Abstract

The out-of-distribution detection task is a hot problem in image processing, aiming to detect samples that have never been trained by a deep learning model, thus ensuring the safety of the model for use in real-world environments. Currently widely used out-of-distribution detection methods suffer from single-layer representation dependence and poor adaptability. In order to overcome these problems, this paper proposes a Multilevel Feature Detection Network (MFDNet), which detects different representations of different out-of-distribution examples with the help of intermediate layer features. At the same time, a grouping module is introduced in the final layer of MFDNet to help the model reduce the decision boundaries between categories and enhance the adaptability of the model. A comparison with several common out-of-distribution detection methods on the out-of-distribution evaluation datasets validates that MFDNet can effectively handle the out-of-distribution detection task.
