Process of creating a GenModel. GenModel is created by dividing the sequence into equal sized segments and evaluating word frequency distributions, called Numerical Summarization Vectors (NSVs), for each segment. This example shows word size of 3. The model is created by comparing each new segment's frequency profile with existing clusters. The segment is assigned to the closest cluster that is within a threshold distance, if no such cluster is available, a new cluster is created with the segment as the first member. Here NSV3 and NSV4 are close enough to be assigned to the same cluster.
