Abstract
A method for determining an estimated time of arrival (ETA) includes receiving a start location and a destination from a user device via a network. The method also includes obtaining a machine learning model for determining an ETA, which is generated according to a process including: obtaining historical data related to an on-demand service order; determining a high-dimensional sparse feature based on the historical data; and determining a machine learning model based on the high-dimensional sparse feature. The method further includes determining an ETA for a target route based on the machine learning model, the start location, and the destination, and transmitting the determined ETA to the user device via the network.
