‫Welcome to this section on machine learning.
‫So machine learning is not something you need to know
‫in-depth for the exam but there are a few
‫certification services that you need to know.
‫So the first one is Amazon Rekognition,
‫and as the name indicates, it's used to recognize objects,
‫people, text and scene in images and videos
‫using machine learning.
‫So you can do facial analysis and facial search
‫to do user verification and count people.
‫And with this, we can create a database of familiar faces
‫or compare against celebrities.
‫The use cases for Rekognition would be labeling,
‫content moderation, text detection,
‫face detection and analysis,
‫for example the gender, the age range and the emotions,
‫face search and verification, celebrity recognition,
‫and finally, pathing.
‫So if you wanna learn more, you can check out their website
‫which I think is very helpful.
‫So on the Rekognition websites,
‫we can we can automate our image and video analysis
‫with machine learning.
‫And I really like this website
‫because it shows you how it works.
‫So for example, for this image,
‫we can identify the elements of this image,
‫for example, a person, a rock and mountain bike,
‫a crest and outdoors.
‫We can label, for example, what we see in the images,
‫for example, Golden Retrievers or dogs.
‫Then I can look at content moderation
‫to make sure that it's appropriate for all ages.
‫I can detect text, for example for a run,
‫we want to see the numbers of each runner in the run.
‫We can do face detection and analysis.
‫For example, this person looks happy, she is smiling,
‫her eyes are open and she's a female.
‫Face search and verification,
‫maybe if you have a security application.
‫Finally, if you want to recognize a celebrity,
‫you can take a picture of them,
‫and this is the CTO of AWS.
‫And then finally, pathing.
‫For example, if you're monitoring a soccer game,
‫you could see where everyone is going to do
‫maybe some real time analytics.
‫So Rekognition is just a service you need to know
‫at a high level for the exam
‫but I really like this page
‫because it demonstrate the use cases.
‫I will see you in the next lecture.
