In this paper, we deviate from recent works, and advocate a two-step approach where feature learning and clustering are decoupled. Semi-supervised learning methods try to leverage the underlying structure of the data to fit labels to the unlabeled data. Unsupervised learning is a type of machine learning algorithm used to draw inferences from datasets consisting of input data without labeled responses.. Several recent approaches have tried to tackle this problem in an end-to-end fashion. Semi-supervised learning combines aspects of supervised learning, where all of the training data is labeled, and unsupervised learning, where true labels are unknown. Explore the fundamentals behind machine learning, focusing on unsupervised and supervised learning. I have a large dataset (2+ millon points) containing 3 variables which I want to cluster/ classify into 3 groups based on the variation of those 3 variables. This is roughly how unsupervised learning happens. Rory reviews typical workflows for both supervised (classification and regression) and unsupervised learning, through examples. The app can automatically identify your predictors and response variables based on your data type. The idea is that you should apply autoencoder, reduce input features and extract meaningful data first.
