训练后量化（PTQ）由于其在部署量化的神经网络方面的便利性而引起了越来越多的关注。 Founding是量化误差的主要来源，仅针对模型权重进行了优化，而激活仍然使用圆形至最终操作。在这项工作中，我们首次证明了精心选择的激活圆形方案可以提高最终准确性。为了应对激活舍入方案动态性的挑战，我们通过简单的功能适应圆形边框，以在推理阶段生成圆形方案。边界函数涵盖了重量误差，激活错误和传播误差的影响，以消除元素误差的偏差，从而进一步受益于模型的准确性。我们还使边境意识到全局错误，以更好地拟合不同的到达激活。最后，我们建议使用Aquant框架来学习边界功能。广泛的实验表明，与最先进的作品相比，Aquant可以通过可忽略不计的开销来取得明显的改进，并将Resnet-18的精度提高到2位重量和激活后训练后量化下的精度最高60.3 \％。

在这项工作中，我们介绍了梯度暹罗网络（GSN）进行图像质量评估。所提出的方法熟练地捕获了全参考图像质量评估（IQA）任务中扭曲的图像和参考图像之间的梯度特征。我们利用中央微分卷积获得图像对中隐藏的语义特征和细节差异。此外，空间注意力指导网络专注于与图像细节相关的区域。对于网络提取的低级，中级和高级功能，我们创新设计了一种多级融合方法，以提高功能利用率的效率。除了常见的均方根错误监督外，我们还进一步考虑了批处理样本之间的相对距离，并成功地将KL差异丢失应用于图像质量评估任务。我们在几个公开可用的数据集上试验了提出的算法GSN，并证明了其出色的性能。我们的网络赢得了NTIRE 2022感知图像质量评估挑战赛1的第二名。

面部反欺骗研究被广泛用于面部识别，并受到行业和学者的更多关注。在本文中，我们提出了Eulernet，这是一个新的时间特征融合网络，其中差分过滤器和残留金字塔分别用于从连续帧中提取和扩增异常线索。基于面部标志的轻量级样品标签方法旨在以较低的成本标记大型样品，并且比其他方法（例如3D摄像头）具有更好的结果。最后，我们使用各种移动端来收集30,000个实时和欺骗样本，以创建一个数据集，该数据集在现实世界中复制各种形式的攻击。公共Oulu-NPU的广泛实验表明，我们的算法优于最先进的现状，我们的解决方案已经部署在现实世界中，为数百万用户提供服务。

Covid-19的传播给世界带来了巨大的灾难，自动分割感染区域可以帮助医生快速诊断并减少工作量。但是，准确和完整的分割面临一些挑战，例如散射的感染区分布，复杂的背景噪声和模糊的分割边界。为此，在本文中，我们提出了一个新的网络，用于从CT图像（名为BCS-NET）的自动covid-19肺部感染分割，该网络考虑了边界，上下文和语义属性。 BCS-NET遵循编码器架构，更多的设计集中在解码器阶段，该阶段包括三个逐渐边界上下文 - 语义重建（BCSR）块。在每个BCSR块中，注意引导的全局上下文（AGGC）模块旨在通过突出显示重要的空间和边界位置并建模全局上下文依赖性来学习解码器最有价值的编码器功能。此外，语义指南（SG）单元通过在中间分辨率上汇总多规模的高级特征来生成语义指南图来完善解码器特征。广泛的实验表明，我们提出的框架在定性和定量上都优于现有竞争对手。

现在，人工智能（AI）可以自动解释医学图像以供临床使用。但是，AI在介入图像中的潜在用途（相对于参与分类或诊断的图像），例如在手术期间的指导，在很大程度上尚未开发。这是因为目前，使用现场分析对现场手术收集的数据进行了事后分析，这是因为手术AI系统具有基本和实际限制，包括道德考虑，费用，可扩展性，数据完整性以及缺乏地面真相。在这里，我们证明从人类模型中创建逼真的模拟图像是可行的替代方法，并与大规模的原位数据收集进行了补充。我们表明，对现实合成数据的训练AI图像分析模型，结合当代域的概括或适应技术，导致在实际数据上的模型与在精确匹配的真实数据训练集中训练的模型相当地执行的模型。由于从基于人类的模型尺度的合成生成培训数据，因此我们发现我们称为X射线图像分析的模型传输范式（我们称为Syntheex）甚至可以超越实际数据训练的模型，因为训练的有效性较大的数据集。我们证明了合成在三个临床任务上的潜力：髋关节图像分析，手术机器人工具检测和COVID-19肺病变分割。 Synthex提供了一个机会，可以极大地加速基于X射线药物的智能系统的概念，设计和评估。此外，模拟图像环境还提供了测试新颖仪器，设计互补手术方法的机会，并设想了改善结果，节省时间或减轻人为错误的新技术，从实时人类数据收集的道德和实际考虑方面摆脱了人为错误。

基于能量的模型（EBMS）为密度估计提供了优雅的框架，但它们难以训练。最近的工作已经建立了与生成的对抗网络的联系，eBM通过具有变分值函数的最小游戏培训。我们提出了EBM Log-似然的双向界限，使得我们最大限度地提高了较低的界限，并在解决Minimax游戏时最小化上限。我们将一个绑定到梯度惩罚的一个稳定，稳定培训，从而提供最佳工程实践的基础。为了评估界限，我们开发了EBM发生器的Jacobi确定的新的高效估算器。我们证明这些发展显着稳定培训并产生高质量密度估计和样品生成。

In this paper, we study the problem of knowledge-intensive text-to-SQL, in which domain knowledge is necessary to parse expert questions into SQL queries over domain-specific tables. We formalize this scenario by building a new Chinese benchmark KnowSQL consisting of domain-specific questions covering various domains. We then address this problem by presenting formulaic knowledge, rather than by annotating additional data examples. More concretely, we construct a formulaic knowledge bank as a domain knowledge base and propose a framework (ReGrouP) to leverage this formulaic knowledge during parsing. Experiments using ReGrouP demonstrate a significant 28.2% improvement overall on KnowSQL.

Weakly-supervised object localization aims to indicate the category as well as the scope of an object in an image given only the image-level labels. Most of the existing works are based on Class Activation Mapping (CAM) and endeavor to enlarge the discriminative area inside the activation map to perceive the whole object, yet ignore the co-occurrence confounder of the object and context (e.g., fish and water), which makes the model inspection hard to distinguish object boundaries. Besides, the use of CAM also brings a dilemma problem that the classification and localization always suffer from a performance gap and can not reach their highest accuracy simultaneously. In this paper, we propose a casual knowledge distillation method, dubbed KD-CI-CAM, to address these two under-explored issues in one go. More specifically, we tackle the co-occurrence context confounder problem via causal intervention (CI), which explores the causalities among image features, contexts, and categories to eliminate the biased object-context entanglement in the class activation maps. Based on the de-biased object feature, we additionally propose a multi-teacher causal distillation framework to balance the absorption of classification knowledge and localization knowledge during model training. Extensive experiments on several benchmarks demonstrate the effectiveness of KD-CI-CAM in learning clear object boundaries from confounding contexts and addressing the dilemma problem between classification and localization performance.

Dynamic treatment regimes assign personalized treatments to patients sequentially over time based on their baseline information and time-varying covariates. In mobile health applications, these covariates are typically collected at different frequencies over a long time horizon. In this paper, we propose a deep spectral Q-learning algorithm, which integrates principal component analysis (PCA) with deep Q-learning to handle the mixed frequency data. In theory, we prove that the mean return under the estimated optimal policy converges to that under the optimal one and establish its rate of convergence. The usefulness of our proposal is further illustrated via simulations and an application to a diabetes dataset.

Nowadays, time-stamped web documents related to a general news query floods spread throughout the Internet, and timeline summarization targets concisely summarizing the evolution trajectory of events along the timeline. Unlike traditional document summarization, timeline summarization needs to model the time series information of the input events and summarize important events in chronological order. To tackle this challenge, in this paper, we propose a Unified Timeline Summarizer (UTS) that can generate abstractive and extractive timeline summaries in time order. Concretely, in the encoder part, we propose a graph-based event encoder that relates multiple events according to their content dependency and learns a global representation of each event. In the decoder part, to ensure the chronological order of the abstractive summary, we propose to extract the feature of event-level attention in its generation process with sequential information remained and use it to simulate the evolutionary attention of the ground truth summary. The event-level attention can also be used to assist in extracting summary, where the extracted summary also comes in time sequence. We augment the previous Chinese large-scale timeline summarization dataset and collect a new English timeline dataset. Extensive experiments conducted on these datasets and on the out-of-domain Timeline 17 dataset show that UTS achieves state-of-the-art performance in terms of both automatic and human evaluations.
