How an AI Can "See"
AI in Daily Life - Self Driving Cars
Have you seen a self driving car?
Have you seen one in the news or in the movies?
How do you think they work?
They use an AI to detect different objects in their surroundings and navigate
Did you know AI can also understand pictures/images ? But how?
How do computers store images?
Images are stored as Pixels. Each Pixel is one number or a set of numbers
The more pixels an image has, the harder it is for a human to see the pixels
How many pixels do images have today?
Ask the students to Google for the answer
Most modern day cameras have between one million and ten million pixels per image
How Pixels Become Images:
Lets Try an AI for Images
Now that we have seen that images are made up of Pixels, or are lots of numbers. what can an AI do with these numbers?
Do this exercise
Give the students 10-15 minutes to try QuickDraw
Show them what the summary page for QuickDraw shows. This video describes what you can show them. The video is also embedded below.
How do we think this AI learned?
It had lots of pictures of drawings of different things
It learned patterns of what each object looked like
When we draw a new object - it tries to find a pattern that matches
If our drawings look like other people's - it will guess the right answer
Any ideas of what we can do with these types of AIs?
Find people by their faces?
Diagnose diseases by looking at pictures of skin, X-Rays etc? Did you know that doctors can now diagnose COVID-19 by looking at X-Rays?
Detect healthy plants and diseased plants?
