A sparse signal is a signal that contains a significant amount of zeros or negligible values, with only a few non-zero or significant components. In various contexts, such as in signal processing or machine learning, sparsity implies that the signal can be effectively represented with fewer parameters or features than its dimension suggests. This property allows for more efficient storage, transmission, and processing of the signal. Sparsity is often leveraged in techniques like compressed sensing and feature selection.

What is meant by sparse in signal and image processing?
In signal and image processing, "sparse" refers to a representation where most of the signal or image data is zero or near-zero, with only a few significant non-zero values. This sparsity can facilitate more efficient storage, transmission, and processing, as only the essential components need to be retained. Sparse representations are often leveraged in techniques like compressed sensing, where the goal is to recover signals from fewer samples than traditionally required. Such representations are particularly useful in applications like image compression and denoising.
