A method for detecting abnormal symptoms of a vehicle based on self-supervised learning by using pseudo normal data may comprise the steps of: obtaining normal data generated in a vehicle; preprocessing the obtained normal data; generating pseudo normal data by inputting the preprocessed normal data into a pre-trained first neural network model; training a second neural network model on the basis of the generated pseudo normal data; and detecting abnormal symptoms of the vehicle by inputting the data generated in the vehicle into the trained second neural network model.
Un procédé de détection de symptômes anormaux d'un véhicule basés sur un apprentissage auto-supervisé à l'aide de données pseudo-normales peut comprendre les étapes consistant à : obtenir des données normales générées dans un véhicule ; prétraiter les données normales obtenues ; générer des données pseudo-normales par entrée des données normales prétraitées dans un premier modèle de réseau neuronal préalablement entraîné ; entraîner un second modèle de réseau neuronal sur la base des données pseudo-normales générées ; et détecter des symptômes anormaux du véhicule par entrée des données générées dans le véhicule dans le second modèle de réseau neuronal entraîné.
