A vital source of nutrition and a major contributor to the nation’s economic expansion is agriculture. Due to numerous complex factors such as environment, humidity, soil nutrients, and soil moisture, multi crop yield forecasting was very challenging. Because crop prediction is a complicated process, improving performance is challenging. To address these problems, an advance deep learning model was developed to predict crop types and its yields in a particular soil. A real time data were created, which contain various parameters such as soil nutrition’s, weather, data, seasons and temperature. The created dataset is pre-processed using outlier detection as well as normalization because it contains unwanted rows and columns. After that, the pre-processed data were given as input for the DeepNet230 model to analyze the input parameters like soil nutrition and temperature to predict the multi crop type and its yield quantity. DeepNet230 have the capacity of automatic feature learning and rapid unstructured process, so it provides an efficient prediction performance of crop yield and its types. The performance analysis of crop prediction for the proposed model are 93.7% accuracy, 93.4% recall, 92.8% precision and 92.9% specificity. Then, the performance of yield prediction for the identified crops are 95.5% accuracy, 91.6% recall, 93% precision and 94.2% specificity. In addition, the developed method was compared with several opposing methods for validation. The observed results show that the suggested method performed significantly better in real time due to its improved predictive capabilities.

摘要 农业是重要的营养来源,也是国家经济发展的主要贡献者。由于环境、湿度、土壤养分和土壤水分等众多复杂因素,多作物产量预测非常具有挑战性。由于作物预测是一个复杂的过程,因此提高预测性能具有挑战性。为了解决这些问题,我们开发了一种先进的深度学习模型,用于预测特定土壤中的作物类型及其产量。创建的实时数据包含各种参数,如土壤营养、天气、数据、季节和温度。创建的数据集使用离群点检测和归一化进行预处理,因为其中包含不需要的行和列。然后,将预处理后的数据作为 DeepNet230 模型的输入,以分析土壤营养和温度等输入参数,从而预测多种作物类型及其产量。DeepNet230 具有自动特征学习和快速非结构化处理的能力,因此能提供高效的作物产量及其类型预测性能。对所提出模型的作物预测性能分析结果为:准确率 93.7%、召回率 93.4%、精确率 92.8%、特异率 92.9%。对所识别作物的产量预测准确率为 95.5%,召回率为 91.6%,精确率为 93%,特异性为 94.2%。此外,还将所开发的方法与几种对立方法进行了比较验证。观察结果表明,由于建议的方法提高了预测能力,其实时性能明显更好。

Motor speech condition called dysarthria is caused by a lack of movement in the lips, tongue, vocal cords, and diaphragm are a few of the muscles needed to produce speech. Speech that is slurred, sluggish, or inaccurate might be the initial sign of dysarthria, which varies in severity. Parkinson’s disease, muscular dystrophy, multiple sclerosis, brain tumors, brain damage, and amyotrophic lateral sclerosis are among the health problems that can result from dysarthria. This research develops an efficient method for extracting features and classifying dysarthria affected persons from speech signals. This suggested method uses a speech signal as its source. The supplied speech signal is pre-processed to improve the identification of dysarthria speech. Pre-processing methods like the Butterworth band pass filter and Savitzky Golay digital FIR filter are used to smoothing the raw data. After pre-processing, the signals are input into the feature extraction techniques, such as Yule-Walker Autoregressive modelling, Mel frequency cepstral coefficients and Perceptual Linear Predictive to extract the important features. The dysarthria speech is finally detected using an improved Elman Spike Neural Network (EESNN) algorithm-based classifier. Hunter Prey Optimization (HPO) is used to select the weights of EESNN optimally. The proposed algorithm achieves 94.25% accuracy and 94.26% specificity values. Thus this proposed approach is the best choice for predicting dysarthria disease using speech signal.

摘要 构音障碍是由于嘴唇、舌头、声带和横膈膜等发音所需的肌肉缺乏运动而引起的运动性语言疾病。说话含糊不清、迟缓或不准确可能是构音障碍的最初征兆,其严重程度各不相同。帕金森病、肌肉萎缩症、多发性硬化症、脑肿瘤、脑损伤和肌萎缩侧索硬化症等都可能导致构音障碍。本研究开发了一种从语音信号中提取特征并对构音障碍患者进行分类的有效方法。该方法以语音信号为源。对提供的语音信号进行预处理,以提高对构音障碍语音的识别能力。预处理方法包括巴特沃斯带通滤波器和萨维茨基-戈莱数字 FIR 滤波器,用于平滑原始数据。预处理后,信号被输入特征提取技术,如 Yule-Walker 自回归模型、Mel 频率共振频率系数和感知线性预测,以提取重要特征。最后,使用基于改进型 Elman Spike 神经网络(EESNN)算法的分类器检测构音障碍语音。猎人猎物优化(HPO)用于优化选择 EESNN 的权重。所提出的算法达到了 94.25% 的准确率和 94.26% 的特异性。因此,该方法是利用语音信号预测构音障碍疾病的最佳选择。

In this paper proposes an algorithm for the analytical calculation of convolutional neural networks without using neural network training algorithms. A description of the algorithm is given, on the basis of which the weights and threshold values of a convolutional neural network are analytically calculated. In this case, to calculate the parameters of the convolutional neural network, only 10 selected samples were used from the MNIST digit database, each of which is an image of one of the recognizable classes of digits from 0 to 9, and was randomly selected from the MNIST digit database. As a result of the operation of this algorithm, the number of channels of the convolutional neural network layers is also determined analytically. Based on the proposed algorithm, a software module was implemented in the Builder environment C++, on the basis of which a number of experiments were carried out with recognition of the MNIST database. The results of the experiments described in the work showed that the computation time of convolutional neural networks is very short and amounts to fractions of a second or a minute. Analytically computed convolutional neural networks were tested on the MNIST digit database, consisting of 1000 images of handwritten digits. The experimental results showed that already using only 10 selected images from the MNIST database, analytically calculated convolutional neural networks are able to recognize more than half of the images of the MNIST database, without application of neural network training algorithms. In general, the study showed that artificial neural networks, and in particular convolutional neural networks, are capable of not only being trained by learning algorithms, but also recognizing images almost instantly, without the use of learning algorithms using preliminary analytical calculation of the values of the neural network’s weights.

摘要 本文提出了一种不使用神经网络训练算法的卷积神经网络分析计算算法。本文介绍了该算法,并在此基础上分析计算了卷积神经网络的权值和阈值。在本例中,为了计算卷积神经网络的参数,只使用了从 MNIST 数字数据库中选取的 10 个样本,每个样本都是从 MNIST 数字数据库中随机选取的 0 至 9 可识别数字类别之一的图像。由于该算法的运行,卷积神经网络层的通道数也是通过分析确定的。根据所提出的算法,在 C++ Builder 环境中实现了一个软件模块,并在此基础上对 MNIST 数据库进行了多次识别实验。实验结果表明,卷积神经网络的计算时间非常短,仅为几分之一秒或一分钟。分析计算的卷积神经网络在 MNIST 数字数据库中进行了测试,该数据库由 1000 幅手写数字图像组成。实验结果表明,仅使用从 MNIST 数据库中选出的 10 幅图像,分析计算卷积神经网络就能识别 MNIST 数据库中一半以上的图像,而无需使用神经网络训练算法。总之,研究表明,人工神经网络,特别是卷积神经网络,不仅能够通过学习算法进行训练,而且几乎能够在不使用学习算法的情况下通过初步分析计算神经网络的权重值立即识别图像。

Divergence Parametric Smoothing in Image Compression Algorithms 图像压缩算法中的发散参数平滑法

The paper elaborates on methods of digital image compression. The focus is on the compression method that represents a raster image as a set of multiply thinned sub-images. Sub-images are processed consecutively to generate special reference images. The difference between the synthesized reference image and original sub-image forms a divergence array. The algorithm introduces a discrete error into the divergence array to provide the actual bit-depth reduction. However, the introduction of the error inevitably impairs the quality of the decompressed image. The aim is to make sure that the parametric smoothing of divergence arrays can lessen this quality impairment without changing the bit depth reduction originally provided by the method. Numerical experiments on real digital images are carried out to prove that the use of parametric smoothing improves noticeably the efficiency of the image compression method under discussion.

摘要 本文阐述了数字图像压缩方法。重点是将光栅图像表示为一组多倍细化的子图像的压缩方法。子图像经过连续处理后生成特殊的参考图像。合成的参考图像与原始子图像之间的差值形成一个发散阵列。该算法将离散误差引入发散阵列,以提供实际的位深度缩减。然而,误差的引入不可避免地会损害解压缩图像的质量。我们的目标是确保对发散阵列进行参数化平滑处理能够在不改变该方法最初提供的比特深度缩减的情况下减轻这种质量损害。对真实数字图像进行的数值实验证明,使用参数平滑法可以明显提高所讨论的图像压缩方法的效率。

The clean hydrogen is needed for green energy. It can be obtained by the water electrolysis, which is energetically unprofitable. The problem of hydrogen storage solution made it possible to use it as an automobile fuel. There was a place for the laser in the cramped fuel cell. Previously, it was proposed to introduce laser radiation with the wavelengths corresponding to the water molecule vibrational levels excitation into the reaction zone to increase energy efficiency. In addition, all processes on the Earth should be considered taking into account hydrogen degassing, that is, the hydrogen escape from the Earth into the atmosphere. And so the laser is the most suitable tool for finding places where the hydrogen exits to the surface. In this paper, it is proposed to use the Raman lidar for laser remote sensing of the hydrogen molecules during its leaks into the atmosphere. Based on the results of the Raman lidar equation computer simulation in the range of ranging distances up to 100 m, it is shown that its parameters optimization will reduce the values of detectable concentrations of the hydrogen molecules in the atmosphere.

摘要 绿色能源需要清洁氢气。它可以通过水电解法获得,但这种方法在能源方面并不划算。解决了氢的储存问题,就有可能将其用作汽车燃料。激光在狭窄的燃料电池中占有一席之地。在此之前,曾有人提议将波长与水分子振动激发水平相对应的激光辐射引入反应区,以提高能量效率。此外,地球上的所有过程都应考虑到氢脱气,即氢从地球逃逸到大气中。因此,激光是寻找氢从地表逸出位置的最合适工具。本文建议使用拉曼激光雷达对氢分子泄漏到大气中的过程进行激光遥感。根据拉曼激光雷达方程计算机模拟在最远 100 米测距范围内的结果表明,其参数优化将降低大气中氢分子的可探测浓度值。

In Ethernet system, as a result of head of line blocking, numerous control data queues with high priority may cause priority queues to become overcrowded and their receiving DMAs (Direct Memory Access) to run out of buffer space, forcing them to delete packets that are still arriving from the network. Thus the primary goal of this work is to prevent deadlock in an Ethernet system while sending congested information across the Ethernet protocol and channel. In order to allow many processors to interact concurrently without causing a conflict, this research paper proposes a Memory crossbar switching control in which the memory is divided into global and local partitions utilizing the q-learning architecture in the development of a Q-Memory task routing architecture. The path average value therefore represents congestion information for each router and its surrounding nodes. The nearby router receives the path average value if the message is received. The networks-on-chip protocol and channel should be used to provide congestion information in order to prevent deadlock in a system and improve communication.

摘要 在以太网系统中,由于线路头部阻塞,众多具有高优先级的控制数据队列可能会导致优先级队列拥挤不堪,其接收 DMA(直接内存访问)的缓冲空间耗尽,迫使它们删除仍在从网络到达的数据包。因此,这项工作的主要目标是防止以太网系统出现死锁,同时通过以太网协议和通道发送拥挤的信息。为了让许多处理器同时交互而不造成冲突,本研究论文提出了一种内存跨条切换控制,在这种控制中,内存被分为全局和局部分区,在开发 Q-Memory 任务路由架构时利用了 q-learning 架构。因此,路径平均值代表了每个路由器及其周围节点的拥塞信息。如果收到信息,附近的路由器就会收到路径平均值。应利用片上网络协议和信道提供拥塞信息,以防止系统出现死锁并改善通信。

Air pollution imposed by particle matter (PM) made it a public health concern and hazard to humans and the environment. Reduced vision, allergic responses, pneumonia, asthma, cardiovascular disorders, lung cancer, and even mortality can result from prolonged exposure to the concentration of air’s small particulate matter. Air quality prediction can offer reliable information for future air pollution status to operate air pollution control effectively and make preventative plans. Tracking, predicting, and regulating emissions is crucial. Controlling PM2.5 is the key for enhancing air quality, and it can be accomplished by forecasting PM2.5 concentrations. This work develops a methodology for forecasting PM2.5 concentrations using a gradient-boosted regression tree with Convolutional Neural Network (CNN) and fuzzy K-nearest neighbour (fuzzy-KNN). The results of the proposed methodology have been comparatively analysed with multiple linear regression, stacked long short-term memory, bidirectional gated recurrent unit, and gradient-boosted regression tree. The Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) are evaluated, and it shows that the gradient-boosted regression tree model produces a reduced error with improved accuracy in forecasting air quality.

摘要 颗粒物质(PM)造成的空气污染已成为公共健康问题,并对人类和环境造成危害。长期暴露于空气中的小颗粒物浓度会导致视力下降、过敏反应、肺炎、哮喘、心血管疾病、肺癌,甚至死亡。空气质量预测可以为未来的空气污染状况提供可靠的信息,从而有效地进行空气污染控制和制定预防计划。跟踪、预测和控制排放至关重要。控制 PM2.5 是提高空气质量的关键,而这可以通过预测 PM2.5 的浓度来实现。本研究利用梯度提升回归树、卷积神经网络(CNN)和模糊 K 近邻(fuzzy-KNN),开发了一种预测 PM2.5 浓度的方法。建议方法的结果与多元线性回归、堆叠长短期记忆、双向门控递归单元和梯度增强回归树进行了比较分析。评估了均方根误差 (RMSE)、平均绝对误差 (MAE) 和平均绝对百分比误差 (MAPE),结果表明梯度增强回归树模型可减少误差,提高空气质量预报的准确性。

Most of the existing fake news identification models mainly focused on exploiting multi-modal features to enhanced performance recently. This paper proposes Multi-modal Co-Attention Capsules Network (MCCN) for fake news detection, which consists mainly of feature extraction layer, feature fusion layer and classification layer. Feature extraction layer achieves the features building of users’ profiles, multi-modal source news and comments. Feature fusion layer adopts a dual parallel Cross-Modal Co-Attentional to fuse multi-modal interactions between source news text and its attached image, Hierarchical Co-Attention to fuse the interactions among user information, source news content and comments. Classification layer adopts capsules network to realize false information identification. Experimental results on three widely used large-scale datasets show that MCCN can achieve the excellent performance by comparing with other baselines.

摘要 近年来,大多数现有的假新闻识别模型主要侧重于利用多模态特征来提高性能。本文提出了用于假新闻检测的多模态共注意力胶囊网络(MCCN),它主要由特征提取层、特征融合层和分类层组成。特征提取层实现了用户档案、多模态源新闻和评论的特征构建。特征融合层采用双并行交叉模态协同注意(Cross-Modal Co-Attentional)融合源新闻文本与所附图片之间的多模态交互,采用层次协同注意(Hierarchical Co-Attention)融合用户信息、源新闻内容和评论之间的交互。分类层采用胶囊网络实现虚假信息识别。在三个广泛使用的大规模数据集上的实验结果表明,与其他基线方法相比,MCCN 可以实现出色的性能。

Healthcare industry is a stage which is presented with tremendous innovative headways consistently. Parkinson disease (PD) has become a critical overall general clinical issue starting late. To provide the solution for this problem, in this paper, use fusion of machine learning and federated learning techniques for processing electronically collected patients’ health record (PD dataset) in accurate manner. The PD dataset are constantly gathered and sorted out to give a point by point history of patients, their sicknesses and determination plans. The medical PD dataset contains 43 400 electronic records of potential patients which includes normal, Ischemic and Hemorrhagic stroke. Cleaning, finding feature correlation and imputing missing values in the PD has to be performed by preprocessing & normalization approach. For further processing, using Random over sampling (ROS) methods the imbalanced PD dataset will be converted into balanced. From the balanced PD datasets the stroke prediction accuracy will be validated using Decision Tree, Logistic Regression, Random Forest and Improved LSTM (Imp-LSTM) machine learning algorithms. Using distinct experiments of executing performance measurements the accuracy rate from our prediction classifiers for the patient with smokes category will be 62.29, 71.36, 96.51 and 99.56% respectively as like the patient with never smoked category dataset the accuracy will be 70.49, 75.86, 96.49 and 99.58% respectively. The proposed Imp-LSTM algorithm in this research will effectively produce high overall accuracy in both the datasets, which means a successful decrease in the misdiagnosis rate for stroke prediction.

摘要医疗保健行业是一个不断取得巨大创新进展的领域。帕金森病(Parkinson disease,PD)已成为近年来临床上一个重要的综合性问题。为了解决这一问题,本文利用机器学习和联合学习的融合技术,对电子收集的患者健康记录(帕金森病数据集)进行精确处理。病历数据集不断被收集和整理,以逐点记录患者的病史、病情和决定计划。医疗 PD 数据集包含 43 400 份潜在患者的电子记录,其中包括正常、缺血性和出血性中风。必须通过预处理 & 归一化方法来清理、查找特征相关性和填补缺失值。为了进一步处理,将使用随机过度采样(ROS)方法把不平衡的卒中数据集转换为平衡的数据集。根据平衡的卒中数据集,将使用决策树、逻辑回归、随机森林和改进的 LSTM(Imp-LSTM)机器学习算法验证卒中预测的准确性。通过执行性能测量的不同实验,我们的预测分类器对吸烟患者类别的准确率分别为 62.29%、71.36%、96.51% 和 99.56%,对从不吸烟患者类别数据集的准确率分别为 70.49%、75.86%、96.49% 和 99.58%。本研究提出的 Imp-LSTM 算法在两个数据集中都能有效地产生较高的总体准确率,这意味着成功地降低了中风预测的误诊率。

Machine learning is currently one of the most actively developing research areas. Considerable attention in the ongoing research is paid to problems related to dynamical systems. One of the areas in which the application of machine learning technologies is being actively explored is aircraft of various types and purposes. This state of the art is due to the complexity and variety of tasks that are assigned to aircraft. The complicating factor in this case is incomplete and inaccurate knowledge of the properties of the object under study and the conditions in which it operates. In particular, a variety of abnormal situations may occur during flight, such as equipment failures and structural damage, which must be counteracted by reconfiguring the aircraft’s control system and controls. The aircraft control system must be able to operate effectively under these conditions by promptly changing the parameters and/or structure of the control laws used. Adaptive control methods allow to satisfy this requirement. One of the ways to synthesize control laws for dynamic systems, widely used nowadays, is LQR approach. A significant limitation of this approach is the lack of adaptability of the resulting control law, which prevents its use in conditions of incomplete and inaccurate knowledge of the properties of the control object and the environment in which it operates. To overcome this limitation, it was proposed to modify the standard variant of LQR (Linear Quadratic Regulator) based on approximate dynamic programming, a special case of which is the adaptive critic design (ACD) method. For the ACD-LQR combination, the problem of controlling the lateral motion of a maneuvering aircraft is solved. The results obtained demonstrate the promising potential of this approach to controlling the airplane motion under uncertainty conditions.

摘要 机器学习是当前发展最活跃的研究领域之一。正在进行的研究相当关注与动力系统有关的问题。正在积极探索机器学习技术应用的领域之一是各种类型和用途的飞机。这种技术现状是由于分配给飞机的任务复杂多样。在这种情况下,复杂的因素是对所研究对象的属性及其运行条件的了解不全面、不准确。特别是在飞行过程中可能会出现各种异常情况,如设备故障和结构损坏,必须通过重新配置飞机的控制系统和控制装置来应对。飞机控制系统必须能够通过及时改变所使用的控制法则的参数和/或结构,在这些情况下有效运行。自适应控制方法可以满足这一要求。目前广泛使用的动态系统控制法则合成方法之一是 LQR 方法。这种方法的一个重要局限是所产生的控制法则缺乏适应性,因此无法在对控制对象及其运行环境的属性了解不全面和不准确的情况下使用。为了克服这一局限性,有人建议在近似动态编程的基础上修改 LQR(线性二次调节器)的标准变体,其特例就是自适应批判设计(ACD)方法。针对 ACD-LQR 组合,解决了控制机动飞机横向运动的问题。结果表明,这种方法在不确定条件下控制飞机运动的潜力巨大。
