1. 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, by training the network to ignore insignificant data (“noise”). Variants exist, aiming to force the learned representations to assume useful properties. Examples are regularized autoencoders (Sparse, Denoising and Contractive), which are effective in learning representations for subsequent classification tasks, and Variational autoencoders, with applications as generative models. Autoencoders are applied to many problems, including facial recognition, feature detection, anomaly detection and acquiring the meaning of words. Autoencoders are also generative models which can randomly generate new data that is similar to the input data (training data).

1. Autoencoder

   An auto-encoder is an artificial neural network used for learning efficient codings. The aim of an auto-encoder is to learn a compressed representation for a set of data. This means it is being used for dimensionality reduction. Auto-encoders use three or more layers: ⁕An input layer. For example, in a face recognition task, the neurons in the input layer could map to pixels in the photograph. ⁕A number of considerably smaller hidden layers, which will form the encoding. ⁕An output layer, where each neuron has the same meaning as in the input layer. If linear neurons are used, or only a single sigmoid hidden layer, then the optimal solution to an auto-encoder is strongly related to PCA. Auto-encoders can also be used to learn overcomplete feature representations of data.
