• G02F 1/21 - Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics for the control of the intensity, phase, polarisation or colour by interference

Abstract

A bitstream reconstruction method and apparatus are provided. The method includes constructing an initial bitstream by rendering sound source information and geometry information within a reference radius from an initial location of a user accessing a virtual space into spatial audio, collecting location information according to a movement of the user within the virtual space, and reconstructing, based on a relationship between the reference radius and a movement radius identified according to the collected location information, the initial bitstream constructed by corresponding to the initial location of the user.

Abstract

Disclosed herein are a method for contrastive learning of a neural network for automatic data labeling and an apparatus for the same. The method includes generating transformed data samples for unlabeled input data samples corresponding to a batch size, detecting a positive sample (positive data) in the transformed data samples in consideration of the similarity between a single data sample for contrastive learning, among the input data samples, and each of the transformed data samples, and performing contrastive learning of a neural network based on the loss value of the positive sample.
