The present invention provides a device, a method, a manufacturing method for a device, and a manufacturing method for an integrated circuit. The purpose of the present invention is to provide a device for a student-teacher transfer learning network using a knowledge bridge and a method thereof. The device includes: a teacher network; a student network; multiple knowledge bridges between the teacher network and the student network; and a loss function device connected to the multiple knowledge bridges and the student network. Each of the multiple knowledge bridges provides a hint related to a function to be learned. The hint includes a mean square error. The manufacturing method for a device includes: a step of training the teacher network; a step of providing the hint to the student network by the multiple knowledge bridges between the teacher network and the student network; and a step of determining the loss function based on the output of the student network and multiple knowledge bridges.;COPYRIGHT KIPO 2019
