Full disclosure, this isn’t my project. I volunteer for a Seattle based nonprofit that puts on speaking events.

One of our speakers did a 5 minute talk about a cat door he created using machine learning.

His cat was bringing in dead animals to the house, so he created a cat door that will automatically lock for 15 minutes when the cat has something in its mouth. To do this he connected a camera to the cat door and used machine learning to check the image of the cat and whether the door should be locked or not.
