为了为视频产生适当的标题，推理需要确定相关的概念并注意它们之间的空间关系以及剪辑中的时间发展。我们的端到端编码器视频字幕框架结合了两个基于变压器的体系结构，这是一种用于单个关节时空视频分析的改编变压器，以及用于高级文本生成的基于自我注意力的解码器。此外，我们引入了一种自适应框架选择方案，以减少所需的传入帧数，同时在训练两个变压器时保持相关内容。此外，我们通过汇总每个样本的所有基础真理标题来估计与视频字幕相关的语义概念。我们的方法在MSVD以及大规模的MSR-VTT和VATEX基准数据集上实现了最新的结果，并考虑了多个自然语言产生（NLG）指标。对多样性得分的其他评估突出了我们生成的标题结构的表现力和多样性。

Reading comprehension of legal text can be a particularly challenging task due to the length and complexity of legal clauses and a shortage of expert-annotated datasets. To address this challenge, we introduce the Merger Agreement Understanding Dataset (MAUD), an expert-annotated reading comprehension dataset based on the American Bar Association's 2021 Public Target Deal Points Study, with over 39,000 examples and over 47,000 total annotations. Our fine-tuned Transformer baselines show promising results, with models performing well above random on most questions. However, on a large subset of questions, there is still room for significant improvement. As the only expert-annotated merger agreement dataset, MAUD is valuable as a benchmark for both the legal profession and the NLP community.

Recently, learning-based controllers have been shown to push mobile robotic systems to their limits and provide the robustness needed for many real-world applications. However, only classical optimization-based control frameworks offer the inherent flexibility to be dynamically adjusted during execution by, for example, setting target speeds or actuator limits. We present a framework to overcome this shortcoming of neural controllers by conditioning them on an auxiliary input. This advance is enabled by including a feature-wise linear modulation layer (FiLM). We use model-free reinforcement-learning to train quadrotor control policies for the task of navigating through a sequence of waypoints in minimum time. By conditioning the policy on the maximum available thrust or the viewing direction relative to the next waypoint, a user can regulate the aggressiveness of the quadrotor's flight during deployment. We demonstrate in simulation and in real-world experiments that a single control policy can achieve close to time-optimal flight performance across the entire performance envelope of the robot, reaching up to 60 km/h and 4.5g in acceleration. The ability to guide a learned controller during task execution has implications beyond agile quadrotor flight, as conditioning the control policy on human intent helps safely bringing learning based systems out of the well-defined laboratory environment into the wild.

Double-blind peer review is considered a pillar of academic research because it is perceived to ensure a fair, unbiased, and fact-centered scientific discussion. Yet, experienced researchers can often correctly guess from which research group an anonymous submission originates, biasing the peer-review process. In this work, we present a transformer-based, neural-network architecture that only uses the text content and the author names in the bibliography to atttribute an anonymous manuscript to an author. To train and evaluate our method, we created the largest authorship-identification dataset to date. It leverages all research papers publicly available on arXiv amounting to over 2 million manuscripts. In arXiv-subsets with up to 2,000 different authors, our method achieves an unprecedented authorship attribution accuracy, where up to 95% of papers are attributed correctly. Thanks to our method, we are not only able to predict the author of an anonymous work but we also identify weaknesses of the double-blind review process by finding the key aspects that make a paper attributable. We believe that this work gives precious insights into how a submission can remain anonymous in order to support an unbiased double-blind review process.

Standard language model training employs gold human documents or human-human interaction data, and treats all training data as positive examples. Growing evidence shows that even with very large amounts of positive training data, issues remain that can be alleviated with relatively small amounts of negative data -- examples of what the model should not do. In this work, we propose a novel procedure to train with such data called the CRINGE loss (ContRastive Iterative Negative GEneration). We show the effectiveness of this approach across three different experiments on the tasks of safe generation, contradiction avoidance, and open-domain dialogue. Our models outperform multiple strong baselines and are conceptually simple, easy to train and implement.

The use of multilingual language models for tasks in low and high-resource languages has been a success story in deep learning. In recent times, Arabic has been receiving widespread attention on account of its dialectal variance. While prior research studies have tried to adapt these multilingual models for dialectal variants of Arabic, it still remains a challenging problem owing to the lack of sufficient monolingual dialectal data and parallel translation data of such dialectal variants. It remains an open problem on whether the limited dialectical data can be used to improve the models trained in Arabic on its dialectal variants. First, we show that multilingual-BERT (mBERT) incrementally pretrained on Arabic monolingual data takes less training time and yields comparable accuracy when compared to our custom monolingual Arabic model and beat existing models (by an avg metric of +$6.41$). We then explore two continual pre-training methods-- (1) using small amounts of dialectical data for continual finetuning and (2) parallel Arabic to English data and a Translation Language Modeling loss function. We show that both approaches help improve performance on dialectal classification tasks ($+4.64$ avg. gain) when used on monolingual models.

We present a new NLP task and dataset from the domain of the U.S. civil procedure. Each instance of the dataset consists of a general introduction to the case, a particular question, and a possible solution argument, accompanied by a detailed analysis of why the argument applies in that case. Since the dataset is based on a book aimed at law students, we believe that it represents a truly complex task for benchmarking modern legal language models. Our baseline evaluation shows that fine-tuning a legal transformer provides some advantage over random baseline models, but our analysis reveals that the actual ability to infer legal arguments remains a challenging open research question.

在许多现实世界中，当不二维测量值时，可能会提供自由旋转3D刚体（例如卫星）的图像观察。但是，图像数据的高维度排除了学习动力学和缺乏解释性的使用，从而降低了标准深度学习方法的有用性。在这项工作中，我们提出了一个物理知识的神经网络模型，以估计和预测图像序列中的3D旋转动力学。我们使用多阶段预测管道实现了这一目标，该管道将单个图像映射到潜在表示同构为$ \ Mathbf {so}（3）$，从潜在对计算角速度，并使用Hamiltonian Motion使用Hamiltonian运动方程来预测未来的潜在状态博学的哈密顿人的代表。我们证明了方法对新的旋转刚体数据集的功效，该数据集具有旋转立方体和矩形棱镜序列，并具有均匀且不均匀的密度。

ICECUBE是一种用于检测1 GEV和1 PEV之间大气和天体中微子的光学传感器的立方公斤阵列，该阵列已部署1.45 km至2.45 km的南极的冰盖表面以下1.45 km至2.45 km。来自ICE探测器的事件的分类和重建在ICeCube数据分析中起着核心作用。重建和分类事件是一个挑战，这是由于探测器的几何形状，不均匀的散射和冰中光的吸收，并且低于100 GEV的光，每个事件产生的信号光子数量相对较少。为了应对这一挑战，可以将ICECUBE事件表示为点云图形，并将图形神经网络（GNN）作为分类和重建方法。 GNN能够将中微子事件与宇宙射线背景区分开，对不同的中微子事件类型进行分类，并重建沉积的能量，方向和相互作用顶点。基于仿真，我们提供了1-100 GEV能量范围的比较与当前ICECUBE分析中使用的当前最新最大似然技术，包括已知系统不确定性的影响。对于中微子事件分类，与当前的IceCube方法相比，GNN以固定的假阳性速率（FPR）提高了信号效率的18％。另外，GNN在固定信号效率下将FPR的降低超过8（低于半百分比）。对于能源，方向和相互作用顶点的重建，与当前最大似然技术相比，分辨率平均提高了13％-20％。当在GPU上运行时，GNN能够以几乎是2.7 kHz的中位数ICECUBE触发速率的速率处理ICECUBE事件，这打开了在在线搜索瞬态事件中使用低能量中微子的可能性。

前列腺活检和图像引导的治疗程序通常是在与磁共振图像（MRI）的超声指导下进行的。准确的图像融合依赖于超声图像上前列腺的准确分割。然而，超声图像中降低的信噪比和工件（例如，斑点和阴影）限制了自动前列腺分割技术的性能，并将这些方法推广到新的图像域是本质上很难的。在这项研究中，我们通过引入一种新型的2.5D深神经网络来解决这些挑战，用于超声图像上的前列腺分割。我们的方法通过组合有监督的域适应技术和知识蒸馏损失，解决了转移学习和填充方法的局限性（即，在更新模型权重时，在更新模型权重时的性能下降）。知识蒸馏损失允许保留先前学习的知识，并在新数据集上的模型填充后降低性能下降。此外，我们的方法依赖于注意模块，该模块认为模型特征定位信息以提高分割精度。我们对一个机构的764名受试者进行了培训，并仅使用后续机构中的十个受试者对我们的模型进行了审核。我们分析了方法在三个大型数据集上的性能，其中包括来自三个不同机构的2067名受试者。我们的方法达到了平均骰子相似性系数（骰子）为$ 94.0 \ pm0.03 $，而Hausdorff距离（HD95）为2.28 $ mm $，在第一机构的独立受试者中。此外，我们的模型在其他两个机构的研究中都很好地概括了（骰子：$ 91.0 \ pm0.03 $; hd95：3.7 $ mm $ and Dice：$ 82.0 \ pm0.03 $; hd95 $; hd95：7.1 $ mm $）。
