So then I used the a example of the Keras homepage for Browse other questions tagged unsupervised-learning keras. Montr eal (QC), H2C 3J7, Canada Editor: I. Autoencoder is unsupervised learning algorithm in nature since during training it takes only the images themselves and not need labels. BUT, WAIT! THIS ISN'T JUST ANY OTHER DATA SCIENCE COURSE:. Jamie Lendrum has addressed numerous typos in the first version. Introduction. Get to grips with the basics of Keras to implement fast and efficient deep-learning models This book starts by introducing you to supervised learning algorithms such as simple linear regression, the classical multilayer perceptron and more sophisticated deep convolutional networks.
