Title:
ANOMALY DETECTION DEVICE USING NEURAL NETWORK LEARNED USING HETEROGENEOUS LOSS FUNCTION
Document Type and Number:
WIPO Patent Application WO/2024/071728
Kind Code:
A1
Abstract:
An anomaly detection device is disclosed. The anomaly detection device using a heterogeneous loss function, according to one embodiment, comprises: a receiver for receiving data from which normality or anomaly is to be detected; and a processor for detecting whether an anomaly exists in the data, by inputting the data into a pre-learned neural network, wherein the pre-learned neural network can be learned through a heterogeneous loss function calculated using a gradient parameter determined on the basis of an anomaly score.
