Low rank and sparse decomposition
WebStatistical models at different levels of complexity are used to solve the SR problem—from the simplest closed-form regression, to sparse coding, to the complex deep neural networks (DNN). Recently, these methods were benchmarked based on the mean performance of the models and on a fixed set of real-world scenes, suggesting that more complex (more non … Web1 okt. 2024 · In this paper, we introduce a unified low-rank and sparse enhanced Tucker decomposition model for tensor completion. Our model possesses a sparse …
Low rank and sparse decomposition
Did you know?
WebSparse coding is a representation learning method which aims at finding a sparse representation of the input data (also known as sparse coding) in the form of a linear combination of basic elements as well as those basic elements themselves. These elements are called atoms and they compose a dictionary. WebLow-rank matrix approximation is a ubiquitous problem in data processing. Gradient descent has been employed for truncated SVD in large scale problems [3]–[6] and in related matrix completion settings [7]–[9]. The considered low-rank matrix approximation has also application in dictionary learn-ing for sparse signal representations.
