Abstract: This application relates to an active compensating device. In one aspect, the active compensating device includes two or more high current paths through which a second current supplied by a second device is transmitted to a first device, and a sensing unit sensing the first current on the high current paths and generating an output signal corresponding to the first current. The device may also include an amplifying unit amplifying the output signal of the sensing unit to generate an amplified current and a compensating unit generating a compensation current based on the amplified current and allowing the compensation current to flow to each of the two or more high current paths. The device may further include a first anti-disturbance unit connected in parallel to output terminals of the sensing unit, and a second anti-disturbance unit connected in parallel to input terminals of the compensating unit.

Abstract: Disclosed is a device for lightening an artificial intelligence-based generative model including a memory that stores data for lightening the artificial intelligence-based generative model and a processor that perform operations related to lighten the generative model. The processor assigns a randomly initialized score(s) to each of weights for a dense network based on an edge-popup algorithm, finds a random subnetwork, sorts the assigned scores in each forward path, and updates the scores using backpropagation, while leaving a weight with a preset top k % score.
