How AI Stops Seeing Things That Aren’t There

Ever wondered why a smart camera sometimes describes a “red car” that isn’t in the picture? Scientists discovered that the AI’s “visual tokens” – tiny data pieces it extracts from an image – can become unsure, leading the system to imagine objects that don’t exist. Think of it like a blurry fingerprint: when the print is fuzzy, the detective might guess the wrong suspect. By spotting these fuzzy tokens early, researchers learned to “mask” them, much like covering a smudged spot on a photo, so the AI stops letting the uncertainty influence its description. The result? A much clearer, more trustworthy narration of what the camera actually sees. This simple tweak not only reduces the AI’s day‑dreaming but also works well with other imp…
