Use time0 data (pre-campaign) to predict time1 data (7-14 days ahead). - model: gradient-boosted decision trees (light GBM) - left panel: simple bivariate correlation between time0 (x) and time1 (y) values - right panel: model-predicted time1 value (x) and observed time1 value (y) # Predict mean (quality) ![[lgbm_quality_mean_y.png]] # Predict sum (quality) ![[lgbm_quality_sum_y.png]] # Predict count (no. of tweets) ![[lgbm_quality_count_y.png]]
