知识图完成（KGC）旨在发现知识图（KGS）中实体之间的缺失关系。大多数先前的KGC工作都集中在实体和关系的学习表现上。然而，通常需要更高维度的嵌入空间才能获得更好的推理能力，这会导致更大的模型大小，并阻碍对现实世界中的问题的适用性（例如，大规模kgs或移动/边缘计算）。在这项工作中提出了一种称为GreenKGC的轻型模块化的KGC解决方案，以解决此问题。 GreenKGC由三个模块组成：1）表示学习，2）特征修剪和3）决策学习。在模块1中，我们利用现有的KG嵌入模型来学习实体和关系的高维表示。在模块2中，KG分为几个关系组，然后分为一个特征修剪过程，以找到每个关系组的最判别特征。最后，将分类器分配给每个关系组，以应对模块3中KGC任务的低维三功能原始的高维嵌入型号尺寸较小。此外，我们对两个三重分类数据集进行了实验，以证明相同的方法可以推广到更多任务。

翻译，旋转和缩放是图像处理中三个常用的几何操作操作。此外，其中一些成功用于开发有效的知识图嵌入（KGE）模型，例如transe和旋转。受协同作用的启发，我们通过利用这项工作中的所有三项操作提出了一个新的KGE模型。由于翻译，旋转和缩放操作被级联形成一个复合的操作，因此新模型被命名为复合。通过在小组理论的框架中铸造复合物，我们表明，基于得分功能的KGE模型是复合的特殊情况。Compounde将简单的基于距离的关系扩展到与关系有关的化合物操作上的头部和/或尾部实体。为了证明化合物的有效性，我们对三个流行的KG完成数据集进行了实验。实验结果表明，复合者始终达到了现状的性能。

近年来，深入学习数据隐私的重要性取得了重大关注。在缺乏金融监管机构的监督时，申请深度学习时可能会遭受数据泄露。然而，金融领域几乎没有相对的研究，我们最好的知识。我们将谷歌提出的两位代表深度学习隐私框架应用于金融交易数据。我们设计了从原始研究中提出的几个不同参数的实验。此外，我们将谷歌和苹果公司的隐私程度推荐给更合理地估计结果。结果表明，DP-SGD比金融交易数据的展开框架更好。隐私和准确性之间的权衡在DP-SGD中低。隐私程度也符合实际情况。因此，我们可以通过精确度获得强大的隐私保障，以避免潜在的经济损失。

实体类型预测是知识图中的一个重要问题（kg）研究。在这项工作中提出了一种新的KG实体类型预测方法，名为Core（复杂的空间回归和嵌入）。所提出的核心方法利用两个复杂空间嵌入模型的表现力;即，旋转和复杂的模型。它使用旋转或复杂地将实体和类型嵌入两个不同的复杂空间中。然后，我们推导了一个复杂的回归模型来链接这两个空格。最后，介绍了一种优化嵌入和回归参数的机制。实验表明，核心优于代表性KG实体型推理数据集的基准测试方法。分析了各种实体型预测方法的强度和弱点。

知识库完成在这项工作中被制定为二进制分类问题，其中使用知识图中的相关链接（KGS）培训XGBoost二进制分类器。新方法名为KGBoost，采用模块化设计，并尝试找到硬阴性样本，以便培训强大的分类器以进行缺失链路预测。我们在多个基准数据集中进行实验，并证明KGBoost在大多数数据集中优于最先进的方法。此外，与端到端优化训练的模型相比，kgboost在低维设置下运行良好，以便允许更小的型号尺寸。

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.

Knowledge graphs (KG) have served as the key component of various natural language processing applications. Commonsense knowledge graphs (CKG) are a special type of KG, where entities and relations are composed of free-form text. However, previous works in KG completion and CKG completion suffer from long-tail relations and newly-added relations which do not have many know triples for training. In light of this, few-shot KG completion (FKGC), which requires the strengths of graph representation learning and few-shot learning, has been proposed to challenge the problem of limited annotated data. In this paper, we comprehensively survey previous attempts on such tasks in the form of a series of methods and applications. Specifically, we first introduce FKGC challenges, commonly used KGs, and CKGs. Then we systematically categorize and summarize existing works in terms of the type of KGs and the methods. Finally, we present applications of FKGC models on prediction tasks in different areas and share our thoughts on future research directions of FKGC.

Few Shot Instance Segmentation (FSIS) requires models to detect and segment novel classes with limited several support examples. In this work, we explore a simple yet unified solution for FSIS as well as its incremental variants, and introduce a new framework named Reference Twice (RefT) to fully explore the relationship between support/query features based on a Transformer-like framework. Our key insights are two folds: Firstly, with the aid of support masks, we can generate dynamic class centers more appropriately to re-weight query features. Secondly, we find that support object queries have already encoded key factors after base training. In this way, the query features can be enhanced twice from two aspects, i.e., feature-level and instance-level. In particular, we firstly design a mask-based dynamic weighting module to enhance support features and then propose to link object queries for better calibration via cross-attention. After the above steps, the novel classes can be improved significantly over our strong baseline. Additionally, our new framework can be easily extended to incremental FSIS with minor modification. When benchmarking results on the COCO dataset for FSIS, gFSIS, and iFSIS settings, our method achieves a competitive performance compared to existing approaches across different shots, e.g., we boost nAP by noticeable +8.2/+9.4 over the current state-of-the-art FSIS method for 10/30-shot. We further demonstrate the superiority of our approach on Few Shot Object Detection. Code and model will be available.

Graph Neural Networks (GNNs) have shown satisfying performance on various graph learning tasks. To achieve better fitting capability, most GNNs are with a large number of parameters, which makes these GNNs computationally expensive. Therefore, it is difficult to deploy them onto edge devices with scarce computational resources, e.g., mobile phones and wearable smart devices. Knowledge Distillation (KD) is a common solution to compress GNNs, where a light-weighted model (i.e., the student model) is encouraged to mimic the behavior of a computationally expensive GNN (i.e., the teacher GNN model). Nevertheless, most existing GNN-based KD methods lack fairness consideration. As a consequence, the student model usually inherits and even exaggerates the bias from the teacher GNN. To handle such a problem, we take initial steps towards fair knowledge distillation for GNNs. Specifically, we first formulate a novel problem of fair knowledge distillation for GNN-based teacher-student frameworks. Then we propose a principled framework named RELIANT to mitigate the bias exhibited by the student model. Notably, the design of RELIANT is decoupled from any specific teacher and student model structures, and thus can be easily adapted to various GNN-based KD frameworks. We perform extensive experiments on multiple real-world datasets, which corroborates that RELIANT achieves less biased GNN knowledge distillation while maintaining high prediction utility.

This paper focuses on designing efficient models with low parameters and FLOPs for dense predictions. Even though CNN-based lightweight methods have achieved stunning results after years of research, trading-off model accuracy and constrained resources still need further improvements. This work rethinks the essential unity of efficient Inverted Residual Block in MobileNetv2 and effective Transformer in ViT, inductively abstracting a general concept of Meta-Mobile Block, and we argue that the specific instantiation is very important to model performance though sharing the same framework. Motivated by this phenomenon, we deduce a simple yet efficient modern \textbf{I}nverted \textbf{R}esidual \textbf{M}obile \textbf{B}lock (iRMB) for mobile applications, which absorbs CNN-like efficiency to model short-distance dependency and Transformer-like dynamic modeling capability to learn long-distance interactions. Furthermore, we design a ResNet-like 4-phase \textbf{E}fficient \textbf{MO}del (EMO) based only on a series of iRMBs for dense applications. Massive experiments on ImageNet-1K, COCO2017, and ADE20K benchmarks demonstrate the superiority of our EMO over state-of-the-art methods, \eg, our EMO-1M/2M/5M achieve 71.5, 75.1, and 78.4 Top-1 that surpass \textbf{SoTA} CNN-/Transformer-based models, while trading-off the model accuracy and efficiency well.
