Abstract: An audio signal encoding and decoding method using a neural network model, and an encoder and decoder for performing the same are disclosed. A method of encoding an audio signal using a neural network model, the method may include identifying an input signal, generating a quantized latent vector by inputting the input signal into a neural network model encoding the input signal, and generating a bitstream corresponding to the quantized latent vector, wherein the neural network model may include i) a feature extraction layer generating a latent vector by extracting a feature of the input signal, ii) a plurality of downsampling blocks downsampling the latent vector, and iii) a plurality of quantization blocks performing quantization of a downsampled latent vector.

Abstract: Disclosed is a service operation method for managing energy data for each tenant. More particularly, the service operation method monitors energy consumption consumed in a specific space that a tenant manager desires to manage using an individualized energy management service user interface (UI) according to a service development/production environment set by a manager terminal and visualizes a status of use of energy for each specific space from a monitoring result.
