YOUTUBE RECOMMENDATION SYSTEM…

For any company these days, the Recommendation system has become a vital part, every company wants to give a personalised experience to the user and for that Recommendation, systems are the best choice. LET'S UNDERSTAND WHAT IS A RECOMMENDATION SYSTEM… Let's say you want to buy a t-shirt from Amazon, you went to their website and type black t-shirt, You will see some Black T-shirts on your screen, Simple right??? Now let's say you liked some t-shirts on the first page and went inside to see them, lets say you select the third t-shirt from the left (BLACK PANTHER ONE), you checked its reviews, ratings, etc. Now you came back to the first page and select some different black t-shirts let's say with a round collar or maybe t-shirts with a particular brand etc. Now if you pay attention, Amazon is collecting every information, every click of yours, whenever you are going to a particular brand or particular pattern, Amazon has started to know your likings, disliking. It is the same like let's say you have gone to the nearest market to shop for a t-shirt with a new friend, the new friend did not know anything about your liking or disliking and he is just observing you, he is noticing every action of yours, What patterns you are choosing?? What brands you are choosing?? What color are you opting for?? Amazon is that unnecessary friend who is keeping a watch on you every time you are buying something on its website.
