基于随机差分方程（SDE）的挥发性可再生能源（RESS）的随机过程模型共同捕获了连续时间的不断变化的概率分布和时间相关性。它已经使最近的研究能够显着提高动力系统动态不确定性量化和优化的性能。然而，考虑到PV的非同质随机过程性质，仍然存在一个具有挑战性的问题：如何获得用于光伏电源的现实和准确的SDE模型，以反映其在线操作中的天气不确定性，特别是在高分辨率数值时天气预报（NWP）对于许多分布式工厂不可用？为了填补这个差距，本文发现，只有使用来自低分辨率公共天气报告的廉价数据，可以构建精确的PV电源SDE模型。具体地，构建每小时参数化的Jacobi扩散过程以在一天内重新创建PV挥发性的时间模式。它的参数使用极端学习机（ELM）的集合来映射到公共天气报告，以反映不同的天气状况。 SDE模型共同捕捉盘流道和陷阱。基于澳门收集的现实数据的统计检验表明，所提出的方法优于一系列最先进的深度学习的时间系列预测方法。

多跳问题回答（QA）需要对多个文档进行推理，以回答一个复杂的问题并提供可解释的支持证据。但是，提供支持证据不足以证明模型已经执行了所需的推理来达到正确的答案。大多数现有的多跳质量检查方法也无法回答大部分子问题，即使他们的父母问题得到了正确的回答。在本文中，我们为多跳QA提出了基于及时的保护学习（PCL）框架，该框架从多跳QA任务中获取了新知识，同时保留了在单跳QA任务上学习的旧知识，从而减轻了遗忘。具体来说，我们首先在现有的单跳质量检查任务上训练模型，然后冻结该模型，并通过为多跳质量检查任务分配其他子网络来扩展它。此外，为了调整预训练的语言模型以刺激特定多跳问题所需的推理类型，我们学习了新型子网络的软提示，以执行特定于类型的推理。 HOTPOTQA基准测试的实验结果表明，PCL具有多跳质量质量质量检查的竞争力，并且在相应的单跳子问题上保留了良好的性能，这表明PCL通过忘记通过忘记来减轻知识丧失的功效。

近年来，破坏预测取得了迅速的进展，尤其是在机器学习（ML）的方法中。理解为什么预测因子使某个预测与未来Tokamak破坏预测指标的预测准确性一样至关重要。大多数破坏预测因素的目的是准确性或跨机能力。但是，如果可以解释中断预测模型，则可以说明为什么某些样品被归类为中断前体。这使我们能够说出传入的破坏类型，并使我们深入了解破坏机制。本文根据J-TEXT上的物理引导特征提取（IDP-PGFE）设计了一种称为可解释的破坏预测变量的破坏预测变量。通过提取物理引导的特征有效地改善了模型的预测性能。需要高性能模型来确保解释结果的有效性。 IDP-PGFE的可解释性研究提供了对J-Text破坏的理解，并且通常与现有的破坏理解一致。 IDP-PGFE已被应用于破坏，因为在J文本上的密度极限实验的密度不断增加。 PGFE的时间演变具有贡献，表明ECRH的应用触发了辐射引起的破坏，从而降低了破坏时的密度。虽然RMP的应用确实提高了J文本中的密度极限。解释性研究指导了RMP不仅会影响MHD不稳定性，而且还会影响辐射轮廓的密度极限破坏的物理机制，从而延迟了密度极限的破坏。

预测不同托卡马克人的破坏是要克服的巨大障碍。未来的Tokamaks在高性能排放时几乎无法忍受中断。很少有高性能的破坏排放几乎无法构成丰富的训练集，这使得当前数据驱动的方法难以获得可接受的结果。能够将在一个Tokamak训练的中断预测模型转移到另一种训练的机器学习方法以解决该问题。关键是一个包含特征提取器的破坏预测模型，该模型能够在Tokamak诊断数据中提取常见的破坏前体痕迹，并具有可转移的破坏分类器。基于上面的问题，该论文首先提出了专门针对Tokamaks上的普通诊断中的破坏前体特征而设计的深融合功能提取器，该特征是根据当前已知的破坏前体，为可转移模型提供了有希望的基础。通过与J-Text上的手动特征提取进行比较，可以证明融合功能提取器。基于在J-TEXT上训练的功能提取器，将中断预测模型转移到East数据中，仅来自East实验的20次放电。该性能与经过1896年出院的模型相当。从其他模型培训方案之间的比较，转移学习表明了其在预测不同托卡马克人的破坏方面的潜力。

有效的多跳问答（QA）需要在多个分散的段落上进行推理，并提供答案的解释。大多数现有方法无法提供可解释的推理过程，以说明这些模型如何得出答案。在本文中，我们提出了一种基于多跳QA的抽象含义表示形式（QDAMR）的问题分解方法，该方法通过将多跳问题分解为更简单的子问题并按顺序回答它们来实现可解释的推理。由于注释分解很昂贵，因此我们首先将理解多跳问题的复杂性委托给AMR解析器。然后，我们通过基于所需的推理类型对相应的AMR图进行分割实现多跳问题的分解。最后，我们使用AMR到文本生成模型生成子问题，并使用现成的QA模型回答它们。 HOTPOTQA的实验结果表明，我们的方法在可解释的推理方面具有竞争力，并且QDAMR产生的子问题是良好的，表现优于现有的基于问题分解的多跳质量质量检查方法。

The development of social media user stance detection and bot detection methods rely heavily on large-scale and high-quality benchmarks. However, in addition to low annotation quality, existing benchmarks generally have incomplete user relationships, suppressing graph-based account detection research. To address these issues, we propose a Multi-Relational Graph-Based Twitter Account Detection Benchmark (MGTAB), the first standardized graph-based benchmark for account detection. To our knowledge, MGTAB was built based on the largest original data in the field, with over 1.55 million users and 130 million tweets. MGTAB contains 10,199 expert-annotated users and 7 types of relationships, ensuring high-quality annotation and diversified relations. In MGTAB, we extracted the 20 user property features with the greatest information gain and user tweet features as the user features. In addition, we performed a thorough evaluation of MGTAB and other public datasets. Our experiments found that graph-based approaches are generally more effective than feature-based approaches and perform better when introducing multiple relations. By analyzing experiment results, we identify effective approaches for account detection and provide potential future research directions in this field. Our benchmark and standardized evaluation procedures are freely available at: https://github.com/GraphDetec/MGTAB.

Interview has been regarded as one of the most crucial step for recruitment. To fully prepare for the interview with the recruiters, job seekers usually practice with mock interviews between each other. However, such a mock interview with peers is generally far away from the real interview experience: the mock interviewers are not guaranteed to be professional and are not likely to behave like a real interviewer. Due to the rapid growth of online recruitment in recent years, recruiters tend to have online interviews, which makes it possible to collect real interview data from real interviewers. In this paper, we propose a novel application named EZInterviewer, which aims to learn from the online interview data and provides mock interview services to the job seekers. The task is challenging in two ways: (1) the interview data are now available but still of low-resource; (2) to generate meaningful and relevant interview dialogs requires thorough understanding of both resumes and job descriptions. To address the low-resource challenge, EZInterviewer is trained on a very small set of interview dialogs. The key idea is to reduce the number of parameters that rely on interview dialogs by disentangling the knowledge selector and dialog generator so that most parameters can be trained with ungrounded dialogs as well as the resume data that are not low-resource. Evaluation results on a real-world job interview dialog dataset indicate that we achieve promising results to generate mock interviews. With the help of EZInterviewer, we hope to make mock interview practice become easier for job seekers.

Dynamic treatment regimes assign personalized treatments to patients sequentially over time based on their baseline information and time-varying covariates. In mobile health applications, these covariates are typically collected at different frequencies over a long time horizon. In this paper, we propose a deep spectral Q-learning algorithm, which integrates principal component analysis (PCA) with deep Q-learning to handle the mixed frequency data. In theory, we prove that the mean return under the estimated optimal policy converges to that under the optimal one and establish its rate of convergence. The usefulness of our proposal is further illustrated via simulations and an application to a diabetes dataset.

Temporal sentence grounding (TSG) aims to identify the temporal boundary of a specific segment from an untrimmed video by a sentence query. All existing works first utilize a sparse sampling strategy to extract a fixed number of video frames and then conduct multi-modal interactions with query sentence for reasoning. However, we argue that these methods have overlooked two indispensable issues: 1) Boundary-bias: The annotated target segment generally refers to two specific frames as corresponding start and end timestamps. The video downsampling process may lose these two frames and take the adjacent irrelevant frames as new boundaries. 2) Reasoning-bias: Such incorrect new boundary frames also lead to the reasoning bias during frame-query interaction, reducing the generalization ability of model. To alleviate above limitations, in this paper, we propose a novel Siamese Sampling and Reasoning Network (SSRN) for TSG, which introduces a siamese sampling mechanism to generate additional contextual frames to enrich and refine the new boundaries. Specifically, a reasoning strategy is developed to learn the inter-relationship among these frames and generate soft labels on boundaries for more accurate frame-query reasoning. Such mechanism is also able to supplement the absent consecutive visual semantics to the sampled sparse frames for fine-grained activity understanding. Extensive experiments demonstrate the effectiveness of SSRN on three challenging datasets.

Human parsing aims to partition humans in image or video into multiple pixel-level semantic parts. In the last decade, it has gained significantly increased interest in the computer vision community and has been utilized in a broad range of practical applications, from security monitoring, to social media, to visual special effects, just to name a few. Although deep learning-based human parsing solutions have made remarkable achievements, many important concepts, existing challenges, and potential research directions are still confusing. In this survey, we comprehensively review three core sub-tasks: single human parsing, multiple human parsing, and video human parsing, by introducing their respective task settings, background concepts, relevant problems and applications, representative literature, and datasets. We also present quantitative performance comparisons of the reviewed methods on benchmark datasets. Additionally, to promote sustainable development of the community, we put forward a transformer-based human parsing framework, providing a high-performance baseline for follow-up research through universal, concise, and extensible solutions. Finally, we point out a set of under-investigated open issues in this field and suggest new directions for future study. We also provide a regularly updated project page, to continuously track recent developments in this fast-advancing field: https://github.com/soeaver/awesome-human-parsing.
