在“知识图”（kgs）的表示领域中，超级关系的事实由主要三重和几个辅助属性描述组成，这被认为比基于三重的事实更全面，更具体。但是，由于代表实体之间的隶属关系的层次结构削弱，因此，单个视图中现有的超相关KG嵌入方法受到限制。为了打破这一限制，我们提出了一个双视性超相关kg（DH-kg）结构，该结构包含实体的超相关实例视图，以及对从实体到共同模型超相关的概念的超相关本体论视图和分层信息。在本文中，我们首先定义了DH-KG上的链接预测和实体键入任务，并根据医疗数据构建了两个DH-KG数据集，即从Wikidata和HTDM中提取的JW44K-6K。此外，我们根据Gran编码器，HGNN和联合学习提出了DH-KG嵌入模型DHGE。实验结果表明，DHGE在DH-KG上的表现优于基线模型。我们还提供了该技术在高血压药物领域中应用的示例。我们的模型和数据集公开可用。

最近，由于其灵活和兼容的结构，软机器人技术已迅速成为一个新颖而有希望的研究领域。但是，更难得出这种软机器人的非线性动态模型。软操作器的差分运动学和动力学可以通过经典的Cosserat Rod理论配制为一组高度非线性的部分微分方程（PDE）。在这项工作中，我们提出了一种称为分段线性应变（PLS）的离散建模技术，以解决基于Cosserat的模型的PDE，该模型基于该模型的推导。为了验证所提出的cosserat模型的准确性，通过使用不同的离散方法模拟了重力下的锥形悬臂杆的静态模型。结果表明，PLS cosserat模型与现实世界软操作器的机械变形行为相媲美。最后，建立了该模型的参数识别方案，模拟以及实验验证表明，使用此方法可以以高精度识别模型物理参数。

当前的最佳性能模型用于知识图推理（KGR）将几何学对象或概率分布引入嵌入实体，并将一阶逻辑（fol）查询引入低维矢量空间。它们可以总结为中心尺寸框架（点/框/锥，β/高斯分布等）。但是，它们具有有限的逻辑推理能力。而且很难概括到各种功能，因为中心和大小是一对一的约束，无法具有多个中心或尺寸。为了应对这些挑战，我们相反提出了一个名为“特征逻辑嵌入框架Flex”的新颖的KGR框架，这是第一个KGR框架，它不仅可以真正处理所有运营，包括连词，析取，否定，否定等等，而且还支持各种操作特征空间。具体而言，特征逻辑框架的逻辑部分是基于向量逻辑的，它自然地对所有FOL操作进行了建模。实验表明，FLEX在基准数据集上明显优于现有的最新方法。

特征图的分辨率对于医学图像分割至关重要。大多数现有用于医疗图像分割的基于变压器的网络都是U-NET样体系结构，其中包含一个编码器，该编码器利用一系列变压器块将输入医疗图像从高分辨率表示形式转换为低分辨率特征图和解码器这逐渐从低分辨率特征图中恢复了高分辨率表示。与以前的研究不同，在本文中，我们利用高分辨率网络（HRNET）的网络设计样式，用变压器块替换卷积层，并从变压器块生成的不同分辨率特征图中连续交换信息。本文介绍的新基于变压器的网络表示为高分辨率SWIN Transformer网络（HRSTNET）。广泛的实验表明，HRSTNET可以与基于最新的变压器类似于脑肿瘤分割的U-NET样结构（BRATS）2021和Medical Sementation Decathlon的肝数据集实现可比的性能。 HRSTNET代码将在https://github.com/auroua/hrstnet上公开获得。

使用深神经网络的自动诊断可以帮助眼科医生检测致盲眼病湿时期相关的黄斑变性（AMD）。湿AMD具有两种类似的亚型，新生血管和息肉脉络膜（PCV）。然而，由于数据收集困难和图像之间的相似性，大多数研究仅达到了湿-amd的粗粒粒度，而不是湿-amd亚型中的细粒。为了解决这个问题，在本文中，我们提出了一种知识驱动的细粒度湿法AMD分类模型（KFWC），以对数据不足的细粒疾病进行分类。随着将输入图像的10个病变迹象的先验知识引入KFWC，我们的目标是通过多标签分类预培训加速KFWC，以定位细粒疾病分类任务中的决定性图像特征因此实现了更好的分类。同时，KFWC还可以提供良好的可解释性，并有效地减轻湿法菌疾病分类领域的数据收集和注释压力。实验证明了澳大利亚委员会的持续99.71％的有效性，以及对数据驱动的W / O知识和眼科医生相当大的改进，比最强的基线和4.14％对眼科医生的速度为6.69％。

分子表示学习有助于多个下游任务，例如分子性质预测和药物设计。为了适当地代表分子，图形对比学习是一个有前途的范式，因为它利用自我监督信号并没有人类注释要求。但是，先前的作品未能将基本域名知识纳入图表语义，因此忽略了具有共同属性的原子之间的相关性，但不通过键连接连接。为了解决这些问题，我们构建化学元素知识图（KG），总结元素之间的微观关联，并提出了一种用于分子代表学习的新颖知识增强的对比学习（KCL）框架。 KCL框架由三个模块组成。第一个模块，知识引导的图形增强，基于化学元素kg增强原始分子图。第二模块，知识意识的图形表示，利用用于原始分子图的公共曲线图编码器和通过神经网络（KMPNN）的知识感知消息来提取分子表示来编码增强分子图中的复杂信息。最终模块是一种对比目标，在那里我们在分子图的这两个视图之间最大化协议。广泛的实验表明，KCL获得了八个分子数据集上的最先进基线的优异性能。可视化实验适当地解释了在增强分子图中从原子和属性中了解的KCL。我们的代码和数据可用于补充材料。

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.

Automatic music generation with artificial intelligence typically requires a large amount of data which is hard to obtain for many less common genres and musical instruments. To tackle this issue, we present ongoing work and preliminary findings on the possibility for deep models to transfer knowledge from language to music, by finetuning large language models pre-trained on a massive text corpus on only hundreds of MIDI files of drum performances. We show that by doing so, one of the largest, state-of-the-art models (GPT3) is capable of generating reasonable drum grooves, while models that are not pre-trained (Transformer) shows no such ability beyond naive repetition. Evaluating generated music is a challenging task, more so is evaluating drum grooves with little precedence in literature. Hence, we propose a tailored structural evaluation method and analyze drum grooves produced by GPT3 compared to those played by human professionals, exposing the strengths and weaknesses of such generation by language-to-music transfer. Our findings suggest that language-to-music transfer learning with large language models is viable and promising.

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.
