Abstract: The present disclosure relates to a fashion recommendation system that employs a task-guided learning framework to jointly train a visually-aware personalized preference ranking network. In addition, the fashion recommendation system employs implicit feedback and generated user-based triplets to learn variances in the user's fashion preferences for items with which the user has not yet interacted. In particular, the fashion recommendation system uses triplets generated from implicit user data to jointly train a Siamese convolutional neural network and a personalized ranking model, which together produce a user preference predictor that determines personalized fashion recommendations for a user.

Abstract: An apparatus and method for facilitating the removal of layers from a die for an integrated circuit while maintaining the planarity of the surface of the die by avoiding rounding the corners and other edges of the die. A pocket is created in a sacrificial material, such that when the die is inserted into the pocket the edges of the die are contiguous with the walls of the pocket and a top surface of the die is coplanar with a top surface of the pocket. The sacrificial material may be the same material as the die. An adhesive substance is placed in the pocket, and the die is inserted into the pocket and against the adhesive substance which aids in retaining the die in the pocket. The layers may then be removed from the die and the sacrificial material around the die without rounding the edges of the die.
