尽管在许多应用中取得了巨大的成功，但深度神经网络在实践中并不总是强大的。例如，用于分类任务的卷积神经元网络（CNN）模型通常在对某些特定类别的对象分类时表现不佳。在这项工作中，我们关注的是修补CNN模型的弱部分，而不是通过整个模型的昂贵重新培训来改进它。受到软件工程中模块化和组成的基本概念的启发，我们提出了一种压缩模块化方法CNNSplitter，该方法将$ N $ class分类的强CNN模型分解为$ n $ n $ n $ n $ smill CNN模块。每个模块都是一个子模型，其中包含强模型的卷积内核的一部分。为了修补对目标类（TC）进行不满意的弱CNN模型，我们将弱的CNN模型与从强CNN模型获得的相应模块组成。因此，弱CNN模型识别TC的能力可以通过修补来提高。此外，识别非TCS的能力也得到了提高，因为将样品错误分类为TC可以正确分类为非TCS。在三个广泛使用的数据集上使用两个代表性CNN的实验结果表明，在精度和召回方面，TC的平均改进分别为12.54％和2.14％。此外，修补程序将非TCS的准确性提高了1.18％。结果表明，CNNSplitter可以通过模块化和组成来修补弱的CNN模型，从而为开发可靠的CNN模型提供了新的解决方案。

预训练模型已在许多代码智能任务中有效。这些模型在大规模未标记的语料库中进行了预训练，然后在下游任务中进行了微调。但是，由于预训练和下游任务的输入是不同的形式，因此很难充分探索预训练模型的知识。此外，微调的性能强烈依赖于下游数据的量，而实际上，具有稀缺数据的场景很常见。自然语言处理（NLP）领域的最新研究表明，迅速调整，一种调整的新范式，减轻上述问题并在各种NLP任务中实现了有希望的结果。在迅速调整中，在调整过程中插入的提示提供了特定于任务的知识，这对于具有相对较少数据的任务特别有益。在本文中，我们凭经验评估了代码智能任务中迅速调整的用法和效果。我们对流行的预训练模型Codebert和codet5进行及时调整，并尝试三个代码智能任务，包括缺陷预测，代码摘要和代码翻译。我们的实验结果表明，在所有三个任务中，迅速调整始终优于微调。此外，及时调整在低资源场景中显示出很大的潜力，例如，对于代码摘要，平均将微调的BLEU分数提高了26％以上。我们的结果表明，我们可以调整代码智能任务的迅速调整，以实现更好的性能，尤其是在缺乏特定于任务的数据时，我们可以调整及时调整。

随着电子商务行业的繁荣，将各种方式（例如愿景和语言）用于描述产品项目。了解这种多样化的数据是一个巨大的挑战，尤其是通过有用的图像区域提取文本序列中的属性值对。尽管以前的一系列作品已致力于这项任务，但很少有人研究障碍，阻碍了进一步的进一步改进：1）上流单模式预处理的参数不足，而无需在下游多人中进行适当的合理微调。 - 模式任务。 2）要选择图像的描述性部分，不管先验的信息应通过更强的编码器将与语言相关的信息编码为常见的语言嵌入空间，从而广泛应用了简单的晚期融合。 3）由于产品之间的多样性，它们的属性集往往差异很大，但是当前的方法以不必要的最大范围预测，并带来更多潜在的假阳性。为了解决这些问题，我们在本文中提出了一种新颖的方法，可以通过统一学习方案和动态范围最小化提高多模式电子商务属性的价值提取：1）首先，统一方案旨在共同培训多模式任务带有预审计的单模式参数。 2）其次，提出了一种文本引导的信息范围最小化方法，以将每种模态的描述性部分自适应地编码为具有强大审慎的语言模型的相同空间。 3）此外，提出了一种原型引导的属性范围最小化方法，以首先确定当前产品的适当属性集，然后选择原型以指导所选属性的预测。关于流行的多模式电子商务基准的实验表明，我们的方法比其他最新技术的方法更出色。

轨迹预测和行为决策是自动驾驶汽车的两项重要任务，他们需要对环境环境有良好的了解；通过参考轨迹预测的输出，可以更好地做出行为决策。但是，大多数当前解决方案分别执行这两个任务。因此，提出了结合多个线索的联合神经网络，并将其命名为整体变压器，以预测轨迹并同时做出行为决策。为了更好地探索线索之间的内在关系，网络使用现有知识并采用三种注意力机制：稀疏的多头类型用于减少噪声影响，特征选择稀疏类型，可最佳地使用部分先验知识，并与Sigmoid多头激活类型，用于最佳使用后验知识。与其他轨迹预测模型相比，所提出的模型具有更好的综合性能和良好的解释性。感知噪声稳健性实验表明，所提出的模型具有良好的噪声稳健性。因此，结合多个提示的同时轨迹预测和行为决策可以降低计算成本并增强场景与代理之间的语义关系。

在本文中，我们提出了一种添加在生成的对抗网络（GaN）中不可替代的约束的方法（GaN）的任意大小原始拜耳图像生成。理论上，通过使用GaN培训中的转换数据来说，它能够改善原始数据分布的学习，由于在可逆性和可微分的变换下的两个分布之间的Jensen-Shannon（JS）发散。受益于所提出的方法，可以通过将变换配置为Demosaicing来生成原始拜耳图案图像。结果表明，通过添加另一个变换，所提出的方法能够合成具有任意尺寸的高质量未加工拜耳图像。实验结果表明，所提出的方法生成的图像优于FR \'Echet Inception距离（FID）得分中的现有方法，峰值信号到噪声比（PSNR），以及平均结构相似度（MSSIM），训练过程更多稳定的。为了提出作者的最佳知识，未加工拜耳域中没有开源，大型图像数据集，这对于研究工程至关重要，旨在探索计算机视觉任务的图像信号处理（ISP）管道设计。将现有的常用彩色图像数据集转换为相应的博客版本，所提出的方法可以是对原始图像数据集问题的有希望的解决方案。我们还在实验中显示，通过使用合成的原始拜耳图像训练对象检测框架，可以以端到端的方式（从原始图像到视觉任务）使用，具有可忽略的性能下降。

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.

Weakly-supervised object localization aims to indicate the category as well as the scope of an object in an image given only the image-level labels. Most of the existing works are based on Class Activation Mapping (CAM) and endeavor to enlarge the discriminative area inside the activation map to perceive the whole object, yet ignore the co-occurrence confounder of the object and context (e.g., fish and water), which makes the model inspection hard to distinguish object boundaries. Besides, the use of CAM also brings a dilemma problem that the classification and localization always suffer from a performance gap and can not reach their highest accuracy simultaneously. In this paper, we propose a casual knowledge distillation method, dubbed KD-CI-CAM, to address these two under-explored issues in one go. More specifically, we tackle the co-occurrence context confounder problem via causal intervention (CI), which explores the causalities among image features, contexts, and categories to eliminate the biased object-context entanglement in the class activation maps. Based on the de-biased object feature, we additionally propose a multi-teacher causal distillation framework to balance the absorption of classification knowledge and localization knowledge during model training. Extensive experiments on several benchmarks demonstrate the effectiveness of KD-CI-CAM in learning clear object boundaries from confounding contexts and addressing the dilemma problem between classification and localization performance.

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.

Nowadays, time-stamped web documents related to a general news query floods spread throughout the Internet, and timeline summarization targets concisely summarizing the evolution trajectory of events along the timeline. Unlike traditional document summarization, timeline summarization needs to model the time series information of the input events and summarize important events in chronological order. To tackle this challenge, in this paper, we propose a Unified Timeline Summarizer (UTS) that can generate abstractive and extractive timeline summaries in time order. Concretely, in the encoder part, we propose a graph-based event encoder that relates multiple events according to their content dependency and learns a global representation of each event. In the decoder part, to ensure the chronological order of the abstractive summary, we propose to extract the feature of event-level attention in its generation process with sequential information remained and use it to simulate the evolutionary attention of the ground truth summary. The event-level attention can also be used to assist in extracting summary, where the extracted summary also comes in time sequence. We augment the previous Chinese large-scale timeline summarization dataset and collect a new English timeline dataset. Extensive experiments conducted on these datasets and on the out-of-domain Timeline 17 dataset show that UTS achieves state-of-the-art performance in terms of both automatic and human evaluations.

Hybrid unmanned aerial vehicles (UAVs) integrate the efficient forward flight of fixed-wing and vertical takeoff and landing (VTOL) capabilities of multicopter UAVs. This paper presents the modeling, control and simulation of a new type of hybrid micro-small UAVs, coined as lifting-wing quadcopters. The airframe orientation of the lifting wing needs to tilt a specific angle often within $ 45$ degrees, neither nearly $ 90$ nor approximately $ 0$ degrees. Compared with some convertiplane and tail-sitter UAVs, the lifting-wing quadcopter has a highly reliable structure, robust wind resistance, low cruise speed and reliable transition flight, making it potential to work fully-autonomous outdoor or some confined airspace indoor. In the modeling part, forces and moments generated by both lifting wing and rotors are considered. Based on the established model, a unified controller for the full flight phase is designed. The controller has the capability of uniformly treating the hovering and forward flight, and enables a continuous transition between two modes, depending on the velocity command. What is more, by taking rotor thrust and aerodynamic force under consideration simultaneously, a control allocation based on optimization is utilized to realize cooperative control for energy saving. Finally, comprehensive Hardware-In-the-Loop (HIL) simulations are performed to verify the advantages of the designed aircraft and the proposed controller.
