Agriculture is the most important sector in Indian economy. India occupies the second highest rank in farm outputs in the world. Its contribution to the development of Indian economy has immense potential. So agriculture products may play vital role for economic growth. But the different kind of diseases in plant decreases the production of crops and growth rate of farmers. To identify and monitor the leaf diseases manually by farmers is very difficult. This is one of the reasons to develop an automatic leaf diseases detection model. The proposed model helps in automatic detection of different plant diseases at early stages. Thus, the production will increase in many folds. The main aim of this study is to identify different types of leaf diseases. Different feature extraction techniques have been used to enhance the classification accuracy. Support Vector Machine (SVM), Random Forest and Logistic Regression have been applied to classify different types of leaf diseases. When obtained results are compared SVM outperforms other two classifiers. Results show that, the model can be used in real life applications.
农业是印度经济中最重要的部门。印度的农业产量位居世界第二。它对印度经济发展的贡献潜力巨大。因此,农产品可能在经济增长中发挥至关重要的作用。但植物病害的种类繁多,降低了作物的产量和农民的生长速度。农民手工识别和监测叶片病害是非常困难的。这是开发叶片病害自动检测模型的原因之一。该模型有助于植物病害的早期自动检测。因此,产量将增加许多倍。本研究的主要目的是鉴定不同类型的叶片病害。不同的特征提取技术被用于提高分类精度。支持向量机(SVM)、随机森林(Random Forest)和逻辑回归(Logistic Regression)已被用于对不同类型的叶片病害进行分类。当得到的结果进行比较时,SVM优于其他两种分类器。结果表明,该模型可用于实际应用。

Solving an arithmetic problem is a complex task which involves fact retrieval, memory, sequencing and decision making. Automatic detection of such an activity from EEG signals will help in understanding of brain response to these cognitive tasks. In this work, we propose a mental arithmetic task detection algorithm from a single lead EEG signal. Fourier Decomposition method is used to decompose the signal into M uniform sub-bands and features, like energy, entropy, and variance, are computed from each of these sub-bands. Kruskal-Wallis method has been used to select only the statistically relevant features. These selected features are, then, used to classify the given EEG dataset into two classes using support vector machine with cubic kernel. To validate the efficacy of the proposed algorithm, simulation results are presented using dataset available on MIT PhysioNet, titled EEG during mental arithmetic task.
求解算术问题是一项复杂的任务,涉及事实检索、记忆、排序和决策。从脑电图信号中自动检测这种活动将有助于理解大脑对这些认知任务的反应。在这项工作中,我们提出了一种基于单导联脑电图信号的心算任务检测算法。采用傅里叶分解方法将信号分解为M个均匀的子带,并从每个子带中计算能量、熵和方差等特征。使用Kruskal-Wallis方法只选择统计相关的特征。然后,使用三次核支持向量机将给定的EEG数据集分为两类。为了验证该算法的有效性,利用MIT PhysioNet上的数据集“心算任务中的脑电图”给出了仿真结果。

This research work focuses on identifying a specific hand gesture from the given EMG signal, acquired by sensor-based band. Surface EMG and machine learning techniques are used for the identification and classification purpose. The raw EMG signal captured using the sensor is initially passed through suitable preprocessing steps to avoid the noise artifacts. Followed by this, 8 different time-domain features are collected from these raw EMG signals, using which a feature matrix is created. SVM and KNN are the machine learning classifiers used here. The entire system is implemented in MATLAB 2019a. Using these methods, a promising accuracy of 93% is obtained through KNN and an accuracy of 83% using SVM.

A Novel Area efficient and low power multiplexer based Data comparator for median filter in De-noising application is proposed. The proposed method uses multiplexer based implementation of borrow equation in a full subtractor which acts as a basic processing element of a Data Comparator. The proposed work was implemented in Microwind for three different Models of Mosfet and different technologies. The modifications in the existing borrow equation of a full subtractor using multiplexer only resulted in reduced number of transistors with reduced power. For an 8 bit image de-noising approach using median filter, which consists of a 8 bit data comparator will require only 116 transistors and dissipates 52.25uw of power for 90nm technology.

In this proposed method, Magnetic Resonance (MR) Brain image segmentation technique based on Pulse Coupled Neural Network (PCNN) clustering combined with Particle Swarm optimization (PSO) approach has been presented. Since, PCNN is robust to noise, the input image is added with 0.05 Level of impulsive noise and the segmented output was analysed based on the fractions, selectivity and sensitivity. Accuracy of the proposed technique was found to be 93%. Moreover, in this proposed method, instead of selecting the parameters of PCNN in a random manner, they are optimized using PSO technique.

Millimeter Wave (mmWave) and massive MIMO (Multiple Input Multiple Output) are promising solutions for 5G communications. Hybrid precoding architecture (analog and digital) is generally employed to resolve high hardware complexity and energy consumption issues. The current hybrid precoding architectures are computationally complex. This proposes a novel deep neural network based precoding architecture named ‘ComcepNet’. The network combines the features of Complex Convolution blocks and Inception Network. The network is observed to deliver superior performance in terms of accuracy and achievable datarate compared to the present Autoprecoder network.

Hybrid precoding architecture (analog and digital) is generally employed to resolve high hardware complexity and energy consumption issues. The current hybrid precoding architectures are computationally complex. This proposes a novel deep neural network based precoding architecture named ‘ComcepNet’. The network combines the features of Complex Convolution blocks and Inception Network. The network is observed to deliver superior performance in terms of accuracy and achievable datarate compared to the present Autoprecoder network.","PeriodicalId":321133,"journal":{"name":"2020 International Conference on Communication and Signal Processing (ICCSP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126377142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological signals from the human body play a significance role in monitoring health condition of person. Among these signals which are derived from heart are coined as Electrocardiogram (ECG). The ECG signals allow cardiologist physician to know about the condition of the heart such as stroke and arrhythmia. But the problem in existing ECG unit in hospital care unit have three to twelve electrodes system with the wet Ag/AgCl electrode which needs well trained person. The research objective is to develop and design self-monitoring ECG system with dual electrode from the finger site for people who are suffering from and have a history of a cardio abnormality at home or workplace. Since all biological signals have noise and low frequency so the acquired signal is passed through designed filter and amplifiers. Further acquired signal are display and analyzed interfacing with NI myDAQ and biomedical workbench. 20 subjects of age under 30year ECG signal are acquired using developed prototype and heart rate is calculated. The ECG signals from developed prototype are compared with conventional ECG unit and almost similar results are obtained. Hence, the developed prototype can be used for monitor cardiovascular disease status for people suffering from arrhythmia as well as the athletes and soldiers can benefit to keep track of their heart condition. The developed ECG system is economical and safe to use.
人体发出的生物信号在监测人体健康状况方面发挥着重要作用。这些由心脏发出的信号被称为心电图(Electrocardiogram, ECG)。心电信号可以让心脏科医生了解心脏的状况,如中风和心律失常。但目前医院监护病房的心电设备存在的问题是采用湿式Ag/AgCl电极的3 ~ 12电极系统,需要训练有素的人员。本研究的目的是为家庭或工作场所有心脏异常病史的人开发设计手指部位双电极自我监测心电系统。由于所有的生物信号都有噪声和低频,所以采集到的信号要经过设计好的滤波器和放大器。进一步采集的信号与NI myDAQ和生物医学工作台接口进行显示和分析。采用研制的样机采集20例30岁以下受试者的心电信号并计算心率。将所研制的样机的心电信号与传统的心电装置进行了比较,得到了几乎相同的结果。因此,所开发的样机可以用于监测心律失常患者的心血管疾病状态,也可以使运动员和士兵受益,跟踪他们的心脏状况。所研制的心电系统经济、安全。
