There has been enormous growth in this field, all thanks to countless philosophers, mathematicians, and scientists who’ve worked towards achieving this. Following is a brief history depicting how the Machine Learning that we know has evolved:

  • The “Turing Test” was created by Alan Turing to prove Computers had intelligence in the year 1950.
  • Arthur Samuel wrote the very first algorithm in the Machine Learning space (in the year 1952).
  • The first neural network for a computer was designed by Frank Rosenblatt in the year 1957.
  • The basic pattern recognition algorithm “Nearest Neighbor” was written in the year 1967.
  • Stanford Cart” that can navigate through the obstacles in the room by itself was invented by the students at Stanford University in the year 1979.
  • The concept of Explanation-Based Learning (EBL) was coined by Gerald Dejong in the year 1981.
  • NetTalk, a tool that pronounces words just like a baby was invented in the year 1985 by Terry Sejnowski.
  • Machine learning shifted from the traditional knowledge-driven approach to a data-driven approach in the 1990s.

Real-World Machine Learning Examples

In this section, we will see some machine learning examples that are available for us to use. Most of us would have already come across these examples in some way or the other but probably you would have not realized that it is a Machine Learning use case that is being looked at. This section will cover some of these examples and explains how Machine Learning has been put to use in a certain industry space to reap benefits:


Facebook has it's a homegrown algorithm to target the social media space, targeting for specific customers and specific businesses. The relevance that Facebook gives to the ads presented to end-users is pretty spot-on, as this is done considering a lot of factors like user preferences, search history, and usage. To put this in a simpler way, Facebook is building its business by learning about its users and using this data for their advertisers. Deep Learning is what exactly Facebook puts to use, to classify the available data all by itself thereby enabling better learning for the models. Facebook puts Machine Learning to perfect use by employing techniques like textual analysis, facial recognition, targeted advertising, and designing newer artificial intelligence applications that feed on the previous data.


Amazon, a retail giant helps its customers purchase related products and/or products that go along with the purchased products.   The simplest example one can think of is the suggestions that Amazon provides to buy a phone back case and a screen guard when you purchase a smartphone: if you have viewed a product earlier, showing it as your viewed product to purchase it later. These techniques that are employed by these giants are nothing but simpler and targeted examples of Machine Learning. These provide the customers to review the related products based on their purchases, review their previous searches for later purchases, etc.


Netflix, a giant in the data/content space provides its services to a varied number of customers from different geographical locations as well. Providing the services to all these customers in a uniform manner has issues with emerging countries like Japan, India, and South Africa where there are data issues, bandwidth issues, etc. Using a Machine Learning algorithm as, like Dynamic Optimizer, Netflix provides its HD services to all the customers in a uniform manner. Dynamic Optimizer compresses the HD content to smaller sizes without compromising on the pixels but adjusting between frames. This is a unique way to provide their services to all the customers without having issues with the limited bandwidths of such customers.


Uber, the transportation giant, employs Machine Learning algorithms to provide the best of the services at the least possible fares to the end-users. Based on the frequency of cabs being booked from an area and individual, prices are fixed over and above the distance traveled through the cabs. This way, it provides better fares to the usual commuters from prominent places than ordinary commuters to remote destinations. Putting these algorithms to use, the tech giant is able to provide quality services at better and cheaper prices to the end-users. This has been coined as the Route based pricing system by Uber to cater to the needs and demands of customers.

Google Search:

One of the best sorted out search engines that is available is Google Search. Ever wondered what happens behind the scenes when a search query is presented to Google?. There are a couple of algorithms that we can assure they work behind the scenes whenever you present a search query to Google. One is the Knowledge Graph algorithm and the other is the PageRank algorithm. The PageRank algorithm counts the number of references that you make from one of your websites to the external world and based on these values, provides an estimated page rank to your webpage. More the links to the external world mean lesser is your page rank and lesser are the possibilities to show up in the Google search results.
