Autoencoders are a type of unsupervised algorithm. It is utilized to transform multi-dimensional data into a lower-dimensional representation.

The reconstructing process involves three main components: the encoder, coder, and decoder. The encoder takes the input and compresses it into a representation in a latent space. This compressed representation is commonly referred to as the code. The decoder is responsible for reconstructing the code back to its original form.

The code layer, which is sometimes referred to as the bottleneck, plays a crucial role in the reconstruction of the input. Bottlenecks play a crucial role in determining what is important and what can be disregarded in the final outcome.

Applications of Autoencoders

Autoencoders are considered the best deep learning algorithms for colouring and compressing images.
