AI is subtly growing and becoming vital in our daily life. Particularly, Self-Organizing Map (SOM), one of the major branches of AI, is a useful tool for clustering data and has been applied successfully and widespread in various aspects of human life such as psychology, economic, medical and technical fields like mechanical, construction and geology. In this paper, the primary purpose of the authors is to introduce SOM algorithm and its practical applications in geology and construction. The results are classification of rock facies versus depth in geology and clustering two sets of construction prices indices and building material costs indice. Index Terms— Self Organizing Map, Hierarchical Clustering, Geology, Well logging, Construction Economics. 1 INTRODUCTION S OM (Self-Organizing Map) is a result of Unsupervised learning algorithm – this algorithm bases on the structure of input data in order to reduce the quantity of data dimensions or to cluster this data into different sections without precise result at the output [1, 2]. SOM’s result is a clustering map including a number of nodes (cells) with similar characteristic into the same field or section [2, 3]. The biggest advantage of SOM is that it illustrates visually multiManuscript Received on August 7th, 2017.
