Can vectors be compressed

WebBitMagic v.7.1.0+ implements XOR compression for bit-transposed vectors (integers and strings) and collections of sparse vectors (data frames). This type of compression fits well with the concept of bitwise transposition and can be successfully used on collections of correlated or aligned data frequently seen in the areas of big data like ... WebAug 16, 2024 · When a matrix like ~X X ~ contains redundant information, that matrix can often be compressed: i.e. it can be represented using less data than the original matrix with little-to-no loss in information. One way to perform compression is by using LRA.

WebJul 25, 2016 · Abstract. The problem of compressing a large collection of feature vectors is investigated, so that object identification can be processed on the compressed form of the features. The idea is to perform matching of a query image against an image database, using directly the compressed form of the descriptor vectors, without decompression. WebNov 1, 2004 · Based on this observation, the compression of normal vectors can be approached by choosing a few normal vectors that can represent all normal vectors without too much sacrifice of the visual appearance of the model.
