知识图完成（KGC）旨在发现知识图（KGS）中实体之间的缺失关系。大多数先前的KGC工作都集中在实体和关系的学习表现上。然而，通常需要更高维度的嵌入空间才能获得更好的推理能力，这会导致更大的模型大小，并阻碍对现实世界中的问题的适用性（例如，大规模kgs或移动/边缘计算）。在这项工作中提出了一种称为GreenKGC的轻型模块化的KGC解决方案，以解决此问题。 GreenKGC由三个模块组成：1）表示学习，2）特征修剪和3）决策学习。在模块1中，我们利用现有的KG嵌入模型来学习实体和关系的高维表示。在模块2中，KG分为几个关系组，然后分为一个特征修剪过程，以找到每个关系组的最判别特征。最后，将分类器分配给每个关系组，以应对模块3中KGC任务的低维三功能原始的高维嵌入型号尺寸较小。此外，我们对两个三重分类数据集进行了实验，以证明相同的方法可以推广到更多任务。

翻译，旋转和缩放是图像处理中三个常用的几何操作操作。此外，其中一些成功用于开发有效的知识图嵌入（KGE）模型，例如transe和旋转。受协同作用的启发，我们通过利用这项工作中的所有三项操作提出了一个新的KGE模型。由于翻译，旋转和缩放操作被级联形成一个复合的操作，因此新模型被命名为复合。通过在小组理论的框架中铸造复合物，我们表明，基于得分功能的KGE模型是复合的特殊情况。Compounde将简单的基于距离的关系扩展到与关系有关的化合物操作上的头部和/或尾部实体。为了证明化合物的有效性，我们对三个流行的KG完成数据集进行了实验。实验结果表明，复合者始终达到了现状的性能。

实体类型预测是知识图中的一个重要问题（kg）研究。在这项工作中提出了一种新的KG实体类型预测方法，名为Core（复杂的空间回归和嵌入）。所提出的核心方法利用两个复杂空间嵌入模型的表现力;即，旋转和复杂的模型。它使用旋转或复杂地将实体和类型嵌入两个不同的复杂空间中。然后，我们推导了一个复杂的回归模型来链接这两个空格。最后，介绍了一种优化嵌入和回归参数的机制。实验表明，核心优于代表性KG实体型推理数据集的基准测试方法。分析了各种实体型预测方法的强度和弱点。

知识库完成在这项工作中被制定为二进制分类问题，其中使用知识图中的相关链接（KGS）培训XGBoost二进制分类器。新方法名为KGBoost，采用模块化设计，并尝试找到硬阴性样本，以便培训强大的分类器以进行缺失链路预测。我们在多个基准数据集中进行实验，并证明KGBoost在大多数数据集中优于最先进的方法。此外，与端到端优化训练的模型相比，kgboost在低维设置下运行良好，以便允许更小的型号尺寸。

As natural language processing (NLP) for gender bias becomes a significant interdisciplinary topic, the prevalent data-driven techniques such as large-scale language models suffer from data inadequacy and biased corpus, especially for languages with insufficient resources such as Chinese. To this end, we propose a Chinese cOrpus foR Gender bIas Probing and Mitigation CORGI-PM, which contains 32.9k sentences with high-quality labels derived by following an annotation scheme specifically developed for gender bias in the Chinese context. Moreover, we address three challenges for automatic textual gender bias mitigation, which requires the models to detect, classify, and mitigate textual gender bias. We also conduct experiments with state-of-the-art language models to provide baselines. To our best knowledge, CORGI-PM is the first sentence-level Chinese corpus for gender bias probing and mitigation.

We present Second Thought, a new learning paradigm that enables language models (LMs) to re-align with human values. By modeling the chain-of-edits between value-unaligned and value-aligned text, with LM fine-tuning and additional refinement through reinforcement learning, Second Thought not only achieves superior performance in three value alignment benchmark datasets but also shows strong human-value transfer learning ability in few-shot scenarios. The generated editing steps also offer better interpretability and ease for interactive error correction. Extensive human evaluations further confirm its effectiveness.

Three-dimensional (3D) ultrasound imaging technique has been applied for scoliosis assessment, but current assessment method only uses coronal projection image and cannot illustrate the 3D deformity and vertebra rotation. The vertebra detection is essential to reveal 3D spine information, but the detection task is challenging due to complex data and limited annotations. We propose VertMatch, a two-step framework to detect vertebral structures in 3D ultrasound volume by utilizing unlabeled data in semi-supervised manner. The first step is to detect the possible positions of structures on transverse slice globally, and then the local patches are cropped based on detected positions. The second step is to distinguish whether the patches contain real vertebral structures and screen the predicted positions from the first step. VertMatch develops three novel components for semi-supervised learning: for position detection in the first step, (1) anatomical prior is used to screen pseudo labels generated from confidence threshold method; (2) multi-slice consistency is used to utilize more unlabeled data by inputting multiple adjacent slices; (3) for patch identification in the second step, the categories are rebalanced in each batch to solve imbalance problem. Experimental results demonstrate that VertMatch can detect vertebra accurately in ultrasound volume and outperforms state-of-the-art methods. VertMatch is also validated in clinical application on forty ultrasound scans, and it can be a promising approach for 3D assessment of scoliosis.

To reproduce the success of text-to-image (T2I) generation, recent works in text-to-video (T2V) generation employ large-scale text-video dataset for fine-tuning. However, such paradigm is computationally expensive. Humans have the amazing ability to learn new visual concepts from just one single exemplar. We hereby study a new T2V generation problem$\unicode{x2014}$One-Shot Video Generation, where only a single text-video pair is presented for training an open-domain T2V generator. Intuitively, we propose to adapt the T2I diffusion model pretrained on massive image data for T2V generation. We make two key observations: 1) T2I models are able to generate images that align well with the verb terms; 2) extending T2I models to generate multiple images concurrently exhibits surprisingly good content consistency. To further learn continuous motion, we propose Tune-A-Video with a tailored Sparse-Causal Attention, which generates videos from text prompts via an efficient one-shot tuning of pretrained T2I diffusion models. Tune-A-Video is capable of producing temporally-coherent videos over various applications such as change of subject or background, attribute editing, style transfer, demonstrating the versatility and effectiveness of our method.

We introduce \textsc{PoliteRewrite} -- a dataset for polite language rewrite which is a novel sentence rewrite task. Compared with previous text style transfer tasks that can be mostly addressed by slight token- or phrase-level edits, polite language rewrite requires deep understanding and extensive sentence-level edits over an offensive and impolite sentence to deliver the same message euphemistically and politely, which is more challenging -- not only for NLP models but also for human annotators to rewrite with effort. To alleviate the human effort for efficient annotation, we first propose a novel annotation paradigm by a collaboration of human annotators and GPT-3.5 to annotate \textsc{PoliteRewrite}. The released dataset has 10K polite sentence rewrites annotated collaboratively by GPT-3.5 and human, which can be used as gold standard for training, validation and test; and 100K high-quality polite sentence rewrites by GPT-3.5 without human review. We wish this work (The dataset (10K+100K) will be released soon) could contribute to the research on more challenging sentence rewrite, and provoke more thought in future on resource annotation paradigm with the help of the large-scaled pretrained models.

Summary quality assessment metrics have two categories: reference-based and reference-free. Reference-based metrics are theoretically more accurate but are limited by the availability and quality of the human-written references, which are both difficulty to ensure. This inspires the development of reference-free metrics, which are independent from human-written references, in the past few years. However, existing reference-free metrics cannot be both zero-shot and accurate. In this paper, we propose a zero-shot but accurate reference-free approach in a sneaky way: feeding documents, based upon which summaries generated, as references into reference-based metrics. Experimental results show that this zero-shot approach can give us the best-performing reference-free metrics on nearly all aspects on several recently-released datasets, even beating reference-free metrics specifically trained for this task sometimes. We further investigate what reference-based metrics can benefit from such repurposing and whether our additional tweaks help.
