In today’s tech-savvy world, we’re surrounded by mind-blowing AI-powered wonders: voice assistants answering our questions, smart cameras identifying faces, and self-driving cars navigating roads. They’re like the superheroes of our digital age! However, making these technological wonders work smoothly on our everyday devices is tougher than it seems. These AI superheroes have a special need: significant computing power and memory resources. It’s like trying to fit an entire library into a tiny backpack. And guess what? Most of our regular devices like phones, smartwatches, etc. don’t have enough ‘brainpower’ to handle these AI superheroes. This poses a major problem in the widespread deployment of the AI technology.

Hence, it is crucial to improve the efficiency of these large AI models to make them accessible. This course: “TinyML and Efficient Deep Learning Computing” by MIT HAN lab tackles this core obstacle. It introduces methods to optimize AI models, ensuring their viability in real-world scenarios. Let’s take a detailed look at what it offers:
