Fig. 5

Illustration of the discovery of spatial directions using pairs of groups of users identified with different issues. Users expressing support for Biden or Trump are shown in blue and red. The direction shown in the figure corresponds to the normal to the decision boundary of a multivariate logistic regression model trained to separate these two groups in the latent space computed using the follower graph. Precision, recall, and F1 metrics for this classification are provided for this model, as well as the density of position of these two groups in the spatial direction defined by the normal
