Identifying control\u2010important nodes is a fundamental challenge in temporal network controllability, as effective control depends not only on network topology but also on the timing and sequence of connections, making the detection of critical control nodes essential for reducing control cost and improving robustness. In this paper, we propose a novel learning\u2010based framework that formulates the identification of control\u2010important nodes as a node classification problem on temporal networks and addresses it using a temporal graph transformer neural network. The proposed method integrates spatial attention to capture structural dependencies within each temporal snapshot and temporal attention to model the evolution of node influence across time, followed by a spatiotemporal feature fusion mechanism that generates expressive node representations. Based on these representations, nodes are classified into critical, ordinary, and redundant categories without explicitly enumerating all possible minimum driver node sets or temporal matchings. Experimental evaluations on both synthetic and real\u2010world temporal networks demonstrate that the proposed approach achieves high accuracy, robustness, and scalability compared with existing graph\u2010based and temporal learning methods. The results confirm that the model effectively captures time\u2010respecting control patterns and provides an efficient and interpretable solution for identifying control\u2010important nodes, thereby bridging temporal network controllability theory with modern transformer\u2010based graph learning techniques.<\/jats:p>","DOI":"10.1155\/cplx\/8861757","type":"journal-article","created":{"date-parts":[[2026,4,22]],"date-time":"2026-04-22T05:40:05Z","timestamp":1776836405000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Detection
