Autoencoders

What is an autoencoder? Autoencoders are neural networks that you can use to compress and reconstruct data . An autoencoder is a type of artificial neural network that takes some kind of input data which can be images, vectors, audio or whatever, and it first compresses the original input data into a lower dimension and then uses this lower dimensional representation of the data to recreate the original input! Autoencoder model architecture An autoencoder consists of three major components as illustrated above: An encoder which is a module that compresses the input data into an encoded representation that is several times smaller than the input data The Bottleneck or Code which contains the compressed representations And the decoder module that decompresses the bottleneck representation and tries to reconstruct the data back from its encoded form. Applications of autoencoder models Anomaly Detection Anomaly detection is a perfect example, where we train the model on normal ...
