Figure 1From: Identifying and predicting social lifestyles in people’s trajectories by neural networksPreprocessing. The preprocessing stage from raw data to clustered trajectories. d is the cell size; A, B, C, D, and O are POIs (O is a POI outside the map); g is the number of trajectories (and days); gT is the number of unique trajectories, where each day is represented by a 24-hour trajectory; and N is the number of trajectory clustersBack to article page
