F. Utro, in Computer Science Review, 2012 8.2 From pattern discovery back to compression There is a subtle interplay between compression and pattern discovery that, surprisingly, turn out to be deeply connected by the notion of motif discussed in this section. In fact, compression algorithms ...
1.3.1 Source Coding and Data Compression In computer science and information theory, data compression or source coding is the process of encoding information with fewer bits than an unencoded representation would use based on specific encoding schemes. As with any communication, compressed data communi...
Compression is important. With estimates of hundreds or thousands of exabytes of digital data in the world today, numbers big enough to be almost incomprehensible, and increasing even faster every year, compression helps to reduce storage, and increase network transmission speed. Compression is ...
we will refer to its more recent incarnation as a built-in feature of DAX Studio 3.0.11.It is interesting to note that VertiPaq is the original name given to the compressed column store engine within Analysis Services (Verti referring to columns and Paq referring to compression).Analyzing model...
Hundreds of petabytes are produced annually at weather and climate forecast centers worldwide. Compression is essential to reduce storage and to facilitate data sharing. Current techniques do not distinguish the real from the false information in data, l

“Shared Metadata and Data Formats for Big-Data Driven Materials Science”. We start from an operative definition of metadata, and the features that a FAIR-compliant metadata schema should have. We will mainly focus on computational materials-science data and propose a constructive approach for the...
