AI Technical Summary

Problems solved by technology

Since sensor data from different operators (e.g., public institutions and private companies) may contain sensitive privacy information, current centralized machine learning methods cannot acquire traffic from different operators (e.g., public institutions and private companies) due to data privacy concerns. traffic data, resulting in the inability to guarantee the accuracy of traffic flow forecasting

Abstract

The invention discloses a method for predicting traffic flow, which is used for predicting the terminal and the cloud, wherein the method for predicting the traffic flow of the terminal includes: obtaining a local initial model from the cloud; obtaining source traffic flow data and target traffic flow data; using The source traffic flow data and the target traffic flow data train the local initial model to obtain target shared data; transmit the target shared data to the cloud, so that the cloud can use the target shared data to update the The global update model is obtained from the local initial model; the global update model is obtained to predict traffic flow. The present invention can accurately predict traffic flow under the condition of not compromising privacy protection constraints.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a traffic flow prediction method, device, equipment and computer storage medium. Background technique [0002] Traffic Flow Prediction (TFP) is to use historical traffic flow data to predict future traffic flow, so as to provide traffic flow information that people need. Contemporary urban residents, taxi drivers, commercial sectors, and government agencies all strongly demand accurate and timely traffic flow information, because these road users can use this information to alleviate traffic congestion, properly control traffic lights, and improve traffic efficiency. People can also use traffic flow information to make better travel plans. [0003] In traffic flow forecasting, centralized machine learning methods are usually trained on enough sensor data to accurately predict traffic flow, such as data from mobile phones, cameras, radar, etc. Since sensor...
