本文介绍了WiFi传感器 - 机器人（WSR）工具箱，一个开源C ++框架。它使团队中的机器人能够在彼此获得相对的轴承，即使在非思考（NLOS）设置中也是机器人中非常具有挑战性的问题。通过分析其传送的WiFi信号的阶段，因为机器人遍历环境来实现。基于我们的先前作品中开发的理论的这种能力是首次提供的作为OpenSource工具。它是由于缺乏使用机器人的本地资源（例如WiFi）来在NLOS中感测的易于部署的解决方案。这对多个机器人团队中的本地化，ad-hoc机器人网络和安全性有影响。工具箱专为使用商品硬件和车载传感器的机器人平台上分布式和在线部署而设计。我们还释放数据集，展示其在NLOS中的性能以及用于多机器人本地化USECASE的MOLICE中的表现。经验结果表明，我们的工具箱的轴承估计达到了5.10度的平均精度。在室内办公环境中的硬件部署中，这分别导致LOS和NLOS设置中的0.5米和0.9米的中值误差为0.5米和0.9米。

在本文中，我们推导了机器人来测量相对方向或到达角度（AOA）的新能力，以在非视线和未映射的环境中运行的其他机器人，而无需外部基础架构。我们通过捕获WiFi信号在从发送到接收机器人时遍历的所有路径来这样做，这是我们术语AOA简档。当机器人在3D空间中移动时，关键直觉是“在空中模拟空气中的天线阵列”，一种类似于合成孔径雷达（SAR）的方法。主要贡献包括i）一个框架，以适应任意3D轨迹的框架，以及所有机器人的持续移动性，而计算AOA配置文件和II）随附的分析，其提供了作为机器人轨迹的函数的AOA估计方差的较低限制基于Cramer Rao绑定的几何。这是一个关键的区别与先前的SAR的工作，限制机器人移动到规定的运动模式，不概括到3D空间，和/或在数据采集时段期间需要将机器人发送到静态。我们的方法导致更准确的AOA配置文件，从而更好地估计，并正式地将该观察表征为轨迹的信息性;我们推导出封闭形式的可计算量。所有理论发展都是通过广泛的模拟和硬件实验证实的。我们还表明，我们的配方可以与现成的轨迹估计传感器一起使用。最后，我们展示了我们系统对多机器人动态集合任务的表现。

This short report reviews the current state of the research and methodology on theoretical and practical aspects of Artificial Neural Networks (ANN). It was prepared to gather state-of-the-art knowledge needed to construct complex, hypercomplex and fuzzy neural networks. The report reflects the individual interests of the authors and, by now means, cannot be treated as a comprehensive review of the ANN discipline. Considering the fast development of this field, it is currently impossible to do a detailed review of a considerable number of pages. The report is an outcome of the Project 'The Strategic Research Partnership for the mathematical aspects of complex, hypercomplex and fuzzy neural networks' meeting at the University of Warmia and Mazury in Olsztyn, Poland, organized in September 2022.

Using robots in educational contexts has already shown to be beneficial for a student's learning and social behaviour. For levitating them to the next level of providing more effective and human-like tutoring, the ability to adapt to the user and to express proactivity is fundamental. By acting proactively, intelligent robotic tutors anticipate possible situations where problems for the student may arise and act in advance for preventing negative outcomes. Still, the decisions of when and how to behave proactively are open questions. Therefore, this paper deals with the investigation of how the student's cognitive-affective states can be used by a robotic tutor for triggering proactive tutoring dialogue. In doing so, it is aimed to improve the learning experience. For this reason, a concept learning task scenario was observed where a robotic assistant proactively helped when negative user states were detected. In a learning task, the user's states of frustration and confusion were deemed to have negative effects on the outcome of the task and were used to trigger proactive behaviour. In an empirical user study with 40 undergraduate and doctoral students, we studied whether the initiation of proactive behaviour after the detection of signs of confusion and frustration improves the student's concentration and trust in the agent. Additionally, we investigated which level of proactive dialogue is useful for promoting the student's concentration and trust. The results show that high proactive behaviour harms trust, especially when triggered during negative cognitive-affective states but contributes to keeping the student focused on the task when triggered in these states. Based on our study results, we further discuss future steps for improving the proactive assistance of robotic tutoring systems.

Sunquakes are seismic emissions visible on the solar surface, associated with some solar flares. Although discovered in 1998, they have only recently become a more commonly detected phenomenon. Despite the availability of several manual detection guidelines, to our knowledge, the astrophysical data produced for sunquakes is new to the field of Machine Learning. Detecting sunquakes is a daunting task for human operators and this work aims to ease and, if possible, to improve their detection. Thus, we introduce a dataset constructed from acoustic egression-power maps of solar active regions obtained for Solar Cycles 23 and 24 using the holography method. We then present a pedagogical approach to the application of machine learning representation methods for sunquake detection using AutoEncoders, Contrastive Learning, Object Detection and recurrent techniques, which we enhance by introducing several custom domain-specific data augmentation transformations. We address the main challenges of the automated sunquake detection task, namely the very high noise patterns in and outside the active region shadow and the extreme class imbalance given by the limited number of frames that present sunquake signatures. With our trained models, we find temporal and spatial locations of peculiar acoustic emission and qualitatively associate them to eruptive and high energy emission. While noting that these models are still in a prototype stage and there is much room for improvement in metrics and bias levels, we hypothesize that their agreement on example use cases has the potential to enable detection of weak solar acoustic manifestations.

Transfer learning on edge is challenging due to on-device limited resources. Existing work addresses this issue by training a subset of parameters or adding model patches. Developed with inference in mind, Inverted Residual Blocks (IRBs) split a convolutional layer into depthwise and pointwise convolutions, leading to more stacking layers, e.g., convolution, normalization, and activation layers. Though they are efficient for inference, IRBs require that additional activation maps are stored in memory for training weights for convolution layers and scales for normalization layers. As a result, their high memory cost prohibits training IRBs on resource-limited edge devices, and making them unsuitable in the context of transfer learning. To address this issue, we present MobileTL, a memory and computationally efficient on-device transfer learning method for models built with IRBs. MobileTL trains the shifts for internal normalization layers to avoid storing activation maps for the backward pass. Also, MobileTL approximates the backward computation of the activation layer (e.g., Hard-Swish and ReLU6) as a signed function which enables storing a binary mask instead of activation maps for the backward pass. MobileTL fine-tunes a few top blocks (close to output) rather than propagating the gradient through the whole network to reduce the computation cost. Our method reduces memory usage by 46% and 53% for MobileNetV2 and V3 IRBs, respectively. For MobileNetV3, we observe a 36% reduction in floating-point operations (FLOPs) when fine-tuning 5 blocks, while only incurring a 0.6% accuracy reduction on CIFAR10. Extensive experiments on multiple datasets demonstrate that our method is Pareto-optimal (best accuracy under given hardware constraints) compared to prior work in transfer learning for edge devices.

从随机实验获得的数据培训模型是做出良好决策的理想选择。但是，随机实验通常是耗时的，昂贵的，冒险的，不可行的或不道德的，决策者别无选择，只能依靠培训模型时在历史策略下收集的观察数据。这不仅为实践中的决策政策发挥了最佳作用，还为不同的数据收集协议对数据培训的各种政策的绩效的影响，或者在问题上的稳健性方面的稳健性，对问题的绩效提出了疑问诸如观察结果中的动作或奖励 - 特定延迟之类的特征。我们的目的是为了在LinkedIn优化销售渠道分配的问题回答此类问题，其中销售帐户（线索）需要分配给三个渠道之一，目的是在一段时间内最大程度地提高成功转换的数量。关键问题特征构成了观察分配结果的随机延迟，其分布既是通道和结果依赖性的。我们构建了一个离散的时间模拟，可以处理我们的问题功能并将其用于评估：a）基于历史规则的策略； b）有监督的机器学习政策（XGBOOST）； c）多臂强盗（MAB）策略，在涉及的不同情况下：i）用于培训的数据收集（观察性与随机分组）； ii）铅转换方案； iii）延迟分布。我们的仿真结果表明，Linucb是一种简单的mAB策略，始终优于其他策略，相对于基于规则的策略，实现了18-47％的提升

持续学习一系列任务是深度神经网络中的一个活跃领域。调查的主要挑战是灾难性遗忘或干扰以前任务的知识的现象。最近的工作调查了远期知识转移到新任务。向后转移以改善以前的任务中获得的知识的关注要少得多。通常，人们对知识转移如何有助于不断学习的任务有限。我们提出了一种在持续监督学习中进行知识转移的理论，该理论都考虑了前进和向后转移。我们旨在了解它们对越来越多知识的学习者的影响。我们得出这些转移机制中的每一种。这些界限对特定实现（例如深神经网络）是不可知的。我们证明，对于观察相关任务的持续学习者而言，前进和向后转移都可以随着观察到更多的任务而提高性能。

随着机器学习和系统社区努力通过自定义深度神经网络（DNN）加速器，多样的精度或量化水平以及模型压缩技术来实现更高的能源效率，因此需要设计空间探索框架，以结合量化意识的处理。在具有准确和快速的功率，性能和区域模型的同时，进入加速器设计空间。在这项工作中，我们提出了Quidam，这是一种高度参数化的量化量化DNN加速器和模型共探索框架。我们的框架可以促进对DNN加速器设计空间探索的未来研究，以提供各种设计选择，例如位精度，处理元素类型，处理元素的刮擦大小，全局缓冲区大小，总处理元素的数量和DNN配置。我们的结果表明，不同的精确度和处理元素类型会导致每个区域和能量性能方面的显着差异。具体而言，我们的框架标识了广泛的设计点，其中每个面积和能量的性能分别差异超过5倍和35倍。通过拟议的框架，我们表明，与最佳基于INT16的实施相比，轻巧的处理元素可在准确性结果上实现，每个区域的性能和能源改善高达5.7倍。最后，由于预先特征的功率，性能和区域模型的效率，Quidam可以将设计勘探过程加快3-4个数量级，因为它消除了每种设计的昂贵合成和表征的需求。
