| Abstract | The Self-Organizing Map (SOM) is a popular neural network model. The SOM
quantizes the data space formed by the training data and simultaneously performs a topology
preservation of the data space on a regular two-dimensional grid. The SOM also has an
excellent visualization capability including techniques to give an informative picture of the
data space, and techniques to compare data vectors or whole data sets with each other. The
SOM can be used for clustering, classification and modeling.
In this research, the SOM technique is applied on mapping the poverty data available
from countries. The world poverty map is based on multi-dimensions of poverty taking into
account a number of indicators. The map groups countries of similar levels of poverty
together, thus providing a visualization of structure of poverty. The data used for this study
was extracted from the World Development Indicators (WDI) published by the World Bank.
Ten poverty indicators were selected from the WDI, which related to quality of life, health,
education, and sanitation. The map in this study is obtained through self-organization cluster
poverty in 132 countries into 4 groups. Two-dimensional representations of the data are
presented showing the countries in each group. |
