The predicted population in three data sets using population growth model. (a) Renren, the ground-truth value of the population size between 36th month and 60th month (as points) vs. the predicated value by the model (as dashed lines). (b) Twitter, the ground-truth value of the population size between 41th month and 51th month (as points) vs. the predicated value by the model (as dashed lines). (c) Gowalla, the ground-truth value of the population size between 15th month and 20th month (as points) vs. the predicated value by the model (as dashed lines).
