Initially, the RandomForest model achieved a score of 82.6% by utilizing the top 5000 tf-idfs as features over 91 days of treets. This is with the model predicting an increase in daily_avg 100% of the time However, by simply looking at analysis of the Department of Health data, you can see that 80.2% of the days in our data set contributed to an increase in daily average, in the first place. Manually lowering the probability threshold to .25 for 'decrease' results in slighlty more resolution in our confusion matrix.
