Energy Efficient Hardware Implementation of 2-D Convolution for Convolutional Neural Network 卷积神经网络二维卷积的节能硬件实现
S. K. Sharma, Anu Gupta, K. Raju
Over the last year, Deep neural networks (DNN) have been significantly accepted for computer vision applications because of high classification accuracy and versatility. Convolutional Neural Network (CNN) is one of the most popular architectures of DNN which is widely adopted for image, speech and video recognition. Extensive computation and large memory requirement of CNN s poses the bottleneck on its application. Field Programmable Gate Arrays (FPGAs) are considered to be suitable hardware platforms for deployment of CNNs with low power requirements. This paper focus on the design and implementation of hardware accelerator to perform the convolution product (matrix-matrix multiplication. We have used two optimization techniques to achieve energy efficiency. First, dataflow of the convolution phase is rescheduled to reduce the undesired on-chip memory accesses. Further, efficiency is enhanced by reducing the internal parallelism of structure as much as possible. Our architecture is implemented on the Xilinx ZCU104 evaluation board. The implemented design attains 98.1 GOPS/Joule and 32.77 GOPS/Joule for 8-bit and 16-bit data width respectively.
在过去的一年中,深度神经网络(DNN)因其高分类精度和多功能性而被广泛应用于计算机视觉应用。卷积神经网络(CNN)是深度神经网络中最流行的架构之一,广泛应用于图像、语音和视频识别。CNN的计算量大、内存需求大是其应用的瓶颈。现场可编程门阵列(fpga)被认为是部署低功耗cnn的合适硬件平台。本文重点研究了实现卷积积(矩阵-矩阵乘法)的硬件加速器的设计与实现。我们使用了两种优化技术来实现能源效率。首先,对卷积阶段的数据流进行重新调度,以减少不必要的片上存储器访问。此外,通过尽可能减少结构的内部平行度来提高效率。我们的架构是在赛灵思ZCU104评估板上实现的。实现的设计在8位和16位数据宽度下分别达到98.1 GOPS/焦耳和32.77 GOPS/焦耳。

Stock Market Prediction During COVID Using Stacked LSTM 基于堆叠LSTM的COVID期间股市预测
Ananya Singh, Swati Jain
In the field of computation, the art of predicting the stock market has always been a tough nut to crack for researchers. This is because stock prices are highly influential values. The prices depend on many factors, ranging from physical to physiological, rational and irrational, from geopolitical stability to the sentiments of the investors – all play a crucial role. Investors anticipate market conditions in the future for a successful investment. Hence considering the past stock prices as an embodiment of the factors mentioned above, we propose a stacked long-short-term-memory (LSTM) model to predict the closing index of stock prices during this highly uncertain pandemic period using root mean square error (RSME) as the performance indicator. The model is optimized to improve the prediction accuracy in order to achieve high performance stock forecasting. The dataset considered is from NIFTY 50 scaling across four sectors, namely – auto, bank, healthcare and metal from a duration of 30th January 2020 to 31st March 2022. This paper aims to consider the historical data to analyze future patterns and insights.
在计算领域,预测股票市场的艺术一直是研究人员难以攻克的难题。这是因为股价是极具影响力的价值。价格取决于许多因素,从生理因素到生理因素,从理性因素到非理性因素,从地缘政治稳定到投资者情绪,这些因素都起着至关重要的作用。投资者为成功投资而预测未来的市场状况。因此,考虑到过去的股票价格是上述因素的体现,我们提出了一个堆叠长短期记忆(LSTM)模型,以均方根误差(RSME)作为绩效指标来预测这一高度不确定的大流行期间的股票价格收盘指数。对模型进行了优化,提高了预测精度,实现了高效的股票预测。所考虑的数据集来自NIFTY 50在2020年1月30日至2022年3月31日期间跨越四个行业,即汽车、银行、医疗保健和金属。本文旨在考虑历史数据来分析未来的模式和见解。

Dynamic S-box with Reversible Gates for both Classical and Quantum Computer 经典和量子计算机的可逆门动态s盒
Anindita Sarkar, S. R. Chatterjee, M. Chakraborty
Reversible logic gates are universally adopted to replace the classical gates in various circuits to avail the advantages of power reduction and speed maximization. The application of reversible gates includes various fields like Quantum computing, Nano technology, low power CMOS, optical computing etc. Reversible gates are the key components for the quantum circuits. Here reversible gates are used to design a dynamic light weight S-box. The S-box is the key circuit component for cryptographic algorithm. The combination of Controlled NOT(CNOT), Peres and Selim Al Mamun (SAM) gates are used to achieve the dynamic nature of the S-Box. The simulation analysis is made to evaluate the cryptographic properties such as Avalanche Criteria (AC), Strict Avalanche Criteria (SAC), Bit Independence Criteria (BIC) and Nonlinearity to measure the strength and reliability of the proposed S-box. The comparative performance investigation is done with the Rijndael S-box used in popular AES algorithm as it was widely accepted by NISTIR and still shows that the proposed S-Box outperform with respect to the existing S-box. Use of input dependant reversible logic gate combination enhances the performance of the S-box in both classical and quantum computer.

Multiple Speech Mode Transformation using Adversarial Network 基于对抗网络的多语音模式转换
Kumud Tripathi, Jatin Kumar
The objective of Multiple Speech Mode Transformation (MSMT) is to transform speech from one form to another on the basis of their mode characteristics. In this work, we have explored three different modes of speech (conversation, extempore, and read modes) for their inter-conversion while preserving the speaker identity and the linguistic content. To accomplish this we used a variant of Star Generative Adversarial Network (StarGAN) named as StarGAN-VC. For training, our model does not require parallel occurrences of the sentences and with relatively lesser number of training example we were able to generate high quality transformed outputs. On conducting objective and subjective evaluations, it is deduced that the transformed speech mode outputs are highly comparable to the target speech mode.
多语音模式转换(MSMT)的目标是根据语音的模式特征将语音从一种形式转换为另一种形式。在这项工作中,我们探讨了三种不同的语言模式(对话、即兴和阅读模式)在保留说话者身份和语言内容的情况下的相互转换。为了实现这一点,我们使用了星生成对抗网络(StarGAN)的一个变体,名为StarGAN- vc。对于训练,我们的模型不需要句子的并行出现,并且使用相对较少的训练示例,我们能够生成高质量的转换输出。通过客观和主观评价,推导出转换后的语音模式输出与目标语音模式具有较高的可比性。

Extended Template Matching method for Region of Interest Extraction in Cephalometric Landmarks Annotation 基于扩展模板匹配的头颅特征点标注感兴趣区域提取方法
R. S, S. S, Rakshitha R, B. Poornima
Finding areas in the image where the subsequent processing of the features concentrates is known as Region of Interest (ROI) extraction. Utilizing ROI helps speed up processing by excluding irrelevant image regions. ROI extraction in biomedical landmark annotation problems is challenging as radiograph images have varying contrast and intensity levels. Cephalometric landmark annotation is a domain where ROI extraction plays a vital role in traditional machine learning and deep learning solutions. This work proposes a simple and feasible extension to the template matching method to extract the ROI from the cephalometric images. The exact ROI patch is located based on a combined metric calculated using the Normalized correlation coefficient measure and the distance measure. The algorithm is tested on publicly available cephalometric landmark annotation dataset. The experimental results show that the ROIs are extracted with an accuracy of 99.69%. Additionally, a reported average distance between the ROI patch center and the ground truth landmark is 3.96 mm. This demonstrates that the method can practically be used as an initial estimator, significantly improving the accuracy of landmark localization.

Modeling and Implementation of Grid Following and Grid Forming Inverters 网格跟踪和网格形成逆变器的建模与实现
Pallavi Rani, Shikhar, S. Murugesan, A. K. Singh
An efficient way to lessen the burden on the grid is by deploying micro-grids to offer local power to consumers. The issues associated by such micro-grids are power quality, load sharing, synchronization and operating the distributed generators in grid forming and grid following converters. In this work, modelling and implementation of grid following mode and grid forming mode of converters along with the phase locked loop, filter and controller are done. This paper presents an approach for controlling the power between DC source and utility grid, and vice verse. In both the type of modes, the modeled approach provides accurate active power, reactive power, phase angle, frequency, voltage and current waveform. The motive of this work is to explain the two operating modes of the inverter in a lucid manner for the researchers. This modeling is essential for the researchers to easily understand about the grid following and grid forming operating mode of the converters. A grid-connected inverter for distributed generation is modeled and it is presented in a simpler fashion so that the researcher can understand and implement both the fundamental idea behind the grid-connected inverter's component parts and how they work together as an unit. Both grid-forming and grid-following modes of operation are modelled and implemented in MATLAB R2021a.

A grid-connected inverter for distributed generation is modeled and it is presented in a simpler fashion so that the researcher can understand and implement both the fundamental idea behind the grid-connected inverter's component parts and how they work together as an unit. Both grid-forming and grid-following modes of operation are modelled and implemented in MATLAB R2021a.","PeriodicalId":185782,"journal":{"name":"2022 IEEE 9th Uttar Pradesh Section International Conference on Electrical, Electronics and Computer Engineering (UPCON)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115125431","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}

Smart agriculture or digital farming systems is a part of urban farming. It is known for their qualitative and quantitative cultivation of different varieties of crops to be grown in the farm or household gardens or kitchen gardens. Under the Internet of Things (IoT), other technologies are involved in the urban farming process include solar panels, soil moisture sensor technology, temperature sensing technology, automation, and irrigation systems. The application of smart agriculture using IoT tools can help us monitor and automate the process which requires regular monitoring. The smart urban farming process helped us to experiment with sensors like soil, temperature (at distinct temperatures), climate, and availability of moisture in the soil. After monitoring the parameters that affect the development of crops, we can provide crops the most suitable condition to grow in.
智能农业或数字农业系统是城市农业的一部分。它以在农场或家庭花园或厨房花园中种植不同品种的作物的定性和定量栽培而闻名。在物联网(IoT)下,城市农业过程中涉及的其他技术包括太阳能电池板、土壤湿度传感器技术、温度传感技术、自动化和灌溉系统。使用物联网工具的智能农业应用可以帮助我们监控和自动化需要定期监控的过程。智能城市农业过程帮助我们对土壤、温度(在不同温度下)、气候和土壤中水分的可用性等传感器进行实验。通过对影响作物生长发育的参数进行监测,为作物提供最适宜的生长条件。
