What is attention misalignment in translation?

It's a metric spotting when an AI translator's focus drifts from source to target words, signaling likely hallucinations or low-confidence inventions.

Does detecting translation hallucinations require extra training?

Nope — just analyze existing attention weights post-inference. Runs cheap on any hardware.

Will attention-based uncertainty work for other AI tasks?

Absolutely promising for summarization or QA, where focus glitches predict errors too.
