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.For example in a classifier, we know what training data belongs to what class, and so we train a function like a neural network to fit the data, and use the trained model to predict unseen data. In unsupervised learning, we don’t know the labels of our training data. We cannot create a direct mapping between inputs and outputs.Something went wrong and this page crashed!
