Metric embedding learning is a special form of supervised learning: instead of regression or classification a similarity value is predicted based on embedded vector distance. To implement such a behavior, first the Siamese architecture was introduced, where training is based on two input samples, and the transformation model seeks to minimize distance between same-category samples, and increase distance between different samples. To deal with the problem of overtraining, the triplet loss was introduced in 2015, considering three input samples at a training step. Triplet networks also highlighted a novel problem: sample selection is important to eliminate those training triplets, where the measured distance based similarity results in zero loss. To deal with this phenomena, triplet mining techniques are analyzed, while other researchers discussed the possibility of different triplet-based loss functions. In this paper, the so-called lossless triplet loss function is compared with the original triplet loss method, while applying different negative sampling methods.
度量嵌入学习是一种特殊形式的监督学习:不是回归或分类,而是基于嵌入向量距离预测相似值。为了实现这样的行为,首先引入了Siamese架构,其中训练基于两个输入样本,转换模型寻求最小化同类别样本之间的距离,并增加不同样本之间的距离。为了解决过度训练问题,2015年引入了三重损失,在一个训练步骤中考虑三个输入样本。三元组网络还突出了一个新问题:样本选择对于消除那些训练三元组很重要,其中测量的基于距离的相似性导致零损失。为了处理这种现象,分析了三重态挖掘技术,而其他研究人员讨论了不同的基于三重态的损失函数的可能性。本文将所谓无损三重态损失函数与原始三重态损失方法进行比较,同时采用不同的负采样方法。

Preliminary progress has been made in the assessment of unmanned aerial vehicle (UAV) swarm resilience based on complex networks. However, the evaluation results mostly use the initial performance state as the evaluation baseline, which is unreasonable. When UAV swarm performs a mission, as long as the network performance during the life cycle is sufficient to meet the mission requirements, it can be considered that UAV swarm has the resilience required to complete the mission. Therefore, a baseline assessment method of UAV swarm resilience based on complex networks is proposed in this paper. First, the baseline assessment method of UAV swarm resilience based on complex networks is characterized and investigated. Second, the effectiveness of the baseline assessment method is verified by simulation. The result shows that the baseline evaluation can effectively relax the evaluation result in a mission-oriented manner, and no longer use the initial state as the standard performance to measure the completion of the mission of UAV swarm. When UAV swarm performs a mission, it only needs to maintain or restore the resilience needed to complete the mission.
基于复杂网络的无人机群弹性评估取得了初步进展。然而,评价结果大多以初始性能状态作为评价基准,这是不合理的。当无人机群执行任务时,只要在生命周期内的网络性能足以满足任务要求,就可以认为无人机群具有完成任务所需的弹性。为此,本文提出了一种基于复杂网络的无人机群弹性基线评估方法。首先,研究了基于复杂网络的无人机群弹性基线评估方法。其次,通过仿真验证了基线评估方法的有效性。结果表明,基线评估能够以任务导向的方式有效放宽评估结果,不再以初始状态作为衡量无人机群任务完成情况的标准性能。当无人机群执行任务时,它只需要保持或恢复完成任务所需的弹性。

In various technical applications the local minimum of a differentiable cost function must be found under constraints that are interpreted as embedded hypersurfaces in the whole space of search. Generally Lagrange's “Reduced Gradient Method” can be applied for solving such problems in which the Lagrange multipliers associated with the individual constraint equations have important physical interpretation, therefore it is desirable to compute them. Though in special cases this algorithm can be replaced by closed form calculations via considering the “Auxiliary Function”, in other cases the algorithmic realization cannot be avoided. In this paper it is shown that via avoiding the calculation of the individual Lagrange multipliers the algorithm can be made considerably faster especially if the constraint equations are appropriately handled. Simulation investigations are presented to substantiate the suggested method.
在各种技术应用中,必须在整个搜索空间中被解释为嵌入超曲面的约束条件下找到可微代价函数的局部最小值。一般来说,拉格朗日“约简梯度法”可用于求解与个别约束方程相关的拉格朗日乘子具有重要物理解释的问题,因此需要计算拉格朗日乘子。虽然在特殊情况下可以通过考虑“辅助函数”将该算法替换为封闭形式计算,但在其他情况下无法避免算法的实现。本文表明,通过避免单个拉格朗日乘子的计算,特别是在适当处理约束方程的情况下,算法可以大大加快。仿真研究证实了所建议的方法。

The recent advance in artificial neural networks is an inspiration for automatic music generation. Deep learning algorithms help to produce pleasing melodies. They lead the creativity of musicians to be reproduced in digital environments. The proposed system learns from the Turkish popular music and then produces new music. In this study, our goal is to generate melody with a specific style, such as unforgettable soundtracks admired widely. We proposed a novel combination of convolutional neural network (CNN) and long short-term memory (LSTM) network for music generation. The experimental results reveal that the proposed combined deep model exhibits remarkable music quality compared to the lstm-only deep model or cnn-only deep model. We also conducted a survey to evaluate the quality of the generated music. The survey results show that the introduced model is capable of producing better quality and more pleasant music compared to other state-of-the-art music generation methods.

The aim of this paper is to create intelligent environment based on prototype platform, which is applicable in the area of the Internet of Things. Created intelligent environment allows to receive and send data in real time between the given setting and the user. Communication takes place between prototype platform Raspberry Pi created by us which communicates via script in Python and subsequently sends measured data to cloud service Firebase. Part of the intelligent environment consists of multiple sensors, which are used to control and collect data. Part of the implementation is also a web interface with the help of which the user can display the current measured values, which are visualized for better clarity. We can confirm that we do not need overpriced equipment to create appropriate intelligent environment and that we can substitute them with cheaper alternative, which this research proves.

The goal of this paper is to enhance RAPTOR journey planning algorithm to return a comprehensive list of journeys to the end user, offering a wide range of meaningful alternatives. We optimize for minimal length of the journeys, while considering the number of transfers. The RAPTOR journey planning algorithm optimizes for two criteria: arrival time and number of transfers. However, when optimizing for the minimal arrival time, RAPTOR doesn't maximize the departure time, neither it finds any later alternatives. Both properties are important for the end user satisfaction with a journey planner. Skipping in time to obtain the next alternative journey can degrade or significantly slow down the algorithm. In this paper we are analyzing model situations and impact of two approaches. Firstly, cycle management of general RAPTOR, and secondly, specific setting of RAPTOR's extension - rRAPTOR - which leads to provisioning set of journeys within a time range having minimal travel time for given number of transfers. The resulting journey planner is already used in public transit routing systems in the Czech Republic. We still receive customer complaints on the amount and variability of alternative journeys provided, however the complaint rate is steadily very low, around 1 complaint raised per quarter.
本文的目标是增强RAPTOR行程规划算法,为最终用户返回一个全面的行程列表,提供广泛的有意义的替代方案。我们在考虑换乘次数的同时,优化了最短的行程长度。RAPTOR的行程规划算法根据两个标准进行优化:到达时间和换乘次数。然而,当优化最小到达时间时,RAPTOR并没有最大化出发时间,也没有找到任何后续的替代方案。这两个属性对于最终用户对旅行规划师的满意度都很重要。在时间上跳过以获得下一个可选旅程可能会降低或显着减慢算法。本文分析了两种方法的模型情况和影响。首先,一般RAPTOR的周期管理,其次,RAPTOR扩展的特定设置- RAPTOR -它导致在给定数量的传输的最小旅行时间的时间范围内提供一组旅程。由此产生的旅程规划器已经在捷克共和国的公共交通路线系统中使用。我们仍然收到客户对提供的替代行程的数量和可变性的投诉,但是投诉率稳定地非常低,每个季度大约有1起投诉。

Mathematical models of tumor growth and the effect of therapy is fundamental for personalizing and optimizing anticancer therapies. The aim of the research is to provide a good estimation of personalized tumor model parameters based on measurements carried out on the patient. We use in silico experiments to create a large set of training data in a span that covers real-life scenarios. The data are used to train neural networks which provide a good initial guess for the model parameters. The estimated parameters can be used as initial estimations for more sophisticated, but local identification algorithms.

The types of noises present in this dataset are 1) Salt and pepper noise, caused by an error in transmission, analog-digital converter error, 2) The Landsat ETM + Scan Line Corrector (SLC)-of a problem, caused because of the poor performance of satellite sensors, cross-talk between sensors, etc. 3) Presence of thick clouds in its view due to poor atmospheric conditions. Usually, the remotely sensed data suffer an information loss because of satellite sensors' internal malfunction or poor atmospheric conditions such as thick clouds. Losing any pixel due to any external/internal error leads to a huge information loss in the images due to high spatial resolution and further tasks like detection, classification, segmentation, and many more to be applied to it. Therefore, it becomes an important task to regain the lost data before applying any other algorithm. This dataset contains a total of 21,080 images with a spatial resolution of 0.3m and 1.5m. The dataset is accessible at https://sites.google.com/view/clearviewdataset.
本文提出了第一个用于监督学习的数据集,用于重建遥感数据中的缺失数据。本数据集中存在的噪声类型有:1)盐和胡椒噪声,由传输错误、模数转换器错误引起;2)Landsat ETM +扫描线校正器(SLC)出现问题,由卫星传感器性能差、传感器之间的串扰等引起;3)由于大气条件差,在其视野中存在厚云。通常,由于卫星传感器内部故障或云层等恶劣的大气条件,遥感数据会出现信息丢失。由于高空间分辨率和进一步的任务,如检测、分类、分割等,由于任何外部/内部错误而丢失任何像素都会导致图像中巨大的信息损失。因此,在应用任何其他算法之前,恢复丢失的数据成为一项重要的任务。该数据集共包含21,080张图像,空间分辨率分别为0.3m和1.5m。该数据集可在https://sites.google.com/view/clearviewdataset上访问。
