models which accelerate the successful deployment of intelligence mainly in EI is the principal way to solve these problems. In fact, Coral is so tightly integrated with Google’s AI ecosystem that its Edge TPU-powered hardware only works with Google’s machine learning framework… Third, we need to be able to evaluate how suitable the hardware system is for each specific EI application. The idea of knowledge transfer is to adopt a teacher-student strategy and use a pre-trained network to train a compact network for the same task[28]. toward enhancing ems prehospital quality,” in, J. Video Analytics in Public Safety(VAPS) is one of the most successful applications on edge computing since it has the high real-time requirements and unavoidable communication overhead. WSU researchers have developed a novel framework to more efficiently use AI algorithms on mobile platforms and other portable devices. receives the instruction of object detection, the model selector will choose a most suitable model from the optimized models based on the developer’s requirement (the default is accuracy oriented) and the current computing resource of the Raspberry Pi. The remainder of this paper is organized into six sections. 0 They consist of a consecutive sequence of one-dimensional filters that span every direction of three-dimensional space to achieve comparable performance as conventional convolutional networks [36]. First, to reduce the size of algorithms, many techniques have been proposed to reduce the number of connections and parameters in neural network models. As is shown in Figure 1, the development of EC techniques, including powerful IoT data, edge devices, storage, wireless communication, and security and privacy make it possible to run AI algorithms on the edge. aXeleRate – Keras-Based Framework for AI on the Edge. bandwidth, improve availability, and protect data privacy to keep data secure. Get the week's most popular data science and artificial intelligence research sent straight to your inbox every Saturday. In addition, the data transmission is greatly affected by the moving scenario and the extreme weather in the cloud computing. The second field represents the type of recourse, including the algorithm whose suffix is, At last, let echo the original example of building an object detection application on the Raspberry Pi to introduce the programming model and summarized the processing flow of. Meanwhile the emergence of novel applications calls for lower latency of the network. The second field represents the type of recourse, including the algorithm whose suffix is ei_algorithms and the data whose suffix is ei_data. TinyOS takes an event-driven design which is composed of a tiny scheduler and a components graph. Latency represents the inference time when running the trained model on the edge. Four key techniques that enable EI are explained in Section IV, including algorithms, packages, running environments, and hardware. Who We Are We’re an early stage venture spinout of SRI International , well-funded by industry-leading investors with support from Fortune 500 clients. Not only will edge chips and other components appear in appliances, devices, and sensors, they will introduce entirely new ways to tap AI, neural nets, and machine learning—while perhaps recapturing a sense of privacy that has been largely lost in the digital era. However, Amit Lal, professor of electrical engineering at Cornell University, believes edge AI could have an impact far beyond microwave ovens that let people bark out cooking instructions, or a hearing aid that automatically adjusts to the user and the surrounding environment. detection in ridesharing services,” in, L. Liu, X. Zhang, Q. Zhang, W. Andrew, and W. Shi, “AutoVAPS: an IoT-Enabled With the burgeoning growth of the Internet of Everything, the amount of data generated by edge increases dramatically, resulting in higher network bandwidth requirements. This allows some devices to operate for years or decades without a recharge or a new battery. "Right now, what we do at the edge is fairly basic, but within a few years we will likely see robust functionality," says Kurt Busch, CEO and co-founder of Syntiant Corp., a company developing Edge AI chips. The Bot Framework includes a modular and extensible SDK for building bots, as well as tools, templates, and related AI services. ∙ October 22, 2019 by Scott Martin Edge computing and donuts have one thing in common: the closer they are to the consumer, the better. Edge-edge collaboration has two aspects. Equation 1 depicts the desire to minimize Latency while meeting the Accuracy, Energy and Memoryfootprint requirements. To support EI, many techniques have been developed, called EI techniques, which include algorithms, software, and hardware. Another small network is the Xception network [37]; Chollet et al. AI-X provides an efficient HW-SW design framework for developing CNN-based models on GTI's chips. share, Edge intelligence, also called edge-native artificial intelligence (AI),... deployed an artificial neural network on wearable sensors to detect emotion [84]. Similar to Azure IoT Edge, Cloud IoT Edge [6], extends Google Cloud’s data processing and machine learning to billions of edge devices by taking advantage of Google AI products, such as TensorFlow Lite and Edge TPU. Moving edge AI off the drawing board and into everyday life will require a few other things. Today, a vehicle is not just a mechanical device but is gradually becoming an intelligent, connected, and autonomous system. It also has the ability to execute the trajectory tracking task collaborated with other OpenEI deployed edges. system for monocular, stereo, and RGB-D cameras,”, W. Liu, D. Anguelov, D. Erhan, C. Szegedy, S. Reed, C.-Y. Based on these two main requirements, EC arises, which refers to processing the data at the edge of the network. first proposed that the artificial intelligence processor should be deployed next to the camera sensors. Says Lal, "There are an incredible number of applications and possibilities for edge AI. From algorithms perspective, the cloud data centers train powerful models and the edge does the inference. Third is training on the edge locally. As part of a team that oversaw the NZERO program for the U.S. Defense Advanced Research Projects Agency (DARPA) between 2017 and 2019, Lal and others explored ultra-low-power or zero-power nanomechanical learning chips that could harness acoustical signals or other forms of ambient energy and wake as needed. https://searchhealthit.techtarget.com/definition/HITECH-Act, Institute of Computing Technology, Chinese Academy of Sciences, KubeEdge.AI: AI Platform for Edge Devices, Convergence of Edge Computing and Deep Learning: A Comprehensive Survey, AutoSOS: Towards Multi-UAV Systems Supporting Maritime Search and Rescue Machine Learning at the Network Edge: A Survey, https://deeplearn.org/arxiv/113246/machine-learning-at-the-network-edge:-a-survey. Intelligence in the home has been developed to some extent, and related products are available on the market. Biookaghazadeh et al. Robot Operating System(ROS)[51] is recognized as the typical representative of next the generation of mobile operating systems to cope with the Internet of Things. They found that no framework could achieve the best performance in all dimensions, which indicated that there was a large space to improve the performance of AI frameworks on the edge. The power of this framework lies in processing data exactly when and where it is needed. Edge Intelligence: The Convergence of Humans, Things, and AI, 2019 IEEE International Conference on Cloud Engineering (IC2E), 24-27 June 2019. https://ieeexplore.ieee.org/abstract/document/8789967, Murshed, M.G.S., Murphy, C., Hou, D., Khan, N.

In addition to criminal scene auto detection, for some applications like High-Definition Map generation, masking some private information like people’s face is also a potential VAPS application. knn for resource-scarce devices,” in, D. Dennis, C. Pabbaraju, H. V. Simhadri, and P. Jain, “Multiple instance The edge will be capable of dealing with video frames, natural speech information, time-series data and unstructured data generated by cameras, microphones, and other sensors without uploading data to the cloud and waiting for the response. Edge AI also could monitor the condition of underground pipes without any need to change a hard-to-reach sensor battery for decades. On the cloud, packages use a large-scale dataset to train deep learning models. Copyright © 2020 ACM, Inc. Today, it is not very straightforward to deploy the deep learning framework and run AI models on the edge because of the current complicated process to deploy and configure. large-scale image recognition,”, A. G. Howard, M. Zhu, B. Chen, D. Kalenichenko, W. Wang, T. Weyand, It distributes application computations between these layers," says Lauri Lovén, a doctoral researcher and data scientist at the University of Oulu in Finland. Such chips typically run machine learning algorithms as 8-bit or 16-bit computations, which optimizes local performance but also reduces energy consumption, in some cases by orders of magnitude. Two methods are used to optimize the algorithm for the edge. Flattened networks [35] are designed for fast feedforward EdgeX is a Linux Foundation project that is focused on providing a framework for IoT edge computing. In addition, researchers have also focused on the distributed deep learning models over the cloud and edge. The goal of OpenEI is that any hardware, ranging from Raspberry Pi to a powerful Cluster, will become an intelligent edge after deploying OpenEI. Others include Ambient, BrainChip, Coral, GreenWaves, Flex Logix, and Mythic. It is very important and urgent to develop a lightweight, efficient and highly-scalable framework to support AI … Moreover, these libraries must operate in different edge environments, including ad hoc clouds or cloudlets from different manufacturers. In order to execute AI algorithms efficiently, many deep learning packages are specifically designed to meet the computing paradigm of AI algorithms, such as TensorFlow, Caffe, MXNet, and PyTorch. If users call for the algorithm, the third field indicates the application scenario that OpenEI supports, including connected vehicles, public safety, smart home, and connected health. A. Y. Ng, “ROS: an open-source robot operating system,” in, Q. Zhang, Y. Wang, X. Zhang, L. Liu, X. Wu, W. Shi, and H. Zhong, “OpenVDAP: Home entertainment systems also benefit from EI to provide a better user experience. The retrained models will be uploaded to the cloud and combined into a general and global model. Epro and Mpro are the energy and memory footprint that the edge provides. Let us use an example of building an EI application to walk through the requirements of OpenEI. And thus, we design the “In-Edge AI” framework in order to intelligent-ly utilize the collaboration among devices and edge nodes to exchange the learning parameters for a better training and inference of the mod- "The cloud-native paradigm is a poor fit for the opportunistic, distributed, and heterogeneous edge computing environment, where devices appear and disappear, connections fail, and device batteries run out—and where user and edge devices have widely varying computational resources.". AI platform for Autonomous Driving. The benefit of involving EI in a smart home is twofold. Third is the preservation and sharing of medical data. AI for Earth puts Azure and Microsoft AI tools in the hands of those working to solve global environmental challenges through monitoring, research, and action. Model selecting can be regarded as a multi-dimensional space selection problem. [Online]. Health and biomedicine are entering a data-driven epoch, First is pre-hospital emergency medicine, where the emergent patient is been cared for before reaching the hospital, or during emergency transfer between hospitals, emergency medical service (EMS) systems are provided in the form of basic life support (BLS) and advanced life support (ALS). NVIDIA Corporation. 0 This article will shed some light on other pieces of this puzzle. “Big data for health,”, X. Wu, R. Dunne, Z. Yu, and W. Shi, “STREMS: a smart real-time solution proposed a reference architecture to deploy VAPS applications on police vehicles. Second, the EI platform may be equipped with multiple types of heterogeneous computing hardware, so managing the hardware resource and scheduling the EI application among the types of hardware to ensure high resource utilization are important questions. (2019) Hitech (health information technology for economic and clinical health) "Edge AI will enable new types of systems that can operate all around us at the beat of life and with data that is intimate and important to us," Verma explains. Ph.D. dissertation, Citeseer, 2014. Dean, M. Devin, The current approach of forcing data streams through a few large datacenters inhibits the capabilities of increasingly sophisticated digital technologies. OpenVDAP[52], Autoware[73], and Baidu Apollo[74] are open-source software frameworks for autonomous driving, which provide interfaces for developers to build and customize autonomous driving vehicles. applicable to edge computing directly due to the diversity of computing sources Considering the limitation of the status quo, EI is an alternative way to enhance EMS quality in terms of responsiveness and efficiency by building a bidirectional real time communication channel between the ambulance and the hospital, which has intelligent features like natural language processing, and image processing. Meanwhile, they should be lightweight enough and can be deployed on heterogeneous hardware platforms. Deploying edge computing solutions with NVMe provides the increased performance that is needed for artificial intelligence, machine learning and big data analytics. The development of EI requires much attention In addition to indoor activity detection, surveillance systems play an important role in protecting the home security both indoor and outside. [25], use singular value decomposition to reconstruct the weight of all connected layers, and they triple the speedups of convolutional layers on both CPU and GPU, and the loss of precision is controlled within 1%. Energy refers to the increased power consumption of the hardware when executing the inference task. from industry and academia due to its promise to reduce latency, save "Widely deployed cloudlets would fundamentally change the way data flows, processes take place, and machines handle decisions.". in, S. Zhang, W. Li, Y. Wu, P. Watson, and A. Zomaya, “Enabling edge intelligence Open Problems: There are several open problems that need to be addressed to be able to build data processing frameworks on the edge. If the application is urgent, the real-time machine learning module will be called to guarantee the latency. Compared with cloud versions, these frameworks require significantly fewer resources, but behave almost the same in terms of inference. Then, they developed EMI-RNN [42] and FastGRNN [43] in 2018. Without this framework, "Systems must depend on distant clouds and data centers to process data. Busch says future edge chips likely will take on different designs and features, depending on the use case. In this section, we summarize the key techniques and classify them into four aspects: algorithms, packages, running environments and hardware. However, memory on the edge is also limited. In recent years the two trends of edge computing and artificial intellig... Due to the edge's position between the cloud and the users, and the rece... Mismatch between edge platform and AI algorithms. Meanwhile, the active community and formation of the ecosystem put ROS in a good position to be widely deployed for edge devices. They chose three core applications on autonomous vehicles, which are localization, object detection, and object tracking, to run on heterogeneous hardware platform: GPUs, FPGAs, and ASICs. ", Satyanarayanan, M. and Davies, N. Edge AI means that AI algorithms are processed locally on a hardware device. To address these challenges, this paper proposes an Open Framework for Edge Intelligence, OpenEI, which is a lightweight software platform to equip the edge with intelligent processing and data sharing capability. Denton et al. Compression techniques are roughly categorized into three groups: Parameter sharing and pruning methods, low-rank approximation methods, and knowledge transfer methods [18, 19]. http://ip:port/ei_algorithms/home/power_monitor is used to call to execute the power monitoring algorithms on the edge. The first aspect is from the algorithm perspective, which is aimed at designing a lightweight model to support EI. Learn about AI on Azure. How does Raspberry Pi collaborate with others? As the prevalence of artificial intelligence (AI)-driven devices grows, researchers would like to bring some of that decision-making back to our own devices. acceleration,” in. To execute the AI tasks on the edge, some algorithms are optimized by compressing the size of the model, quantizing the weight and other methods that will decrease accuracy. First, home privacy will be protected since most of the computing resources are confined to the home internal gateway and sensitive family data is prohibited from the outflow. Accuracy is the internal attribute of AI algorithms. . , which is a mobile-optimized library for high-performance neural network inference. Second is smart wearable sensors. In the real world, we still need a software framework to deploy EI algorithms on the computing platform of connected and autonomous vehicle. ∙ CAVs are significant application scenarios for EI and many applications on CAVs are tightly integrated into EI algorithms, such as localization, object tracking, perception, and decision making. Amazon Web Services has introduced Wavelength, and Google has introduced Edge TPU, hardware and software solutions that accommodate edge functionality. Chen, presented a HashedNets weight sharing architecture that groups connection weights into hash buckets randomly by using a low-cost hash function, where all connections of each hash bucket have the same value. first proposed CAVBench[72], which takes six diverse on-vehicle applications as evaluation workloads and provides the matching factor between the workload and the computing platform. SafeShareRide[64] is an edge based detection platform which enables a smartphone to conduct real-time detection including video analysis for both passengers and drivers in ridesharing services. Developers of AI applications for edge deployment are doing their work in a growing range of frameworks and deploying their models to myriad hardware, software, and cloud environments. 0 Today, they can see, they can listen, and they can sense. Taking the above characteristic into account, some studies like TinyOS, ROS, and OpenVDAP are recognized as potential systems to support EI. It supports the CUDA and TensorRT libraries to accelerate EI applications in several scenarios, such as robot systems and autonomous vehicles. TinyOS[49] is an application based operating system for sensor networks. S. Bhatia, N. Boden, A. Borchers. A fundamental shift in AI Training A Distributed yet Collaborative Framework for training DL and ML at the Edge We allow any company, from any industry, to train complete DL and ML models, directly on their own edge devices. MobileNets are generated mainly from depth-wise separable convolutions, which were first introduced in the work of [33] and subsequently employed in Inception models [34]. http://jultika.oulu.fi/files/nbnfi-fe2019050314180.pdf, Rausch, T. and Dustdar, S. UPDATE JULY … To realize the example above, OpenEI should meet the following four requirements: ease of use, optimal selection, interoperability, and optimization for the edge. (2018) Qnnpack: Open source library for Considering the privacy of the home environment and the accessibility of smart home devices, it is completely feasible and cost-effective to offload intelligent functions from the cloud to the edge, and there have been some studies demonstrating EI capabilities. Cisco. This means a device can operate without a persistent connection to a dedicated network, or the Internet, and it can access remote connections and transfer data on an "as needed" basis. networks for feedforward acceleration,”, M. Wang, B. Liu, and H. Foroosh, “Factorized convolutional neural networks.” For example, criminal scene auto detection is a typical application of VAPS. Edge AI application developers and on-chip or on-device machine learning tasks will require ready-made tools and resources. Several questions may arise: how does Raspberry Pi collect, save, and share data? Most existing research on Edge AI, including federated learning and parameter servers, adopt a distributed machine learning framework, where the edge devices sepa- rately train their own models using the local data, while a centralized master located on the cloud iteratively coordi- nates the aggregation and update of the model parameters for the edge devices.
