In an unsupervised learning setting, it is often hard to assess the performance of a model since we don't have the ground truth labels as was the case in the supervised learning setting.

An unsupervised learning model's goal is to identify meaningful patterns among the data. In other words, the model has no hints on how to categorize each piece of data, but instead it must infer its own rules. A commonly used unsupervised learning model employs a technique called clustering. The model finds data points that …Unsupervised machine learning methods are particularly useful in description tasks because they aim to find relationships in a data structure without having a measured outcome.
