Machine learning is being introduced to schools more and more often. Also, thanks to Google AI Experiments, we have more opportunities to try something fun, simple and easy to understand what machine learning is. Recently, I have found that mBlock has an extension called Teachable Machine.
The principle is very similar to the one on Google AI experiment website. Give the computer enough amount of samples of target objects, and let it learn to know what this object look like. So once the computer feels confident about it, it'll make the right decision to recoginize the object.
According to this extension, I have created a mini project that could give students a quick taste of machine learning. I use paper with different colors to let the camera on my laptop to recognize the color and the LED will tell us which color the paper is.
Here's the video:
It's a very simple project because of the easy concept and circuit design as well as the block-based coding. But it's also a cool project that students could finish within two lessons.
I have attached the tutorial and slides here. Download link is here. Please feel free to use it if it works for you!
