How Facebook and Google uses Machine Learning at their best

"Machine learning will automate jobs that most people thought could only be done by people." Hello everyone, so today I will like to tell you how the most famous companies Facebook and Google uses Machine Learning at their best to ease their tasks and do cool stuffs that earlier was thought to be impossible. Have you ever wondered that how we learn or how from our birth our brain learns each and every bit, be it our parents and friend's faces or riding bicycles or learning mathematical formulas etc. It is because our brain observes whatever we see and makes patterns (which we call as experiences)and by analysing these patterns it predicts and makes further decisions. Due to this decision making power of our brain unlike computers the developers thought that why not we give prediction and decision making power to the computers which would add extra stars to the computers speed ie now computers can take decisions and do predictions as fast as they do calculations.
