If facebook, instagram, messanger, google assistant, online shopping, email have become inseparable part of your daily life, then it can be fairly stated that much of your digital experiences are powered by Artificial Intelligence. Your smartphone is indeed becoming smarter.

In this Article, we will discuss three questions: How facebook uses AI to give you more personalised experiences? How AI is behind many of the google's products you use in your daily life? and How Amazon uses AI to improve shopping experiences of users?

How facebook uses AI

Facebook is a free service! Well, free in terms of you not having to pay for using the platform. But, whether you realise it or not, you are getting to use facebook at the cost of your personal data you share with facebook. You share your personal data with facebook, upload pics, watch videos you like, like posts and comments, play games you like and chat with friends. All these things that you do on facebook help facebook know about you, your likes and dislikes. And facebook sell this data of yours as a package to advertisers. This is the basic revenue model of facebook. And this should explain why you see what you see as ads on various websites you visit.

As of now, there are over 2.2 billion monthly active users on facebook. To manage data of this scale and make sense of the data of each user, facebook uses DeepLearning. Lets consider some specific cases where facebook uses deeplearning to make sense of our data:

DeepText: a text understanding engine

DeepText can understand what you post on facebook as text. The question is, among your friend circle you use peculiar words and local languages. Can DeepText understand them? The answer is YES and even more. DeepText is designed to be language agnostic, meaning it is not dependent on any specific language. DeepText uses a deeplearning concept called "Word Embeddings" which preserves the semantic relationship among words.

Face Recognition

Facebook uses DeepFace to teach it to recognize people in photos. This advanced face recognition tool has reached an accuracy of 97.35% closely approaching human-level performance. Using this feature, facebook lets you tag people quickly and easily, help protect you from strangers using a photo of you as their profile picture,help people with visual impairments by telling them who's in a photo or video, and let you know when you might appear in photos or videos, but haven't been tagged.

How Amazon uses AI to improve shopping experiences of users?

An e-commerce giant like Amazon meet customers on customers' own terms. You as a customer are shown what you want to see and you are provided with the right information to make decisions and purchases. Below are some products of Amazon powered by AI:

Shopping Assistants

Beauty brand Coty partnered with Amazon to launch "Let's Get Ready", a new visual skill designed specifically for Amazon Echo Show, the first Alexa-enabled voice device with a screen. This feature allows users to input personal attributes, including hair, eye and skin color, and Coty supplies on-demand, occasion-based look planning service, capable of delivering more than 2,000 combinations of hair and makeup looks. Users have the ability to add related products from each look to their Amazon shopping cart via voice. The interface can also provide curated tutorials and quick tips, thereby acting as a user’s personalized style assistant.

Tailored Recommendations

The tailored recommendations you see on the Amazon site is made possible by machine learning and artificial intelligence. Every user is different. The goal of tailored recommendations is to understand the user and give the best shopping experience by showing only those products that the user would want to see.

Contactless Shopping

Contactless shopping is making cash obsolete. Contactless is the future of shopping. The latest example of contactless shopping is Amazon GO. Amazon GO has taken shopping to another level. Customers simply walk in, take what they like off the shelves and walk out: no chasiers at all.

Amazon GO employs computer vision, sensor fusion, and deep learning to identify customers that walk into the store and items they pick. Amazon GO can detect when products are taken from or returned to the shelves and keeps track of them in a virtual cart.
