Abstract: A user may place an item at an inventory location in an incorrect location, such as the wrong lane on the shelf. An untidy score is generated that is indicative of whether an item is where it is supposed to be. A correct item verification (CIV) score is determined that is indicative of how similar the returned item is to the type of item that is supposed to be stored at that location. An invalid item recognition (IIR) score is determined that is indicative of similarity of the returned item to a set of items associated with the user, that set excluding the item that is supposed to be stored at that location. The CIV and the IIR are combined to generate an untidy score. Based on the untidy score, someone may be dispatched to clean up the inventory location.
