Fig. 3From: Complex temporal topic evolution modelling using the Kullback-Leibler divergence and the Bhattacharyya distanceThe distributions of the number of connections leading from topics in our topic relatedness graph inferred using the a BHD and the b KLD using the CDF pruning threshold of ζ=0.9. The axis x, y, and z respectively correspond to time (i.e. epochs), number of branches leading from a topic, and the corresponding number of topicsBack to article page
