气候变化增加了损害电力系统可靠性并导致多次设备故障的极端天气事件（风暴，大雨，野火）的数量。实时和准确检测潜在线路故障是减轻极端天气影响并激活紧急控制的第一步。功率平衡方程非线性，极端事件中的发电不确定性增加，缺乏电网可观察性会损害传统数据驱动的失败检测方法的效率。同时，基于神经网络的现代化的机器学习方法需要大量数据来检测事故，尤其是在改变时间的环境中。本文提出了一个具有物理信息的线路故障检测器（字段），该探测器利用网格拓扑信息来减少样本和时间复杂性并提高定位准确性。最后，我们说明了与最先进的方法相比，与各种测试用例相比，我们的方法的优越性实证性能。

在这项工作中，使用有限或相对较少数量的脑电图（EEG）信号提出了一个有效的注意力模块，用于情绪分类。该模块被称为单调性限制的注意模块（MCAM），因为它在将特征的革兰氏矩阵转换为注意矩阵以获得更好的特征细化时，可以将先验纳入单调性上。我们的实验表明，MCAM的有效性可与最新的注意模块相媲美，这在提高骨干网络的预测性能时，同时需要更少的参数。还对受过训练的模型的有关不同攻击的预测进行了几项伴随的敏感性分析。这些攻击包括各种频域过滤水平和与多个标签相关的样品之间逐渐变形。我们的结果可以帮助更好地理解预测中不同模块的行为，并可以在数据有限且存在噪音的应用程序中提供指导。

我们考虑随机对照试验的差异问题，通过使用与结果相关的协变量但与治疗无关。我们提出了一种机器学习回归调整的处理效果估算器，我们称之为Mlrate。 Mlrate使用机器学习预测结果来降低估计方差。它采用交叉配件来避免过度偏置，在一般条件下，我们证明了一致性和渐近正常性。 Mlrate对机器学习的预测较差的鲁棒步骤：如果预测与结果不相关，则估计器执行渐近的差异，而不是标准差异估计器，而如果预测与结果高度相关，则效率提升大。在A / A测试中，对于在Facebook实验中通常监测的一组48个结果指标，估计器的差异比简单差分估计器差异超过70％，比仅调整的共同单变量过程约19％用于结果的预测值。

As an important variant of entity alignment (EA), multi-modal entity alignment (MMEA) aims to discover identical entities across different knowledge graphs (KGs) with multiple modalities like images. However, current MMEA algorithms all adopt KG-level modality fusion strategies but ignore modality differences among individual entities, hurting the robustness to potential noise involved in modalities (e.g., unidentifiable images and relations). In this paper we present MEAformer, a multi-modal entity alignment transformer approach for meta modality hybrid, to dynamically predict the mutual correlation coefficients among modalities for instance-level feature fusion. A modal-aware hard entity replay strategy is also proposed for addressing vague entity details. Extensive experimental results show that our model not only achieves SOTA performance on multiple training scenarios including supervised, unsupervised, iterative, and low resource, but also has limited parameters, optimistic speed, and good interpretability. Our code will be available soon.

The substitute-based recommendation is widely used in E-commerce to provide better alternatives to customers. However, existing research typically uses the customer behavior signals like co-view and view-but-purchase-another to capture the substitute relationship. Despite its intuitive soundness, we find that such an approach might ignore the functionality and characteristics of products. In this paper, we adapt substitute recommendation into language matching problem by taking product title description as model input to consider product functionality. We design a new transformation method to de-noise the signals derived from production data. In addition, we consider multilingual support from the engineering point of view. Our proposed end-to-end transformer-based model achieves both successes from offline and online experiments. The proposed model has been deployed in a large-scale E-commerce website for 11 marketplaces in 6 languages. Our proposed model is demonstrated to increase revenue by 19% based on an online A/B experiment.

零击学习（ZSL）旨在预测看不见的课程，其样本在培训期间从未出现过，经常利用其他语义信息（又称侧信息）来桥接培训（见过）课程和看不见的课程。用于零拍图像分类的最有效且最广泛使用的语义信息之一是属性，是类级视觉特征的注释。但是，由于细粒度的注释短缺，属性不平衡和同时出现，当前方法通常无法区分图像之间的那些微妙的视觉区别，从而限制了它们的性能。在本文中，我们提出了一种名为Duet的基于变压器的端到端ZSL方法，该方法通过自我监督的多模式学习范式从审前的语言模型（PLM）中整合了潜在的语义知识。具体而言，我们（1）开发了一个跨模式的语义接地网络，以研究模型从图像中解开语义属性的能力，（2）应用了属性级的对比度学习策略，以进一步增强模型对细粒视觉特征的歧视反对属性的共同出现和不平衡，（3）提出了一个多任务学习策略，用于考虑多模型目标。通过对三个标准ZSL基准测试和配备ZSL基准的知识图进行广泛的实验，我们发现二重奏通常可以实现最新的性能，其组件是有效的，并且其预测是可以解释的。

卷积神经网络（CNN）的深度学习体系结构在计算机视野领域取得了杰出的成功。 CNN构建的编码器架构U-Net在生物医学图像分割方面取得了重大突破，并且已在各种实用的情况下应用。但是，编码器部分中每个下采样层和简单堆积的卷积的平等设计不允许U-NET从不同深度提取足够的特征信息。医学图像的复杂性日益增加为现有方法带来了新的挑战。在本文中，我们提出了一个更深层，更紧凑的分裂注意U形网络（DCSAU-NET），该网络有效地利用了基于两个新颖框架的低级和高级语义信息：主要功能保护和紧凑的分裂注意力堵塞。我们评估了CVC-ClinicDB，2018 Data Science Bowl，ISIC-2018和SEGPC-2021数据集的建议模型。结果，DCSAU-NET在联合（MIOU）和F1-SOCRE的平均交点方面显示出比其他最先进的方法（SOTA）方法更好的性能。更重要的是，提出的模型在具有挑战性的图像上表现出了出色的细分性能。我们的工作代码以及更多技术细节，请访问https://github.com/xq141839/dcsau-net。

最近关于多领域面部图像翻译的研究取得了令人印象深刻的结果。现有方法通常提供具有辅助分类器的鉴别器，以施加域转换。但是，这些方法忽略了关于域分布匹配的重要信息。为了解决这个问题，我们提出了一种与更自适应的鉴别器结构和匹配的发电机具有更自适应的鉴别器结构和匹配的发电机之间的开关生成的对抗网络（SwitchGan），以在多个域之间执行精密图像转换。提出了一种特征切换操作以在我们的条件模块中实现特征选择和融合。我们展示了我们模型的有效性。此外，我们还引入了发电机的新功能，该功能代表了属性强度控制，并在没有定制培训的情况下提取内容信息。在视觉上和定量地显示了Morph，RAFD和Celeba数据库的实验，表明我们扩展的SwitchGan（即，门控SwitchGan）可以实现比Stargan，Attgan和Staggan更好的翻译结果。使用培训的Reset-18模型实现的属性分类准确性和使用ImageNet预先预订的Inception-V3模型获得的FIC分数也定量展示了模型的卓越性能。

In this paper, we propose a robust 3D detector, named Cross Modal Transformer (CMT), for end-to-end 3D multi-modal detection. Without explicit view transformation, CMT takes the image and point clouds tokens as inputs and directly outputs accurate 3D bounding boxes. The spatial alignment of multi-modal tokens is performed implicitly, by encoding the 3D points into multi-modal features. The core design of CMT is quite simple while its performance is impressive. CMT obtains 73.0% NDS on nuScenes benchmark. Moreover, CMT has a strong robustness even if the LiDAR is missing. Code will be released at https://github.com/junjie18/CMT.

Dataset distillation has emerged as a prominent technique to improve data efficiency when training machine learning models. It encapsulates the knowledge from a large dataset into a smaller synthetic dataset. A model trained on this smaller distilled dataset can attain comparable performance to a model trained on the original training dataset. However, the existing dataset distillation techniques mainly aim at achieving the best trade-off between resource usage efficiency and model utility. The security risks stemming from them have not been explored. This study performs the first backdoor attack against the models trained on the data distilled by dataset distillation models in the image domain. Concretely, we inject triggers into the synthetic data during the distillation procedure rather than during the model training stage, where all previous attacks are performed. We propose two types of backdoor attacks, namely NAIVEATTACK and DOORPING. NAIVEATTACK simply adds triggers to the raw data at the initial distillation phase, while DOORPING iteratively updates the triggers during the entire distillation procedure. We conduct extensive evaluations on multiple datasets, architectures, and dataset distillation techniques. Empirical evaluation shows that NAIVEATTACK achieves decent attack success rate (ASR) scores in some cases, while DOORPING reaches higher ASR scores (close to 1.0) in all cases. Furthermore, we conduct a comprehensive ablation study to analyze the factors that may affect the attack performance. Finally, we evaluate multiple defense mechanisms against our backdoor attacks and show that our attacks can practically circumvent these defense mechanisms.
