“…Compared with predefined dictionaries, learning dictionaries, such as K-SVD [16], [17] and online learning method (OLM) [18], can obtain a compressed model by training the signal characteristics, leading to better sparse representation performance for the original signal. Souza et al [19] and Zhao et al [20] used the K-SVD learning dictionary to compress the electrocardiogram (ECG) signal and forest ecological data, reducing energy consumption.…”

“…Specifically, LSA represents the relationship between documents and terms by a term-document matrix that is further decomposed into a product of three other matrices by the singular value decomposition (SVD) [ 1 , 3 , 4 ]. SVD is the mathematical tool behind LSA and some applications including association prediction [ 21 ], similarity computation [ 22 , 23 ], clustering [ 24 , 25 ], images analysis [ 26 ] and collaborative filtering [ 27 , 28 ]. For the given query, LSA transforms it into a pseudo document vector and computes the similarities between query and candidate documents over the SVD result of the term-document matrix.…”
