Edge AI: What, How and Why?

Edge AI, short for Edge Artificial Intelligence, refers to deploying artificial intelligence algorithms and models directly on edge devices, such as smartphones, IoT devices, and edge servers, rather than relying solely on centralized cloud servers for processing. This approach brings the power of AI directly to the source of data generation, allowing for real-time processing, reduced latency, and improved privacy and security. In essence, Edge AI enables devices to make intelligent decisions locally without constantly sending data back and forth to remote servers. It’s a game-changer for healthcare, manufacturing, and autonomous vehicles, where quick decision-making and data privacy are paramount.

Edge AI is now at the forefront as businesses seek automation to streamline operations, improve efficiency, and enhance safety measures. Recent advancements in neural networks, computing infrastructure, and the widespread adoption of IoT devices have paved the way for deploying AI models directly on edge devices. This enables real-time processing of data, ensuring faster insights and decision-making capabilities. Moreover, the maturation of neural networks has enabled generalized machine learning, allowing organizations to train AI models effectively and deploy them in production at the edge.

The widespread adoption of IoT devices has further fueled the growth of Edge AI, as it provides the necessary data and devices required to deploy AI models at the edge. With the ability to gather data from industrial sensors, smart cameras, and robotics, Edge AI enables businesses to harness insights and drive innovation across various sectors.
The benefits of Edge AI are manifold. Firstly, it offers real-time data processing, enabling high-performance computing power at the edge where IoT devices and sensors are located. This facilitates faster insights and decision-making capabilities, particularly in scenarios such as autonomous vehicles, where milliseconds can significantly affect collision prevention.

Furthermore, Edge AI ensures better privacy by processing data locally on edge devices, reducing the risk of data mishandling or misuse. This localized data processing also results in lower internet bandwidth usage and reduced data transfer to the cloud, leading to business cost savings.
Moreover, Edge AI solutions contribute to lower power consumption as data is processed locally, eliminating the need for constant connectivity to cloud services. This saves energy and improves efficiency, especially in remote locations with limited power supply.

Edge AI holds immense potential to revolutionize various industries by bringing intelligence closer to where data is generated. With its ability to enable real-time processing, ensure better privacy, reduce latency, and lower power consumption, Edge AI is poised to drive innovation and efficiency across sectors.

How does it work?
Edge AI technology leverages deep neural networks (DNNs) to mimic human intelligence, enabling machines to perceive objects, interpret speech, and perform other human-like tasks. In this process, DNNs are trained with vast amounts of data to respond to specific queries accurately. This training, known as ‘deep learning,’ typically takes place in data centers or the cloud due to the substantial data requirements and the need for collaboration among data scientists. Once trained, the model becomes an ‘inference engine’ capable of addressing real-world problems.

In edge AI deployments, the inference engine operates on a local computer or device in remote locations such as factories, hospitals, automobiles, and residences. When the AI encounters a problem, the relevant data is often sent to the cloud to train the original AI model further. This feedback loop is crucial for enhancing model performance, as edge AI models continuously learn and improve over time. As a result, edge AI solutions become more innovative and efficient with each iteration, contributing to advancements in various industries.
