              ●   Another example is that, due to less RAM, our mobile phone freezes. This means no playing games or messaging
                  through the phone.


                       Classification


              We use classification every day, classifying vegetables as ‘good to eat’ or ‘rotten’, classifying cats as per their breed or
              even classifying files as important or not important.


















              One more common example of classification is to identify spam emails. To create
              an email spam filter program, a developer can train a machine learning algorithm
              with a set of spam-like emails labelled “spam” and normal emails labelled “not
              spam”.

              The reason behind this is to train an algorithm that can identify spam emails from a set
              of emails and filter out non spam emails.
              In  order  to  understand  "Classification",  let  us  revise  the  concept  of  "Supervised
              Learning", because classification is type of supervised learning.

              Supervised learning is a subcategory of Machine Learning and Artificial Intelligence. It is also known as supervised machine
              learning. In supervised learning, we train the machine using well-labelled data, which means the data is already marked
              with the correct answer. After that, the machine is given a new dataset (training data) so that the supervised learning
              algorithm can analyse this data and produce the correct outcome.

              Let us take an example of vegetables. Now, you want to create a machine that can identify the vegetables
              one by one.
