Retrieval Is Not Enough: Refreshing Memory for Frozen Time-Series Forecasters
נבאי זמני קפוא: תקיפה מחדש של זיכרון. פרקטיקה חדשה של תקיפה מחדש של זיכרון, FreshCast, שמשפרת את נבאי הזמן-סדר.
תקציר מקורי באנגליתarXiv:2610.07834v2 Announce Type: replace Abstract: Retrieval-augmented time-series forecasting uses the continuations of historical segments similar to the current context as references for a forecaster. Most existing methods build the retrieval memory once from the training segment, leaving observations revealed after deployment unavailable as references, and generally do not calibrate how much the retrieved information should influence a frozen forecaster. We identify two key determinants of retrieval utility for a frozen forecaster: whether the history still reflects the current state, and whether the correction it induces aligns with the forecaster's residual errors, an alignment that can shift between validation and deployment when the memory becomes stale. We propose FreshCast, a pl
