| Summary:

In this article, we review recent machine learning methods used in
challenging particle identification of heavy-boosted particles at high-energy
colliders. Our primary focus is on attention-based Transformer networks. We
report the performance of state-of-the-art deep learning networks and further
improvement coming from the modification of networks based on physics insights.
Additionally, we discuss interpretable methods to understand network
decision-making, which are crucial when employing highly complex and deep
networks.
