艺术是一种使用数字技术作为生成或创造过程的一部分的艺术方法。随着数字货币和NFT（不可杀死的代币）的出现，对数字艺术的需求正在积极增长。在本手稿中，我们主张将深层生成网络和对抗性训练进行稳定和变体的艺术生成的概念。这项工作主要集中于使用深卷积生成对抗网络（DC-GAN），并探讨了解决GAN训练中常见陷阱的技术。我们比较DC-GAN的各种架构和设计，以为稳定而逼真的一代提供推荐的设计选择。这项工作的主要重点是生成现实中不存在但由提议的模型从随机噪声中合成的逼真图像。我们提供了生成的动物面部图像（一些显示物种混合物的证据）的视觉结果以及训练，建筑和设计选择的建议。我们还展示了训练图像预处理如何在GAN培训中起着重要作用。

This paper details our participation in the Challenges and Applications of Automated Extraction of Socio-political Events from Text (CASE) workshop @ EMNLP 2022, where we take part in Subtask 1 of Shared Task 3. We approach the given task of event causality detection by proposing a self-training pipeline that follows a teacher-student classifier method. More specifically, we initially train a teacher model on the true, original task data, and use that teacher model to self-label data to be used in the training of a separate student model for the final task prediction. We test how restricting the number of positive or negative self-labeled examples in the self-training process affects classification performance. Our final results show that using self-training produces a comprehensive performance improvement across all models and self-labeled training sets tested within the task of event causality sequence classification. On top of that, we find that self-training performance did not diminish even when restricting either positive/negative examples used in training. Our code is be publicly available at https://github.com/Gzhang-umich/1CademyTeamOfCASE.

在过去的几年中，基于深度卷积神经网络（CNN）的图像识别已取得了重大进展。这主要是由于此类网络在挖掘判别对象姿势以及质地和形状的零件信息方面具有强大的能力。这通常不适合细粒度的视觉分类（FGVC），因为它由于阻塞，变形，照明等而表现出较高的类内和较低的阶层差异。表征对象/场景。为此，我们提出了一种方法，该方法可以通过汇总大多数相关图像区域的上下文感知特征及其在区分细颗粒类别中避免边界框和/或可区分的零件注释中的重要性来有效捕获细微的变化。我们的方法的灵感来自最新的自我注意力和图形神经网络（GNNS）方法的启发端到端的学习过程。我们的模型在八个基准数据集上进行了评估，该数据集由细粒对象和人类对象相互作用组成。它的表现优于最先进的方法，其识别准确性很大。

视觉接地是一项旨在根据自然语言表达方式定位目标对象的任务。作为一项多模式任务，文本和视觉输入之间的特征相互作用至关重要。但是，先前的解决方案主要在将它们融合在一起之前独立处理每种模式，在提取视觉功能时，这并不能充分利用相关的文本信息。为了更好地利用视觉接地中的文本视觉关系，我们提出了一个查询条件的卷积模块（QCM），该模块（QCM）通过将查询信息纳入卷积内核的产生中来提取查询感知的视觉特征。借助我们提出的QCM，下游融合模块接收到更具歧视性的视觉特征，并专注于表达式中描述的所需对象，从而导致更准确的预测。在三个流行的视觉接地数据集上进行的广泛实验表明，我们的方法可以达到最新的性能。此外，当直接用于预测而无需进一步的多模式融合时，查询感知的视觉特征足以实现与最新方法可比的性能。

在计算机视觉中，对现实世界图像的自我监督，类别不足的分割是一个具有挑战性的开放问题。在这里，我们通过基于Spelke对象的认知科学概念来展示如何从运动自学学习中学习静态分组先验：一组可以一起移动的物理内容。我们介绍了兴奋性抑制段提取网络（EISEN），该网络学会从基于运动的训练信号中提取成对的亲和力图，以供静态场景。然后，艾森使用新颖的图形传播和竞争网络从亲和力产生细分市场。在训练过程中，进行相关运动的对象（例如机器人臂和移动的对象）被引导过程解耦：Eisen解释了它已经学会了细分的对象的运动。我们表明，艾森（Eisen）在挑战合成和现实世界的机器人数据集上进行了自我监督的图像分割方面取得了重大改进。

尽管当前的视觉算法在许多具有挑战性的任务上都表现出色，但尚不清楚他们如何理解现实世界环境的物理动态。在这里，我们介绍了Physion，一种数据集和基准，用于严格评估预测物理场景如何随着时间而发展的能力。我们的数据集具有对各种物理现象的现实模拟，包括刚性和软体体碰撞，稳定的多对象配置，滚动，滑动和弹丸运动，因此比以前的基准提供了更全面的挑战。我们使用Physion来基准一套模型，其体系结构，学习目标，投入输出结构和培训数据各不相同。同时，我们在同一场景上获得了人类预测行为的精确测量，从而使我们能够直接评估任何模型能够近似人类行为的效果。我们发现，学习以对象为中心的表示的视觉算法通常优于那些没有人的表现，但仍未达到人类绩效。另一方面，绘制具有直接访问物理状态信息的神经网络的表现效果更好，并且做出与人类制作的预测更相似。这些结果表明，提取场景的物理表征是在视力算法中实现人类水平和类似人类的物理理解的主要瓶颈。我们已公开发布了所有数据和代码，以促进使用物理以完全可重现的方式对其他模型进行基准测试，从而使对视觉算法的进度进行系统的评估，这些算法像人们一样坚固地了解物理环境。

我们介绍了ThreedWorld（TDW），是交互式多模态物理模拟的平台。 TDW能够模拟高保真感官数据和富裕的3D环境中的移动代理和对象之间的物理交互。独特的属性包括：实时近光 - 真实图像渲染;对象和环境库，以及他们定制的例程;有效构建新环境课程的生成程序;高保真音频渲染;各种材料类型的现实物理相互作用，包括布料，液体和可变形物体;可定制的代理体现AI代理商;并支持与VR设备的人类交互。 TDW的API使多个代理能够在模拟中进行交互，并返回一系列表示世界状态的传感器和物理数据。我们在计算机视觉，机器学习和认知科学中的新兴的研究方向上提供了通过TDW的初始实验，包括多模态物理场景理解，物理动态预测，多代理交互，像孩子一样学习的模型，并注意研究人类和神经网络。

We present a dynamic path planning algorithm to navigate an amphibious rotor craft through a concave time-invariant obstacle field while attempting to minimize energy usage. We create a nonlinear quaternion state model that represents the rotor craft dynamics above and below the water. The 6 degree of freedom dynamics used within a layered architecture to generate motion paths for the vehicle to follow and the required control inputs. The rotor craft has a 3 dimensional map of its surroundings that is updated via limited range onboard sensor readings within the current medium (air or water). Path planning is done via PRM and D* Lite.

When robots learn reward functions using high capacity models that take raw state directly as input, they need to both learn a representation for what matters in the task -- the task ``features" -- as well as how to combine these features into a single objective. If they try to do both at once from input designed to teach the full reward function, it is easy to end up with a representation that contains spurious correlations in the data, which fails to generalize to new settings. Instead, our ultimate goal is to enable robots to identify and isolate the causal features that people actually care about and use when they represent states and behavior. Our idea is that we can tune into this representation by asking users what behaviors they consider similar: behaviors will be similar if the features that matter are similar, even if low-level behavior is different; conversely, behaviors will be different if even one of the features that matter differs. This, in turn, is what enables the robot to disambiguate between what needs to go into the representation versus what is spurious, as well as what aspects of behavior can be compressed together versus not. The notion of learning representations based on similarity has a nice parallel in contrastive learning, a self-supervised representation learning technique that maps visually similar data points to similar embeddings, where similarity is defined by a designer through data augmentation heuristics. By contrast, in order to learn the representations that people use, so we can learn their preferences and objectives, we use their definition of similarity. In simulation as well as in a user study, we show that learning through such similarity queries leads to representations that, while far from perfect, are indeed more generalizable than self-supervised and task-input alternatives.

Machine learning methods have seen increased application to geospatial environmental problems, such as precipitation nowcasting, haze forecasting, and crop yield prediction. However, many of the machine learning methods applied to mosquito population and disease forecasting do not inherently take into account the underlying spatial structure of the given data. In our work, we apply a spatially aware graph neural network model consisting of GraphSAGE layers to forecast the presence of West Nile virus in Illinois, to aid mosquito surveillance and abatement efforts within the state. More generally, we show that graph neural networks applied to irregularly sampled geospatial data can exceed the performance of a range of baseline methods including logistic regression, XGBoost, and fully-connected neural networks.
