Accelerating the pace of engineering and science. We will explore the concept of autoencoders using a case study of how to improve the resolution of a blurry image A noisy image can be given as input to the autoencoder and a de-noised image can be provided as output. By choosing the top principal components that explain say 80-90% of the variation, the other components can be dropped since they do not significantly benefit the model. Autoencoders can also be used for image denoising.
