自适应共振理论（ART）被认为是实现持续学习的有效方法，这要归功于其处理可塑性稳定性困境的能力。但是，通常，基于艺术的算法的聚类性能很大程度上取决于相似性阈值的规范，即警惕参数，该参数是数据依赖性和手工指定的。本文提出了一种基于艺术的拓扑聚类算法，其机制自动估计数据点分布的相似性阈值。此外，为了改善信息提取性能，通过向所提出的算法引入层次结构，提出了一种能够连续学习的分裂层次聚类算法。实验结果表明，所提出的算法具有与最近提供的最先进的层次聚类算法相当的高聚类性能。

Large-scale vision-language models such as CLIP have shown impressive performance on zero-shot image classification and image-to-text retrieval. However, such zero-shot performance of CLIP-based models does not realize in tasks that require a finer-grained correspondence between vision and language, such as Visual Question Answering (VQA). We investigate why this is the case, and report an interesting phenomenon of CLIP, which we call the Concept Association Bias (CAB), as a potential cause of the difficulty of applying CLIP to VQA and similar tasks. CAB is especially apparent when two concepts are present in the given image while a text prompt only contains a single concept. In such a case, we find that CLIP tends to treat input as a bag of concepts and attempts to fill in the other missing concept crossmodally, leading to an unexpected zero-shot prediction. For example, when asked for the color of a lemon in an image, CLIP predicts ``purple'' if the image contains a lemon and an eggplant. We demonstrate the Concept Association Bias of CLIP by showing that CLIP's zero-shot classification performance greatly suffers when there is a strong concept association between an object (e.g. lemon) and an attribute (e.g. its color). On the other hand, when the association between object and attribute is weak, we do not see this phenomenon. Furthermore, we show that CAB is significantly mitigated when we enable CLIP to learn deeper structure across image and text embeddings by adding an additional Transformer on top of CLIP and fine-tuning it on VQA. We find that across such fine-tuned variants of CLIP, the strength of CAB in a model predicts how well it performs on VQA.

A practical issue of edge AI systems is that data distributions of trained dataset and deployed environment may differ due to noise and environmental changes over time. Such a phenomenon is known as a concept drift, and this gap degrades the performance of edge AI systems and may introduce system failures. To address this gap, a retraining of neural network models triggered by concept drift detection is a practical approach. However, since available compute resources are strictly limited in edge devices, in this paper we propose a lightweight concept drift detection method in cooperation with a recently proposed on-device learning technique of neural networks. In this case, both the neural network retraining and the proposed concept drift detection are done by sequential computation only to reduce computation cost and memory utilization. Evaluation results of the proposed approach shows that while the accuracy is decreased by 3.8%-4.3% compared to existing batch-based detection methods, it decreases the memory size by 88.9%-96.4% and the execution time by 1.3%-83.8%. As a result, the combination of the neural network retraining and the proposed concept drift detection method is demonstrated on Raspberry Pi Pico that has 264kB memory.

Applying suction grippers in unstructured environments is a challenging task because of depth and tilt errors in vision systems, requiring additional costs in elaborate sensing and control. To reduce additional costs, suction grippers with compliant bodies or mechanisms have been proposed; however, their bulkiness and limited allowable error hinder their use in complex environments with large errors. Here, we propose a compact suction gripper that can pick objects over a wide range of distances and tilt angles without elaborate sensing and control. The spring-inserted gripper body deploys and conforms to distant and tilted objects until the suction cup completely seals with the object and retracts immediately after, while holding the object. This seamless deployment and retraction is enabled by connecting the gripper body and suction cup to the same vacuum source, which couples the vacuum picking and retraction of the gripper body. Experimental results validated that the proposed gripper can pick objects within 79 mm, which is 1.4 times the initial length, and can pick objects with tilt angles up to 60{\deg}. The feasibility of the gripper was verified by demonstrations, including picking objects of different heights from the same picking height and the bin picking of transparent objects.

研究过程包括许多决定，例如如何应有资格以及在何处发表论文。在本文中，我们介绍了一个一般框架，以调查此类决策的影响。研究效果的主要困难是我们需要了解反事实结果，而实际上并非现实。我们框架的主要见解是灵感来自现有的反事实分析，其中研究人员将双胞胎视为反事实单位。提出的框架将一对彼此引用为双胞胎的论文。这些论文往往是平行的作品，在类似的主题和类似社区中。我们调查了采用不同决策的双论文，观察这些研究带来的研究影响的进展，并通过这些研究的影响来估算决策的影响。我们发布了我们的代码和数据，我们认为由于数据集缺乏反事实研究，因此这是非常有益的。

三维（3D）医学图像的产生可能具有巨大的应用潜力，因为它考虑了3D解剖结构。但是，有两个问题可以防止有效培训3D医疗生成模型：（1）3D医学图像的获取和注释非常昂贵，导致培训图像不足，（2）大量参数是参与3D卷积。为了解决这两个问题，我们提出了一种名为3D Split＆Shuffle-Gan的新型GAN模型。为了解决3D数据稀缺问题，我们首先使用丰富的图像切片预先培训二维（2D）GAN模型，并夸大2D卷积权重以改善3D GAN的初始化。为GAN模型的生成器和鉴别器提出了新型的3D网络体系结构，以显着减少参数的数量，同时保持图像生成的质量。研究了许多体重通胀策略和参数有效的3D架构。对心脏（Stanford Aimi冠状动脉钙）和大脑（阿尔茨海默氏病神经成像计划）的实验表明，所提出的方法会导致改善的3D图像产生质量，参数较少。

域的概括（DG）旨在在一个或多个不同但相关的源域上学习一个模型，这些模型可以推广到看不见的目标域。现有的DG方法试图提示模型的概括能力的源域的多样性，同时他们可能必须引入辅助网络或达到计算成本。相反，这项工作应用了特征空间中的隐式语义增强来捕获源域的多样性。具体来说，包括距离度量学习（DML）的附加损失函数，以优化数据分布的局部几何形状。此外，采用跨熵损失的逻辑被无限增强作为DML损失的输入特征，以代替深度特征。我们还提供了理论分析，以表明逻辑可以近似于原始特征上定义的距离。此外，我们对方法背后的机制和理性进行了深入的分析，这使我们可以更好地了解为什么要代替特征的杠杆逻辑可以帮助域的概括。拟议的DML损失与隐式增强作用纳入了最近的DG方法中，即傅立叶增强联合老师框架（FACT）。同时，我们的方法也可以轻松地插入各种DG方法中。对三个基准测试（Digits-DG，PAC和办公室家庭）进行的广泛实验表明，该建议的方法能够实现最新的性能。

自我监督学习的最新发展使我们有可能进一步减少人类干预的多步管道中的干预，其中重点围绕着特定感兴趣的对象而发展。在本文中，焦点在组织病理学图像中的细胞核中放置。特别是，我们旨在以无监督的方式提取蜂窝信息，以完成下游任务。随着核以各种尺寸表现出来，我们提出了一个新的依赖量表卷积层来绕过调整核时尺寸的问题。在三个核数据集上，我们基准了以下方法：手工制作的，预先训练的重新系统，有监督的重新系统和自我监督的特征。我们表明，所提出的卷积层提高了性能，并且与Barlows-Twins结合使用，与低样本设置中的监督范式相比，该层可以更好地编码核编码，并且胜过所有其他建议的无监督方法。此外，我们将现有的TNBC数据集扩展到合并核类别的注释，以丰富和公开释放一个小样本设置数据集以进行核分割和分类。

捍卫深层神经网络免受对抗性示例是AI安全的关键挑战。为了有效地提高鲁棒性，最近的方法集中在对抗训练中的决策边界附近的重要数据点上。但是，这些方法容易受到自动攻击的影响，这是无参数攻击的合奏，可用于可靠评估。在本文中，我们通过实验研究了其脆弱性的原因，发现现有方法会减少真实标签和其他标签的逻辑之间的利润，同时保持其梯度规范非微小值。减少的边缘和非微小梯度规范会导致其脆弱性，因为最大的logit可以轻松地被扰动翻转。我们的实验还表明，logit边缘的直方图具有两个峰，即小和大的logit边缘。从观察结果来看，我们提出了切换单重损失（SOVR），当数据具有较小的logit rumgins时，它会使用单重损失，从而增加边缘。我们发现，SOVR比现有方法增加了logit的利润率，同时使梯度规范保持较小，并且在针对自动攻击的鲁棒性方面超越了它们。

我们引入了责任感敏感安全性（RSS）的目标延长，这是一种基于规则的自动驾驶系统安全保证（ADS）的方法。制定RSS规则保证目标实现 - 除了原始RSS中的避免碰撞外，还需要进行长时间的操纵序列的复杂计划。为了应对复杂性，我们基于程序逻辑引入了一个构图推理框架，其中可以系统地为较小的子赛车制定RSS规则，并将它们组合起来以获取用于较大场景的RSS规则。作为框架的基础，我们介绍了一个程序逻辑DFHL，可满足连续的动态和安全条件。我们的框架介绍了基于DFHL的工作流程，用于导出目标感知RSS规则；我们也讨论其软件支持。我们在安全体系结构中使用RSS规则进行了实验评估。它的结果表明，目标感知RSS确实有效地实现了避免碰撞和目标实现目标。
