In this task, you are given the abstract of a research paper. Your task is to generate a summary of this abstract. Your summary should not be very short, but it's better if it's not more than 30 words.
Q: We propose an implementation of GNN that predicts and imitates the motion be- haviors from observed swarm trajectory data. The network's ability to capture interaction dynamics in swarms is demonstrated through transfer learning. We finally discuss the inherent availability and challenges in the scalability of GNN, and proposed a method to improve it with layer-wise tuning and mixing of data enabled by padding.
A:
Improve the scalability of graph neural networks on imitation learning and prediction of swarm motion
