What is Edge AI? Everything You Need to Know about Edge AI

Last update: 30/12/2024

From self-driving cars to wearables delivering instant health updates, edge AI has quietly revolutionized how we live and work. Combining two cutting-edge technologies - artificial intelligence and edge computing, it reflects how powerful an innovative technology can be. But what exactly is edge AI, how does it work, and how is it shaping the future? Dive into our post to find out everything you need to know about edge AI.

1. What is Edge AI?

Edge AI refers to the powerful combination of artificial intelligence (AI) and edge computing, which enables data processing and analysis directly on local devices, such as IoT sensors, smart appliances, or wearable technology. 

Unlike traditional AI systems that rely heavily on cloud infrastructure, edge AI processes data near its source, providing real-time insights and reducing dependency on external networks.

2. How is Edge AI different from other types of AI?

When learning about edge AI, you may come across related terms like distributed AI and cloud AI. Let’s erase the confusion.

Edge AI vs. Distributed AI

Edge AI and Distributed artificial intelligence (DAI) are both transformative approaches in the AI landscape, but they differ in how they process data and deploy AI models.

Edge AI focuses on localized decision-making, allowing devices to process data and make decisions directly on the edge - such as sensors or IoT devices - without constant reliance on a central server. This reduces latency, enhances privacy, and facilitates real-time responses. However, training and updating these models often require transferring data to the cloud. Scaling Edge AI across multiple locations can face challenges like resource constraints, heterogeneity, and managing vast data volumes.

Distributed AI, on the other hand, addresses these limitations by distributing tasks and coordinating processes across interconnected systems, including edge devices and central servers. It automates AI workflows, manages data intelligently, and scales applications across diverse environments. Unlike Edge AI, Distributed AI is designed for large-scale, multi-agent environments, where distributed computing helps tasks be divided among multiple devices or systems. 

Edge AI vs. Cloud AI

Edge AI and Cloud AI are two distinct approaches to implementing artificial intelligence, each tailored to different needs and offering unique advantages.

While Edge AI processes data directly on local edge devices, Cloud AI relies on remote servers to store and process data. Below are the key differences between edge AI and cloud AI.

  • Latency: Edge AI processes data in real time on local devices, ensuring faster response times compared to Cloud AI, which requires sending data to distant servers.
  • Computing power: Cloud AI has the advantage of powerful servers, enabling more advanced AI models, while Edge AI is limited by the device's processing capacity.
  • Network bandwidth: Edge AI reduces bandwidth usage by avoiding constant data transmission, whereas Cloud AI requires significant bandwidth for sending and receiving data.
  • Privacy: Edge AI keeps sensitive data secure by processing it locally, whereas Cloud AI may expose data to third-party servers, raising privacy concerns.

3. How does edge AI work?

Edge AI combines advanced deep learning techniques with localized processing to enable devices to perform intelligent tasks in real time. Here's a breakdown of how edge AI works:

Model training in the cloud
Firstly, an edge AI model is trained using large datasets in centralized systems like data centers or cloud platforms. The training process, known as deep learning, involves feeding the model examples paired with correct answers until it can generalize to new, unseen data.

Deployment to edge devices
Once trained, the model transitions into an inference engine - a version optimized to process real-world data. This inference engine is deployed to local devices such as IoT sensors, cameras, autonomous vehicles, or medical equipment.

Local processing and decision-making
At the edge, the inference engine analyzes data directly on the device, enabling tasks like recognizing objects, understanding commands, or providing recommendations. This local processing eliminates the need to constantly transmit data to the cloud.

Continuous improvement with feedback loops
When the AI encounters challenges or anomalies, the problematic data is sent back to the cloud for further training. This updated model can later replace the existing inference engine at the edge, creating a feedback loop that continuously improves the system's performance over time.

4. Benefits of edge AI

Edge AI is driving the next wave of innovation, offering numerous advantages that make it a valuable tool for businesses, including:

Low latency and real-time analytics

Latency, or delay in response, is the biggest enemy when it comes to operating a system. Edge AI eliminates this by processing data locally on devices, ensuring immediate responses and enhances real-time application performance. This allows for timely decision-making without relying on constant internet connectivity.

Privacy preservation

Since sensitive data is processed and stored locally, edge AI minimizes the risk of data breaches during transmission. This localized approach helps organizations meet strict data sovereignty and compliance requirements.

Lower bandwidth requirements

Local processing significantly reduces the amount of data that needs to be transmitted over the network. This not only preserves bandwidth but also improves the capacity to handle multiple devices simultaneously.

Operational cost savings

By reducing reliance on cloud resources for data processing, edge AI cuts costs associated with cloud storage, internet bandwidth, and server workloads. This distributed processing also reduces the need for continuous supervision by data scientists, further saving operational costs.

Improved reliability

Decentralized processing ensures higher system availability and robustness. Edge AI applications can continue functioning even without internet access, making them ideal for mission-critical operations.

Scalability

Edge AI can handle large-scale deployments by integrating with devices equipped with native edge capabilities. This scalability supports seamless system expansion without overloading cloud infrastructure.

Persistent improvement

Edge AI systems grow smarter over time through feedback loops. When faced with unfamiliar scenarios, the data is sent back to the cloud for retraining, ensuring that models deployed at the edge continually improve.

5. Applications of edge AI

Businesses across various industries are leveraging edge AI to revolutionize their operations. Let’s explore how edge AI is driving innovation and solving real-world problems.

Edge AI in retail

Edge AI is revolutionizing the retail sector by enhancing customer experiences, improving inventory management , and streamlining operations.

  • Smart shelves and inventory management: Retailers are using edge AI to power "smart shelves" that monitor stock levels in real-time. Sensors and cameras detect when items are out of stock or misplaced, sending alerts to staff for immediate replenishment or reorganization. This helps maintain accurate inventory and optimize product availability.
  • Checkout-free stores: Many retailers are adopting edge AI for checkout-free shopping experiences. Edge AI systems track products that customers select or return using data processed directly from in-store sensors and cameras. This enables seamless, automated transactions without the need for traditional checkout processes, enhancing convenience for customers.
