The Iowa Gambling Task (IGT) has become the classical experiment with many studies of cognitive decision models. In this work, we explore whether Autoregressive Integrated Moving Average (ARIMA) models and Recurrent Neural Networks (RNN) in time series analysis can be applied to extract the decision features of IGT participants. The simulation results of IGT show that both models can capture the selection characteristics of participants and make subsequent selection prediction accordingly. Furthermore, the RNN containing selection features with different preferences can represent the corresponding participants to participate in the IGT experiment.
爱荷华赌博任务(Iowa Gambling Task, IGT)已成为众多认知决策模型研究的经典实验。在这项工作中,我们探讨了时间序列分析中的自回归综合移动平均(ARIMA)模型和递归神经网络(RNN)是否可以应用于提取IGT参与者的决策特征。IGT的仿真结果表明,两种模型都能捕捉到参与者的选择特征,并据此进行后续的选择预测。此外,包含不同偏好选择特征的RNN可以代表相应的参与者参与IGT实验。

Pneumonia is a lung infection caused by bacteria, viruses, or fungi. It is one of the deadliest lung diseases among children under the age of five. An expert or radiologist can usually diagnose the condition using X-ray images of the chest. The use of machine learning in medical image processing helps to improve detection accuracy. This study aims to develop and present a combined Deep Learning model for classifying patients with Pneumonia disease based on chest X-rays. Three separate models are trained for the chest X-ray dataset in the proposed implementation, the first of which is the custom Convolutional Neural Network model. The other two models are Xception and EfficientNetB4. Various data augmentation and pre-processing methods are used, along with hyperparameter tuning. A combined model is created by assigning weights to the trained models based on their recall and accuracy values, and the classification results are obtained by a polling mechanism at the output, which gives an accuracy of 98.00%. The proposed work outperforms the existing literature in terms of several performance parameters.

In this article, we have investigated the Gate misalignment effects on the performance of the Double gate hetero dielectric TFET(DGH-TFET) biosensor device in terms of subthreshold swing(SS), ON-current (I$_{mathbf{on}}$), OFF Current (I$_{mathbf{off}}$), Threshold voltage (Vth) and the ratio of ON-current (Ion) to the OF-current (I$_{mathbf{on}} {/mathbf{I}}_{mathbf{off}}$). For the first time, we have thoroughly investigated the misalignment of gate electrodes effect on the sensitivity of the double gate TFET based biosensor where actually considered the symmetric gate structure with no deviation in the gate alignment, however practically which is not possible. With due respect to the investigation carried in this work along with the sensitivity analysis, it observed that position and the alignment of both top and bottom gate show significant impact on the sensitivity of the biosensor. The misalignment of the double gate is executed by altering the position of the top gate in overlapped state and underlapped state concerning the bottom gate of the proposed double gate TFET biosensor. The underlapped gate structure degrades the performance device compared to the symmetric aligned gate structure, but the overlapped gate structure improves the device’s overall performance. The investigation is carried by taking the misalignment effect in the range of 10 nm in both overlapped and underlapped cases. The underlapped alignment gate structure falls of the subthreshold sensitivity by 30%, where the overlapped gate structure become the advantage for shoot up the sensitivity of the doublet gate hetero dielectric TFET biosensor by 25% and the underlapped gate structure improves the threshold voltage sensitivity 45% on an average.
在本文中,我们从亚阈值摆幅(SS)、通流(I$_{mathbf{on}}$)、关流(I$_{mathbf{OFF}}$)、阈值电压(Vth)和通流(Ion)与通流(Ion)之比(I$_{mathbf{on}}} {/mathbf{I}} {mathbf{OFF}}}$)等方面研究了栅极错位对双栅异质介质TFET(DGH-TFET)生物传感器器件性能的影响。本文首次深入研究了栅极电极错位对基于双栅极TFET的生物传感器灵敏度的影响,其中实际考虑了栅极排列无偏差的对称栅极结构,但实际上这是不可能的。考虑到在这项工作中进行的调查以及灵敏度分析,它观察到顶部和底部栅极的位置和对齐对生物传感器的灵敏度有重大影响。通过改变双栅TFET生物传感器的顶栅在重叠状态和欠重叠状态下的位置来实现双栅的错位。与对称排列栅极结构相比,重叠栅极结构降低了器件的性能,但重叠栅极结构提高了器件的整体性能。在重叠和不重叠的情况下,采用10 nm范围内的不对准效应进行了研究。叠合排列栅极结构使双栅极异质介质TFET生物传感器的亚阈值灵敏度降低了30%,其中叠合排列栅极结构使其灵敏度提高了25%,叠合排列栅极结构使阈值电压灵敏度平均提高了45%。

In this paper we propose an Artificial Neural Network (ANN) based approach to reduce the computational complexity on solving the combinatorial optimization problem of resource allocation in a downlink multicarrier non-orthogonal multiple access (MC-NOMA) network aided by coordinated direct and relay transmission (CDRT) in the presence of underlay cognitive radio (CR) users. The combinatorial optimization involves optimal user pairing, relay selection, subcarrier pairing and assignment which, when solved by exhaustive search, incurs a high computational complexity and processing delay. We show that an ANN trained by stochastic gradient descent (SGD) based supervised learning algorithm can do the same with low complexity and can provide more than 50% reduction in processing delay.

Change Detection of SAR images based on Convolution Neural Network with Curvelet Transform 基于曲率变换卷积神经网络的SAR图像变化检测

Change detection is an essential task to study the changes of earth surfaces in remote sensing. It is extensively being investigated in SAR images nowadays. However, SAR images suffer from the speckle noise, which is a major drawback. To address the speckle noise problem, we propose the convolutional neural network with curvelet transform. As curvelet transform can suppress the noise, it is applied in preclassification, where the difference image is transformed using curvelet. Further, transformed image is classified by hierarchical fuzzy c-means (FCM) clustering, where each pixel is classified into different classes like changed class and unchanged class. From the preclassification, patches centered at the pixels belonging to these classes are generated as the training samples. Moreover, these training samples are passed through median filter before sending them to the convolutional neural network (CNN). The median filter helps in the reduction of noise. After the training of the CNN model, the trained model classifies the image pixels and provides the final binary change map. The experimental results obtained from the two SAR datasets confirm the effectiveness of the proposed method.
变化探测是遥感研究地表变化的一项重要任务。目前在SAR图像中对其进行了广泛的研究。然而,SAR图像受到斑点噪声的影响,这是一个主要的缺点。为了解决散斑噪声问题,我们提出了基于曲波变换的卷积神经网络。由于曲波变换可以抑制噪声,因此将其应用于预分类中,对差分图像进行曲波变换。然后,对变换后的图像进行分层模糊c均值(FCM)聚类,将每个像素点分为变化类和不变类。从预分类中,生成以属于这些类的像素为中心的patch作为训练样本。此外,这些训练样本在发送到卷积神经网络(CNN)之前经过中值滤波。中值滤波器有助于降低噪声。CNN模型经过训练后,训练后的模型对图像像素进行分类,并提供最终的二值变化图。两个SAR数据集的实验结果验证了该方法的有效性。

As curvelet transform can suppress the noise, it is applied in preclassification, where the difference image is transformed using curvelet. Further, transformed image is classified by hierarchical fuzzy c-means (FCM) clustering, where each pixel is classified into different classes like changed class and unchanged class. From the preclassification, patches centered at the pixels belonging to these classes are generated as the training samples. Moreover, these training samples are passed through median filter before sending them to the convolutional neural network (CNN). The median filter helps in the reduction of noise. After the training of the CNN model, the trained model classifies the image pixels and provides the final binary change map. The experimental results obtained from the two SAR datasets confirm the effectiveness of the proposed method.","PeriodicalId":6793,"journal":{"name":"2022 2nd International Conference on Artificial Intelligence and Signal Processing (AISP)","volume":"172 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79527360","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}

RADAR (Radio Detection and Ranging) is an electromagnetic device used for detecting and locating objects from their reoccurrence signals. The received signal is then dealt with for information abstraction, like., target detection besides the velocity of the target. In CW radars the frequency measurement is done by de-modulating the received signal with respect to a transmitting. The matching velocity can be anticipated by passing the Doppler spectra through a filter bank. Finding the frequency in a pulse radar system is difficult than in CW radar. Thus, a better approach is the Doppler Processing state machine. The received signal is processed for required information. Detection is done by an algorithm called CFAR (Constant False Alarm Rate). In CFAR, a certain power threshold is determined. If the threshold is too high, then fewer targets are detected and conversely, if the threshold is too low then the false detection rate will increase. This threshold-based algorithm detects false targets in addition to original ones and to overcome this, a method called Cell Averaging Constant False Alarm Rate (CACFAR) would be used. Another parameter velocity is determined by Doppler frequency. The architecture is implemented in MATLAB/SIMULINK using Xilinx System Generator. To implement this model, three processing modules are required. Upon successful simulation, respective Verilog HDL code is generated and that code is run to observe design constraints like area, power, and delay. For CA-CFAR module at 2.5GHz frequency, the On-Chip power is 8.763W. At 0.95V, low On-chip power of 3.932W was observed at the frequency of 4GHz.
雷达(Radio Detection and Ranging,简称RADAR)是一种电磁装置,用于根据物体的再出现信号对其进行探测和定位。然后对接收到的信号进行信息抽象处理,如。,目标检测,除了目标的速度。在连续波雷达中,频率测量是通过相对于发射信号对接收信号进行解调来完成的。通过多普勒谱通过滤波器组可以预测匹配速度。在脉冲雷达系统中,频率的确定比在连续波雷达系统中困难。因此,更好的方法是多普勒处理状态机。对接收到的信号进行处理以获取所需的信息。检测是由一种叫做CFAR(恒定虚警率)的算法完成的。在CFAR中,确定了一定的功率阈值。如果阈值过高,则检测到的目标较少,反之,如果阈值过低,则误检率会增加。这种基于阈值的算法除了检测原始目标外还检测假目标,为了克服这一点,将使用一种称为单元平均恒定虚警率(CACFAR)的方法。另一个参数速度是由多普勒频率决定的。该体系结构在MATLAB/SIMULINK中使用Xilinx System Generator实现。要实现这个模型,需要三个处理模块。仿真成功后,生成相应的Verilog HDL代码,并运行该代码以观察设计约束,如面积,功率和延迟。对于频率为2.5GHz的CA-CFAR模块,片上功率为8.763W。在0.95V时,在4GHz频率下观察到3.932W的低片上功率。

The rapid growth in computational density and better computing, as well as the rise of worldwide knowledge transfer, have driven significant technological progress in the field of Biotechnology over the past few years. This is one of the primary technological advances expected to further transform this industry into low-cost single-board computers. So far, there hasn’t been a comprehensive analysis of the current adoption of these devices, as well as a general guide to assist researchers in incorporating them into their study. This study focuses on Raspberry Pi applicability in disciplines such as biotechnology, biosensors, bioprinters, biological, biosignal, bioaerosol, bioengineering, biochemical, biometrics and bioreactor. Since its initial introduction in 2012, the Raspberry Pi has gained popularity among a wide range of disciplines, as well as biologists in the lab, field and classrooms. A wide range of applications are available, from basic solutions such as nest box monitoring, wildlife camera capture, high-throughput behavioral recording, large-scale plant phenotyping, underwater video surveillance, closed-loop operant, to customized custom-built devices such as autonomous ecosystem monitoring. Despite the diversity of its applications, the Raspberry Pi has received only limited attention from the scientific community.
