Non-Stationarity in the Embedding Space of Time Series Foundation Models
★★★★★
significance 2/5
This research paper investigates how non-stationarity affects the embedding spaces of time series foundation models. The authors examine how mean shifts, variance changes, and linear trends impact the detectability of signals within these models.
Why it matters
Understanding embedding stability is critical for ensuring foundation models remain reliable as real-world data distributions shift over time.
