Unsupervised learning can be motivated from information theoretic and Bayesian principles We brie?y review basic models in unsupervised learning including factor analysis PCA mixtures of Gaussians ICA hidden Markov models state-space models and many variants and extensions
The term “unsupervised learning” or “learning without a teacher” is generically associatedwith the idea of using a collection of observationX1 Xnsampled from a distributionp(X)to describe properties of p(X) This de?nition is extremely generic and could describe forexample any procedure of descriptive statistics
common features across many small datasets and perform zero shot learning 1 Introduction Unsupervised Learning (UL) is an elusive branch of Machine Learning (ML) including problems such as clustering and manifold learning that seeks to identify structure among unlabeled data UL is notoriously hard to evaluate and inherently unde?nable
The primary difference between supervised and unsupervised learning is whether the data has labels. If the person developing the computer program labels the data, they are helping or "supervising" the machine in its learning process. Supervised learning applies labeled input and output data to predict results.
Applications: Supervised learning models are ideal for spam detection, sentiment analysis, weather forecasting and pricing predictions, among other things. In contrast, unsupervised learning is a great fit for anomaly detection, recommendation engines, customer personas and medical imaging.
Goals: In supervised learning, the goal is to predict outcomes for new data. You know up front the type of results to expect. With an unsupervised learning algorithm, the goal is to get insights from large volumes of new data. The machine learning itself determines what is different or interesting from the dataset.
To put it simply, supervised learning uses labeled input and output data, while an unsupervised learning algorithm does not. In supervised learning, the algorithm “learns” from the training dataset by iteratively making predictions on the data and adjusting for the correct answer.
