The results of robustness experiments of scientists’ topic transition model in the knowledge space. a–b. A fine-grained Voronoi diagram of knowledge space with 258 subspaces and its predicting results of topic-transition models. c. The predicting results of topic-transition models under the experiment of randomizing papers’ coordinates. Grey dots and red box plots: Marking and estimating the measured flux between the Gravity or Radiation Model generated against the real flow. The white triangle-up marker corresponds to the mean number of predicted points in that bin. A blue line \(y=x\) lies in the plot as the benchmark
