Question
Q.27 What is unsupervised learning?1. Number of groups may be known2. Features of group explicitly stated3. neither feature nor number of groups is known4. None of above
Solution
The correct answer is 3. In unsupervised learning, neither the features nor the number of groups is known. This type of machine learning involves the use of machine learning algorithms to find patterns in datasets containing data points that are neither classified nor labeled. This allows the model to act on that information without guidance. Here the task of the machine is to group unsorted information according to similarities, patterns and differences without any prior training of data.
