本文提出了来自Covid-19患者CT体积的肺部感染区的分段方法。 Covid-19在全球范围内传播，造成许多受感染的患者和死亡。 CT图像的Covid-19诊断可以提供快速准确的诊断结果。肺中感染区的自动分割方法提供了诊断的定量标准。以前的方法采用整个2D图像或基于3D卷的过程。感染区域的尺寸具有相当大的变化。这种过程容易错过小型感染区域。基于补丁的过程对于分割小目标是有效的。然而，在感染区分割中选择适当的贴片尺寸难以。我们利用分段FCN的各种接受场大小之间的规模不确定性以获得感染区域。接收场尺寸可以定义为贴片尺寸和块从斑块的卷的分辨率。本文提出了一种执行基于补丁的分割的感染分段网络（ISNet）和尺度的不确定性感知预测聚合方法，其改进分割结果。我们设计ISNET到具有各种强度值的分段感染区域。 ISNet具有多个编码路径来处理由多个强度范围归一化的修补程序卷。我们收集具有各种接收场尺寸的ISNet产生的预测结果。预测聚合方法提取预测结果之间的规模不确定性。我们使用聚合FCN来在预测之间的规模不确定性来生成精确的分段结果。在我们的实验中，使用199例Covid-19案例，预测聚集方法将骰子相似度评分从47.6％提高到62.1％。

本文提出了COVID-19患者肺部肺部感染和正常区域的自动分割方法。从2019年12月起，2019年新型冠状病毒疾病（Covid-19）遍布世界，对我们的经济活动和日常生活产生重大影响。为了诊断大量感染的患者，需要计算机诊断辅助。胸部CT对于诊断病毒性肺炎，包括Covid-19是有效的。 Covid-19的诊断辅助需要从计算机的CT卷的肺部条件的定量分析方法。本文用Covid-19分割完全卷积网络（FCN）提出了来自CT卷中的CT卷中肺部感染和正常区域的自动分割方法。在诊断包括Covid-19的肺部疾病中，肺部正常和感染区域的条件分析很重要。我们的方法识别CT卷中的肺正态和感染区。对于具有各种形状和尺寸的细分感染区域，我们引入了密集的汇集连接并扩张了我们的FCN中的互联网。我们将该方法应用于Covid-19案例的CT卷。从轻度到Covid-19的严重病例，所提出的方法在肺部正确分段正常和感染区域。正常和感染区域的骰子评分分别为0.911和0.753。

Classification bandits are multi-armed bandit problems whose task is to classify a given set of arms into either positive or negative class depending on whether the rate of the arms with the expected reward of at least h is not less than w for given thresholds h and w. We study a special classification bandit problem in which arms correspond to points x in d-dimensional real space with expected rewards f(x) which are generated according to a Gaussian process prior. We develop a framework algorithm for the problem using various arm selection policies and propose policies called FCB and FTSV. We show a smaller sample complexity upper bound for FCB than that for the existing algorithm of the level set estimation, in which whether f(x) is at least h or not must be decided for every arm's x. Arm selection policies depending on an estimated rate of arms with rewards of at least h are also proposed and shown to improve empirical sample complexity. According to our experimental results, the rate-estimation versions of FCB and FTSV, together with that of the popular active learning policy that selects the point with the maximum variance, outperform other policies for synthetic functions, and the version of FTSV is also the best performer for our real-world dataset.

Diagnostic radiologists need artificial intelligence (AI) for medical imaging, but access to medical images required for training in AI has become increasingly restrictive. To release and use medical images, we need an algorithm that can simultaneously protect privacy and preserve pathologies in medical images. To develop such an algorithm, here, we propose DP-GLOW, a hybrid of a local differential privacy (LDP) algorithm and one of the flow-based deep generative models (GLOW). By applying a GLOW model, we disentangle the pixelwise correlation of images, which makes it difficult to protect privacy with straightforward LDP algorithms for images. Specifically, we map images onto the latent vector of the GLOW model, each element of which follows an independent normal distribution, and we apply the Laplace mechanism to the latent vector. Moreover, we applied DP-GLOW to chest X-ray images to generate LDP images while preserving pathologies.

In recent years, various service robots have been introduced in stores as recommendation systems. Previous studies attempted to increase the influence of these robots by improving their social acceptance and trust. However, when such service robots recommend a product to customers in real environments, the effect on the customers is influenced not only by the robot itself, but also by the social influence of the surrounding people such as store clerks. Therefore, leveraging the social influence of the clerks may increase the influence of the robots on the customers. Hence, we compared the influence of robots with and without collaborative customer service between the robots and clerks in two bakery stores. The experimental results showed that collaborative customer service increased the purchase rate of the recommended bread and improved the impression regarding the robot and store experience of the customers. Because the results also showed that the workload required for the clerks to collaborate with the robot was not high, this study suggests that all stores with service robots may show high effectiveness in introducing collaborative customer service.

This paper proposes embedded Gaussian Process Barrier States (GP-BaS), a methodology to safely control unmodeled dynamics of nonlinear system using Bayesian learning. Gaussian Processes (GPs) are used to model the dynamics of the safety-critical system, which is subsequently used in the GP-BaS model. We derive the barrier state dynamics utilizing the GP posterior, which is used to construct a safety embedded Gaussian process dynamical model (GPDM). We show that the safety-critical system can be controlled to remain inside the safe region as long as we can design a controller that renders the BaS-GPDM's trajectories bounded (or asymptotically stable). The proposed approach overcomes various limitations in early attempts at combining GPs with barrier functions due to the abstention of restrictive assumptions such as linearity of the system with respect to control, relative degree of the constraints and number or nature of constraints. This work is implemented on various examples for trajectory optimization and control including optimal stabilization of unstable linear system and safe trajectory optimization of a Dubins vehicle navigating through an obstacle course and on a quadrotor in an obstacle avoidance task using GP differentiable dynamic programming (GP-DDP). The proposed framework is capable of maintaining safe optimization and control of unmodeled dynamics and is purely data driven.

从出生到死亡，由于老化，我们都经历了令人惊讶的无处不在的变化。如果我们可以预测数字领域的衰老，即人体的数字双胞胎，我们将能够在很早的阶段检测病变，从而提高生活质量并延长寿命。我们观察到，没有一个先前开发的成年人体数字双胞胎在具有深层生成模型的体积医学图像之间明确训练的纵向转换规则，可能导致例如心室体积的预测性能不佳。在这里，我们建立了一个新的成人人体的数字双胞胎，该数字双胞胎采用纵向获得的头部计算机断层扫描（CT）图像进行训练，从而从一个当前的体积头CT图像中预测了未来的体积头CT图像。我们首次采用了三维基于流动的深层生成模型之一，以实现这种顺序的三维数字双胞胎。我们表明，我们的数字双胞胎在相对较短的程度上优于预测心室体积的最新方法。

在本文中，我们报告了一项现场研究，在该研究中，我们在面包店使用了两个服务机器人作为促销活动。先前的研究探索了公共公共公众公共应用，例如购物中心。但是，需要更多的证据表明，服务机器人可以为真实商店的销售做出贡献。此外，在促销促销的背景下，客户和服务机器人的行为尚未得到很好的检查。因此，可以认为有效的机器人行为类型，并且客户对这些机器人的反应尚不清楚。为了解决这些问题，我们在面包店安装了两个远程操作的服务机器人将近2周，一个在入口处作为招待员，另一个在商店里推荐产品。结果表明，在应用机器人时，销售额急剧增加。此外，我们注释了机器人和客户行为的视频录制。我们发现，尽管放置在入口处的机器人成功吸引了路人的兴趣，但没有观察到访问商店的客户数量明显增加。但是，我们确认商店内部运行的机器人的建议确实产生了积极影响。我们详细讨论我们的发现，并为未来的研究和应用提供理论和实用建议。

自动基于图像的疾病严重程度估计通常使用离散（即量化）严重性标签。由于图像含糊不清，因此通常很难注释离散标签。一个更容易的替代方法是使用相对注释，该注释比较图像对之间的严重程度。通过使用带有相对注释的学习对框架，我们可以训练一个神经网络，该神经网络估计与严重程度相关的等级分数。但是，所有可能对的相对注释都是过敏的，因此，适当的样品对选择是强制性的。本文提出了深层贝叶斯的主动学习与级别，该级别训练贝叶斯卷积神经网络，同时自动选择合适的对进行相对注释。我们通过对溃疡性结肠炎的内窥镜图像进行实验证实了该方法的效率。此外，我们确认我们的方法即使在严重的类失衡中也很有用，因为它可以自动从次要类中选择样本。
