[Downey] The team uses the same kind of machine learning that allows us to organize our photos or tag friends on social media, image recognition. First, models are trained using tagged images of things like cats or dogs. After looking at thousands of examples, the algorithm learns to identify new images without any human help. For the retinopathy project, over 100,000 eye scans were graded by eye doctors who rated each eye scan on a scale from one to five, from healthy to diseased. These images were then used to train a machine learning algorithm. Over time, the AI learned to predict which eyes showed signs of disease. [Dr. Lily Peng]

[Downey] The team uses the same kind of machine learning

00:00:03.836 --> 00:00:06.172

that allows us to organize our photos

00:00:06.206 --> 00:00:08.174

or tag friends on social media,

00:00:08.208 --> 00:00:10.944

image recognition.

00:00:10.977 --> 00:00:12.512

First, models are trained

00:00:12.545 --> 00:00:15.949

using tagged images of things like cats or dogs.

00:00:15.982 --> 00:00:18.001

After looking at thousands of examples,

00:00:18.084 --> 00:00:21.254

the algorithm learns to identify new images

00:00:21.287 --> 00:00:22.889

without any human help.

00:00:22.922 --> 00:00:25.292

For the retinopathy project,

00:00:25.325 --> 00:00:27.393

over 100,000 eye scans

00:00:27.427 --> 00:00:28.928

were graded by eye doctors

00:00:28.962 --> 00:00:32.465

who rated each eye scan on a scale from one to five,

00:00:32.498 --> 00:00:34.067

from healthy to diseased.

00:00:34.001 --> 00:00:35.735

These images were then used

00:00:35.768 --> 00:00:38.998

to train a machine learning algorithm.

00:00:38.104 --> 00:00:40.706

Over time, the AI learned to predict

00:00:40.074 --> 00:00:43.342

which eyes showed signs of disease.

00:00:43.376 --> 00:00:45.745

[Dr. Lily Peng] This is the assistant's view

00:00:45.779 --> 00:00:47.213

where the model's predictions

00:00:47.247 --> 00:00:50.075

are actually projected on the original image,

00:00:50.784 --> 00:00:54.554

and it's picking up the pathologies very nicely.
