To effectively train accurate Relation Extraction models, sufficient and properly labeled data is required. Adequately labeled data is difficult to obtain and annotating such data is a tricky undertaking. Previous works have shown that either accuracy has to be sacrificed or the task is extremely time-consuming, if done accurately. We are proposing an approach in order to produce high-quality datasets for the task of Relation Extraction quickly. Neural models, trained to do Relation Extraction on the created datasets, achieve very good results and generalize well to other datasets. In our study, we were able to annotate 10,022 sentences for 19 relations in a reasonable amount of time, and trained a commonly used baseline model for each relation.

With an increasing amount of data in the art world, discovering artists and artworks suitable to collectors' tastes becomes a challenge. It is no longer enough to use visual information, as contextual information about the artist has become just as important in contemporary art. In this work, we present a generic Natural Language Processing framework (called ArtLM) to discover the connections among contemporary artists based on their biographies. In this approach, we first continue to pre-train the existing general English language models with a large amount of unlabelled art-related data. We then fine-tune this new pre-trained model with our biography pair dataset manually annotated by a team of professionals in the art industry. With extensive experiments, we demonstrate that our ArtLM achieves 85.6% accuracy and 84.0% F1 score and outperforms other baseline models. We also provide a visualisation and a qualitative analysis of the artist network built from ArtLM's outputs.

Applications such as employees sharing office spaces over a workweek can be modeled as problems where agents are matched to resources over multiple rounds. Agents' requirements limit the set of compatible resources and the rounds in which they want to be matched. Viewing such an application as a multi-round matching problem on a bipartite compatibility graph between agents and resources, we show that a solution (i.e., a set of matchings, with one matching per round) can be found efficiently if one exists. To cope with situations where a solution does not exist, we consider two extensions. In the first extension, a benefit function is defined for each agent and the objective is to find a multi-round matching to maximize the total benefit. For a general class of benefit functions satisfying certain properties (including diminishing returns), we show that this multi-round matching problem is efficiently solvable. This class includes utilitarian and Rawlsian welfare functions. For another benefit function, we show that the maximization problem is NP-hard. In the second extension, the objective is to generate advice to each agent (i.e., a subset of requirements to be relaxed) subject to a budget constraint so that the agent can be matched. We show that this budget-constrained advice generation problem is NP-hard. For this problem, we develop an integer linear programming formulation as well as a heuristic based on local search. We experimentally evaluate our algorithms on synthetic networks and apply them to two real-world situations: shared office spaces and matching courses to classrooms.

It is well known that the performance of any classification model is effective if the dataset used for the training process and the test process satisfy some specific requirements. In other words, the more the dataset size is large, balanced, and representative, the more one can trust the proposed model's effectiveness and, consequently, the obtained results. Unfortunately, large-size anonymous datasets are generally not publicly available in biomedical applications, especially those dealing with pathological human face images. This concern makes using deep-learning-based approaches challenging to deploy and difficult to reproduce or verify some published results. In this paper, we suggest an efficient method to generate a realistic anonymous synthetic dataset of human faces with the attributes of acne disorders corresponding to three levels of severity (i.e. Mild, Moderate and Severe). Therefore, a specific hierarchy StyleGAN-based algorithm trained at distinct levels is considered. To evaluate the performance of the proposed scheme, we consider a CNN-based classification system, trained using the generated synthetic acneic face images and tested using authentic face images. Consequently, we show that an accuracy of 97,6\% is achieved using InceptionResNetv2. As a result, this work allows the scientific community to employ the generated synthetic dataset for any data processing application without restrictions on legal or ethical concerns. Moreover, this approach can also be extended to other applications requiring the generation of synthetic medical images. We can make the code and the generated dataset accessible for the scientific community.

该报告解释，实施和扩展了“更紧密的变化界限不一定更好”所介绍的作品（T Rainforth等，2018）。我们提供了理论和经验证据，这些证据增加了重要性的重要性数量$ k $在重要性加权自动编码器（IWAE）中（Burda等，2016）降低了推理中梯度估计量的信噪比（SNR）网络，从而影响完整的学习过程。换句话说，即使增加$ k $减少了梯度的标准偏差，但它也会更快地降低真实梯度的幅度，从而增加梯度更新的相对差异。进行广泛的实验以了解$ k $的重要性。这些实验表明，更紧密的变化界限对生成网络有益，而宽松的边界对推理网络来说是可取的。通过这些见解，可以实施和研究三种方法：部分重要性加权自动编码器（PIWAE），倍增重要性加权自动编码器（MIWAE）和组合重要性加权自动编码器（CIWAE）。这三种方法中的每一种都需要IWAE作为一种特殊情况，但采用不同的重量权重，以确保较高的梯度估计器的SNR。在我们的研究和分析中，这些算法的疗效在多个数据集（如MNIST和Omniglot）上进行了测试。最后，我们证明了三种呈现的IWAE变化能够产生近似后验分布，这些分布与IWAE更接近真正的后验分布，同时匹配IWAE生成网络的性能，或者在PIWAE的情况下可能超过其表现。

文化遗产的理解和保存对于社会来说是一个重要的问题，因为它代表了其身份的基本方面。绘画代表了文化遗产的重要组成部分，并且是不断研究的主题。但是，观众认为绘画与所谓的HVS（人类视觉系统）行为严格相关。本文重点介绍了一定数量绘画的视觉体验期间观众的眼动分析。在进一步的详细信息中，我们引入了一种新的方法来预测人类的视觉关注，这影响了人类的几种认知功能，包括对场景的基本理解，然后将其扩展到绘画图像。拟议的新建筑摄入图像并返回扫描路径，这是一系列积分，具有引起观众注意力的很有可能性。我们使用FCNN（完全卷积的神经网络），其中利用了可区分的渠道选择和软弧度模块。我们还将可学习的高斯分布纳入网络瓶颈上，以模拟自然场景图像中的视觉注意力过程偏见。此外，为了减少不同域之间的变化影响（即自然图像，绘画），我们敦促模型使用梯度反转分类器从其他域中学习无监督的一般特征。在准确性和效率方面，我们的模型获得的结果优于现有的最先进的结果。

在基于学术和行业的研究中，在线评估方法都被视为推荐系统等交互式应用程序的黄金标准。自然，这样做的原因是，我们可以直接测量依赖干预措施的实用程序指标，这是向用户显示的建议。然而，由于多种原因，在线评估方法是昂贵的，并且对于可靠的离线评估程序仍然存在明确的需求。在行业中，离线指标通常被用作一线评估，以生成有前途的候选模型来在线评估。在学术工作中，对在线系统的有限访问使离线指标是验证新方法的事实上的方法。存在两个类别的离线指标：基于代理的方法和反事实方法。头等舱通常与我们关心的在线指标相关，而后一类仅根据在现实世界中无法实现的假设提供理论保证。在这里，我们表明基于模拟的比较为离线指标提供了前进的方向，并认为它们是可取的评估手段。

我们设计和分析了量子变压器，扩展了最先进的经典变压器神经网络体系结构，已知在自然语言处理和图像分析中表现出色。在先前用于数据加载和正交神经层的参数化量子电路的工作的基础上，我们引入了三种量子注意机制，包括基于复合矩阵的量子变压器。这些量子体系结构可以使用浅量子电路构建，并可以提供定性不同的分类模型。与最佳的经典变压器和其他经典基准相比，我们对标准医疗图像数据集进行了量子变压器的广泛模拟，这些量子变压器表现出竞争力，有时表现更好。与经典算法相对于分类图像的大小，我们的量子注意层的计算复杂性被证明是有利的。与拥有数百万参数的最佳经典方法相比，我们的量子体系结构具有数千个参数。最后，我们在超导量子计算机上实施了量子变压器，并获得了多达六个量子实验的令人鼓舞的结果。

大多数经典的大满贯系统都依赖于静态场景假设，这限制了其在现实世界中的适用性。最近提出了最近的SLAM框架来同时跟踪相机和移动对象。但是，他们通常无法估计物体的规范姿势并表现出低对象跟踪精度。为了解决这个问题，我们提出了Twistslam ++，这是一种语义，动态的，全动态的，可融合立体声图像和LiDAR信息。使用语义信息，我们跟踪可能移动对象，并将它们与LIDAR扫描中的3D对象检测相关联，以获得其姿势和尺寸。然后，我们对连续对象扫描进行注册以完善对象姿势估计。最后，使用对象扫描来估计对象的形状，并约束MAP点位于BA内的估计表面上。我们在经典的基准上表明，基于多模式信息的这种融合方法提高了对象跟踪的准确性。

许多情况下，具有限制代理商竞争资源的代理商可以作为两分图上的最大匹配问题施放。我们的重点是资源分配问题，在这些问题上，代理可能会限制与某些资源不兼容的限制。我们假设一个原理可以随机选择最大匹配，以便每个代理都具有一定概率的资源。代理商希望通过在一定范围内修改限制来提高他们的匹配机会。原则的目标是建议一个不满意的代理商放松其限制，以便放松的总成本在预算范围内（代理商选择），并最大程度地提高了分配资源的可能性。我们为这种预算受限的最大化问题的某些变体建立硬度结果，并为其他变体提供算法结果。我们通过实验评估合成数据集以及两个新颖的现实数据集：度假活动数据集和一个教室数据集的方法。
