Customer and audience segmentation, computer vision and breach detection can all apply unsupervised learning. These two types of unsupervised learning methods are among the most common. Clustering Clustering algorithms are the most widely used example of unsupervised machine learning.

A more general class of unsupervised learning algorithms can be built by predicting any part of the data from any other. For example, this could mean removing a word from a sentence, and attempting to predict it from whatever remains. By learning to make lots of localised predictions, the system is forced to learn about the data as a whole.

Unsupervised learning is a branch of machine learning that is used to find underlying patterns in data and is often used in exploratory data analysis. Unsupervised learning does not use labeled data like supervised learning, but instead focuses on the data’s features. Labeled training data has a corresponding output for each input.Let's take an example of the word “where”. It is broken down into the following n-grams taking n=3: where -: <wh, whe, her, ere, re> Then these sub-word vectors are combined to construct the vectors for a word. This helps in learning better associations among words in the language. Think of it as if we are learning at a more granular scale.
