Researchers have developed Fi-ImageNet-1k, a new dataset designed to challenge out-of-distribution (OOD) detection capabilities in AI models. This dataset is derived from ImageNet-1k validation images that were reannotated and found to not belong to any ImageNet-1k class. Expert human annotators, aided by multimodal large language models (MLLMs), vision-language models (VLMs), and reverse image search, identified images that could be assigned a specific class outside the original ImageNet-1k label space. The resulting Fi-ImageNet-1k contains 655 images across 522 classes and is significantly more difficult than existing OOD datasets, with current state-of-the-art methods failing to achieve a false positive rate below 51% at a 95% true positive rate.
