  • Publication number: 20200312350
    Abstract: A sound event detection method includes receiving a sound signal and determining and outputting whether a sound event is present in the sound signal by applying a trained neural network to the received sound signal, and performing post-processing of the output to reduce an error in the determination, wherein the neural network is trained to early stop at an optimal epoch based on a different threshold for each of at least one sound event present in a pre-processed sound signal. That is, the sound event detection method may detect an optimal epoch to stop training by applying different characteristics for respective sound events and improve the sound event detection performance based on the optimal epoch.

  • Patent number: 8459705
    Abstract: Provided is a door lock apparatus which is adopted in an electronic product to lock or release a door of the door lock apparatus. The door lock apparatus includes a rocker, a rocker supporting member, a door lock main body and a locking unit. The rocker rotates when the hook of the door enters or withdraws from the door lock apparatus, to be coupled with or separated away from the hook. A rocker hinge rod and a position fixing rode positioned in parallel to the rocker hinge rod are integrated into the rocker. The rocker supporting member is hinge-coupled with the rocker hinge rod to rotatably support the rocker, reciprocatingly moves in a direction in which the hook enters or withdraws when the rocker is rotated, and receives an elastic force from a first elastic member in the direction in which the hook enters.
