Abstract: In a method and apparatus for automated inspection, an image is acquired of an object under inspection and a difference image is generated showing the difference between the acquired image and a reference image of a defect-free object of the same type. Characteristics of the difference image, or detected isolated regions of the difference image, are passed to an automated defect classifier to classify defects in the object under inspection. The characteristics of the difference image may be pixels of the difference image or features determined therefrom. The features may be extracted using a neural network, for example. The automated defect classifier is trained using difference images and may be further trained, in operation, based on operator classifications and using simulated images of defects identified by an operator.

Abstract: An online concierge system receives orders from users identifying items and a warehouses from which the items are obtained. The online concierge system displays groups of one or more orders to shoppers, allowing a shopper to select a group of orders for fulfillment. When selecting groups of orders to display to shoppers, the online concierge system accounts for costs for fulfilling different groups and displays groups having costs satisfying one or more criteria, while maintaining one or more restrictions on times to fulfill orders. The online concierge system trains a selection prediction model to predict an amount of time for a shopper to select a group of orders and determines an estimated fulfillment time for the group from the predicted amount of time. Accounting for the predicted selection time allows the online concierge system to identify a larger number of groups for which costs of fulfillment are determined.
