在这项研究中，我们提出了一种基于词素的方案，用于韩国依赖解析，并采用拟议方案来普遍依赖。我们介绍了语言原理，该基本原理说明了采用基于词素的格式的动机和必要性，并开发了脚本，这些脚本会在通用依赖项使用的原始格式和所提出的基于词素的格式自动之间转换。然后，统计和神经模型（包括udpipe和stanza）证明了提出的格式对韩国依赖解析的有效性，并以我们精心构造的基于词素的单词嵌入韩语。Morphud的表现优于所有韩国UD Treebanks的解析结果，我们还提供了详细的错误分析。

通用形态（UNIMORPH）项目是一项合作的努力，可为数百种世界语言实例化覆盖范围的标准化形态拐角。该项目包括两个主要的推力：一种无独立的特征架构，用于丰富的形态注释，并以各种语言意识到该模式的各种语言的带注释数据的类型级别资源。本文介绍了过去几年对几个方面的扩张和改进（自McCarthy等人（2020年）以来）。众多语言学家的合作努力增加了67种新语言，其中包括30种濒危语言。我们已经对提取管道进行了一些改进，以解决一些问题，例如缺少性别和马克龙信息。我们还修改了模式，使用了形态学现象所需的层次结构，例如多肢体协议和案例堆叠，同时添加了一些缺失的形态特征，以使模式更具包容性。鉴于上一个UniMorph版本，我们还通过16种语言的词素分割增强了数据库。最后，这个新版本通过通过代表来自metphynet的派生过程的实例丰富数据和注释模式来推动将衍生物形态纳入UniMorph中。

The Common Voice corpus is a massively-multilingual collection of transcribed speech intended for speech technology research and development. Common Voice is designed for Automatic Speech Recognition purposes but can be useful in other domains (e.g. language identification). To achieve scale and sustainability, the Common Voice project employs crowdsourcing for both data collection and data validation. The most recent release includes 29 languages, and as of November 2019 there are a total of 38 languages collecting data. Over 50,000 individuals have participated so far, resulting in 2,500 hours of collected audio. To our knowledge this is the largest audio corpus in the public domain for speech recognition, both in terms of number of hours and number of languages. As an example use case for Common Voice, we present speech recognition experiments using Mozilla's DeepSpeech Speech-to-Text toolkit. By applying transfer learning from a source English model, we find an average Character Error Rate improvement of 5.99 ± 5.48 for twelve target languages (German, French, Italian, Turkish, Catalan, Slovenian, Welsh, Irish, Breton, Tatar, Chuvash, and Kabyle). For most of these languages, these are the first ever published results on end-to-end Automatic Speech Recognition.

Target-specific stance detection on social media, which aims at classifying a textual data instance such as a post or a comment into a stance class of a target issue, has become an emerging opinion mining paradigm of importance. An example application would be to overcome vaccine hesitancy in combating the coronavirus pandemic. However, existing stance detection strategies rely merely on the individual instances which cannot always capture the expressed stance of a given target. In response, we address a new task called conversational stance detection which is to infer the stance towards a given target (e.g., COVID-19 vaccination) when given a data instance and its corresponding conversation thread. To tackle the task, we first propose a benchmarking conversational stance detection (CSD) dataset with annotations of stances and the structures of conversation threads among the instances based on six major social media platforms in Hong Kong. To infer the desired stances from both data instances and conversation threads, we propose a model called Branch-BERT that incorporates contextual information in conversation threads. Extensive experiments on our CSD dataset show that our proposed model outperforms all the baseline models that do not make use of contextual information. Specifically, it improves the F1 score by 10.3% compared with the state-of-the-art method in the SemEval-2016 Task 6 competition. This shows the potential of incorporating rich contextual information on detecting target-specific stances on social media platforms and implies a more practical way to construct future stance detection tasks.

对于大型小分子的大型库，在考虑一系列疾病模型，测定条件和剂量范围时，详尽的组合化学筛选变得不可行。深度学习模型已实现了硅的最终技术，以预测协同得分。但是，药物组合的数据库对协同剂有偏见，这些结果不一定会概括分布不足。我们采用了使用深度学习模型的顺序模型优化搜索来快速发现与癌细胞系相比的协同药物组合，而与详尽的评估相比，筛查要少得多。在仅3轮ML引导的体外实验（包括校准圆圈）之后，我们发现，对高度协同组合进行了查询的一组药物对。进行了另外两轮ML引导实验，以确保趋势的可重复性。值得注意的是，我们重新发现药物组合后来证实将在临床试验中研究。此外，我们发现仅使用结构信息生成的药物嵌入开始反映作用机理。

船上自治技术，如规划和调度，识别科学目标和基于内容的数据摘要，将导致令人兴奋的新空间科学任务。然而，尚未研究具有此类船上自治能力的经营任务的挑战，这是足以在使命概念中考虑的细节水平。这些自主功能需要更改当前的操作流程，实践和工具。我们制定了一个案例研究，以评估使运营商和科学家通过促进地面人员和车载算法之间的共同模型来运营自主航天器所需的变化。我们评估使运营商和科学家能够向航天器传达所需的新的操作工具和工作流程，并能够重建和解释船上和航天器状态的决定。这些工具的模型用于用户学习，了解过程和工具在实现共享理解框架方面的有效性，以及在运营商和科学家有效实现特派团科学目标的能力。

最近的研究表明，神经组合优化（NCO）在许多组合优化问题（如路由）中具有优于传统算法的优点，但是对于涉及相互条件的动作空间的包装，诸如打包的更加复杂的优化任务的效率较低。在本文中，我们提出了一种经常性的条件查询学习（RCQL）方法来解决2D和3D包装问题。我们首先通过经常性编码器嵌入状态，然后采用先前操作的条件查询注意。条件查询机制填充了学习步骤之间的信息差距，将问题塑造为Markov决策过程。从复发中受益，单个RCQL模型能够处理不同尺寸的包装问题。实验结果表明，RCQL可以有效地学习用于离线和在线条带包装问题（SPP）的强烈启发式，优于空间利用率范围广泛的基线。 RCQL与最先进的方法相比，在离线2D 40盒案例中将平均箱间隙比率降低1.83％，3.84％。同时，我们的方法还实现了5.64％的空间利用率，对于1000件物品的空间利用率比现有技术更高。

我们在蒙特卡洛事件生成的生成对抗学习的背景下提出和评估一种替代量子发生器体系结构，用于模拟大型强子碰撞器（LHC）的粒子物理过程。我们通过在已知基础分布生成的人造数据上实施量子网络来验证这种方法。然后将网络应用于特定LHC散射过程的蒙特卡洛生成的数据集。新的量子生成器体系结构导致对最先进的实现的概括，即使使用浅深度网络，也可以达到较小的Kullback-Leibler分歧。此外，即使经过小型培训样本组进行了训练，量子发生器即使训练了培训，也成功地学习了基础分布功能。这对于数据增强应用程序特别有趣。我们将这种新颖的方法部署在两个不同的量子硬件体系结构，即被困的离子和超导技术上，以测试其无关紧要的可行性。

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.

We present the interpretable meta neural ordinary differential equation (iMODE) method to rapidly learn generalizable (i.e., not parameter-specific) dynamics from trajectories of multiple dynamical systems that vary in their physical parameters. The iMODE method learns meta-knowledge, the functional variations of the force field of dynamical system instances without knowing the physical parameters, by adopting a bi-level optimization framework: an outer level capturing the common force field form among studied dynamical system instances and an inner level adapting to individual system instances. A priori physical knowledge can be conveniently embedded in the neural network architecture as inductive bias, such as conservative force field and Euclidean symmetry. With the learned meta-knowledge, iMODE can model an unseen system within seconds, and inversely reveal knowledge on the physical parameters of a system, or as a Neural Gauge to "measure" the physical parameters of an unseen system with observed trajectories. We test the validity of the iMODE method on bistable, double pendulum, Van der Pol, Slinky, and reaction-diffusion systems.
