Improving the diversity of auxiliary outlier data used during training is crucial for enhancing the generalization ability of out-of-distribution (OOD) detection methods in machine learning.
Synthesizing high-quality, near out-of-distribution images using a novel method called NCIS, which leverages diffusion models and non-linear class-conditional distributions, significantly improves a classifier's ability to detect out-of-distribution samples.
COOD는 사전 훈련된 비전-언어 모델(VLM)을 활용하여 복잡한 다중 레이블 설정에서 추가적인 재훈련 없이 OOD 샘플을 효과적으로 탐지하는 제로샷 프레임워크입니다.
COOD is a novel zero-shot framework that leverages pre-trained vision-language models and a concept-based label expansion strategy to effectively detect out-of-distribution (OOD) samples in complex, multi-label image datasets.
現有的 Out-of-Distribution Detection 基準測試設定存在缺陷,因為它們沒有區分語義空間和共變量空間的偏移,導致某些 OOD 樣本無法被基於 ID 數據訓練的分類器識別。
The current definition of out-of-distribution (OOD) detection is flawed, making certain OOD testing protocols intractable for post-hoc methods. This paper proposes a more precise definition of "semantic shift" based on the training data, introducing the concepts of "Semantic Space" and "Covariate Space" to clarify the limitations of post-hoc OOD detection and define a "Tractable OOD" setting.
This research paper introduces ASCOOD, a novel method for improving out-of-distribution (OOD) detection in deep learning models by addressing the challenges posed by spurious correlations in training data and the subtle differences in fine-grained classification tasks.
This research paper introduces a novel method for unsupervised out-of-distribution (OOD) detection in computer vision, leveraging the power of diffusion models for reconstructing semantic features extracted from multiple layers of image data.
This paper proposes a novel method called CATEX, which leverages the power of vision-language models like CLIP to improve out-of-distribution (OOD) detection in image classification. CATEX introduces hierarchical context descriptions - perceptual and spurious contexts - to define precise category boundaries, enabling the model to better distinguish between in-distribution and OOD samples, even in category-extended scenarios.
