    • Reliability: Edge AI reduces dependency on a constant internet connection, making it more reliable in areas with limited or unstable connectivity.
    • Efficiency: Processing data locally reduces the bandwidth required to send everything to the cloud, saving energy and costs.

    What are the Components That Make Edge AI Work?

    To understand how edge AI works, we must understand its main components and processes.

    Key Components

    Edge AI comprises three main components:

    • Edge devices
    • AI models
    • Communication

    Diverse Edge Hardware

    Edge devices encompass a wide range of hardware, from powerful servers capable of handling substantial computational loads to highly resource-constrained IoT sensors designed for specific tasks. These devices include:

    • Smartphones
    • Drones
    • Autonomous vehicles
    • Industrial robots
    • Smart home devices

    Some hardware manufacturers, like NVIDIA and Intel, even provide hardware support for deploying ML models on the edge.

    Optimized AI Models for Edge

    Edge AI employs various AI models, including machine learning, deep learning, and computer vision algorithms, optimized for efficient execution on edge devices. These models are tailored to operate within the constraints of edge environments, ensuring that they can perform effectively despite limited:

    • Processing power
    • Memory
    • Storage

    For instance, models like GPT-4o Mini and Llama 3.1 8B are designed to be lightweight and efficient, making them suitable for edge deployments.

    Efficient Edge-Cloud Communication

    Communication Protocols such as MQTT and REST APIs facilitate Efficient data exchange between edge devices and the cloud. These protocols enable seamless connectivity and data transfer, allowing synchronized operations between edge devices and central systems when necessary.

    They also allow the transfer of information in compressed form in an almost lossless fashion to keep crucial details intact.

    Lightweight Messaging for Constrained Networks

    MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for constrained devices and low-bandwidth, high-latency, or unreliable networks. It uses a publish-subscribe model, allowing devices to send (publish) and receive (subscribe) messages without a direct connection.

    This makes MQTT ideal for IoT applications where devices must communicate efficiently and reliably.

    Stateless Architecture for Networked Applications

    REST API (Representational State Transfer Application Programming Interface) is an architectural style for designing networked applications. It uses HTTP requests to access and use data. REST APIs are stateless, meaning each call from a client to a server must contain all the information the server needs to fulfill that request.

    This makes REST APIs scalable and suitable for various web services and applications, including those involving edge devices.

    What is the Process for Edge AI?

    The workflow that powers edge AI involves three steps: data collection, data processing, and action.

    Real-Time Information Gathering

    Data collection Edge devices continuously collect data from sensors, cameras, or other sources, providing a steady stream of information. This data can range from environmental metrics and health parameters to video feeds and audio recordings, forming the basis for real-time analysis. A great example of data collection is how your smartwatch collects the number of steps you took today.

    On-Device Insight Generation

    Data processing AI models deployed on edge devices process the collected data locally. This step involves analyzing the data to:

    • Extract meaningful insights
    • Detect patterns
    • Make predictions using AI models without relying on cloud resources.

    Local processing ensures that decisions can be made quickly, such as a self-driving car determining which lane to choose in real-time.

    Immediate On-Device Response

    Real-Time Action Based on the AI model's output, edge devices can take immediate action. These actions include:

    • Triggering alarms
    • Adjusting the path
    • Sending data to the cloud for further analysis

    Acting in real-time is essential for scenarios requiring instant responses, such as security systems or medical devices.

    5. Autonomous Vehicles and Robotics

    One example of Edge AI that everyone knows is a self-driving car. The car constantly collects data around it, which it then analyzes in real time. There is no time to move data back to the cloud since decisions must be made in the blink of an eye. Passenger aircraft have been highly automated for a long time.

    Real-Time Analytics for Smarter Mobility

    Real-time analysis of data collected from sensors can further improve flight safety. While fully autonomous and unmanned ships may not become a reality for years, modern ships already have extensive data analytics. For example, Edge AI technology can also be used to calculate passenger numbers and locate fast vehicles with extreme accuracy.

    More accurate positioning is the first step in train traffic and a prerequisite for autonomous rail traffic.

    6. Energy

    A smart grid produces a vast amount of data. A brilliant grid enables demand elasticity, consumption monitoring and forecasting, renewable energy utilization, and decentralized energy production. Nevertheless, a smart grid requires communication between devices, and transferring data through a traditional cloud service is not the best option.

    7. Retail

    Large retail chains have been doing customer analytics for a long time. The analytics primarily analyzes completed purchases, i.e., receipt data. Although this method can achieve good results, the receipt data doesn’t tell you:

    • How people move around the store
    • How happy they are
    • When they stop to watch something

    Video analytics, which analyzes fully anonymized data extracted from a video image, provides an understanding of people’s purchasing behavior that can improve customer service and the overall shopping experience.

    8. Predictive Maintenance

    Predictive maintenance involves monitoring equipment condition and predicting potential failures before they occur. By analyzing sensor data from machines and applying AI algorithms, Edge AI systems can identify patterns and anomalies that indicate potential issues. This allows maintenance to be scheduled proactively and reduces the risk of unexpected downtime.

    Define the Edge AI Application Problem Clearly

    Choosing a specific problem to address with Edge AI applications is essential. For example, detecting manufacturing defects in real-time using camera-equipped IoT devices helps prevent the costly consequences of faulty products. This problem helps focus the project and define success criteria to guide development.

    Collect Quality Datasets for Training AI Models

    Collect high-quality datasets for training AI models. This data can come directly from target edge devices or simulated environments. For example, sensor data from machines can predict faults or monitor performance. In the case of manufacturing defect detection, images of defective and non-defective products will help the model learn to classify new input accurately.

    Train the AI Model

    Then use frameworks like TensorFlow or PyTorch to train machine learning or deep learning models. This process involves feeding the collected datasets into the chosen framework and allowing the model to learn to recognize patterns in the data.

    Optimize Models for Edge Devices

    Once you’ve trained a model and it’s performing well according to your success criteria, apply optimization techniques like quantization, pruning, and model compression to reduce its size and computational requirements. These techniques help the model run smoothly on edge devices with limited resources.

    Select the Appropriate Edge AI Hardware

    It is essential to choose the appropriate hardware for your Edge AI application. Depending on the AI workload, this could include microcontrollers, single-board computers, or specialized AI accelerators. For instance, lightweight models can run on microcontrollers with limited resources.

    More complex models may require an edge device with an AI accelerator for efficient performance.

    Deploy the AI Model to the Edge Device

    Next, we must deploy the trained and optimized AI model to the edge devices. Once deployed, test for latency, accuracy, and reliability in real-world scenarios. Often, performance differs from test results obtained in controlled environments.

    Connect the Application to the Cloud

    To enhance the application, further connect it to cloud IoT platforms such as AWS IoT Greengrass, Azure IoT Edge, or Google IoT Core. These platforms support remote model updates, data storage, and scalability.
