TWIG: A Time-Causal Wavelet Operator for Autoregressive Forecasting on Irregular Graphs

We introduce TWIG (Time-Causal Wavelet Operator for Irregular Graphs), a graph-native neural operator for autoregressive surrogate modeling on static irregular graphs. TWIG transforms each node history into causal multiscale temporal features that separate recent variation from progressively slower memory components, t...
