Dictionary sparse
WebSparse approximation ideas and algorithms have been extensively used in signal processing, image processing, machine learning, medical imaging, array processing, data mining, and more. In most of these applications, the unknown signal of interest is modeled as a sparse combination of a few atoms from a given dictionary, and this is used as the ... WebApr 10, 2024 · Abstract. This letter proposes a deep-learning-based method for time of arrival (TOA) estimation with a new sparse encoding scheme, aiming to solve the problems caused by quantization errors and off-grid effects. The proposed method utilizes a convolutional neural network (CNN) to learn the relationship between the training signals …

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 ].
WebWhat is a sparse matrix? A sparse matrix is a special case of a matrix in which the number of zero elements is much higher than the number of non-zero elements. As a rule of thumb, if 2/3 of the total elements in a matrix are zeros, it can be called a sparse matrix.
