Being one of the fastest developing deep learning aspects, TinyML has immense possibilities in areas where it is required to deploy a model that works on small and low power devices. Starting from imagery micro-satellite, tracking wildlife for conservation to detecting crop ailments, animal illnesses and predicting wildfires, TinyML comes with many possibilities. Not only it enables low-latency inference at edge devices consuming less power but also allows ML applications to run at edge intelligence.
‘OK, Google’ has been one of the renowned applications of TinyML, that works on everybody’s smartphones. With such applications in hand, along with software frameworks like TensorFlow Lite for Microcontrollers, it has become extremely easy to deploy TinyML models. Along with that, Tiny ML also comes with capabilities to support private machine learning applications and can work without any internet connection on edge devices.
With TinyML gaining massive traction in the industry, it has become critical for ML practitioners to get a comprehensive understanding of this aspect of deep learning. Here, we will share free online resources to get hands-on TinyML.
