Out-of-distribution (OOD) detection has attracted a large amount of attention from the machine learning research community in recent years due to its importance in deployed systems. Most of the previous studies focused on the detection of OOD samples in the multi-class classification task. However, OOD detection in the multi-label classification task remains an underexplored domain. In this research, we propose YolOOD - a method that utilizes concepts from the object detection domain to perform OOD detection in the multi-label classification task. Object detection models have an inherent ability to distinguish between objects of interest (in-distribution) and irrelevant objects (e.g., OOD objects) on images that contain multiple objects from different categories. These abilities allow us to convert a regular object detection model into an image classifier with inherent OOD detection capabilities with just minor changes. We compare our approach to state-of-the-art OOD detection methods and demonstrate YolOOD's ability to outperform these methods on a comprehensive suite of in-distribution and OOD benchmark datasets.

我们介绍了关于多语言信息访问（MIA）2022共享任务的研讨会的结果，评估了16种类型上多样性的语言中的跨语性开放回程答案（QA）系统。在此任务中，我们在14种类型上多样化的语言中调整了两个大规模的跨语性开放式质疑QA数据集，并使用了2种代表性不足的语言中的新注释的开放式QA数据：Tagalog和Tamil。四个团队提交了他们的系统。利用迭代开采的最佳系统是不同的负面示例和较大的预审慎模型达到32.2 F1，表现优于我们的基线4.5分。第二最佳系统使用实体感知的上下文化表示文档检索，并在泰米尔语（20.8 F1）方面取得了重大改进，而其他大多数系统的得分几乎为零。

我们提出了一种基于语境化嵌入的单词和实体的全局实体消除歧义（ED）模型。我们的模型基于BERT和培训我们的新培训任务，使模型能够捕获基于Word的本地和基于实体的全局上下文信息。该模型解决了ED作为序列决策任务，有效地使用两种类型的上下文信息。我们在五个标准ED数据集中实现了新的最先进结果：AIDA-CONLL，MSNBC，AQUAINT，ACE2004和WNED-Wiki。我们的源代码和培训的模型检查点可在https://github.com/studio-ousia/luke获得。
