本文关注的是将许多预训练的深神经网络（DNN）（称为检查点）排名，以将学习转移到下游任务。由于广泛使用了DNN，我们可能很容易从各种来源收集数百个检查站。他们中的哪个将最好的人转移到我们感兴趣的下游任务？为了彻底回答这个问题，我们建立了一个神经检查点排名基准（Neucrab），并研究一些直观的排名措施。这些措施是通用的，适用于不同输出类型的检查点，而无需知道如何对哪个数据集进行检查。它们还产生了低计算成本，使它们实际上有意义。我们的结果表明，检查点提取的特征的线性可分离性是可传递性的强烈指标。我们还达到了一种新的排名NLEEP，这在实验中带来了最佳性能。

There is a growing interest in developing unlearnable examples (UEs) against visual privacy leaks on the Internet. UEs are training samples added with invisible but unlearnable noise, which have been found can prevent unauthorized training of machine learning models. UEs typically are generated via a bilevel optimization framework with a surrogate model to remove (minimize) errors from the original samples, and then applied to protect the data against unknown target models. However, existing UE generation methods all rely on an ideal assumption called label-consistency, where the hackers and protectors are assumed to hold the same label for a given sample. In this work, we propose and promote a more practical label-agnostic setting, where the hackers may exploit the protected data quite differently from the protectors. E.g., a m-class unlearnable dataset held by the protector may be exploited by the hacker as a n-class dataset. Existing UE generation methods are rendered ineffective in this challenging setting. To tackle this challenge, we present a novel technique called Unlearnable Clusters (UCs) to generate label-agnostic unlearnable examples with cluster-wise perturbations. Furthermore, we propose to leverage VisionandLanguage Pre-trained Models (VLPMs) like CLIP as the surrogate model to improve the transferability of the crafted UCs to diverse domains. We empirically verify the effectiveness of our proposed approach under a variety of settings with different datasets, target models, and even commercial platforms Microsoft Azure and Baidu PaddlePaddle.

The findable, accessible, interoperable, and reusable (FAIR) data principles have provided a framework for examining, evaluating, and improving how we share data with the aim of facilitating scientific discovery. Efforts have been made to generalize these principles to research software and other digital products. Artificial intelligence (AI) models -- algorithms that have been trained on data rather than explicitly programmed -- are an important target for this because of the ever-increasing pace with which AI is transforming scientific and engineering domains. In this paper, we propose a practical definition of FAIR principles for AI models and create a FAIR AI project template that promotes adherence to these principles. We demonstrate how to implement these principles using a concrete example from experimental high energy physics: a graph neural network for identifying Higgs bosons decaying to bottom quarks. We study the robustness of these FAIR AI models and their portability across hardware architectures and software frameworks, and report new insights on the interpretability of AI predictions by studying the interplay between FAIR datasets and AI models. Enabled by publishing FAIR AI models, these studies pave the way toward reliable and automated AI-driven scientific discovery.

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.

Video paragraph captioning aims to generate a multi-sentence description of an untrimmed video with several temporal event locations in coherent storytelling. Following the human perception process, where the scene is effectively understood by decomposing it into visual (e.g. human, animal) and non-visual components (e.g. action, relations) under the mutual influence of vision and language, we first propose a visual-linguistic (VL) feature. In the proposed VL feature, the scene is modeled by three modalities including (i) a global visual environment; (ii) local visual main agents; (iii) linguistic scene elements. We then introduce an autoregressive Transformer-in-Transformer (TinT) to simultaneously capture the semantic coherence of intra- and inter-event contents within a video. Finally, we present a new VL contrastive loss function to guarantee learnt embedding features are matched with the captions semantics. Comprehensive experiments and extensive ablation studies on ActivityNet Captions and YouCookII datasets show that the proposed Visual-Linguistic Transformer-in-Transform (VLTinT) outperforms prior state-of-the-art methods on accuracy and diversity.

As an efficient way to integrate multiple distributed energy resources and the user side, a microgrid is mainly faced with the problems of small-scale volatility, uncertainty, intermittency and demand-side uncertainty of DERs. The traditional microgrid has a single form and cannot meet the flexible energy dispatch between the complex demand side and the microgrid. In response to this problem, the overall environment of wind power, thermostatically controlled loads, energy storage systems, price-responsive loads and the main grid is proposed. Secondly, the centralized control of the microgrid operation is convenient for the control of the reactive power and voltage of the distributed power supply and the adjustment of the grid frequency. However, there is a problem in that the flexible loads aggregate and generate peaks during the electricity price valley. The existing research takes into account the power constraints of the microgrid and fails to ensure a sufficient supply of electric energy for a single flexible load. This paper considers the response priority of each unit component of TCLs and ESSs on the basis of the overall environment operation of the microgrid so as to ensure the power supply of the flexible load of the microgrid and save the power input cost to the greatest extent. Finally, the simulation optimization of the environment can be expressed as a Markov decision process process. It combines two stages of offline and online operations in the training process. The addition of multiple threads with the lack of historical data learning leads to low learning efficiency. The asynchronous advantage actor-critic with the experience replay pool memory library is added to solve the data correlation and nonstatic distribution problems during training.

When reading a story, humans can rapidly understand new fictional characters with a few observations, mainly by drawing analogy to fictional and real people they met before in their lives. This reflects the few-shot and meta-learning essence of humans' inference of characters' mental states, i.e., humans' theory-of-mind (ToM), which is largely ignored in existing research. We fill this gap with a novel NLP benchmark, TOM-IN-AMC, the first assessment of models' ability of meta-learning of ToM in a realistic narrative understanding scenario. Our benchmark consists of $\sim$1,000 parsed movie scripts for this purpose, each corresponding to a few-shot character understanding task; and requires models to mimic humans' ability of fast digesting characters with a few starting scenes in a new movie. Our human study verified that humans can solve our problem by inferring characters' mental states based on their previously seen movies; while the state-of-the-art metric-learning and meta-learning approaches adapted to our task lags 30% behind.

语义分割是开发医学图像诊断系统的重要任务。但是，构建注释的医疗数据集很昂贵。因此，在这种情况下，半监督方法很重要。在半监督学习中，标签的质量在模型性能中起着至关重要的作用。在这项工作中，我们提出了一种新的伪标签策略，可提高用于培训学生网络的伪标签的质量。我们遵循多阶段的半监督训练方法，该方法在标记的数据集上训练教师模型，然后使用训练有素的老师将伪标签渲染用于学生培训。通过这样做，伪标签将被更新，并且随着培训的进度更加精确。上一个和我们的方法之间的关键区别在于，我们在学生培训过程中更新教师模型。因此，在学生培训过程中，提高了伪标签的质量。我们还提出了一种简单但有效的策略，以使用动量模型来提高伪标签的质量 - 训练过程中原始模型的慢复制版本。通过应用动量模型与学生培训期间的重新渲染伪标签相结合，我们在五个数据集中平均达到了84.1％的骰子分数（即Kvarsir，CVC-ClinicdB，Etis-laribpolypdb，cvc-colondb，cvc-colondb，cvc-colondb和cvc-300）和CVC-300）只有20％的数据集用作标记数据。我们的结果超过了3％的共同实践，甚至在某些数据集中取得了完全监督的结果。我们的源代码和预培训模型可在https://github.com/sun-asterisk-research/online学习SSL上找到

最近的成功表明，可以通过文本提示来操纵图像，例如，在雨天的晴天，在雨天中被操纵到同一场景中，这是由文本输入“下雨”驱动的雨天。这些方法经常利用基于样式的图像生成器，该生成器利用多模式（文本和图像）嵌入空间。但是，我们观察到，这种文本输入通常在提供和综合丰富的语义提示时被瓶颈瓶颈，例如将大雨与雨雨区分开。为了解决这个问题，我们主张利用另一种方式，声音，在图像操纵中具有显着优势，因为它可以传达出比文本更多样化的语义提示（生动的情感或自然世界的动态表达）。在本文中，我们提出了一种新颖的方法，该方法首先使用声音扩展了图像文本接头嵌入空间，并应用了一种直接的潜在优化方法来根据音频输入（例如雨的声音）操纵给定的图像。我们的广泛实验表明，我们的声音引导的图像操纵方法在语义和视觉上比最先进的文本和声音引导的图像操纵方法产生更合理的操作结果，这通过我们的人类评估进一步证实。我们的下游任务评估还表明，我们学到的图像文本单嵌入空间有效地编码声音输入。

野火预测一直是人文学科蓬勃发展的最关键任务之一。它在保护人类生活中起着至关重要的作用。另一方面，由于其随机和混乱的特性，野火预测很困难。我们通过将一系列野火图像解释为视频来解决问题，并用它来预测火灾将来的表现。但是，创建说明未来固有不确定性的视频预测模型是具有挑战性的。已发布的大部分尝试都是基于随机图像 - 自动回调的复发网络，该网络增加了各种性能和应用困难，例如计算成本和大量数据集的效率有限。另一种可能性是使用结合框架合成和时间动力学的完全潜在的时间模型。但是，由于设计和培训问题，文献中尚未提出过随机视频预测的这种模型。本文通过引入一种新型的随机时间模型来解决这些问题，该模型的动力学在潜在空间中驱动。它自然可以通过允许我们更轻巧，更容易解释的潜在模型来击败GOY-16数据集上的先前最新方法来预测视频动态。结果将与各种基准模型进行比较。
