提供有关学习者论证的反馈对于发展批判性思维技能至关重要，但是，它需要大量的时间和精力。为了减轻教师的过载，我们旨在自动化提供反馈的过程，尤其是给出诊断评论，以指出论点固有的弱点。建议给出特定的诊断评论，以便学习者可以识别诊断而不会误解。但是，如何制定提供特定的诊断评论的任务并不明显。我们将任务的表述作为模板选择和插槽填充，以使自动评估变得更加容易，并且模型的行为更加可行。该公式的关键是创建足以实用的模板集的可能性。在本文中，我们定义了三个标准，即模板集应满足：表达性，信息性和唯一性，并验证创建一个满足这些标准作为第一个试验的模板集的可行性。我们将通过一项注释研究证明，将文本中给出的诊断评论转换为模板格式是可行的。注释研究中使用的语料库公开可用。

We propose a Cascaded Buffered IoU (C-BIoU) tracker to track multiple objects that have irregular motions and indistinguishable appearances. When appearance features are unreliable and geometric features are confused by irregular motions, applying conventional Multiple Object Tracking (MOT) methods may generate unsatisfactory results. To address this issue, our C-BIoU tracker adds buffers to expand the matching space of detections and tracks, which mitigates the effect of irregular motions in two aspects: one is to directly match identical but non-overlapping detections and tracks in adjacent frames, and the other is to compensate for the motion estimation bias in the matching space. In addition, to reduce the risk of overexpansion of the matching space, cascaded matching is employed: first matching alive tracks and detections with a small buffer, and then matching unmatched tracks and detections with a large buffer. Despite its simplicity, our C-BIoU tracker works surprisingly well and achieves state-of-the-art results on MOT datasets that focus on irregular motions and indistinguishable appearances. Moreover, the C-BIoU tracker is the dominant component for our 2-nd place solution in the CVPR'22 SoccerNet MOT and ECCV'22 MOTComplex DanceTrack challenges. Finally, we analyze the limitation of our C-BIoU tracker in ablation studies and discuss its application scope.

This is our 2nd-place solution for the ECCV 2022 Multiple People Tracking in Group Dance Challenge. Our method mainly includes two steps: online short-term tracking using our Cascaded Buffer-IoU (C-BIoU) Tracker, and, offline long-term tracking using appearance feature and hierarchical clustering. Our C-BIoU tracker adds buffers to expand the matching space of detections and tracks, which mitigates the effect of irregular motions in two aspects: one is to directly match identical but non-overlapping detections and tracks in adjacent frames, and the other is to compensate for the motion estimation bias in the matching space. In addition, to reduce the risk of overexpansion of the matching space, cascaded matching is employed: first matching alive tracks and detections with a small buffer, and then matching unmatched tracks and detections with a large buffer. After using our C-BIoU for online tracking, we applied the offline refinement introduced by ReMOTS.

This is our second-place solution for CVPR 2022 SoccerNet Tracking Challenge. Our method mainly includes two steps: online short-term tracking using our Cascaded Buffer-IoU (C-BIoU) Tracker, and, offline long-term tracking using appearance feature and hierarchical clustering. At each step, online tracking yielded HOTA scores near 90, and offline tracking further improved HOTA scores to around 93.2.

来自重力波检测器的数据中出现的瞬态噪声通常会引起问题，例如检测器的不稳定性以及重叠或模仿重力波信号。由于瞬态噪声被认为与环境和工具相关联，因此其分类将有助于理解其起源并改善探测器的性能。在先前的研究中，提出了用于使用时频2D图像（频谱图）进行瞬态噪声进行分类的体系结构，该架构使用了无监督的深度学习与变异自动编码器和不变信息集群的结合。提出的无监督学习结构应用于重力间谍数据集，该数据集由高级激光干涉仪重力波动台（Advanced Ligo）瞬态噪声与其相关元数据进行讨论，以讨论在线或离线数据分析的潜力。在这项研究的重点是重力间谍数据集中，研究并报告了先前研究的无监督学习结构的训练过程。

It is well-known that typical word embedding methods such as Word2Vec and GloVe have the property that the meaning can be composed by adding up the embeddings (additive compositionality). Several theories have been proposed to explain additive compositionality, but the following questions remain unanswered: (Q1) The assumptions of those theories do not hold for the practical word embedding. (Q2) Ordinary additive compositionality can be seen as an AND operation of word meanings, but it is not well understood how other operations, such as OR and NOT, can be computed by the embeddings. We address these issues by the idea of frequency-weighted centering at its core. This paper proposes a post-processing method for bridging the gap between practical word embedding and the assumption of theory about additive compositionality as an answer to (Q1). It also gives a method for taking OR or NOT of the meaning by linear operation of word embedding as an answer to (Q2). Moreover, we confirm experimentally that the accuracy of AND operation, i.e., the ordinary additive compositionality, can be improved by our post-processing method (3.5x improvement in top-100 accuracy) and that OR and NOT operations can be performed correctly.

我们培训了深度神经网络（DNN）作为中微子能量密度，助熔剂和流体速度的函数，以再现在我们的第一原理核心崩溃超新星（CCSN）模拟中获得的Eddington Tensor。虽然是中微子运输的最流行近似的矩的方法需要闭合关系，但文献中通常采用的分析闭合关系都没有捕获动量空间中的中微子角分布的所有方面。在本文中，我们通过使用将中微子能量密度，磁通量和流体速度作为输入和埃丁顿张量作为输出来开发闭合关系。我们考虑两种DNN：传统的DNN命名为组分 - 明智的神经网络（CWNN）和张力基神经网络（TBNN）。我们发现，埃丁顿张量的对角线组件由DNN比M1封闭关系更好地再现，特别是对于低到中间能量。对于非对角线组件，DNN与Boltzmann求解器更好地达到比大半径的M1闭合更好。在两个DNN之间的比较中，TBNN具有比CWNN稍微更好的性能。通过基于DNN的新的封闭关系，该DNN良好地重现Eddington Tensor的成本更小，我们为瞬间方法开辟了一种新的可能性。
