Machine learning, specifically deep learning is at the core of many Google products, like Google Photos which can classify and group photos, like photos of your pets together automatically in an album. Note that this is now multiple machine learning models in one. First, it needs to identify whether or not the photo you just took is of a dog. Second, is to identify whether this dog is your pet based on comparing this photo in the history of photos you have with that specific dog. Now, let's take a quick demo of Google Photos. Nothing excites me more than talk about machine learning and when we can use a real-life application, especially one where I get to show you all these cool photos of my dog, Rex. So, here, I'm going to hop over into Google Photos, which is photos.google.com. It's one of the coolest products I think just because there's a lot of behind the scenes, quote/unquote, "magic", but now that you know what machine learning is, it's not really magic, just really highly performance tuned models. You can see that we can do some cool stuff. So, here's some photos, just move houses recently. You can see I got some house photos, and photos of my dog, and videos of my dog here as well. So, what we're going to try to do is to showcase some of the cooler features and things that you can do ML. One of the things that you can do, which I really like since I take a lot of photos, is automatic classification. So, I can just search on all the photos that I have. Searching for things like brown dog. Even without me manually labeling all of these because that would just take forever, finds photos and even videos, this is new to me where brown dogs are present somewhere in the video, which is cool. So, this automatic classification, the photos team is even taken it one step further, work and recognize the difference between, say a brown dog, and say my own pet, which happens to be Rex. So, if I just typed in Rex, somewhere along the way, it'll process and basically say, "Hey, we noticed you're taking a lot of these photos of the same dog. Do you want to say this is your pet?" Like, "Yeah. Sure, this is your pet." I think it works the same way with your kids as well. Basically, then learn what your pet looks like, and any new photos that you upload will automatically be added to your pets album. So, this is a shameless way for me to show cool pictures of Rex, but it also shows the underlying principles of lots of ML models automatically working as soon as you upload a photo into Google Photos. Give it a try yourself and then stick around for the rest of the course. We're going to be going into how you can actually invoke some of these image classification APIs to see what's inside of these photos, and then eventually work our way into building some models, like classification models ourselves. See you soon.
