-This Learning Path is about TinyML. It serves as a starting point for learning how cutting-edge AI technologies may be put on even the smallest of devices, making Edge AI more accessible and efficient. You will learn how to setup on your host machine and target device to facilitate compilation and ensure smooth integration across all devices.

 In this section, you get an overview of the domain with real-life use-cases and available devices.
 
 ## Overview
-TinyML represents a significant shift in machine learning deployment. Unlike traditional machine learning, which typically depends on cloud-based servers or high-powered hardware, TinyML is tailored to function on devices with limited resources, constrained memory, low power, and less processing capabilities. TinyML has gained popularity because it enables AI applications to operate in real-time, directly on the device, with minimal latency, enhanced privacy, and the ability to work offline. This shift opens up new possibilities for creating smarter and more efficient embedded systems.
