On the Powerfulness of Textual Outlier Exposure for Visual OoDDetection (Appendix) AAdditional experimental results

This section presents more comprehensive experimental results. A.1 Comparison with post-hoc methods We also compare the performance of our textual outlier method with post-hoc approaches, which are another prominent approach in OoD detection. We conducted comparisons with six widely used and recently proposed methods known for their detection performance (MSP [4], ODIN [8], Mahalanobis [7], Energy [10], ReAct [14], KNN [15]). All advanced baseline methods follow the original paper's settings. Among these methods, our textual outlier approach demonstrate the best performance, further emphasizing its effectiveness as demonstrated in Table 6.
