The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is the world's largest single-dish radio telescope. Its large reflecting surface achieves unprecedented sensitivity but is prone to damage, such as dents and holes, caused by naturally-occurring falling objects. Hence, the timely and accurate detection of surface defects is crucial for FAST's stable operation. Conventional manual inspection involves human inspectors climbing up and examining the large surface visually, a time-consuming and potentially unreliable process. To accelerate the inspection process and increase its accuracy, this work makes the first step towards automating the inspection of FAST by integrating deep-learning techniques with drone technology. First, a drone flies over the surface along a predetermined route. Since surface defects significantly vary in scale and show high inter-class similarity, directly applying existing deep detectors to detect defects on the drone imagery is highly prone to missing and misidentifying defects. As a remedy, we introduce cross-fusion, a dedicated plug-in operation for deep detectors that enables the adaptive fusion of multi-level features in a point-wise selective fashion, depending on local defect patterns. Consequently, strong semantics and fine-grained details are dynamically fused at different positions to support the accurate detection of defects of various scales and types. Our AI-powered drone-based automated inspection is time-efficient, reliable, and has good accessibility, which guarantees the long-term and stable operation of FAST.

关于多模式情感分析的现有研究在很大程度上依赖文本方式，不可避免地会引起文本单词和情感标签之间的虚假相关性。这极大地阻碍了模型的概括能力。为了解决这个问题，我们定义了分发（OOD）多模式分析的任务。该任务旨在估计和减轻文本方式对强大概括的不良影响。为此，我们接受了因果推断，该因果通过因果图检查了因果关系。从图中，我们发现虚假相关性归因于文本模式对模型预测的直接影响，而间接相关性通过考虑多模式语义来更可靠。受此启发的启发，我们设计了一个模型不足的反事实框架，用于多模式情感分析，该框架通过额外的文本模型捕获文本模式的直接效果，并通过多模型估算间接模型。在推断期间，我们首先通过反事实推断估算直接效应，然后从所有模式的总效应中减去它以获得可靠预测的间接效应。广泛的实验显示了我们提出的框架的卓越有效性和概括能力。

多模式面向任务的对话框系统的文本响应生成旨在在给定多模式上下文的情况下生成适当的文本响应，这是一项必不可少但具有挑战性的任务。尽管现有的努力取得了令人信服的成功，但他们仍然遭受了两个关键的局限性：1）忽略生成预训练的好处，以及2）忽略与文本上下文相关的知识。为了解决这些局限性，我们为多模式的以任务为导向的对话框系统（DKMD）提出了一种新颖的双重知识增强的生成预验证的语言模型，由三个关键组成部分组成：双重知识选择，双重知识增强上下文上下文学习和知识增强的响应响应一代。具体来说，双重知识选择组件旨在根据给定上下文的文本和视觉方式选择相关的知识。此后，双重知识增强的上下文学习组件是从全球和局部观点上都无缝地将所选知识整合到多模式上下文的学习中，并探索了跨模式的语义关系。此外，知识增强的响应生成部分包括经过修订的Bart解码器，其中引入了其他点产品知识折线，以明确利用知识来推进文本响应生成。公共数据集的广泛实验验证了拟议的DKMD优于最先进的竞争对手。

视觉问题的视觉关注在视觉问题上应答（VQA）目标在定位有关答案预测的右图像区域，提供强大的技术来促进多模态理解。然而，最近的研究指出，来自视觉关注的突出显示的图像区域通常与给定的问题和答案无关，导致模型混淆正确的视觉推理。为了解决这个问题，现有方法主要是为了对准人类关注的视觉注意力。尽管如此，收集这种人类数据是费力且昂贵的，使其在数据集中调整良好开发的模型。为了解决这个问题，在本文中，我们设计了一种新的视觉关注正规化方法，即attreg，以便在VQA中更好地视觉接地。具体而言，attraT首先识别了由骨干模型出乎意料地忽略（即，分配低注意重量）的问题所必需的图像区域。然后，利用掩模引导的学习方案来规范视觉注意力，以便更多地关注这些忽略的关键区域。所提出的方法是非常灵活的，模型不可知，可以集成到基于大多数基于视觉关注的VQA模型中，并且不需要人类注意监督。已经进行了三个基准数据集，即VQA-CP V2，VQA-CP V1和VQA V2的广泛实验，以评估attreg的有效性。作为副产品，将Attreg纳入强基线LMH时，我们的方法可以实现新的最先进的准确性为60.00％，在VQA-CP V2基准数据集上绝对性能增益为7.01％。 。

In recent years, the exponential proliferation of smart devices with their intelligent applications poses severe challenges on conventional cellular networks. Such challenges can be potentially overcome by integrating communication, computing, caching, and control (i4C) technologies. In this survey, we first give a snapshot of different aspects of the i4C, comprising background, motivation, leading technological enablers, potential applications, and use cases. Next, we describe different models of communication, computing, caching, and control (4C) to lay the foundation of the integration approach. We review current state-of-the-art research efforts related to the i4C, focusing on recent trends of both conventional and artificial intelligence (AI)-based integration approaches. We also highlight the need for intelligence in resources integration. Then, we discuss integration of sensing and communication (ISAC) and classify the integration approaches into various classes. Finally, we propose open challenges and present future research directions for beyond 5G networks, such as 6G.

Currently, most deep learning methods cannot solve the problem of scarcity of industrial product defect samples and significant differences in characteristics. This paper proposes an unsupervised defect detection algorithm based on a reconstruction network, which is realized using only a large number of easily obtained defect-free sample data. The network includes two parts: image reconstruction and surface defect area detection. The reconstruction network is designed through a fully convolutional autoencoder with a lightweight structure. Only a small number of normal samples are used for training so that the reconstruction network can be A defect-free reconstructed image is generated. A function combining structural loss and $\mathit{L}1$ loss is proposed as the loss function of the reconstruction network to solve the problem of poor detection of irregular texture surface defects. Further, the residual of the reconstructed image and the image to be tested is used as the possible region of the defect, and conventional image operations can realize the location of the fault. The unsupervised defect detection algorithm of the proposed reconstruction network is used on multiple defect image sample sets. Compared with other similar algorithms, the results show that the unsupervised defect detection algorithm of the reconstructed network has strong robustness and accuracy.

We study the problem of semantic segmentation calibration. For image classification, lots of existing solutions are proposed to alleviate model miscalibration of confidence. However, to date, confidence calibration research on semantic segmentation is still limited. We provide a systematic study on the calibration of semantic segmentation models and propose a simple yet effective approach. First, we find that model capacity, crop size, multi-scale testing, and prediction correctness have impact on calibration. Among them, prediction correctness, especially misprediction, is more important to miscalibration due to over-confidence. Next, we propose a simple, unifying, and effective approach, namely selective scaling, by separating correct/incorrect prediction for scaling and more focusing on misprediction logit smoothing. Then, we study popular existing calibration methods and compare them with selective scaling on semantic segmentation calibration. We conduct extensive experiments with a variety of benchmarks on both in-domain and domain-shift calibration, and show that selective scaling consistently outperforms other methods.

The booming development and huge market of micro-videos bring new e-commerce channels for merchants. Currently, more micro-video publishers prefer to embed relevant ads into their micro-videos, which not only provides them with business income but helps the audiences to discover their interesting products. However, due to the micro-video recording by unprofessional equipment, involving various topics and including multiple modalities, it is challenging to locate the products related to micro-videos efficiently, appropriately, and accurately. We formulate the microvideo-product retrieval task, which is the first attempt to explore the retrieval between the multi-modal and multi-modal instances. A novel approach named Multi-Queue Momentum Contrast (MQMC) network is proposed for bidirectional retrieval, consisting of the uni-modal feature and multi-modal instance representation learning. Moreover, a discriminative selection strategy with a multi-queue is used to distinguish the importance of different negatives based on their categories. We collect two large-scale microvideo-product datasets (MVS and MVS-large) for evaluation and manually construct the hierarchical category ontology, which covers sundry products in daily life. Extensive experiments show that MQMC outperforms the state-of-the-art baselines. Our replication package (including code, dataset, etc.) is publicly available at https://github.com/duyali2000/MQMC.

Due to the lack of depth information of images and poor detection accuracy in monocular 3D object detection, we proposed the instance depth for multi-scale monocular 3D object detection method. Firstly, to enhance the model's processing ability for different scale targets, a multi-scale perception module based on dilated convolution is designed, and the depth features containing multi-scale information are re-refined from both spatial and channel directions considering the inconsistency between feature maps of different scales. Firstly, we designed a multi-scale perception module based on dilated convolution to enhance the model's processing ability for different scale targets. The depth features containing multi-scale information are re-refined from spatial and channel directions considering the inconsistency between feature maps of different scales. Secondly, so as to make the model obtain better 3D perception, this paper proposed to use the instance depth information as an auxiliary learning task to enhance the spatial depth feature of the 3D target and use the sparse instance depth to supervise the auxiliary task. Finally, by verifying the proposed algorithm on the KITTI test set and evaluation set, the experimental results show that compared with the baseline method, the proposed method improves by 5.27\% in AP40 in the car category, effectively improving the detection performance of the monocular 3D object detection algorithm.

Aiming at the problem that the current video anomaly detection cannot fully use the temporal information and ignore the diversity of normal behavior, an anomaly detection method is proposed to integrate the spatiotemporal information of pedestrians. Based on the convolutional autoencoder, the input frame is compressed and restored through the encoder and decoder. Anomaly detection is realized according to the difference between the output frame and the true value. In order to strengthen the characteristic information connection between continuous video frames, the residual temporal shift module and the residual channel attention module are introduced to improve the modeling ability of the network on temporal information and channel information, respectively. Due to the excessive generalization of convolutional neural networks, in the memory enhancement modules, the hopping connections of each codec layer are added to limit autoencoders' ability to represent abnormal frames too vigorously and improve the anomaly detection accuracy of the network. In addition, the objective function is modified by a feature discretization loss, which effectively distinguishes different normal behavior patterns. The experimental results on the CUHK Avenue and ShanghaiTech datasets show that the proposed method is superior to the current mainstream video anomaly detection methods while meeting the real-time requirements.
