Breaking Predictions Is Not Enough: Specified-Foil Counterfactuals for Temporal Graphs

The paper introduces Specified-Foil Counterfactuals for temporal graphs, a method that seeks low‑cost past‑event interventions to make a user‑specified alternative outcome the top prediction. It uses trace‑guided search to compare completed executions of the original prediction with reconstructed incomplete executions of the foil, mapping differences to operations such as DELETE, INSERT, REWIRE, RELABEL, and SHIFT, and then verifies the foil through exact replay. Experiments on continuous‑time dynamic graphs and temporal knowledge graphs show that the approach retains most greedy successes while dramatically reducing predictor evaluations and achieving the specified foil in a majority of cases.

BridgeMem: Causal Dyadic Transition Residuals for Temporal Knowledge Graph Forecasting

BridgeMem is a new method for temporal knowledge graph forecasting that focuses on pair‑specific transition evidence, adding a residual correction to the log scores of a frozen full‑vocabulary forecaster. It retrieves and encodes prior events between a query actor and candidate, converting them into a likelihood‑ratio correction via a support‑adaptive empirical‑Bayes reader. Across five benchmarks, BridgeMem outperforms nine baselines from 2021–2026, improving filtered MRR and Hits@{1,3,10} metrics by up to 0.0216.
