GITCO: Gated Inference-Time Context Optimization in TSFMs
Researchers introduce GITCO, a lightweight inference-time optimization framework that improves Time Series Foundation Models (TSFMs) by identifying and suppressing anomalous patches without modifying model weights. The method achieves a 1.95% average improvement in forecast accuracy on TimesFM 2.5, addressing the critical problem of context poisoning where structurally irregular data segments degrade zero-shot prediction quality.
