Unsupervised learning is a type of machine learning where the algorithm is given input data without explicit instructions on what to do with it. In unsupervised learning, the algorithm tries to find patterns, structures, or relationships in the data without the guidance of labelled output. In unsupervised learning, the system attempts to find the patterns directly from the example given. So, if the dataset is labeled it is a supervised problem, and if the dataset is unlabelled then it is an unsupervised problem.
