Wavelets with Frame Multiresolution Analysis

A frame multiresolution (FMRA for short) orthogonal wavelet is a single-function orthogonal wavelet such that the associated scaling space V0 admits a normalized tight frame (under translations). In this paper, we prove that for any expansive matrix A with integer entries, there exist A-dilation FMRA orthogonal wavelets. FMRA orthogonal wavelets for some other expansive matrix with non integer ...

understanding Platform-Based Digital Currencies

ƒ This article focuses on digital currencies issued by Internet platforms such as Facebook and Amazon. Depending on the platform’s business model, its digital currency may be equipped with different attributes that affect how users can acquire, transfer or redeem the digital currency. In most cases, platforms restrict the functionality of their digital currencies to enhance the business model a...

Multiresolution Document Analysis with Wavelets

The n-gram analysis technique breaks up a text document into several n-character long unique grams, and produces a vector whose components are the counts of these grams. A typical corpus contains hundreds of thousands of such grams. Wavelet compression reduces the dimension of the n-gram vectors, and speeds up document query operations. Document vectors with their dimensions reduced to four com...
