A comparison between the topic trend \(g_{k}(t)\) (blue in the left panels) and the popularity of posts (black in the right panels) over time in Reddit. The gray area represents the 95% confidence interval of the topic trend. Filled circles mark the days when the topic trend is significantly higher than zero for at least three consecutive days. The three examples are the same as those in Fig. 3
