Abstract
This paper challenges the common assumption that drift must be detected through sequential analysis. The claim is that when the representation is rich enough, a single observation can contain the signal.
What it establishes
- Sequential analysis is not always necessary.
- High-dimensional deterministic features can expose drift instantly.
- The problem may be better understood as representation quality rather than sequence length.
Why it matters
If drift is instantaneous at the representation level, then monitoring systems can be both faster and conceptually simpler than many current approaches assume.
