Unsupervised Learning :-
In this type of learning one has to act without anyone's supervision or without any direction . Here the data is not labelled , there is no guide and the machine has to figure out the data set given and it has to find hidden patterns in order to make predictions about the output .
Example :-
How adults guide themselves to complete a particular task . They don't need anyone's guidance about completing a task as they can themselves take the decision because of their knowledge and past experiences .
