This is a brief summary of review talks given at the Valencia Summer School on Data Analysis in Cosmology and the 2005 UK National Astronomical Meeting. We describe the following examples: galaxy classification with principle component analysis, photometric redshift estimation with artificial neural ...
Selecting a compression utility to use will depend mainly on two factors, the compression speed and rate of a given tool. Unlike its counterparts,xzis not commonly used but offers the best compression. In this article, we will explain a number ofxz command examplesfor compressing and uncompressi...
Column-oriented databases allow for betterdata compressionratios compared to row-oriented databases. This is because compression algorithms can take advantage of the similar or repetitive values stored in each column. For example, dictionary encoding can be applied to store unique values in a dictionary...
Sorting algorithms are mainly used to rearrange large amounts of data in an efficient manner so that it can be searched and manipulated more easily. They are also used to improve the efficiency of other algorithms such as searching and merging, which rely on sorted data for their operations. ...
