Topological Maps of Kohonen Self-Organization (SOM) Applied To the Study of Sediments Contaminated With Heavy Metals
Journal Title: American journal of Engineering Research - Year 2016, Vol 5, Issue 4
Abstract
This work aims to apprehend the history of the metallic pollution in the retaining of the Sidi Chahed dam since its inception in 1997 through the sediments of 4 carrots levied the level the embouchures the main wadis (Wadi Mikkes, embouchure Wadi Mikkes, embouchure Wadi Lmallah and embouchure Wadi Jajouiyne). The classification of data by self-organizing maps Kohonen allowed understanding and visualizing the spatial and temporal distribution of samples. Principal component analysis (PCA) and hierarchical classification of SOM maps (SOM AHC) were also used for validating the obtained results. Correlations and relationships between the samples and the variables can be easily visualized using the viewing of planes of components of the self-organizing map. The results have highlighted the dependencies between the different metal elements and the classification of studied sediments into four classes into function of four stations coring and their pollution levels.
