准确的语义分割模型通常需要大量的计算资源，从而抑制其在实际应用中的使用。最近的作品依靠精心制作的轻质模型来快速推断。但是，这些模型不能灵活地适应不同的准确性和效率要求。在本文中，我们提出了一种简单但有效的微小语义细分（SLIMSEG）方法，该方法可以在推理期间以不同的能力执行，具体取决于所需的准确性效率 - 折衷。更具体地说，我们在训练过程中采用逐步向下知识蒸馏采用参数化通道。观察到每个子模型的分割结果之间的差异主要在语义边界附近，我们引入了额外的边界指导语义分割损失，以进一步提高每个子模型的性能。我们表明，我们提出的具有各种主流网络的Slimseg可以产生灵活的模型，从而使计算成本的动态调整和比独立模型更好。关于语义分割基准，城市景观和Camvid的广泛实验证明了我们框架的概括能力。

在本文中，我们提出了一个生成的对抗网络（GAN）框架，以增强压缩视频的感知质量。我们的框架包括单个模型中对不同量化参数（QP）的注意和适应。注意模块利用了可以捕获和对齐连续框架之间的远程相关性的全球接收场，这可能有益于提高视频感知质量。要增强的框架与其相邻的框架一起馈入深网，并在第一阶段的特征中提取不同深度的特征。然后提取的特征被馈入注意力块以探索全局的时间相关性，然后进行一系列上采样和卷积层。最后，通过利用相应的QP信息的QP条件适应模块处理所得的功能。这样，单个模型可用于增强对各种QP的适应性，而无需针对每个QP值的多个模型，同时具有相似的性能。实验结果表明，与最先进的压缩视频质量增强算法相比，所提出的PEQUENET的表现出色。

使用机器学习的数据驱动的范例在图像处理和通信中变得普遍存在。特别地，图像到图像（I2I）转换是一种通用和广泛使用的图像处理问题的方法，例如图像合成，样式传输和图像恢复。同时，神经图像压缩被出现为可视通信中传统编码方法的数据驱动替代方法。在本文中，我们将这两种范例的组合与联合I2I压缩和翻译框架一起研究，重点是多域图像合成。首先通过将量化和熵编码集成到I2I翻译框架（即i2iCodec）中提出分布式I2I转换。在实践中，也希望图像压缩功能（即自动编码），需要与常规图像编解码器一起部署。因此，我们进一步提出了一个统一的框架，其允许在单个编解码器中进行平移和自动编码功能。在翻译/压缩模式下调节的自适应残差块提供灵活的适应性对所需功能。实验表明，使用单个模型的I2I平移和图像压缩均有前景。

大多数元学习方法都假设存在于可用于基本知识的情节元学习的一组非常大的标记数据。这与更现实的持续学习范例形成对比，其中数据以包含不相交类的任务的形式逐步到达。在本文中，我们考虑了这个增量元学习（IML）的这个问题，其中类在离散任务中逐步呈现。我们提出了一种方法，我们调用了IML，我们称之为eCISODIC重播蒸馏（ERD），该方法将来自当前任务的类混合到当前任务中，当研究剧集时，来自先前任务的类别示例。然后将这些剧集用于知识蒸馏以最大限度地减少灾难性的遗忘。四个数据集的实验表明ERD超越了最先进的。特别是，在一次挑战的单次次数较挑战，长任务序列增量元学习场景中，我们将IML和联合训练与当前状态的3.5％/ 10.1％/ 13.4％之间的差距降低我们在Diered-ImageNet / Mini-ImageNet / CIFAR100上分别为2.6％/ 2.9％/ 5.0％。

域适应（DA）旨在缓解源域和目标域之间的域移位。大多数DA方法都需要访问源数据，但通常是不可能的（例如，由于数据隐私或知识产权）。在本文中，我们解决了挑战的无源域适应（SFDA）问题，其中源净定模型在没有源数据的情况下适应目标域。我们的方法基于目标数据的观察，该数据可能不再与源域分类器对齐，仍然形成清晰的群集。我们通过定义目标数据的本地亲和力来捕获此内在结构，并鼓励具有高局部亲和力的数据之间的标签一致性。我们观察到应将更高的亲和力分配给互惠邻居，并提出自正规化损失以减少嘈杂邻居的负面影响。此外，要使用更多上下文聚合信息，我们考虑扩展的邻域，具有小关联值。在实验结果中，我们验证了目标特征的固有结构是域适应的重要信息来源。我们证明可以通过考虑本地邻居，互易邻居和扩展的邻域来有效地捕获该局部结构。最后，我们在几个2D图像和3D点云识别数据集中实现最先进的性能。代码是在https://github.com/albert0147/sfda_neighbors中获得的。

Ithaca is a Fuzzy Logic (FL) plugin for developing artificial intelligence systems within the Unity game engine. Its goal is to provide an intuitive and natural way to build advanced artificial intelligence systems, making the implementation of such a system faster and more affordable. The software is made up by a C\# framework and an Application Programming Interface (API) for writing inference systems, as well as a set of tools for graphic development and debugging. Additionally, a Fuzzy Control Language (FCL) parser is provided in order to import systems previously defined using this standard.

Data deprivation, or the lack of easily available and actionable information on the well-being of individuals, is a significant challenge for the developing world and an impediment to the design and operationalization of policies intended to alleviate poverty. In this paper we explore the suitability of data derived from OpenStreetMap to proxy for the location of two crucial public services: schools and health clinics. Thanks to the efforts of thousands of digital humanitarians, online mapping repositories such as OpenStreetMap contain millions of records on buildings and other structures, delineating both their location and often their use. Unfortunately much of this data is locked in complex, unstructured text rendering it seemingly unsuitable for classifying schools or clinics. We apply a scalable, unsupervised learning method to unlabeled OpenStreetMap building data to extract the location of schools and health clinics in ten countries in Africa. We find the topic modeling approach greatly improves performance versus reliance on structured keys alone. We validate our results by comparing schools and clinics identified by our OSM method versus those identified by the WHO, and describe OSM coverage gaps more broadly.

In this paper, we present an evolved version of the Situational Graphs, which jointly models in a single optimizable factor graph, a SLAM graph, as a set of robot keyframes, containing its associated measurements and robot poses, and a 3D scene graph, as a high-level representation of the environment that encodes its different geometric elements with semantic attributes and the relational information between those elements. Our proposed S-Graphs+ is a novel four-layered factor graph that includes: (1) a keyframes layer with robot pose estimates, (2) a walls layer representing wall surfaces, (3) a rooms layer encompassing sets of wall planes, and (4) a floors layer gathering the rooms within a given floor level. The above graph is optimized in real-time to obtain a robust and accurate estimate of the robot's pose and its map, simultaneously constructing and leveraging the high-level information of the environment. To extract such high-level information, we present novel room and floor segmentation algorithms utilizing the mapped wall planes and free-space clusters. We tested S-Graphs+ on multiple datasets including, simulations of distinct indoor environments, on real datasets captured over several construction sites and office environments, and on a real public dataset of indoor office environments. S-Graphs+ outperforms relevant baselines in the majority of the datasets while extending the robot situational awareness by a four-layered scene model. Moreover, we make the algorithm available as a docker file.

Algorithms that involve both forecasting and optimization are at the core of solutions to many difficult real-world problems, such as in supply chains (inventory optimization), traffic, and in the transition towards carbon-free energy generation in battery/load/production scheduling in sustainable energy systems. Typically, in these scenarios we want to solve an optimization problem that depends on unknown future values, which therefore need to be forecast. As both forecasting and optimization are difficult problems in their own right, relatively few research has been done in this area. This paper presents the findings of the ``IEEE-CIS Technical Challenge on Predict+Optimize for Renewable Energy Scheduling," held in 2021. We present a comparison and evaluation of the seven highest-ranked solutions in the competition, to provide researchers with a benchmark problem and to establish the state of the art for this benchmark, with the aim to foster and facilitate research in this area. The competition used data from the Monash Microgrid, as well as weather data and energy market data. It then focused on two main challenges: forecasting renewable energy production and demand, and obtaining an optimal schedule for the activities (lectures) and on-site batteries that lead to the lowest cost of energy. The most accurate forecasts were obtained by gradient-boosted tree and random forest models, and optimization was mostly performed using mixed integer linear and quadratic programming. The winning method predicted different scenarios and optimized over all scenarios jointly using a sample average approximation method.

The study aims the development of a wearable device to combat the onslaught of covid-19. Likewise, to enhance the regular face shield available in the market. Furthermore, to raise awareness of the health and safety protocols initiated by the government and its affiliates in the enforcement of social distancing with the integration of computer vision algorithms. The wearable device was composed of various hardware and software components such as a transparent polycarbonate face shield, microprocessor, sensors, camera, thin-film transistor on-screen display, jumper wires, power bank, and python programming language. The algorithm incorporated in the study was object detection under computer vision machine learning. The front camera with OpenCV technology determines the distance of a person in front of the user. Utilizing TensorFlow, the target object identifies and detects the image or live feed to get its bounding boxes. The focal length lens requires the determination of the distance from the camera to the target object. To get the focal length, multiply the pixel width by the known distance and divide it by the known width (Rosebrock, 2020). The deployment of unit testing ensures that the parameters are valid in terms of design and specifications.
