You are currently offline. The early application of autoencoders is dimensionality reduction. Semi-supervised autoencoder. To this end, our pro-posed algorithm can distinguish the task-relevant units from the task-irrelevant ones to obtain most effective features for future classification tasks. Starting from the basic autocoder model, this post reviews several variations, including denoising, sparse, and contractive autoencoders, and then Variational Autoencoder (VAE) and its modification beta-VAE. The first stage, the Part Capsule Autoencoder (PCAE), segments an image into constituent parts, infers their poses, and reconstructs the image by appropriately arranging affine-transformed part templates.
