双线性动力系统在许多不同的域中无处不在，也可以用于近似更通用的控制型系统。这激发了从系统状态和输入的单个轨迹中学习双线性系统的问题。在温和的边际均方稳定性假设下，我们确定需要多少数据来估算未知的双线性系统，直至具有高概率的所需精度。就轨迹长度，系统的维度和输入大小而言，我们的样本复杂性和统计错误率是最佳的。我们的证明技术依赖于Martingale小球条件的应用。这使我们能够正确捕获问题的属性，特别是我们的错误率不会随着不稳定性的增加而恶化。最后，我们表明数值实验与我们的理论结果良好。

学习如何有效地控制未知的动态系统对于智能自治系统至关重要。当潜在的动态随着时间的推移时，这项任务成为一个重大挑战。本文认为这一挑战，本文考虑了控制未知马尔可夫跳跃线性系统（MJS）的问题，以优化二次目标。通过采用基于模型的透视图，我们考虑对MJSS的识别自适应控制。我们首先为MJS提供系统识别算法，用于从系统状态，输入和模式的单个轨迹，从模式开关的演进中的底层中学习MJS的系统识别算法。通过混合时间参数，该算法的样本复杂性显示为$ \ mathcal {o}（1 / \ sqrt {t}）$。然后，我们提出了一种自适应控制方案，其与确定性等效控制一起执行系统识别，以使控制器以焦化方式调整。 Combining our sample complexity results with recent perturbation results for certainty equivalent control, we prove that when the episode lengths are appropriately chosen, the proposed adaptive control scheme achieves $\mathcal{O}(\sqrt{T})$ regret, which can be改进了$ \ mathcal {o}（polylog（t））$与系统的部分了解。我们的证据策略介绍了在MJSS中处理马尔可维亚跳跃的创新和较弱的稳定概念。我们的分析提供了影响学习准确性和控制性能的系统理论量的见解。提出了数值模拟，以进一步加强这些见解。

我们考虑由非线性状态等式$ H_ {T + 1} = \ phi（h_t，u_t; \ theta）+ w_t $ toy的稳定系统的问题问题。在这里$ \ theta $是未知的系统动态，$ h_t $是状态，$ u_t $是输入，$ w_t $是附加噪音矢量。我们研究了基于梯度的算法，以了解从单个有限轨迹所获得的样本的系统动态$ \ theta $。如果系统通过稳定输入策略运行，我们表明可以通过I.i.d近似时间依赖的样本。使用混合时间参数通过截断参数示例。然后，我们为经验损失梯度的均匀收敛性开发新的保证。与现有的工作不同，我们的界限是噪声敏感，允许高精度和小样本复杂度学习地面真实动态。我们的结果在一起，促进了稳定政策下的一般非线性系统的高效学习。我们专注于进入明智的非线性激活的保证，并在各种数值实验中验证我们的理论

Can a neural network estimate an object's dimension in the wild? In this paper, we propose a method and deep learning architecture to estimate the dimensions of a quadrilateral object of interest in videos using a monocular camera. The proposed technique does not use camera calibration or handcrafted geometric features; however, features are learned with the help of coefficients of a segmentation neural network during the training process. A real-time instance segmentation-based Deep Neural Network with a ResNet50 backbone is employed, giving the object's prototype mask and thus provides a region of interest to regress its dimensions. The instance segmentation network is trained to look at only the nearest object of interest. The regression is performed using an MLP head which looks only at the mask coefficients of the bounding box detector head and the prototype segmentation mask. We trained the system with three different random cameras achieving 22% MAPE for the test dataset for the dimension estimation

Effective management of public shared spaces such as car parking space, is one challenging transformational aspect for many cities, especially in the developing World. By leveraging sensing technologies, cloud computing, and Artificial Intelligence, Cities are increasingly being managed smartly. Smart Cities not only bring convenience to City dwellers, but also improve their quality of life as advocated for by United Nations in the 2030 Sustainable Development Goal on Sustainable Cities and Communities. Through integration of Internet of Things and Cloud Computing, this paper presents a successful proof-of-concept implementation of a framework for managing public car parking spaces. Reservation of parking slots is done through a cloud-hosted application, while access to and out of the parking slot is enabled through Radio Frequency Identification (RFID) technology which in real-time, accordingly triggers update of the parking slot availability in the cloud-hosted database. This framework could bring considerable convenience to City dwellers since motorists only have to drive to a parking space when sure of a vacant parking slot, an important stride towards realization of sustainable smart cities and communities.

Driving through pothole infested roads is a life hazard and economically costly. The experience is even worse for motorists using the pothole filled road for the first time. Pothole-filled road networks have been associated with severe traffic jam especially during peak times of the day. Besides not being fuel consumption friendly and being time wasting, traffic jams often lead to increased carbon emissions as well as noise pollution. Moreover, the risk of fatal accidents has also been strongly associated with potholes among other road network factors. Discovering potholes prior to using a particular road is therefore of significant importance. This work presents a successful demonstration of sensor-based pothole mapping agent that captures both the pothole's depth as well as its location coordinates, parameters that are then used to generate a pothole map for the agent's entire journey. The map can thus be shared with all motorists intending to use the same route.

In this paper, we present the Diver Interest via Pointing (DIP) algorithm, a highly modular method for conveying a diver's area of interest to an autonomous underwater vehicle (AUV) using pointing gestures for underwater human-robot collaborative tasks. DIP uses a single monocular camera and exploits human body pose, even with complete dive gear, to extract underwater human pointing gesture poses and their directions. By extracting 2D scene geometry based on the human body pose and density of salient feature points along the direction of pointing, using a low-level feature detector, the DIP algorithm is able to locate objects of interest as indicated by the diver.

We present the design, development, and evaluation of HREyes: biomimetic communication devices which use light to communicate information and, for the first time, gaze direction from AUVs to humans. First, we introduce two types of information displays using the HREye devices: active lucemes and ocular lucemes. Active lucemes communicate information explicitly through animations, while ocular lucemes communicate gaze direction implicitly by mimicking human eyes. We present a human study in which our system is compared to the use of an embedded digital display that explicitly communicates information to a diver by displaying text. Our results demonstrate accurate recognition of active lucemes for trained interactants, limited intuitive understanding of these lucemes for untrained interactants, and relatively accurate perception of gaze direction for all interactants. The results on active luceme recognition demonstrate more accurate recognition than previous light-based communication systems for AUVs (albeit with different phrase sets). Additionally, the ocular lucemes we introduce in this work represent the first method for communicating gaze direction from an AUV, a critical aspect of nonverbal communication used in collaborative work. With readily available hardware as well as open-source and easily re-configurable programming, HREyes can be easily integrated into any AUV with the physical space for the devices and used to communicate effectively with divers in any underwater environment with appropriate visibility.

许多水下任务，例如电缆和折磨检查，搜索和救援，受益于强大的人类机器人互动（HRI）功能。随着基于视觉的水下HRI方法的最新进展，即使在任务期间，自动驾驶水下车辆（AUV）也可以与他们的人类伴侣进行交流。但是，这些相互作用通常需要积极参与，尤其是人类（例如，在互动过程中必须继续看机器人）。因此，AUV必须知道何时开始与人类伴侣互动，即人是否关注AUV。在本文中，我们为AUV提供了一个潜水员的注意估计框架，以自主检测潜水员的注意力，然后（如果需要）在潜水员方面进行导航和重新定位以启动交互。该框架的核心要素是一个深神经网络（称为datt-net），它利用潜水员的10个面部关键点之间的几何关系来确定其头部方向。我们的基础实验评估（使用看不见的数据）表明，所提出的Datt-Net架构可以以有希望的准确性来确定人类潜水员的注意力。我们的现实世界实验还确认了Datt-NET的功效，该实验可以实时推理，并使AUV可以将自己定位为AUV-Diver相互作用。

在逻辑中使用元规则，即其内容包含其他规则的规则，最近在非单调推理的情况下引起了人们的关注：第一个逻辑形式化和有效算法来计算此类理论的（元）扩展在Olivieri等人（2021年）中提出的这项工作通过考虑悬浮方面扩展了这种逻辑框架。由此产生的逻辑不仅能够建模政策，还可以解决许多法律系统中发生的知名方面。已经研究了我们刚才提到的应用区域中使用不良逻辑（DL）对元符号建模的使用。在这一研究中，上述研究并不关注元符号的一般计算特性。这项研究以两个主要贡献填补了这一空白。首先，我们介绍并形式化了两种具有元符号的可性义能逻辑的变体，以代表（1）具有能态模态的可d不平式元理论，（2）规则之间的两种不同类型的冲突：简单的冲突可不诚实的无义冲突和谨慎的冲突，谨慎的冲突和谨慎的冲突可义的义逻辑。其次，我们推进有效算法以计算两个变体的扩展。
