Unsupervised Machine Learning

Unsupervised machine learning deals with unlabelled data. Unlike supervised learning, where the data is labelled with a specific category or outcome. Unsupervised learning algorithms are not given labelled data. Instead, it is given just input data $x$ without any corresponding output labels $y$, and its task is to find pattern or structure in that data.

Unsupervised learning algorithms

There are mainly 3 types of algorithms which are used for unsupervised dataset.

• Clustering
• Association rule learning
• Dimensionality reduction
