The above can be classified as a clustering problem. Clustering, or cluster analysis, is the task of grouping a data
                 set into a set of similar items. It is an unsupervised learning algorithm. As an important analysis method in machine
                 learning, clustering is used to identify patterns and structures in unlabelled data sets. Clustering algorithms are used
                 in many fields, as given below.

                 Applications of Clustering

                 There are various applications of clustering. Let us learn about some of them.

                                                           If you are a CEO of a company, targeting the right candidates is critical.
                                                           Clustering algorithms group people with similar characteristics who
                                                           are most likely to sell your product or service. Once these groups have
                                                           been identified, target your messages around them to increase the
                                                           likelihood of sales.
                 Document Classification/Organisation
                 The algorithm views the text and groups/clusters it into different topics.
                 This  technique  allows  to  quickly  group  and  organise  similar  documents
                 using the characteristics given in the paragraph.
                 Recommendation Systems
                 Recommendation systems are widely used by Amazon, Netflix, Flipkart, etc. to provide automated and personalised
                 recommendations for products, services and information. The technology behind the recommendation engines is
                 called collaborative filtering. A cluster is formed based on the preferences of customers. Customers within each cluster
                 get recommendations computed at the cluster level.
