A Generative Deep Learning Approach for Crash Severity Modeling with Imbalanced Data
Junlan Chen, Ziyuan Pu, Nan Zheng +3
Crash data is often greatly imbalanced, with the majority of crashes being non-fatal crashes, and only a small number being fatal crashes due to their rarity. Such data imbalance i…
