反向工程从其他表示形式进行的CAD形状是许多下游应用程序的重要几何处理步骤。在这项工作中，我们介绍了一种新型的神经网络体系结构，以解决这项具有挑战性的任务，并使用可编辑，受约束的棱镜CAD模型近似平滑的签名距离函数。在训练过程中，我们的方法通过将形状分解为一系列2D轮廓图像和1D包膜函数来重建体素空间中的输入几何形状。然后可以以不同的方式重新组合这些，以允许定义几何损失函数。在推断期间，我们通过首先搜索2D约束草图的数据库来获取CAD数据，以找到近似配置文件图像的曲线，然后将它们挤出并使用布尔操作来构建最终的CAD模型。我们的方法比其他方法更接近目标形状，并输出与现有CAD软件兼容的高度可编辑的约束参数草图。

我们提出了Kkexgen，这是一种用于计算机辅助设计（CAD）构造序列的新型自回旋生成模型，其中包含草图和伸出的建模操作。我们的模型利用不同的变压器体系结构编码构造序列的拓扑，几何和挤压变化为分离的代码簿。自回归变压器解码器生成CAD构造序列，共享代码簿向量指定的某些属性。广泛的实验表明，我们的删除代码书表示会生成多样化和高质量的CAD模型，增强用户控制，并有效地探索设计空间。该代码可在https://samxuxiang.github.io/skexgen上找到。

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。

物理产品通常是复杂的组件，组合计算机辅助设计（CAD）软件中建模的多个3D零件。CAD Designers通过使用称为关节的约束对齐各个部件来构建这些程序集。在本文中，我们介绍了可连接，一种基于学习的方法，可以将部件组合在一起以形成关节。可加入使用标准参数CAD文件中提供的弱监管，而无需对象类标签或人类指导。我们的研究结果表明，通过对实体模型的图表表示进行网络预测，我们可以优于多种基线方法，精度（79.53％）接近人类性能（80％）。最后，为了支持未来的研究，我们释放了Fusion 360 Gallery集合数据集，其中包含了具有关于关节，接触表面，孔和底层装配图结构的丰富信息的程序集。

The recent increase in public and academic interest in preserving biodiversity has led to the growth of the field of conservation technology. This field involves designing and constructing tools that utilize technology to aid in the conservation of wildlife. In this article, we will use case studies to demonstrate the importance of designing conservation tools with human-wildlife interaction in mind and provide a framework for creating successful tools. These case studies include a range of complexities, from simple cat collars to machine learning and game theory methodologies. Our goal is to introduce and inform current and future researchers in the field of conservation technology and provide references for educating the next generation of conservation technologists. Conservation technology not only has the potential to benefit biodiversity but also has broader impacts on fields such as sustainability and environmental protection. By using innovative technologies to address conservation challenges, we can find more effective and efficient solutions to protect and preserve our planet's resources.

As various city agencies and mobility operators navigate toward innovative mobility solutions, there is a need for strategic flexibility in well-timed investment decisions in the design and timing of mobility service regions, i.e. cast as "real options" (RO). This problem becomes increasingly challenging with multiple interacting RO in such investments. We propose a scalable machine learning based RO framework for multi-period sequential service region design & timing problem for mobility-on-demand services, framed as a Markov decision process with non-stationary stochastic variables. A value function approximation policy from literature uses multi-option least squares Monte Carlo simulation to get a policy value for a set of interdependent investment decisions as deferral options (CR policy). The goal is to determine the optimal selection and timing of a set of zones to include in a service region. However, prior work required explicit enumeration of all possible sequences of investments. To address the combinatorial complexity of such enumeration, we propose a new variant "deep" RO policy using an efficient recurrent neural network (RNN) based ML method (CR-RNN policy) to sample sequences to forego the need for enumeration, making network design & timing policy tractable for large scale implementation. Experiments on multiple service region scenarios in New York City (NYC) shows the proposed policy substantially reduces the overall computational cost (time reduction for RO evaluation of > 90% of total investment sequences is achieved), with zero to near-zero gap compared to the benchmark. A case study of sequential service region design for expansion of MoD services in Brooklyn, NYC show that using the CR-RNN policy to determine optimal RO investment strategy yields a similar performance (0.5% within CR policy value) with significantly reduced computation time (about 5.4 times faster).

The combination of conduct, emotion, motivation, and thinking is referred to as personality. To shortlist candidates more effectively, many organizations rely on personality predictions. The firm can hire or pick the best candidate for the desired job description by grouping applicants based on the necessary personality preferences. A model is created to identify applicants' personality types so that employers may find qualified candidates by examining a person's facial expression, speech intonation, and resume. Additionally, the paper emphasises detecting the changes in employee behaviour. Employee attitudes and behaviour towards each set of questions are being examined and analysed. Here, the K-Modes clustering method is used to predict employee well-being, including job pressure, the working environment, and relationships with peers, utilizing the OCEAN Model and the CNN algorithm in the AVI-AI administrative system. Findings imply that AVIs can be used for efficient candidate screening with an AI decision agent. The study of the specific field is beyond the current explorations and needed to be expanded with deeper models and new configurations that can patch extremely complex operations.

Correct scoring of a driver's risk is of great significance to auto insurance companies. While the current tools used in this field have been proven in practice to be quite efficient and beneficial, we argue that there is still a lot of room for development and improvement in the auto insurance risk estimation process. To this end, we develop a framework based on a combination of a neural network together with a dimensionality reduction technique t-SNE (t-distributed stochastic neighbour embedding). This enables us to visually represent the complex structure of the risk as a two-dimensional surface, while still preserving the properties of the local region in the features space. The obtained results, which are based on real insurance data, reveal a clear contrast between the high and low risk policy holders, and indeed improve upon the actual risk estimation performed by the insurer. Due to the visual accessibility of the portfolio in this approach, we argue that this framework could be advantageous to the auto insurer, both as a main risk prediction tool and as an additional validation stage in other approaches.

As language models (LMs) scale, they develop many novel behaviors, good and bad, exacerbating the need to evaluate how they behave. Prior work creates evaluations with crowdwork (which is time-consuming and expensive) or existing data sources (which are not always available). Here, we automatically generate evaluations with LMs. We explore approaches with varying amounts of human effort, from instructing LMs to write yes/no questions to making complex Winogender schemas with multiple stages of LM-based generation and filtering. Crowdworkers rate the examples as highly relevant and agree with 90-100% of labels, sometimes more so than corresponding human-written datasets. We generate 154 datasets and discover new cases of inverse scaling where LMs get worse with size. Larger LMs repeat back a dialog user's preferred answer ("sycophancy") and express greater desire to pursue concerning goals like resource acquisition and goal preservation. We also find some of the first examples of inverse scaling in RL from Human Feedback (RLHF), where more RLHF makes LMs worse. For example, RLHF makes LMs express stronger political views (on gun rights and immigration) and a greater desire to avoid shut down. Overall, LM-written evaluations are high-quality and let us quickly discover many novel LM behaviors.

We present Azimuth, an open-source and easy-to-use tool to perform error analysis for text classification. Compared to other stages of the ML development cycle, such as model training and hyper-parameter tuning, the process and tooling for the error analysis stage are less mature. However, this stage is critical for the development of reliable and trustworthy AI systems. To make error analysis more systematic, we propose an approach comprising dataset analysis and model quality assessment, which Azimuth facilitates. We aim to help AI practitioners discover and address areas where the model does not generalize by leveraging and integrating a range of ML techniques, such as saliency maps, similarity, uncertainty, and behavioral analyses, all in one tool. Our code and documentation are available at github.com/servicenow/azimuth.
