Abstract Classifier learning assumes that the training data and the testing data are independent and identically distributed. Due to the overly stringent assumption, erroneous sample recognition of classifiers for out-of-distribution examples is often caused. Therefore, thorough research on out-of-distribution(OOD) detection becomes paramount. Firstly, the definition of OOD detection and the relevant research are introduced. A comprehensive overview of supervised detection methods, semi-supervised detection methods, unsupervised detection methods and outlier exposure detection methods is provided according to the difference of network training methods. Then, the existing OOD detection methods are summarized from the aspect of three key technologies: neural network classifiers, metric learning and deep generative models. Finally, research trends of OOD detection are discussed.

Key words： Machine Learning Deep Learning Out-of-Distribution(OOD) Detection Image Recognition
