FLatS: Principled Out-of-Distribution Detection with Feature-Based Likelihood Ratio Score (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for detecting out-of-distribution instances are empirical . state-of the-art methods for OOD detection are suboptimal since they only estimate in-distance density pout(x). |
| Approach: | They propose a method that measures the “OOD-ness” of a test case x through the likelihood ratio between out-distribution mathcal Pout and in-division mathcal Pin. |
| Outcome: | The proposed method improves existing methods on popular benchmarks and establishes a new SOTA on popular NLP benchmarks. |
