Researchers have developed a new method to explain the predictions of Temporal Graph Networks (TGNs) by focusing on their memory modules. This approach utilizes a topology attribution tree to assess the influence of neighbors and their historical data, and a memory backtracking tree to quantify how past events shape node memory. The method, which applies LRP in TGNs and includes optimization objectives for identifying important events, has demonstrated faithful explanations and superior performance over existing baselines across various temporal graph datasets and tasks, including node property prediction, link prediction, and graph classification.
