对于诊断各种疾病的诊断，对睡眠阶段进行分类至关重要。但是，现有的自动诊断方法主要采用“金标准”局部脑图（EEG）或医院中多摄像机仪（PSG）机器的其他单型模式传感信号，这些信号昂贵，导入且因此不适合保健点监测在家。为了在家中启用睡眠阶段监控，我们在本文中分析了红外视频与脑电图信号之间的关系，并提出了一项新任务：通过将有用的知识从EEG信号提炼到视觉视频，使用红外视频对睡眠阶段进行分类。为了为该应用程序建立可靠的跨模式基准，我们开发了一个新的数据集，称为通过红外视频和脑电图（$ s^3ve $）看到您的睡眠阶段。 $ s^3ve $是一个大型数据集，包括用于睡眠阶段分类的同步红外视频和脑电图信号，包括105个主题和154,573个视频剪辑，长度超过1100小时。我们的贡献不仅限于数据集，而且还涉及一种新型的跨模式蒸馏基线模型，即结构感知的对比度蒸馏（SACD），以将脑电图知识提升为红外视频特征。 SACD在我们的$ S^3ve $和现有的跨模式蒸馏基准上都达到了最先进的表演。基准方法和基线方法都将被释放给社区。我们希望在睡眠阶段分类中提高更多注意力并促进更多的发展，更重要的是，从临床信号/媒体到传统媒体的跨模式蒸馏。

产生相同解剖结构的多对比度/模态MRI丰富了诊断信息，但由于数据获取时间过多而在实践中受到限制。在本文中，我们提出了一种新的深入学习模型，用于使用几种源模态的不完整的k空间数据作为输入，用于联合重建和合成多模式MRI。我们模型的输出包括源模式的重建图像和目标模式中合成的高质量图像。我们提出的模型被公式化为一个变异问题，该问题利用了几个可学习的特定特征提取器和多模式合成模块。我们提出了一种可学习的优化算法来求解该模型，该算法可以使用多模式MRI数据训练其参数的多相网络。此外，采用了一个二线优化框架进行鲁棒参数训练。我们使用广泛的数值实验证明了方法的有效性。

我们提出了一个基于一般学习的框架，用于解决非平滑和非凸图像重建问题。我们将正则函数建模为$ l_ {2,1} $ norm的组成，并将平滑但非convex功能映射参数化为深卷积神经网络。我们通过利用Nesterov的平滑技术和残留学习的概念来开发一种可证明的趋同的下降型算法来解决非平滑非概念最小化问题，并学习网络参数，以使算法的输出与培训数据中的参考匹配。我们的方法用途广泛，因为人们可以将各种现代网络结构用于正规化，而所得网络继承了算法的保证收敛性。我们还表明，所提出的网络是参数有效的，其性能与实践中各种图像重建问题中的最新方法相比有利。

无源的无监督域适应性（SFUDA）旨在使用未标记的目标数据和训练有素的源域模型来学习目标域模型。大多数先前的SFUDA都致力于根据源知识推断目标数据的语义。在不衡量源知识的可传递性的情况下，这些方法不足以利用源知识，并且无法识别推断的目标语义的可靠性。但是，现有的可传递性测量需要源数据或目标标签，而SFUDA中是不可行的。为此，首先，我们提出了一种新颖的不确定性诱导的可传递性表示（UTR），该表示在没有源数据和目标标签的情况下，它利用不确定性作为工具来分析源编码的通道可传递性。域级UTR揭开了编码器通道向目标域的可传输程度，实例级别的UTR表征了推断的目标语义的可靠性。其次，基于UTR，我们为SFUDA提出了一个新颖的校准自适应框架（CAF），包括i）源知识校准模块，该模块指导目标模型学习可转移的源知识并丢弃不可转移的源知识，并且II）校准不可靠语义的目标语义校准模块。在校准的源知识和目标语义的帮助下，该模型可以安全地适应目标领域。我们使用实验结果验证了方法的有效性，并证明所提出的方法在三个SFUDA基准上实现了最先进的性能。代码可在https://github.com/spiresearch/utr上找到。

现有域适应方法假设域差异是由一些离散属性和变化引起的很少的离散属性。因此，我们建议研究一个新问题，即通过连续变化的属性形成无限结构域的晶状体连续域适应（CDA）。利用两个标记的源域和几个观察到的未标记目标域数据的知识，CDA的目的是学习具有连续属性的整个数据分布的通用模型。除了提出新问题的贡献外，我们还提出了一种新颖的方法作为强大的CDA基线。具体而言，首先，我们提出了一种新颖的交替训练策略，以减少多个领域之间的差异，同时概括为看不见的目标域。其次，在估计跨域差异测量时，我们提出了连续性约束。最后，为了使差异与迷你批量大小相结合，我们设计了一个特定领域的队列，以维护源域的全局视图，从而进一步提高了适应性性能。事实证明，我们的方法可以使用广泛的实验实现CDA问题的最新问题。该代码可在https://github.com/spiresearch/cda上找到。

Masked image modeling (MIM) performs strongly in pre-training large vision Transformers (ViTs). However, small models that are critical for real-world applications cannot or only marginally benefit from this pre-training approach. In this paper, we explore distillation techniques to transfer the success of large MIM-based pre-trained models to smaller ones. We systematically study different options in the distillation framework, including distilling targets, losses, input, network regularization, sequential distillation, etc, revealing that: 1) Distilling token relations is more effective than CLS token- and feature-based distillation; 2) An intermediate layer of the teacher network as target perform better than that using the last layer when the depth of the student mismatches that of the teacher; 3) Weak regularization is preferred; etc. With these findings, we achieve significant fine-tuning accuracy improvements over the scratch MIM pre-training on ImageNet-1K classification, using all the ViT-Tiny, ViT-Small, and ViT-base models, with +4.2%/+2.4%/+1.4% gains, respectively. Our TinyMIM model of base size achieves 52.2 mIoU in AE20K semantic segmentation, which is +4.1 higher than the MAE baseline. Our TinyMIM model of tiny size achieves 79.6% top-1 accuracy on ImageNet-1K image classification, which sets a new record for small vision models of the same size and computation budget. This strong performance suggests an alternative way for developing small vision Transformer models, that is, by exploring better training methods rather than introducing inductive biases into architectures as in most previous works.

In this paper, we propose a robust 3D detector, named Cross Modal Transformer (CMT), for end-to-end 3D multi-modal detection. Without explicit view transformation, CMT takes the image and point clouds tokens as inputs and directly outputs accurate 3D bounding boxes. The spatial alignment of multi-modal tokens is performed implicitly, by encoding the 3D points into multi-modal features. The core design of CMT is quite simple while its performance is impressive. CMT obtains 73.0% NDS on nuScenes benchmark. Moreover, CMT has a strong robustness even if the LiDAR is missing. Code will be released at https://github.com/junjie18/CMT.

Dataset distillation has emerged as a prominent technique to improve data efficiency when training machine learning models. It encapsulates the knowledge from a large dataset into a smaller synthetic dataset. A model trained on this smaller distilled dataset can attain comparable performance to a model trained on the original training dataset. However, the existing dataset distillation techniques mainly aim at achieving the best trade-off between resource usage efficiency and model utility. The security risks stemming from them have not been explored. This study performs the first backdoor attack against the models trained on the data distilled by dataset distillation models in the image domain. Concretely, we inject triggers into the synthetic data during the distillation procedure rather than during the model training stage, where all previous attacks are performed. We propose two types of backdoor attacks, namely NAIVEATTACK and DOORPING. NAIVEATTACK simply adds triggers to the raw data at the initial distillation phase, while DOORPING iteratively updates the triggers during the entire distillation procedure. We conduct extensive evaluations on multiple datasets, architectures, and dataset distillation techniques. Empirical evaluation shows that NAIVEATTACK achieves decent attack success rate (ASR) scores in some cases, while DOORPING reaches higher ASR scores (close to 1.0) in all cases. Furthermore, we conduct a comprehensive ablation study to analyze the factors that may affect the attack performance. Finally, we evaluate multiple defense mechanisms against our backdoor attacks and show that our attacks can practically circumvent these defense mechanisms.

Blind image quality assessment (BIQA) remains challenging due to the diversity of distortion and image content variation, which complicate the distortion patterns crossing different scales and aggravate the difficulty of the regression problem for BIQA. However, existing BIQA methods often fail to consider multi-scale distortion patterns and image content, and little research has been done on learning strategies to make the regression model produce better performance. In this paper, we propose a simple yet effective Progressive Multi-Task Image Quality Assessment (PMT-IQA) model, which contains a multi-scale feature extraction module (MS) and a progressive multi-task learning module (PMT), to help the model learn complex distortion patterns and better optimize the regression issue to align with the law of human learning process from easy to hard. To verify the effectiveness of the proposed PMT-IQA model, we conduct experiments on four widely used public datasets, and the experimental results indicate that the performance of PMT-IQA is superior to the comparison approaches, and both MS and PMT modules improve the model's performance.

Automatic music generation with artificial intelligence typically requires a large amount of data which is hard to obtain for many less common genres and musical instruments. To tackle this issue, we present ongoing work and preliminary findings on the possibility for deep models to transfer knowledge from language to music, by finetuning large language models pre-trained on a massive text corpus on only hundreds of MIDI files of drum performances. We show that by doing so, one of the largest, state-of-the-art models (GPT3) is capable of generating reasonable drum grooves, while models that are not pre-trained (Transformer) shows no such ability beyond naive repetition. Evaluating generated music is a challenging task, more so is evaluating drum grooves with little precedence in literature. Hence, we propose a tailored structural evaluation method and analyze drum grooves produced by GPT3 compared to those played by human professionals, exposing the strengths and weaknesses of such generation by language-to-music transfer. Our findings suggest that language-to-music transfer learning with large language models is viable and promising.
