TopoCast: A Topological Fidelity Framework for Evaluating Transformer-Based Time Series Forecasting
TopoCast, a topology-driven framework for evaluating structural fidelity in TSF, is proposed and dominant cycle overlap is introduced, a novel metric that maps persistent topological features to the temporal domain to assess whether dominant oscillatory patterns occur at the correct time points.
