在本研究中，我们提出了一种基于病例的新型图像检索（SIR）方法，用于苏木精和曙红（H＆E）染色的恶性淋巴瘤的组织病理学图像。当将整个幻灯片图像（WSI）用作输入查询时，希望能够通过重点关注病理上重要区域（例如肿瘤细胞）中的图像斑块来检索相似情况。为了解决这个问题，我们采用了基于注意力的多个实例学习，这使我们能够在计算案例之间的相似性时专注于肿瘤特异性区域。此外，我们采用对比度距离度量学习将免疫组织化学（IHC）染色模式纳入有用的监督信息，以定义异质性恶性淋巴瘤病例之间的适当相似性。在对249例恶性淋巴瘤患者的实验中，我们证实该方法比基线基于病例的SIR方法表现出更高的评估措施。此外，病理学家的主观评估表明，我们使用IHC染色模式的相似性度量适用于代表恶性淋巴瘤H＆E染色组织图像的相似性。

Pre-trained language models, despite their rapid advancements powered by scale, still fall short of robust commonsense capabilities. And yet, scale appears to be the winning recipe; after all, the largest models seem to have acquired the largest amount of commonsense capabilities. Or is it? In this paper, we investigate the possibility of a seemingly impossible match: can smaller language models with dismal commonsense capabilities (i.e., GPT-2), ever win over models that are orders of magnitude larger and better (i.e., GPT-3), if the smaller models are powered with novel commonsense distillation algorithms? The key intellectual question we ask here is whether it is possible, if at all, to design a learning algorithm that does not benefit from scale, yet leads to a competitive level of commonsense acquisition. In this work, we study the generative models of commonsense knowledge, focusing on the task of generating generics, statements of commonsense facts about everyday concepts, e.g., birds can fly. We introduce a novel commonsense distillation framework, I2D2, that loosely follows the Symbolic Knowledge Distillation of West et al. but breaks the dependence on the extreme-scale models as the teacher model by two innovations: (1) the novel adaptation of NeuroLogic Decoding to enhance the generation quality of the weak, off-the-shelf language models, and (2) self-imitation learning to iteratively learn from the model's own enhanced commonsense acquisition capabilities. Empirical results suggest that scale is not the only way, as novel algorithms can be a promising alternative. Moreover, our study leads to a new corpus of generics, Gen-A-Tomic, that is of the largest and highest quality available to date.

We consider task allocation for multi-object transport using a multi-robot system, in which each robot selects one object among multiple objects with different and unknown weights. The existing centralized methods assume the number of robots and tasks to be fixed, which is inapplicable to scenarios that differ from the learning environment. Meanwhile, the existing distributed methods limit the minimum number of robots and tasks to a constant value, making them applicable to various numbers of robots and tasks. However, they cannot transport an object whose weight exceeds the load capacity of robots observing the object. To make it applicable to various numbers of robots and objects with different and unknown weights, we propose a framework using multi-agent reinforcement learning for task allocation. First, we introduce a structured policy model consisting of 1) predesigned dynamic task priorities with global communication and 2) a neural network-based distributed policy model that determines the timing for coordination. The distributed policy builds consensus on the high-priority object under local observations and selects cooperative or independent actions. Then, the policy is optimized by multi-agent reinforcement learning through trial and error. This structured policy of local learning and global communication makes our framework applicable to various numbers of robots and objects with different and unknown weights, as demonstrated by numerical simulations.

Artificial life is a research field studying what processes and properties define life, based on a multidisciplinary approach spanning the physical, natural and computational sciences. Artificial life aims to foster a comprehensive study of life beyond "life as we know it" and towards "life as it could be", with theoretical, synthetic and empirical models of the fundamental properties of living systems. While still a relatively young field, artificial life has flourished as an environment for researchers with different backgrounds, welcoming ideas and contributions from a wide range of subjects. Hybrid Life is an attempt to bring attention to some of the most recent developments within the artificial life community, rooted in more traditional artificial life studies but looking at new challenges emerging from interactions with other fields. In particular, Hybrid Life focuses on three complementary themes: 1) theories of systems and agents, 2) hybrid augmentation, with augmented architectures combining living and artificial systems, and 3) hybrid interactions among artificial and biological systems. After discussing some of the major sources of inspiration for these themes, we will focus on an overview of the works that appeared in Hybrid Life special sessions, hosted by the annual Artificial Life Conference between 2018 and 2022.

Analyzing defenses in team sports is generally challenging because of the limited event data. Researchers have previously proposed methods to evaluate football team defense by predicting the events of ball gain and being attacked using locations of all players and the ball. However, they did not consider the importance of the events, assumed the perfect observation of all 22 players, and did not fully investigated the influence of the diversity (e.g., nationality and sex). Here, we propose a generalized valuation method of defensive teams by score-scaling the predicted probabilities of the events. Using the open-source location data of all players in broadcast video frames in football games of men's Euro 2020 and women's Euro 2022, we investigated the effect of the number of players on the prediction and validated our approach by analyzing the games. Results show that for the predictions of being attacked, scoring, and conceding, all players' information was not necessary, while that of ball gain required information on three to four offensive and defensive players. With game analyses we explained the excellence in defense of finalist teams in Euro 2020. Our approach might be applicable to location data from broadcast video frames in football games.

To ensure the safety of railroad operations, it is important to monitor and forecast track geometry irregularities. A higher safety requires forecasting with a higher spatiotemporal frequency. For forecasting with a high spatiotemporal frequency, it is necessary to capture spatial correlations. Additionally, track geometry irregularities are influenced by multiple exogenous factors. In this study, we propose a method to forecast one type of track geometry irregularity, vertical alignment, by incorporating spatial and exogenous factor calculations. The proposed method embeds exogenous factors and captures spatiotemporal correlations using a convolutional long short-term memory (ConvLSTM). In the experiment, we compared the proposed method with other methods in terms of the forecasting performance. Additionally, we conducted an ablation study on exogenous factors to examine their contribution to the forecasting performance. The results reveal that spatial calculations and maintenance record data improve the forecasting of the vertical alignment.

有一段漫长的历史，努力与我们周围的实体和空间探索音乐元素，例如Musique Concr \'Ete和Ambient Music。在计算机音乐和数字艺术的背景下，还设计了集中在周围物体和物理空间上的互动体验。近年来，随着设备的开发和普及，在扩展现实中设计了越来越多的作品，以创造这种音乐体验。在本文中，我们描述了MR4MR，这是一项声音安装工作，使用户可以在混合现实的背景下体验与周围空间相互作用产生的旋律（MR）。用户使用HoloLens，用户可以撞击周围环境中真实对象的虚拟对象。然后，通过遵循物体发出的声音并使用音乐生成机器学习模型进行随机变化并逐渐改变旋律的声音，用户可以感觉到其环境旋律“转世”。

我们提出了一个名为“ Visual配方流”的新的多模式数据集，使我们能够学习每个烹饪动作的结果。数据集由对象状态变化和配方文本的工作流程组成。状态变化表示为图像对，而工作流则表示为食谱流图（R-FG）。图像对接地在R-FG中，该R-FG提供了交叉模式关系。使用我们的数据集，可以尝试从多模式常识推理和程序文本生成来尝试一系列应用程序。

通常，通过聚类或订购将标签分配给每个元素，通常可以分析关系数据集。尽管通过聚类和排序方法可以实现数据集的类似表征，但前者比后者更积极地研究了数据集，尤其是对于表示为图的数据。这项研究通过研究几种聚类和订购方法之间的方法学关系来填补这一空白，重点是光谱技术。此外，我们评估了聚类和订购方法的结果性能。为此，我们提出了一种称为标签连续性误差的度量，该度量通常量化了一组元素的序列和分区之间的一致性程度。基于合成和现实世界数据集，我们评估了订购方法标识模块结构和聚类方法标识带状结构的范围。

在本文中，我们考虑在对每个群集建模时，即基于模型的时间序列群集时，将一组单个时间序列集群的任务。该任务需要一个具有足够灵活性的参数模型来描述各个时间序列中的动力学。为了解决这个问题，我们提出了一种基于模型的时间序列聚类方法，该方法具有线性高斯状态空间模型的混合物，具有很高的灵活性。提出的方法对混合模型使用一种新的期望最大化算法来估计模型参数，并使用贝叶斯信息标准确定簇数。模拟数据集上的实验证明了该方法在聚类，参数估计和模型选择中的有效性。该方法应用于真实的数据集，该数据集以前提出的时间序列聚类方法表现出低精度。结果表明，与使用先前方法获得的方法相比，我们的方法产生的聚类结果更准确。
