和良好的解释性，但是它们的模型能力无法解决复杂的任务。基于神经网络的DLVM具有足够的模型能力，可以在复杂的场景中实现令人满意的性能，但它以模型的解释性和效率为例。旨在结合美德并减轻这两种类型的LVM的缺点，并探索非神经网络的举止以建立深层模型，我们提出了一个新颖的概念，称为“轻量级Deep LVM（LDLVM）”。在提出了这个新想法之后，该文章首先阐述了LDLVM的动机和内涵，然后提供了两个新颖的LDLVM，并详尽地描述了其原理，建筑和优点。最后，讨论了前景和机会，包括重要的开放问题和可能的研究方向。

错位检测和诊断（MDD）技术是计算机辅助发音训练系统（CAPT）的关键组成部分。在评估受约束语音的发音质量的领域中，给定的转录可以扮演教师的角色。常规方法已充分利用了模型构建或改善系统性能的先前文本，例如强制对准和扩展识别网络。最近，一些基于端到端的方法试图将先前的文本纳入模型训练中，并初步显示出有效性。但是，先前的研究主要考虑将原始注意力机制与文本表示融合，而无需考虑可能的文本 - 概述不匹配。在本文中，我们提出了一种门控策略，该策略在抑制无关的文本信息的同时，对相关音频功能更为重要。此外，鉴于转录，我们设计了额外的对比损失，以减少音素识别和MDD的学习目标之间的差距。我们使用两个公共可用数据集（Timit和L2-极）进行了实验，而我们的最佳模型将F1分数从57.51美元\％$ $ $ $ $ 61.75 \％\％\％提高。此外，我们提供了详细的分析，以阐明门控机制和对MDD的对比度学习的有效性。

隐性话语关系识别（IDRR）是话语分析中的一个具有挑战性，但重要的任务。大多数现有方法如何培训多个模型以独立预测多级标签，同时忽略分层结构标签之间的依赖。在本文中，我们将多级IDRR视为条件标签序列生成任务，并为其提出标签依赖感知序列生成模型（LDSGM）。具体而言，我们首先设计标签专注编码器，以了解输入实例的全局表示及其级别特定上下文，其中标记依赖性被集成以获取更好的标签嵌入。然后，我们使用标签序列解码器以自上而下方式输出预测标签，其中预测的更高级别标签直接用于指导当前级别的标签预测。我们进一步开发了一个相互学习的增强培训方法，以利用了基础方向上的标签依赖性，该依赖于训练期间引入的辅助解码器捕获。 PDTB数据集上的实验结果表明，我们的模型在多级IDRR上实现了最先进的性能。我们将在https://github.com/nlpersecjtu/ldsgm发布我们的代码。

生成的型号推理需要机器生成描述日常情景的句子，这是几种概念，最近引起了很多关注。然而，现有模型不能表现和人类，因为它们产生的句子通常是难以置疑和语法的不正确。在本文中，灵感来自人类创造句子的过程，我们提出了一种新颖的知识增强的致辞生成框架，被称为kgr ^ 4，由四个阶段组成：检索，回顾，精炼，重新思考。在此框架下，我们首先执行检索以搜索从外部语料库作为原型的相关句子。然后，我们训练发电机编辑或复制这些原型以生成候选句子，其中基于AutoEncoder的炼油器将修复候选句子。最后，我们从具有不同超参数的生成器产生的候选句子中选择输出句子。对蒙古基准测试的实验结果和深入分析强烈展示了我们框架的有效性。特别是，KGR ^ 4获得官方排行榜中的33.56个香料点，优于前面报告的最佳结果2.49香料点，实现最先进的性能。

Simile recognition involves two subtasks: simile sentence classification that discriminates whether a sentence contains simile, and simile component extraction that locates the corresponding objects (i.e., tenors and vehicles). Recent work ignores features other than surface strings. In this paper, we explore expressive features for this task to achieve more effective data utilization. Particularly, we study two types of features: 1) input-side features that include POS tags, dependency trees and word definitions, and 2) decoding features that capture the interdependence among various decoding decisions. We further construct a model named HGSR, which merges the input-side features as a heterogeneous graph and leverages decoding features via distillation. Experiments show that HGSR significantly outperforms the current state-of-the-art systems and carefully designed baselines, verifying the effectiveness of introduced features. Our code is available at https://github.com/DeepLearnXMU/HGSR.

As an efficient way to integrate multiple distributed energy resources and the user side, a microgrid is mainly faced with the problems of small-scale volatility, uncertainty, intermittency and demand-side uncertainty of DERs. The traditional microgrid has a single form and cannot meet the flexible energy dispatch between the complex demand side and the microgrid. In response to this problem, the overall environment of wind power, thermostatically controlled loads, energy storage systems, price-responsive loads and the main grid is proposed. Secondly, the centralized control of the microgrid operation is convenient for the control of the reactive power and voltage of the distributed power supply and the adjustment of the grid frequency. However, there is a problem in that the flexible loads aggregate and generate peaks during the electricity price valley. The existing research takes into account the power constraints of the microgrid and fails to ensure a sufficient supply of electric energy for a single flexible load. This paper considers the response priority of each unit component of TCLs and ESSs on the basis of the overall environment operation of the microgrid so as to ensure the power supply of the flexible load of the microgrid and save the power input cost to the greatest extent. Finally, the simulation optimization of the environment can be expressed as a Markov decision process process. It combines two stages of offline and online operations in the training process. The addition of multiple threads with the lack of historical data learning leads to low learning efficiency. The asynchronous advantage actor-critic with the experience replay pool memory library is added to solve the data correlation and nonstatic distribution problems during training.

属性网络上的节点分类是一项半监督任务，对于网络分析至关重要。通过将图形卷积网络（GCN）中的两个关键操作解耦，即具有转换和邻域聚合，截断的GCN的一些最新作品可以支持这些信息，以更深入地传播并实现高级性能。但是，它们遵循GCN的传统结构感知的传播策略，因此很难捕获节点的属性相关性，并对由两个端点属于不同类别的边缘描述的结构噪声敏感。为了解决这些问题，我们提出了一种新方法，称为“裂开式”传播，然后训练（PAMT）。关键思想是将属性相似性掩码整合到结构感知的传播过程中。这样，PAMT可以在传播过程中保留相邻节点的属性相关性，并有效地减少结构噪声的影响。此外，我们开发了一种迭代改进机制，以在改善培训性能的培训过程中更新相似性面罩。在四个现实世界数据集上进行的广泛实验证明了PAMT的出色性能和鲁棒性。

近年来，图形变压器在各种图形学习任务上表现出了优势。但是，现有图形变压器的复杂性与节点的数量二次缩放，因此难以扩展到具有数千个节点的图形。为此，我们提出了一个邻域聚集图变压器（Nagphormer），该变压器可扩展到具有数百万节点的大图。在将节点特征馈送到变压器模型中之前，Nagphormer构造令牌由称为Hop2Token的邻域聚合模块为每个节点。对于每个节点，Hop2token聚合从每个跳跃到表示形式的邻域特征，从而产生一系列令牌向量。随后，不同HOP信息的结果序列是变压器模型的输入。通过将每个节点视为一个序列，可以以迷你批量的方式训练Nagphormer，从而可以扩展到大图。 Nagphormer进一步开发了基于注意力的读数功能，以便学习每个跳跃的重要性。我们在各种流行的基准测试中进行了广泛的实验，包括六个小数据集和三个大数据集。结果表明，Nagphormer始终优于现有的图形变压器和主流图神经网络。

Recent advances in domain adaptation show that deep self-training presents a powerful means for unsupervised domain adaptation. These methods often involve an iterative process of predicting on target domain and then taking the confident predictions as pseudo-labels for retraining. However, since pseudo-labels can be noisy, self-training can put overconfident label belief on wrong classes, leading to deviated solutions with propagated errors. To address the problem, we propose a confidence regularized self-training (CRST) framework, formulated as regularized self-training. Our method treats pseudo-labels as continuous latent variables jointly optimized via alternating optimization. We propose two types of confidence regularization: label regularization (LR) and model regularization (MR). CRST-LR generates soft pseudo-labels while CRST-MR encourages the smoothness on network output. Extensive experiments on image classification and semantic segmentation show that CRSTs outperform their non-regularized counterpart with state-of-the-art performance.
