WebIn computer science, a sparse file is a type of computer file that attempts to use file system space more efficiently when the file itself is partially empty. This is achieved by writing brief information representing the empty blocks to the data storage media instead of the actual "empty" space which makes up the block, thus consuming less storage space. WebApr 7, 2024 · Data augmentation has attracted a lot of research attention in the deep learning era for its ability in alleviating data sparseness. The lack of labeled data for unseen evaluation databases is exactly the major challenge for cross-domain text-to-SQL parsing.

WebFor example, in this paper I believe the author is using "sparsity" as a quality or a characteristic of a set (in the boolean sense: either it has it or it doesn't ), and "sparseness" as a metric (referring to the "degree of", or "the measure of" sparseness). But even there I think it's a stretch; the words seem to be interchangeable.

WebJul 10, 2024 · Data sparsity is mostly a computational problem. Think of a recommender system that recommends thousands of products to hundreds of thousands of users, if you stored the data about user-product interaction in a matrix, it would be a huge amount of data consisting of lots of zeros (most users are interested just in a selected subset of products). WebSep 19, 2024 · By using the results of previous factorization involved in iterative computation with sparseness constraint, the cost of computation is reduced and the sparseness of data after factorization is greatly improved.
