Multivariate data approximation with preprocessing of data
An adaptive information system is constructed in order to approximate a set of multidimensional data. To get better approximation properties a pre-processing stage of data is proposed in which the set of points, forming the multidimensional data base ...

PReaCH: A Fast Lightweight Reachability Index using Pruning and Contraction Hierarchies [PDF]
We develop the data structure PReaCH (for Pruned Reachability Contraction Hierarchies) which supports reachability queries in a directed graph, i.e., it supports queries that ask whether two nodes in the graph are connected by a directed path.

FastqPuri: high-performance preprocessing of RNA-seq data
Background RNA sequencing (RNA-seq) has become the standard means of analyzing gene and transcript expression in high-throughput. While previously sequence alignment was a time demanding step, fast alignment methods and even more so transcript counting ...

Using Entropy in Web Usage Data Preprocessing
The paper is focused on an examination of the use of entropy in the field of web usage mining. Entropy creates an alternative possibility of determining the ratio of auxiliary pages in the session identification using the Reference Length method.

Cooperative Downlink Multicell Preprocessing Relying on Reduced-Rate Back-Haul Data Exchange [PDF]
Different-complexity multicell preprocessing (MCP) schemes employing distributed signal-to-interference leakageplus-noise ratio (SILNR) precoding techniques are proposed, which require reduced back-haul data exchange in comparison with the conventional ...

Gene expression data preprocessing [PDF]
Abstract Summary: We present an interactive web tool for preprocessing microarray gene expression data. It analyses the data, suggests the most appropriate transformations and proceeds with them after user agreement. The normal preprocessing steps include scale transformations, management of missing values, replicate handling, flat ...

Data Preprocessing Toolkit : An Approach to Automate Data Preprocessing
-Data Pre-processing transforms the data into a format that is more easily and effectively processed in data mining, machine learning, and other data science tasks. The Data Pre-processing techniques are generally used at the earlier stages of the machine learning and AI development pipeline to ensure accurate results.

PREPROCESSING OF SATELLITE DATA FOR URBAN OBJECT EXTRACTION [PDF]
Very high resolution (VHR) DSMs (digital surface models) derived from stereo- or multi-stereo images from current VHR satellites like WorldView-2 or Pléiades can be produced up to the ground sampling distance (GSD) of the sensors in the range of 50 cm to
