我们提出了一个Point2cyl，一个监督网络将原始3D点云变换到一组挤出缸。从原始几何到CAD模型的逆向工程是能够在形状编辑软件中操纵3D数据的重要任务，从而在许多下游应用中扩展其使用。特别地，具有挤出圆柱序列的CAD模型的形式 - 2D草图加上挤出轴和范围 - 以及它们的布尔组合不仅广泛应用于CAD社区/软件，而且相比具有很大的形状表现性具有有限类型的基元（例如，平面，球形和汽缸）。在这项工作中，我们介绍了一种神经网络，通过首先学习底层几何代理来解决挤出汽缸分解问题的挤出圆柱分解问题。精确地，我们的方法首先预测每点分割，基础/桶标签和法线，然后估计可分离和闭合形式配方中的底层挤出参数。我们的实验表明，我们的方法展示了两个最近CAD数据集，融合画廊和Deepcad上的最佳性能，我们进一步展示了逆向工程和编辑的方法。

Deep learning techniques for point cloud data have demonstrated great potentials in solving classical problems in 3D computer vision such as 3D object classification and segmentation. Several recent 3D object classification methods have reported state-of-the-art performance on CAD model datasets such as ModelNet40 with high accuracy (∼92%). Despite such impressive results, in this paper, we argue that object classification is still a challenging task when objects are framed with real-world settings. To prove this, we introduce ScanObjectNN, a new real-world point cloud object dataset based on scanned indoor scene data. From our comprehensive benchmark, we show that our dataset poses great challenges to existing point cloud classification techniques as objects from real-world scans are often cluttered with background and/or are partial due to occlusions. We identify three key open problems for point cloud object classification, and propose new point cloud classification neural networks that achieve state-of-the-art performance on classifying objects with cluttered background. Our dataset and code are publicly available in our project page 1 .

We identify the task of measuring data to quantitatively characterize the composition of machine learning data and datasets. Similar to an object's height, width, and volume, data measurements quantify different attributes of data along common dimensions that support comparison. Several lines of research have proposed what we refer to as measurements, with differing terminology; we bring some of this work together, particularly in fields of computer vision and language, and build from it to motivate measuring data as a critical component of responsible AI development. Measuring data aids in systematically building and analyzing machine learning (ML) data towards specific goals and gaining better control of what modern ML systems will learn. We conclude with a discussion of the many avenues of future work, the limitations of data measurements, and how to leverage these measurement approaches in research and practice.

Data-driven modeling has become a key building block in computational science and engineering. However, data that are available in science and engineering are typically scarce, often polluted with noise and affected by measurement errors and other perturbations, which makes learning the dynamics of systems challenging. In this work, we propose to combine data-driven modeling via operator inference with the dynamic training via roll outs of neural ordinary differential equations. Operator inference with roll outs inherits interpretability, scalability, and structure preservation of traditional operator inference while leveraging the dynamic training via roll outs over multiple time steps to increase stability and robustness for learning from low-quality and noisy data. Numerical experiments with data describing shallow water waves and surface quasi-geostrophic dynamics demonstrate that operator inference with roll outs provides predictive models from training trajectories even if data are sampled sparsely in time and polluted with noise of up to 10%.

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

尽管最近的研究集中在量化单词用法上以找到叙事情感弧的整体形状，但叙事中叙事的某些特征仍有待探索。在这里，我们通过找到单词用法中波动开始相关的文本长度来表征亚叙事的叙事时间尺度。我们代表30,000多个项目Gutenberg书籍作为时间序列使用OusiOmetrics，这是一个具有基本含义的功率破坏者框架，本身是对价价 - 宽松义务框架的重新解释，这些框架源自语义差异。我们使用经验模式分解将每本书的力量和危险时间序列分解为组成振荡模式和非振荡趋势的总和。通过将原始力量和危险时间序列的分解与从洗牌文本中得出的分解，我们发现较短的书籍仅显示出一般趋势，而较长的书籍除了一般趋势外，还具有波动，类似于子图在一个中的弧线中的弧线。总体叙事弧。这些波动通常有几千个单词的时期，无论书籍长度或库分类代码如何，但根据书的内容和结构而有所不同。我们的方法提供了一种数据驱动的denoisising方法，可用于各种长度的文本，与使用大型窗口尺寸的更传统的方法相反，该方法可能会无意中平滑相关信息，尤其是对于较短的文本而言。

对任何人类语言的文本的语法分析通常涉及许多基本的处理任务，例如令牌化，形态标记和依赖性解析。最先进的系统可以在具有大数据集的语言上实现这些任务的高精度，但是对于几乎没有带注释的数据的他的他加禄语等语言的结果很差。为了解决他加禄语语言的此问题，我们研究了在没有带注释的他加禄语数据的情况下使用辅助数据源来创建特定于任务模型的使用。我们还探索了单词嵌入和数据扩展的使用，以提高性能，而只有少量带注释的他加禄语数据可用。我们表明，与最先进的监督基线相比，这些零射击和几乎没有射击的方法在对域内和域外的塔加尔teact文本进行了语法分析方面进行了实质性改进。

通常通过过去的选择来告知机器学习中的评估，例如要使用哪些数据集或指标。该标准化可以使用排行榜对平等基础进行比较，但是随着出现更好的替代方案，评估选择变得不佳。这个问题在自然语言生成中尤其相关，该语言需要不断改善的数据集，指标和人类评估以提出确定性的主张。为了使遵循最佳模型评估实践更加容易，我们介绍了GEMV2。新版本的一代，评估和指标基准为数据集，模型和指标开发人员提供了模块化基础架构，以使彼此受益。GEMV2支持40种记录的数据集中51种语言。所有数据集的模型都可以在线评估，我们的交互式数据卡创建和渲染工具使得在Living Benchmark中添加新数据集变得更加容易。

已知性别偏见存在于大规模的视觉数据集中，并且可以在下游模型中反映甚至扩大。许多先前的作品通常通过尝试从图像中删除性别表达信息来减轻性别偏见。为了理解这些方法的可行性和实用性，我们研究了大规模视觉数据集中存在的$ \ textit {gengender伪像} $。我们将$ \ textit {性别伪像} $定义为与性别相关的视觉提示，专门针对那些由现代图像分类器学习并具有可解释的人类推论的线索。通过我们的分析，我们发现性别伪像在可可和开放型数据集中无处不在，从低级信息（例如，颜色通道的平均值）到图像的高级组成（例如姿势和姿势和姿势，，，，，，，，，地和图像的平均值），无处不在（例如，姿势和姿势，姿势和姿势，，，姿势和姿势，是姿势和姿势，是姿势和姿势，是姿势和姿势的平均值）。人的位置）。鉴于性别文物的流行，我们声称试图从此类数据集中删除性别文物的尝试是不可行的。取而代之的是，责任在于研究人员和从业人员意识到数据集中图像的分布是高度性别的，因此开发了对各组之间这些分配变化的强大方法。

以前的工作在很大程度上通过“偏见”的透镜指定的镜头考虑了图像字幕系统的公平性。相比之下，我们提供了一组技术，用于测量五种类型的代表性危害以及使用最流行的图像标题数据集获得的最终测量结果。我们的目标不是审核此图像字幕系统，而是要开发规范性的测量技术，进而提供了一个机会来反思所涉及的许多挑战。我们提出了每种危害类型的多种测量技术。我们认为，这样做可以更好地捕获每种危害的多方面性质，从而改善了所得测量值的（集体）有效性。在整个过程中，我们讨论了我们的测量方法的基础假设，并指出了它们不进行的假设。
