Abstract: In accordance with an aspect of the present disclosure, there is provided an adversarial self-supervised learning method for an encoder. The method comprises selecting a target image of an original image for training from an image group included in a previously collected dataset; generating a noise image by combining the original image for training with noise using the original image for training and the target image; and training the encoder using the noise image and the original image for training.

Abstract: Disclosed is a random sampling-based collective classification method and system for Sybil account detection. A random sampling-based collective classification method performed by a collective classification system may include performing a first collective classification using training data; constructing sampled new training data by randomly extracting a portion of the entire nodes based on a label assigned to each node according to a result of performing the first collective classification; performing a second collective classification using the constructed new training data; and applying a posterior score difference of each node computed through the first collective classification and the second collective classification to a prior score of each node to be used for training data at a next iteration.
