Estimating the Concrete Compressive Strength Using Hard Clustering and Fuzzy Clustering Based Regression Techniques
Input: : the number of clusters, : a data set containing objects. | Output: A set of clusters. | Method: | (1) arbitrarily choose objects from as the initial cluster centers; | (2) repeat | (3) (re)assign each object to the cluster to which the object is the most similar, | based on the mean value of the objects in the cluster; | (4) update the cluster means, that is, calculate the mean value of the objects for each cluster; | (5) until no change; |
