Then, you should apply a unsupervised learning algorithm to compressed representation. Unsupervised Learning Method. It features denoising, unsupervised classification, time-frequency analysis, phase-space analysis, neural networks, time-warping and more. In unsupervised learning, an algorithm segregates the data in a data set in which the data is unlabeled based on some hidden features in the data. Unsupervised learning often experiences the curse of dimensionality, however subspace modeling can overcome this problem. Machine Learning with Matlab. Rory reviews typical workflows for both supervised (classification and regression) and unsupervised learning, through examples.
