Provided is a neural architecture search method based on knowledge distillation, which trains a student network using knowledge acquired from a teacher network and searches a target neural network. The neural architecture search method may include the steps of: (a) extracting an image feature map from a learning model of the student network; (b) calculating a loss function by comparing an image feature map extracted from a learning model of the teacher network to the image feature map extracted in the step (a); (c) selecting a block whose capacity is to be increased and a block whose capacity is to be decreased, for each learning model block of the student network, based on the loss function; and (d) deciding a candidate learning model of the student network according to the block architecture selected in the step (c).

Neural architecture search method based on knowledge distillation

The present invention relates to a heat dissipating device. More particularly, the present invention relates to a heat dissipating device in which an air flow is directed to a heat dissipating member by flapping a blade for making a driving unit and a device therefor small, improving heat dissipating efficiency and reducing noise therefrom.

Heat dissipating device

The present invention relates to a heat dissipating device. More particularly, the present invention relates to a heat dissipating device in which an air flow is directed to a heat dissipating member by alternating rotation of blades within a preset range of angle for making a driving unit and a device thereof smaller, and improving heat dissipating efficiency.

There is provided an actuator, an optical device, and an optical recording/reproducing apparatus. In the optical device, a first lens is fixed in an optical axis and a second lens, a movable member is supported by a shaft and slidable in an optical axis direction, and a second lens is formed on the movable member. The movable member is moved by interaction between a coil and a magnet.

Actuator, optical device, and optical recording/reproducing apparatus

The present invention provides an optical pickup actuator, in which a pair of lenses, e.g., BD lens and DVD lens, are loaded on one pickup to record/reproduce information on/from optical discs having various write capacities such as BD (Blu-ray disc), CD, DVD and the like, by which drive and system configurations can be simplified, and by which the facilitation of the system configuration and high sensitivity of the actuator are provided since there exist no sensitivity deviations of tracking and focusing between BD and CD or DVD actuators.

Optical pickup actuator

A spherical aberration compensation actuator and an optical pickup system are provided. The spherical aberration compensation actuator mounts an element for compensating a spherical aberration and operates to a single-axis direction on an optical path using electromagnetic force. The optical pickup system includes a laser diode, an object lens, a spherical aberration compensation actuator, an optical path changer, and an optical detector. The spherical aberration compensation actuator is installed on an optical path between the laser diode and the object lens and includes a lens holder having a spherical aberration compensation element for compensating a spherical aberration generated due to light passing through the object lens and operating in an optical-axis direction using electromagnetic force.
