Binary autoencoder

WebMar 13, 2024 · Autoencoder. An autoencoder is a type of artificial neural network used to learn efficient codings of unlabeled data (unsupervised learning). The encoding is validated and refined by attempting to regenerate the input from the encoding. The autoencoder learns a representation (encoding) for a set of data, typically for dimensionality reduction ... WebApr 4, 2024 · Autoencoders present an efficient way to learn a representation of your data, which helps with tasks such as dimensionality reduction or feature extraction. You can even train an autoencoder to identify and remove noise from your data.
