WebSparse coding is defined as learning an over-complete set of basis vectors to represent input vectors (<-- why do we want this) . What are the differences between sparse coding and autoencoder? When will we use sparse coding and autoencoder? machine-learning neural-networks unsupervised-learning deep-learning autoencoders Share Cite WebIn digital image processing, many signals are sparse; i.e., they contain many coefficients either equal to or close to zero in a specific domain. The objective of SR is to efficiently reconstruct the signal with a linear combination of a few dictionary atoms from the transformed signal domain [ 32 ].
