We explored text complexity's impact on model training. Using different models, tasks, and complexity measures, we divided the training set into subsets and studied their effect on accuracy. Our result shows that (1) LSTM is more sensitive to complexity than BERT; (2) UID is a promising text complexity measure; (3) Training on low-complexity data generalizes well to high-complexity tests, but not vice versa; (4) Training from easy to hard reduces steps by 30%-50% without accuracy loss, compressing training time effectively.
