Text-based speech editing allows users to edit speech by intuitively cutting, copying, and pasting text to speed up the process of editing speech. In the previous work, CampNet (context-aware mask prediction network) is proposed to realize text-based speech editing, significantly improving the quality of edited speech. This paper aims at a new task: adding emotional effect to the editing speech during the text-based speech editing to make the generated speech more expressive. To achieve this task, we propose Emo-CampNet (emotion CampNet), which can provide the option of emotional attributes for the generated speech in text-based speech editing and has the one-shot ability to edit unseen speakers' speech. Firstly, we propose an end-to-end emotion-selectable text-based speech editing model. The key idea of the model is to control the emotion of generated speech by introducing additional emotion attributes based on the context-aware mask prediction network. Secondly, to prevent the emotion of the generated speech from being interfered by the emotional components in the original speech, a neutral content generator is proposed to remove the emotion from the original speech, which is optimized by the generative adversarial framework. Thirdly, two data augmentation methods are proposed to enrich the emotional and pronunciation information in the training set, which can enable the model to edit the unseen speaker's speech. The experimental results that 1) Emo-CampNet can effectively control the emotion of the generated speech in the process of text-based speech editing; And can edit unseen speakers' speech. 2) Detailed ablation experiments further prove the effectiveness of emotional selectivity and data augmentation methods.

Text Summarization is recognised as one of the NLP downstream tasks and it has been extensively investigated in recent years. It can assist people with perceiving the information rapidly from the Internet, including news articles, social posts, videos, etc. Most existing research works attempt to develop summarization models to produce a better output. However, advent limitations of most existing models emerge, including unfaithfulness and factual errors. In this paper, we propose a novel model, named as Knowledge-aware Abstractive Text Summarization, which leverages the advantages offered by Knowledge Graph to enhance the standard Seq2Seq model. On top of that, the Knowledge Graph triplets are extracted from the source text and utilised to provide keywords with relational information, producing coherent and factually errorless summaries. We conduct extensive experiments by using real-world data sets. The results reveal that the proposed framework can effectively utilise the information from Knowledge Graph and significantly reduce the factual errors in the summary.

Dunhuang murals are a collection of Chinese style and national style, forming a self-contained Chinese-style Buddhist art. It has very high historical and cultural value and research significance. Among them, the lines of Dunhuang murals are highly general and expressive. It reflects the character's distinctive character and complex inner emotions. Therefore, the outline drawing of murals is of great significance to the research of Dunhuang Culture. The contour generation of Dunhuang murals belongs to image edge detection, which is an important branch of computer vision, aims to extract salient contour information in images. Although convolution-based deep learning networks have achieved good results in image edge extraction by exploring the contextual and semantic features of images. However, with the enlargement of the receptive field, some local detail information is lost. This makes it impossible for them to generate reasonable outline drawings of murals. In this paper, we propose a novel edge detector based on self-attention combined with convolution to generate line drawings of Dunhuang murals. Compared with existing edge detection methods, firstly, a new residual self-attention and convolution mixed module (Ramix) is proposed to fuse local and global features in feature maps. Secondly, a novel densely connected backbone extraction network is designed to efficiently propagate rich edge feature information from shallow layers into deep layers. Compared with existing methods, it is shown on different public datasets that our method is able to generate sharper and richer edge maps. In addition, testing on the Dunhuang mural dataset shows that our method can achieve very competitive performance.

Previous databases have been designed to further the development of fake audio detection. However, fake utterances are mostly generated by altering timbre, prosody, linguistic content or channel noise of original audios. They ignore a fake situation, in which the attacker manipulates an acoustic scene of the original audio with another forgery one. It will pose a major threat to our society if some people misuse the manipulated audio with malicious purpose. Therefore, this motivates us to fill in the gap. This paper designs such a dataset for scene fake audio detection (SceneFake). A manipulated audio in the SceneFake dataset involves only tampering the acoustic scene of an utterance by using speech enhancement technologies. We can not only detect fake utterances on a seen test set but also evaluate the generalization of fake detection models to unseen manipulation attacks. Some benchmark results are described on the SceneFake dataset. Besides, an analysis of fake attacks with different speech enhancement technologies and signal-to-noise ratios are presented on the dataset. The results show that scene manipulated utterances can not be detected reliably by the existing baseline models of ASVspoof 2019. Furthermore, the detection of unseen scene manipulation audio is still challenging.

进行了许多有效的尝试进行了DeepFake音频检测。但是，他们只能区分真实和假货。对于许多实际的应用程序方案，还需要哪种工具或算法生成DeepFake音频。这提出了一个问题：我们可以检测到DeepFake音频的系统指纹吗？因此，本文进行了初步研究，以检测DeepFake音频的系统指纹。实验是从五个最新的深入学习语音合成系统的DeepFake音频数据集上进行的。结果表明，LFCC功能相对适合系统指纹检测。此外，RESNET在基于LCNN和X-Vector模型中获得了最佳检测结果。T-SNE可视化表明，不同的语音合成系统会生成不同的系统指纹。

已经进行了许多有效的尝试来进行虚假的音频检测。但是，他们只能提供检测结果，但没有对抗这种伤害的对策。对于许多相关的实际应用，也需要哪种模型或算法生成假音频。因此，我们提出了一个新问题，用于检测虚假音频的Vocoder指纹。实验是在由八个最先进的歌手合成的数据集上进行的。我们已经初步探索了功能和模型体系结构。T-SNE可视化表明，不同的Vocoder会生成不同的Vocoder指纹。

现有的假音频检测系统通常依靠专家经验来设计声学功能或手动设计网络结构的超参数。但是，人工调整参数可能会对结果产生相对明显的影响。几乎不可能手动设置最佳参数集。因此，本文提出了一种完全自动化的终端伪造音频检测方法。我们首先使用WAV2VEC预训练模型来获得语音的高级表示。此外，对于网络结构，我们使用了名为Light-Darts的可区分体系结构搜索（飞镖）的修改版本。它学习了深厚的语音表示，同时自动学习和优化包括卷积操作和残留块组成的复杂神经结构。 ASVSPOOF 2019 LA数据集的实验结果表明，我们提出的系统达到的错误率（EER）为1.08％，这表现优于最先进的单个系统。

多个实例学习（MIL）是对诊断病理学的整个幻灯片图像（WSI）进行分类的强大方法。 MIL对WSI分类的基本挑战是发现触发袋子标签的\ textit {critical Instances}。但是，先前的方法主要是在独立和相同的分布假设（\ textit {i.i.d}）下设计的，忽略了肿瘤实例或异质性之间的相关性。在本文中，我们提出了一种新颖的基于多重检测的多重实例学习（MDMIL）来解决上述问题。具体而言，MDMIL是由内部查询产生模块（IQGM）和多重检测模块（MDM）构建的，并在训练过程中基于内存的对比度损失的辅助。首先，IQGM给出了实例的概率，并通过在分布分析后汇总高度可靠的功能来为后续MDM生成内部查询（IQ）。其次，在MDM中，多重检测交叉注意（MDCA）和多头自我注意力（MHSA）合作以生成WSI的最终表示形式。在此过程中，智商和可训练的变异查询（VQ）成功建立了实例之间的联系，并显着提高了模型对异质肿瘤的鲁棒性。最后，为了进一步在特征空间中实施限制并稳定训练过程，我们采用基于内存的对比损失，即使在每次迭代中有一个样本作为输入，也可以实现WSI分类。我们对三个计算病理数据集进行实验，例如CamelyOn16，TCGA-NSCLC和TCGA-RCC数据集。优越的准确性和AUC证明了我们提出的MDMIL比其他最先进方法的优越性。

班级增量学习（CIL）吸引了很多关注，但是大多数现有相关的作品都集中在微调整个表示模型上，这不可避免地导致了许多灾难性的遗忘。相比之下，使用语义丰富的预训练的表示模型，参数 - 辅助调整（PAT）仅更改很少的参数来学习新的视觉概念。最近的研究证明，基于PAT的CIL自然可以避免像大多数现有方法一样通过重播或蒸馏而战斗。但是，我们发现基于PAT的CIL仍然面临严重的语义漂移，这是由分类器学习偏见在不同学习阶段引起的问题，这大大降低了基于PAT的CIL的性能。为了解决这个问题，我们提出了增量原型调整（IPT），这是一种简单但有效的方法，它调整了分类和学习示例原型的类别原型，以补偿语义漂移。广泛的实验表明，我们的方法可以有效地补偿语义漂移。与经过良好训练的VIT骨架和其他PAT方法相结合，IPT超过了主流学习基准的最新基准。

自主驾驶的当代深度学习对象检测方法通常会假定前缀类别的共同交通参与者，例如行人和汽车。大多数现有的探测器无法检测到罕见的物体和拐角案例（例如，越过街道的狗），这可能会导致某些情况下发生严重的事故，从而使真实世界应用可靠的自动驾驶不确定。阻碍了真正可靠的自动驾驶系统发展的主要原因是缺乏评估对象探测器在角案例上的性能的公共数据集。因此，我们介绍了一个名为CODA的具有挑战性的数据集，该数据集揭示了基于视力的检测器的关键问题。该数据集由1500个精心选择的现实世界驾驶场景组成，每个场景平均包含四个对象级角案例（平均），涵盖30多个对象类别。在CODA上，在大型自动驾驶数据集中训练的标准对象探测器的性能显着下降到3月的12.8％。此外，我们试验了最新的开放世界对象检测器，发现它也无法可靠地识别尾声中的新对象，这表明对自主驾驶的强大感知系统可能远离触及。我们希望我们的CODA数据集有助于对现实世界自动驾驶的可靠检测进行进一步的研究。我们的数据集将在https://coda-dataset.github.io上发布。
