The number of international benchmarking competitions is steadily increasing in various fields of machine learning (ML) research and practice. So far, however, little is known about the common practice as well as bottlenecks faced by the community in tackling the research questions posed. To shed light on the status quo of algorithm development in the specific field of biomedical imaging analysis, we designed an international survey that was issued to all participants of challenges conducted in conjunction with the IEEE ISBI 2021 and MICCAI 2021 conferences (80 competitions in total). The survey covered participants' expertise and working environments, their chosen strategies, as well as algorithm characteristics. A median of 72% challenge participants took part in the survey. According to our results, knowledge exchange was the primary incentive (70%) for participation, while the reception of prize money played only a minor role (16%). While a median of 80 working hours was spent on method development, a large portion of participants stated that they did not have enough time for method development (32%). 25% perceived the infrastructure to be a bottleneck. Overall, 94% of all solutions were deep learning-based. Of these, 84% were based on standard architectures. 43% of the respondents reported that the data samples (e.g., images) were too large to be processed at once. This was most commonly addressed by patch-based training (69%), downsampling (37%), and solving 3D analysis tasks as a series of 2D tasks. K-fold cross-validation on the training set was performed by only 37% of the participants and only 50% of the participants performed ensembling based on multiple identical models (61%) or heterogeneous models (39%). 48% of the respondents applied postprocessing steps.

The security of artificial intelligence (AI) is an important research area towards safe, reliable, and trustworthy AI systems. To accelerate the research on AI security, the Artificial Intelligence Security Competition (AISC) was organized by the Zhongguancun Laboratory, China Industrial Control Systems Cyber Emergency Response Team, Institute for Artificial Intelligence, Tsinghua University, and RealAI as part of the Zhongguancun International Frontier Technology Innovation Competition (https://www.zgc-aisc.com/en). The competition consists of three tracks, including Deepfake Security Competition, Autonomous Driving Security Competition, and Face Recognition Security Competition. This report will introduce the competition rules of these three tracks and the solutions of top-ranking teams in each track.

多年来,Yolo系列一直是有效对象检测的事实上的行业级别标准。尤洛社区(Yolo Community)绝大多数繁荣,以丰富其在众多硬件平台和丰富场景中的使用。在这份技术报告中,我们努力将其限制推向新的水平,以坚定不移的行业应用心态前进。考虑到对真实环境中速度和准确性的多种要求,我们广泛研究了行业或学术界的最新对象检测进步。具体而言,我们从最近的网络设计,培训策略,测试技术,量化和优化方法中大量吸收了思想。最重要的是,我们整合了思想和实践,以在各种规模上建立一套可供部署的网络,以适应多元化的用例。在Yolo作者的慷慨许可下,我们将其命名为Yolov6。我们还向用户和贡献者表示热烈欢迎,以进一步增强。为了了解性能,我们的Yolov6-N在NVIDIA TESLA T4 GPU上以1234 fps的吞吐量在可可数据集上击中35.9%的AP。 Yolov6-S在495 fps处的43.5%AP罢工,在相同规模〜(Yolov5-S,Yolox-S和Ppyoloe-S)上超过其他主流探测器。我们的量化版本的Yolov6-S甚至在869 fps中带来了新的43.3%AP。此外,与其他推理速度相似的检测器相比,Yolov6-m/L的精度性能(即49.5%/52.3%)更好。我们仔细进行了实验以验证每个组件的有效性。我们的代码可在https://github.com/meituan/yolov6上提供。

在本文中,我们提出了一个紧密耦合的视觉惯性对象级多效性动态大满贯系统。即使在极其动态的场景中,它也可以为摄像机姿势,速度,IMU偏见并构建一个密集的3D重建对象级映射图。我们的系统可以通过稳健的传感器和对象跟踪,可以强牢固地跟踪和重建任意对象的几何形状,其语义和运动的几何形状,其语义和运动的几何形状,并通过逐步融合相关的颜色,深度,语义和前景对象概率概率。此外,当对象在视野视野外丢失或移动时,我们的系统可以在重新观察时可靠地恢复其姿势。我们通过定量和定性测试现实世界数据序列来证明我们方法的鲁棒性和准确性。

用于预培训语言模型的自我监督学习的核心包括预训练任务设计以及适当的数据增强。语言模型中的大多数数据增强都是独立于上下文的。最近在电子中提出了一个开创性的增强,并通过引入辅助生成网络(发电机)来实现最先进的性能,以产生用于培训主要辨别网络(鉴别者)的上下文化数据增强。然而,这种设计引入了发电机的额外计算成本,并且需要调整发电机和鉴别器之间的相对能力。在本文中,我们提出了一种自增强策略(SAS),其中单个网络用于审视以后的时期的培训常规预训练和上下文化数据增强。基本上,该策略消除了单独的发电机,并使用单个网络共同执行具有MLM(屏蔽语言建模)和RTD(替换令牌检测)头的两个预训练任务。它避免了寻找适当大小的发电机的挑战,这对于在电子中证明的性能至关重要,以及其随后的变体模型至关重要。此外,SAS是一项常规策略,可以与最近或将来的许多新技术无缝地结合,例如杜伯塔省的解除关注机制。我们的实验表明,SAS能够在具有相似或更少的计算成本中优于胶水任务中的电磁和其他最先进的模型。

Natural Language Processing (NLP) has been revolutionized by the use of Pre-trained Language Models (PLMs) such as BERT. Despite setting new records in nearly every NLP task, PLMs still face a number of challenges including poor interpretability, weak reasoning capability, and the need for a lot of expensive annotated data when applied to downstream tasks. By integrating external knowledge into PLMs, \textit{\underline{K}nowledge-\underline{E}nhanced \underline{P}re-trained \underline{L}anguage \underline{M}odels} (KEPLMs) have the potential to overcome the above-mentioned limitations. In this paper, we examine KEPLMs systematically through a series of studies. Specifically, we outline the common types and different formats of knowledge to be integrated into KEPLMs, detail the existing methods for building and evaluating KEPLMS, present the applications of KEPLMs in downstream tasks, and discuss the future research directions. Researchers will benefit from this survey by gaining a quick and comprehensive overview of the latest developments in this field.
