Performance analysis of clustering techniques over microarray data: A case study

Physica A: Statistical Mechanics and its Applications, 2018
Abstract Handling big data is one of the major issues in the field of statistical data analysis. In such investigation cluster analysis plays a vital role to deal with the large scale data. There are many clustering techniques with different cluster analysis approach. But which approach suits a particular dataset is difficult to predict. To deal with

Similarity analysis of feature ranking techniques on imbalanced DNA microarray datasets

2012 IEEE International Conference on Bioinformatics and Biomedicine, 2012
DNA microarrays are a modern advancement in the analysis of genetic data. This technology allows a researcher to test samples for thousands of genes simultaneously. However, once the samples in the DNA microarrays have been tested, the researcher must then search through the data collected and identify genes important to their problem.

An improved SOM-based visualization technique for DNA microarray data analysis

The 2010 International Joint Conference on Neural Networks (IJCNN), 2010
Effective and meaningful visualization techniques are quite important for multidimensional DNA microarray gene expression data analysis. Elucidating the cluster properties of these multidimensional data are often complex. Patterns, hypotheses on the relationships, and ultimately of the function of the gene can be analyzed and visualized by non-linear ...

Analysis of Gene Expression Discretization Techniques in Microarray Biclustering

2017
Gene expression biclustering analysis is a commonly used technique to see the interaction between genes under certain experiments or conditions. More specifically in the study of diseases, these methods are used to compare control and affected data in order to identify the involved or relevant genes.

MOLECULAR TECHNIQUES FOR THE ANALYSIS OF SOIL MICROBIAL PROCESSES: FUNCTIONAL GENE ANALYSIS AND THE UTILITY OF DNA MICROARRAYS

Soil Science, 2003
Traditional methods for the analysis of soil processes are based on measuring and modeling the distribution of chemical compounds and determining their transformation rates. These approaches have formed the basis of our understanding of soil biogeochemical processes, and they have demonstrated the fundamental role of microbes in regulating these ...

mRNA Expression Analysis and Classification of Colonic Biopsy Samples Using Oligonucleotide and cDNA Microarray Techniques

Hungarian Medical Journal, 2008
A vastagbéldaganatok korai diagnosztikája, terápiája, követése napjainkban sem teljesen megoldott. Munkánk során a vastagbéldaganatok biomarker-vizsgálatát, génexpressziós elemzését és osztályozását végeztük. Munkacsoportunk vizsgálatai alapján megállapítható, hogy a biopsziás minták oligonukleotid microarray-vizsgálati módszere az Affymetrix minőségi ...
