GITCO: Gated Inference-Time Context Optimization in TSFMs

In three linesGITCO optimizes input context at inference time for Time Series Foundation Models (TSFMs) to reduce degradation from anomalous patches. The three-component framework (Gate, Router, Critic) suppresses harmful patches without weight updates, achieving -1.95% MASE improvement on TimesFM 2.5 across 53 GIFT-Eval datasets.
