As the number of the measurement target sensors continues to grow and complicated, and the original track data association algorithm is complexity of the target increases, the process of track association is gradually difficult to meet the actual demand, so it is important to further analyze the multiple target tracking data association algorithm. Machine learning has become a research hotspot in various fields in recent years. In the field of data association, machine learning algorithms can also be used to achieve the processing of track data. Machine learning algorithms can effectively improve the correct association rate compared to traditional methods. Firstly, the basic content of the track data association problem is described; secondly, two common types of research under the multiple target tracking data association problems based on machine learning are analyzed and summarized; after that, the future development trend is predicted given the current research status; finally, the overall research content is summarized.
