    Abstract: An electronic device and method are provided for generating abnormal data among learning data required for training a machine learning model. In addition, an electronic device and method are provided for a product anomaly detection using a model trained based on unsupervised learning. Embodiments may solve the data imbalance problem for learning by generating as much abnormal data as necessary based on normal data and provide an unsupervised learning-based anomaly detection method and electronic device that can provide stable performance without increasing the size or complexity of the artificial neural network and thus requiring relatively high-performance computing equipment.

    Abstract: A method for interpolating a missing value of the present invention comprises the steps of: collecting, by a data processing unit, a data set obtained by selecting an intact whole signal without a missing part from among a plurality of unit signals configuring a sensor signal; training, by a training unit, an interpolation network for interpolating a missing part in a missing signal having the missing part, wherein at least a part of a sensor signal is missing, by using the data set; receiving, by an interpolation unit, an input of the missing signal in which at least a part of the sensor signal is missing; and generating, by the interpolation unit, an interpolation signal by interpolating the missing part by using the interpolation network.

    Abstract: According to the present invention, a method for continuous learning of object anomaly detection and state classification model includes acquiring, by a detection and classification apparatus, information about a medium of anomaly detection from an inspection target; generating, by the detection and classification apparatus, an input value, which is a feature vector matrix including a plurality of feature vectors, from the medium information; deriving, by the detection and classification apparatus, a restored value imitating the input value through a detection network learned to generates the restored value for the input value; determining, by the detection and classification apparatus, whether a restoration error indicating a difference between the input value and the restored value is greater than or equal to a previously calculated reference value; and storing, by the detection and classification apparatus, the input value as normal data upon determining that the restoration error is less than the reference value.
