Rapid advancements in image and video processing technologies are poised to create remarkable impacts on a wide range of industries. A significant challenge in these processing technologies resides in identifying the features fed for image classification algorithms. Though all classification algorithms could identify, extract and classify the features of a given image, their accuracy is directly proportional to the number of sample points taken from the image using a sampling technique. As the accuracy improves with a substantial number of sample points, the time consumed to process them looms large. These challenges beseech enormous computing power. Quantum computers avowed exceptional computing power is expected to bridge the growing demands. To address these challenges effectively, we have chosen a specific problem, Facial Expression Analysis, to explore in-depth and arrive at a purposeful approach to deliver the desired outcome. The purpose of this paper is two-pronged. Perform a comparative study of accuracy and performance of classical and quantum image processing algorithms in classical and quantum computers, respectively. Secondly, devise a novel hybrid model using a quantum distance-based classifier augmented with a classical linear support vector machine to overcome the limitations observed. Sample image features derived from the quantum classifier were used to train the linear classifier. The results were observed to be better relative to results from the classical distance-based classifier. Holistically, the novel hybrid model is observed as a promising solution for all image classification problems. Our future work will focus on sophisticated usage of a linear classification algorithm in quantum computing.
图像和视频处理技术的快速发展将对广泛的行业产生显著的影响。这些处理技术的一个重大挑战在于识别为图像分类算法提供的特征。尽管所有的分类算法都可以识别、提取和分类给定图像的特征,但它们的精度与使用采样技术从图像中提取的样本点数量成正比。随着样本点数量的增加,精度得到提高,处理它们所消耗的时间也随之增加。这些挑战需要巨大的计算能力。量子计算机宣称其卓越的计算能力有望满足日益增长的需求。为了有效地应对这些挑战,我们选择了一个特定的问题——面部表情分析,来深入探索,并得出一个有目的的方法来实现预期的结果。本文的目的有两个方面。分别在经典计算机和量子计算机上对经典和量子图像处理算法的精度和性能进行比较研究。其次,利用基于量子距离的分类器与经典线性支持向量机的增强,设计了一种新的混合模型,以克服所观察到的局限性。利用量子分类器得到的样本图像特征来训练线性分类器。结果被观察到相对于经典的基于距离的分类器的结果更好。总的来说,这种新的混合模型被认为是解决所有图像分类问题的一种很有前途的方法。我们未来的工作将集中在量子计算中线性分类算法的复杂使用上。

With the increase in the number of vehicles on the road, traffic congestion has become a major problem in metropolitan areas. Generally, the traffic flow through a junction is controlled using static traffic lights which are unable to adapt to the real-time traffic condition at a junction and do not prioritize the movement of certain types of vehicles. Emergency vehicles (e.g. ambulance, fire, police, etc.) play a crucial role in all life-threatening situations, and ensuring their movement through a congested junction with minimal time delay is essential.In this paper, we propose an adaptive and efficient traffic signal control system for less-lane disciplined heterogeneous (mixed) traffic that can be easily integrated with the existing static traffic lights in a resource-constrained environment. A sound sensor-based emergency vehicle detection system is designed that accurately detects and classifies emergency vehicles by identifying their unique siren sound. The traffic camera data are processed in real-time to compute the PCU counts at every approach of a junction and to detect emergency vehicles that do not generate siren sounds. The experiment results show 100% accuracy in emergency vehicle detection, more than 95% accuracy in the emergency vehicle classification, and 65% accuracy in vehicle classification and PCU count. We also design a queuing theory-based cost function that considers the prevailing traffic condition and the presence of priority vehicle(s) at a junction. The cost function can be used to adapt the green phase of different approaches at a junction to improve the vehicle flow through the junction while minimizing the delay for the emergency vehicles.
随着道路上车辆数量的增加,交通拥堵已成为大都市地区的一个主要问题。一般情况下,通过路口的交通流量是由静态交通灯控制的,它不能适应路口的实时交通状况,也不能优先考虑某些类型的车辆的移动。紧急车辆(如救护车、消防车、警车等)在所有危及生命的情况下都发挥着至关重要的作用,确保它们在最短时间内通过拥挤的交叉路口是至关重要的。在本文中,我们提出了一种自适应和高效的交通信号控制系统,用于较少车道的异构(混合)交通,该系统可以在资源受限的环境中轻松地与现有的静态交通信号灯集成。设计了一种基于声音传感器的应急车辆检测系统,通过识别应急车辆独特的警报器声音,对应急车辆进行准确的检测和分类。交通摄像头的数据被实时处理,以计算每个路口的PCU计数,并检测没有发出警报器声音的紧急车辆。实验结果表明,该方法对应急车辆检测的准确率达到100%,对应急车辆分类的准确率达到95%以上,对车辆分类和PCU计数的准确率达到65%以上。我们还设计了一个基于排队理论的成本函数,该函数考虑了当前的交通状况和路口优先车辆的存在。成本函数可用于调整交叉口不同路径的绿灯相位,以改善交叉口的车流,同时最大限度地减少应急车辆的延误。

Learning Semantic Representations and Discriminative Features in Unsupervised Domain Adaptation 无监督域自适应中语义表征和判别特征的学习

In domain adaptation, the goal is to train a neural network on the source domain and obtain a good accuracy on the target domain. In such a scenario, it is important to transfer the knowledge from the labelled source domain to the unlabelled target domain due to the expensive cost of manual labelling. Following the trail of works in the recent time, feature level alignment seems to be the most promising direction in unsupervised domain adaptation. In most of the recent works using this feature alignment, the semantic information present in the labelled source domain has not been exploited. Among the works that have tried to learn this semantic representations, the discriminative features have not been taken into consideration which results in lower accuracy on target domain. In this paper, we present a novel approach, joint discriminative and semantic transfer network (JDSTN) that not only aligns the semantic representations of source and target domain, but also enhances the discriminative features and thereby improving the accuracy significantly. This is achieved by using pseudo-labels to align the feature centroids of source and target domains while introducing losses that promote the learning of discriminative features.
在域自适应中,目标是在源域训练神经网络,在目标域获得较好的精度。在这种情况下,由于手工标记的成本昂贵,将知识从标记的源领域转移到未标记的目标领域是很重要的。从近年来的工作轨迹来看,特征级对齐似乎是无监督域自适应中最有前途的方向。在最近使用这种特征对齐的大多数工作中,标记源域中存在的语义信息尚未被利用。在尝试学习这种语义表示的工作中,没有考虑到区别特征,导致目标域上的准确率较低。在本文中,我们提出了一种新的方法——联合判别和语义转移网络(JDSTN),该方法不仅对齐了源域和目标域的语义表示,而且增强了判别特征,从而显著提高了准确率。这是通过使用伪标签来对齐源域和目标域的特征质心,同时引入促进判别特征学习的损失来实现的。

Convolutional Neural Networks (CNNs) handle a massive variety of datasets with great accuracy for various image processing and computer vision applications. However, it comes at the cost of the requirement of large hardware resources, which are computational and energy extensive. There is a need for efficient hardware and algorithmic optimization for real-time CNN inference while deploying the CNN model. This paper proposes a novel VLSI architecture of generalized pooling operation for hardware acceleration of CNN inference in real-time. Generalized pooling operation adaptively downsamples the huge parameter set generated by the convolutional layer by generating weights as per the input features. It is capable of accommodating varying feature maps and preserves significant features, unlike other counterparts maximum and average pooling. In order to efficiently compute the output of the generalised pooling operation, the proposed hardware design makes use of the Newton-Raphson reciprocal approximation for division operations, a low number of comparators, and a high degree of parallelism. The proposed architecture is developed and tested for performance evaluation on Xilinx Vivado 2018.3, and the target device chosen is Zynq UltraScale + MPSoC ZCU104 Evaluation board.
卷积神经网络(cnn)以极高的精度处理各种图像处理和计算机视觉应用的大量数据集。然而,它的代价是需要大量的硬件资源,这些资源需要大量的计算和能源。在部署CNN模型时,需要对实时CNN推理进行有效的硬件和算法优化。本文提出了一种基于广义池化运算的VLSI架构,用于CNN推理的实时硬件加速。广义池化操作根据输入特征生成权值,自适应地对卷积层生成的庞大参数集进行下采样。它能够适应不同的特征映射,并保留重要的特征,不像其他对等的最大和平均池化。为了有效地计算广义池化操作的输出,所提出的硬件设计利用牛顿-拉夫森互反近似进行除法操作,较少的比较器数量和高度的并行性。在Xilinx Vivado 2018.3平台上开发并测试了所提出的架构,并选择了Zynq UltraScale + MPSoC ZCU104评估板作为目标器件。

Dynamic ocean current in real-time plays a significant role for the precise navigation of underwater vehicles. Estimation and prediction of ocean currents with traditional methods such as Navier–Stokes equations, which are computationally very complex and also need huge historical ocean data for developing numerical models. Hence, in this paper Machine Learning, based on less complex and easily deployable regression methods is exercised to identify the best prediction model for ocean currents. Further, all the regression methods performed were compared with the R2 score, Mean Absolute Error (MAE) and Mean Square Error (MSE). Among all methods, the Decision tree regression-based ML method performed best with 84% accuracy with minimal error. Qualitative performance is studied using visualization of data correlation, heat maps are also generated and compared.
实时动态洋流对水下航行器的精确导航具有重要意义。利用传统方法(如Navier-Stokes方程)估算和预测洋流,这些方法计算非常复杂,并且需要大量的历史海洋数据来建立数值模型。因此,在本文中,机器学习是基于不太复杂和易于部署的回归方法来识别洋流的最佳预测模型。进一步,将所有回归方法与R2评分、平均绝对误差(MAE)和均方误差(MSE)进行比较。在所有方法中,基于决策树回归的ML方法表现最好,准确率为84%,误差最小。利用数据关联可视化研究定性性能,生成热图并进行比较。

By 2024, the market for automated driving systems is anticipated to reach $20 billion, growing at a 25.7 percent annual pace between 2016 and 2024. Contour estimation through High-Resolution radars is one of the key functionalities of these growing industries and many techniques have been used for it. KNN-DBSCAN, Generalized Hough Transform, and brute force approach are some of the techniques studied. Size of encountered Radar cross-section (RCS), dependency on heuristics, accuracy, and computational expensive are some of the parameters against which comparison of the various techniques is done. Although these parameters are studied in-depth, there are parameters like interference and contamination of RADAR that have not been studied extensively in the literature.

Volume of video content surpass all other content types in internet. As per the reports from different sources, video traffic had acquired 82% of internet usage in 2022. Video is going to be more important in the years to come for user engagement, advertisement & marketing, news, education etc. Video information retrieval becomes an important problem to solve in this context. An accurate and fast video tagging system can aid a good content recommendation to the end users. It helps to audit the content automatically thereby platforms can control the contents which are politically and morally harmful. There are not many faster or cost-effective mechanisms to tag user generated videos at this moment. Manual tagging is a costly and highly time taking task. A delay in indexing the videos like news, sports etc., shall reduce its freshness and relevancy. Deep learning techniques have reached its maturity in the contents like text and images, but it is not the case with videos. Deep learning models need more resources to deal with videos due to its multi-modality nature, and temporal behavior. Apart from that, there are not many large-scale video datasets available at this moment. Youtube-8M is the largest dataset which is publicly available as of now. Much research works happened over Youtube-8M dataset. From our study, all these have a potential limitation. For example, in Youtube-8M, Video labels are only around 3.8K which are not covering all real-world tags. It is not covering the new domains which are created along with the surge in the content traffic. This study aims to handle this problem of tag creation through different methods available thereby enhancing the labels to a much wider set. This work also aims to produce a scalable tagging pipeline which uses multiple retrieval mechanisms, combine their results. The work aims to standardize the retrieved tokens across languages. This work creates a dataset as an outcome from ‘WikiData’, which can be used for any NLP based standardization use cases. An attempt has been made to do disambiguation through WikiId embedding. A new WikiData embedding is created in this work, which can be used for eliminating the tags which are noisy.
视频内容的数量超过了互联网上所有其他类型的内容。根据不同来源的报告,到2022年,视频流量占互联网使用量的82%。在未来几年,视频将在用户参与、广告和营销、新闻、教育等方面发挥更重要的作用。视频信息检索成为这一背景下需要解决的重要问题。一个准确、快速的视频标签系统可以为最终用户提供良好的内容推荐。它有助于自动审核内容,从而平台可以控制在政治和道德上有害的内容。目前还没有很多更快或更具成本效益的机制来标记用户生成的视频。手动标记是一项昂贵且耗时的任务。新闻、体育等视频的索引延迟会降低其新鲜度和相关性。深度学习技术在文本和图像等内容上已经成熟,但在视频方面还没有成熟。深度学习模型由于视频的多模态性质和时间行为,需要更多的资源来处理视频。除此之外,目前还没有很多大规模的视频数据集可用。Youtube-8M是目前最大的公开数据集。许多研究工作都是在Youtube-8M数据集上进行的。从我们的研究来看,所有这些都有潜在的局限性。例如,在Youtube-8M中,视频标签只有3.8K左右,这并不能覆盖所有现实世界的标签。它不包括随着内容流量激增而创建的新域名。本研究旨在通过不同的可用方法来处理标签创建的问题,从而将标签增强到更广泛的集合。这项工作还旨在产生一个可扩展的标签管道,该管道使用多种检索机制,并结合它们的结果。这项工作的目的是标准化跨语言检索的标记。这项工作创建了一个数据集作为“WikiData”的结果,它可以用于任何基于NLP的标准化用例。我们尝试通过嵌入维基id来消除歧义。本文提出了一种新的WikiData嵌入方法,该方法可用于去除带有噪声的标签。

This work also aims to produce a scalable tagging pipeline which uses multiple retrieval mechanisms, combine their results. The work aims to standardize the retrieved tokens across languages. This work creates a dataset as an outcome from ‘WikiData’, which can be used for any NLP based standardization use cases. An attempt has been made to do disambiguation through WikiId embedding. A new WikiData embedding is created in this work, which can be used for eliminating the tags which are noisy.","PeriodicalId":354855,"journal":{"name":"2023 11th International Symposium on Electronic Systems Devices and Computing (ESDC)","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114329586","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}

Pothole Detection has been a part of Advanced Driver Assistant Systems (ADAS) for a long time. To detect potholes, many techniques have been used. Deep learning-based methods have been particularly successful in this regard. However, the localization of the potholes accurately may not be possible only by having one modality of information. This work explores the multi-sensor information fusion (from Accelerometer and Gyroscope) to detect the potholes. Notably, most of the existing works proposed to make use of models such as Convolution Neural Networks, and other Attention models like Long Short-Term Memory (LSTM)’s, Gated Recurrent Units (GRUs), and Transformers. Despite having such proven architectures for complex and non-linear learning representations with attention units, still, the challenge of real-time deployments with optimized computing devices remains unaddressed. With the proposed approach, efficient deployments are possible on edge devices embedded in the vehicle providing a reliable ADAS solution for improved driver safety. The investigations and ablation study from the proposal focus on two-fold addressing the trade-off between model size and test accuracy. Significantly, the proposed hybrid architecture, the INN-former with quantization, achieved a size reduction by 16.12%, not compromising much with the maximum test accuracy reported at 96.12%. Similarly, pruning achieves a 1.115% size reduction with a minimal difference in test accuracy of 85.43% for the INN-former, and a 3.76% decrease in size while only a 4.95% decrease in test accuracy reported as 95.43% with the Attention model making use of GRU/ LSTM. Importantly, the proposed work discusses the design parameters for lightweight architectures investigating the pruning and quantization techniques that are not compromising the generalization capability of the models, which is highly essential for real-time deployments and validation.
洼坑检测作为高级驾驶辅助系统(ADAS)的一部分已经存在很长时间了。为了探测坑洼,使用了许多技术。基于深度学习的方法在这方面特别成功。然而,仅靠一种信息模式可能无法准确定位坑穴。本研究探索了多传感器信息融合(加速度计和陀螺仪)来检测坑穴。值得注意的是,大多数现有的工作都建议使用卷积神经网络等模型,以及其他注意模型,如长短期记忆(LSTM)、门控循环单元(gru)和变压器。尽管对于具有注意力单元的复杂和非线性学习表示有这样成熟的体系结构,但是使用优化计算设备进行实时部署的挑战仍然没有得到解决。通过提出的方法,可以在嵌入车辆的边缘设备上进行高效部署,提供可靠的ADAS解决方案,以提高驾驶员的安全性。该提案的调查和消融研究集中在两方面解决模型尺寸和测试精度之间的权衡。值得注意的是,所提出的混合架构,即带有量化的INN-former,实现了16.12%的尺寸减小,而最大测试精度为96.12%。同样,对于使用GRU/ LSTM的注意力模型,修剪实现了1.115%的尺寸减少,测试精度的最小差异为85.43%,而尺寸减少了3.76%,而测试精度仅下降了4.95%,为95.43%。重要的是,提出的工作讨论了轻量级架构的设计参数,研究了不会损害模型泛化能力的修剪和量化技术,这对实时部署和验证至关重要。

In recent years, each area has emerged with autonomous capabilities such as vehicular navigation, aquaculture, and industrial appliances. Especially, in the field of vehicular transportation, power is the main constraint for autonomous operations. The battery is the main source of energy or power storage. Especially, rechargeable batteries are potentially utilized as energy storage systems due to their high energy density. However, battery modelling is an indispensable tool for designing a real-time battery management system (BMS) that estimates the run-life time of autonomous battery power systems. In this paper, an easy-to-use battery Simulink model with time-varying dynamic load has been designed as a tool for all autonomous vehicles to estimate the State of Charge (SOC). This proposed model comprises a Controlled-Voltage source in series with internal resistance and time-varying resistive load. The proposed model differs from the ideal model by 0.01 (1%) and mirrors the general behaviour of the ideal model. The performance analysis of both the ideal and proposed model is evaluated by Root Mean Square Error (RMSE) which must be less than 0.4 to accept the battery model. However, the proposed model achieved the RMSE value of 0.1 and estimates SOC which is widely acceptable.
近年来,每个领域都出现了自主能力,如车辆导航、水产养殖和工业设备。特别是在车辆运输领域,动力是自动驾驶的主要制约因素。电池是能量或电能的主要来源。特别是,可充电电池由于其高能量密度,有可能被用作储能系统。然而,电池建模是设计实时电池管理系统(BMS)不可缺少的工具,该系统可以估计自主电池动力系统的运行寿命。本文设计了一个易于使用的具有时变动态负载的电池Simulink模型,作为所有自动驾驶汽车估计充电状态(SOC)的工具。该模型由一个具有内阻和时变电阻负载的串联控压源组成。所提出的模型与理想模型相差0.01(1%),反映了理想模型的一般行为。对理想模型和建议模型的性能分析均采用均方根误差(RMSE)进行评估,RMSE必须小于0.4才能接受电池模型。然而,该模型实现了0.1的RMSE值,并估计了广泛接受的SOC。

In today’s world, the UGC (User Generated Contents) videos have increased exponentially. Billions of videos are uploaded, played and exchanged between different actors. In this context, automatic video content classification has become a critical and challenging problem, especially in areas like video-based search, recommendation etc. In this work we try to extract frame-level visual and audio features, pre-extracted features are then converted into a compact video level representation effectively and efficiently. We aim to classify the video into a set of categories with high accuracy. From the literature survey, we identified that, the tagging of videos has been a problem which has not reached its maturity yet, and there are many researches happening in this area. It is observed that, the clustering based video description methodologies show a better result compared to the temporal algorithms. We also have identified that, majority of the SOTA techniques use the VLAD (Vector of Locally Aggregated Descriptors) technique to extract the video features and make the codebook learnable through some adjustments introduced in the NetVLAD. The key descriptors would be mostly noisy, and many of them are insignificant. In this work we aim to cascade a Self-Attention Block on the NetVLAD which can extract the significant descriptors and filter out the Noise. The YouTube 8M dataset shall be used for training the model and performance will be compared with other SOTA techniques. Like other similar works, model performance will be measured by GAP Metric (Global Average Precision) for all the videos predicted labels. We aim to achieve a GAP score close to 85% for this work.
在当今世界,UGC(用户生成内容)视频呈指数级增长。数以亿计的视频在不同的演员之间被上传、播放和交换。在此背景下,视频内容自动分类成为一个关键而具有挑战性的问题,特别是在基于视频的搜索、推荐等领域。在这项工作中,我们尝试提取帧级视觉和音频特征,然后将预提取的特征有效地转换为紧凑的视频级表示。我们的目标是将视频分类成一组准确率很高的类别。通过文献调查,我们发现视频的标注是一个尚未成熟的问题,在这一领域有很多研究。实验结果表明,基于聚类的视频描述方法比基于时态的视频描述方法具有更好的效果。我们还发现,大多数SOTA技术使用VLAD(局部聚合描述符向量)技术来提取视频特征,并通过在NetVLAD中引入的一些调整使码本可学习。关键描述符大多是嘈杂的,其中许多是无关紧要的。在这项工作中,我们的目标是在NetVLAD上级联一个自注意块,它可以提取重要的描述符并过滤掉噪声。将使用YouTube 8M数据集来训练模型,并将性能与其他SOTA技术进行比较。与其他类似的工作一样,模型性能将通过GAP度量(全球平均精度)对所有预测标签的视频进行测量。我们的目标是在这项工作中获得接近85%的GAP分数。
