WebPage topic: "Entropic Issues in Likelihood-Based OOD Detection - arXiv". Created by: Keith Haynes. Language: english. WebMay 9, 2024 · Intuitively, OOD data should result in network predictions with high entropy, corresponding to a state of uncertainty in which all possible outputs are assigned uniform probability. On the other hand, network predictions for data that is understood well should have low entropy, as the model predicts the correct class with high confidence if it ... crear dataframe python pandas

Web3.2 Likelihood Ratios for OOD Detection Cancel Out the Entropy The above analysis suggests that performing likelihood-based OOD detection without somehow accounting for the entropy of incoming data is problematic. On the other hand, OOD detection methods based on likelihood ratios have recently demonstrated strong performance [24, 28, 27]. WebSep 9, 2024 · We assessed the effect of holdout class granularity and found that the softmax-based OOD heuristics (MSP, ODIN, and prediction path probability) are most sensitive to fine-grain OOD samples whereas MOS and path entropy metrics perform best on coarse-grain OOD as shown in table 1. Also, we find that outlier exposure improves … Webtest OOD samples get a lower likelihood proba-bility than the ID data. For example, Maximum Softmax Probability (MSP) (Hendrycks and Gim-pel,2024) detects a test query as OOD if its max softmax probability is lower than a fixed thresh-old. However, all these models make a strong distributional assumption of the practical OOD dm with glaucoma icd
