CLUSTERING PERFORMANCE VALIDATION OF KOHONEN SELF-ORGANIZING MAPSEXPONENTIAL DECAY AVERAGE RATE OF CHANGE (KSOM-EDARC) IMPLEMENTED ON FIRE DISASTER TWEETS

EDWIN F. GALUTIRA.

Abstract
Cluster validity assessment is one of the very important in the field of clustering analysis. The previous introduction of the Kohonen Self-organizing
Maps Exponential Decay Average Rate of Change (KSOM-EDARC) in the area of clustering paved the way for further exploration of its clustering
capability. This method is one of the recent enhancement of the algorithm, which enhances its learning rate decay function of using the Exponential
Decay Average Rate of Change (EDARC). Previous studies show that the clustering performance of the improved algorithm is better than the
conventional algorithm. The assessment was made using visual analysis and comparison on the learning rates of the improved algorithm against the
traditional KSOM. Hence, this paper provides a cluster validity assessment on the performance of the KSOM-EDARC and KSOM using three internal
validity index to validate the performance of the two algorithms further. Three internal validity index is used to validate the clustering results of the
algorithm. The Fire Disaster Tweets Dataset was used for clustering by the two algorithms. The average index values and the percentage difference
between the two algorithms were determined. Based on the results recorded by the indices of the two algorithms, the KSOM-EDARC produced well
separated and denser cluster results compared with the KSOM. The study concluded that KSOM-EDARC has better and improved performance and a
better solution than the traditional algorithm.

Key words: Clustering, Cluster Validity, Validity Index, Data Mining, Learning Rate
