Abstract: Disclosed herein are a method and apparatus for encoding/decoding a deep neural network. According to the present disclosure, the method for decoding a deep neural network may include: in a plurality of layers of the deep neural network, entropy decoding quantization information for a current layer; performing dequantization on the current layer; and obtaining a plurality of layers of the deep neural network. At least one of global quantization and local quantization is performed on the current layer.

Abstract: The present invention relates to a power generation system using a vehicle. The power generation system includes: a vehicle, such as an automobile, a train, an airplane, and an escalator, for carrying people or freight; a movement route, such as a road, a railroad, and a runway, formed so that the vehicle can move thereon; and a power generation unit including a magnetic force generation portion and a magnetic force receiving portion alternatively installed in the vehicle and the movement route, and configured to generate electric energy using electromagnetic induction occurring due to relative movement between the magnetic force generation portion and the magnetic force receiving portion according to movement of the vehicle.

Abstract: Provided is an electricity generating elevator, which includes a cage installed in a shaft formed in a building in order to carry passengers or loads, a drive unit vertically moving the cage along the shaft, and an electricity generation unit including a coil section installed on the cage and a magnetic force generator that is installed in the shaft so as to face the coil section and provides a magnetic force to the coil section so as to generate an induced electromotive force according to a change in a position of the coil section while the cage moves up and down. Thereby, the electricity generating elevator includes the coil section attached to the cage and the magnetic force generator arranged in the shaft at a position facing the coil section, so that electric energy can be produced by the coil section according to a change in a position of the cage while the cage vertically reciprocates in the shaft, and the produced electric energy can be used as a power source for vertically moving the cage.
