我们提出了一个健壮而快速的捆绑调整解决方案，该解决方案估计了基于滚动快门（RS）摄像头的测量值的摄像机的6多杆姿势和环境的几何形状。这解决了现有作品中的挑战，即依靠其他传感器，高帧速率视频作为输入，对摄像机运动的限制性假设，读出方向和效率低下。为此，我们首先研究了标准化对图像点对RSBA性能的影响，并在建模真正的6-DOF相机运动时显示了更好的近似值。然后，我们为视觉残差协方差提出了一个新的分析模型，该模型可用于在优化过程中标准化再投影误差，从而提高了整体准确性。更重要的是，RSBA（NW-RSBA）中归一化和协方差标准化加权的组合可以避免常见的平面退化，而无需限制拍摄方式。此外，我们根据其Jacobian Matrix和Schur补充的稀疏性提出了NW-RSBA的加速策略。广泛的合成和真实数据实验验证了拟议解决方案对最新作品的有效性和效率。我们还证明了所提出的方法可以轻松实施，并作为已完成的RSSFM和RSSLAM解决方案插入著名的GSSFM和GSSLAM系统。

从点云数据进行分割至关重要，例如遥感，移动机器人或自动驾驶汽车。但是，由3D范围传感器捕获的点云通常是稀疏且非结构化的，具有挑战性的有效分割。在本文中，我们提出了一个快速解决方案，以对云实例进行分割，并具有较小的计算需求。为此，我们提出了一种新颖的快速欧几里得聚类（FEC）算法，该算法在现有作品中使用的聚类方案上应用了一个方案。我们的方法在概念上是简单，易于实现的（C ++中的40行），并且在产生高质量的结果的同时，针对经典分割方法实现了两个大小。

生成对抗网络的广泛应用受益于成功的训练方法，保证对象功能会聚到本地最小值。然而，由于基于梯度的方式的循环行为和基于Hessian矩阵的这些方法的昂贵计算成本，设计了高效竞争的训练方法仍然是一个具有挑战性的任务。本文提出了自适应复合梯度（ACG）方法，在合适的设置下线性收敛。理论和玩具功能实验表明，我们的方法可以缓解循环行为，并比最近提出的算法更快地收敛。值得注意的是，ACG方法不仅用于在双线性游戏以及一般游戏中找到稳定的固定点。 ACG方法是一种新的半渐变算法，因为它不需要计算每个步骤的梯度，通过利用未来迭代中的预测信息来降低梯度和黑森州的计算成本。我们通过将ACG与线性GANS集成到现有算法来进行高斯实验的两种混合。结果显示ACG与先前的算法具有竞争力。具有DCGANS的四个普遍数据集（Mnist，Fashion-Mnist，CIFAR-10和Celeba）的现实实验表明我们的ACG方法优于多个基线，说明了我们方法的优越性和功效。

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.

Few Shot Instance Segmentation (FSIS) requires models to detect and segment novel classes with limited several support examples. In this work, we explore a simple yet unified solution for FSIS as well as its incremental variants, and introduce a new framework named Reference Twice (RefT) to fully explore the relationship between support/query features based on a Transformer-like framework. Our key insights are two folds: Firstly, with the aid of support masks, we can generate dynamic class centers more appropriately to re-weight query features. Secondly, we find that support object queries have already encoded key factors after base training. In this way, the query features can be enhanced twice from two aspects, i.e., feature-level and instance-level. In particular, we firstly design a mask-based dynamic weighting module to enhance support features and then propose to link object queries for better calibration via cross-attention. After the above steps, the novel classes can be improved significantly over our strong baseline. Additionally, our new framework can be easily extended to incremental FSIS with minor modification. When benchmarking results on the COCO dataset for FSIS, gFSIS, and iFSIS settings, our method achieves a competitive performance compared to existing approaches across different shots, e.g., we boost nAP by noticeable +8.2/+9.4 over the current state-of-the-art FSIS method for 10/30-shot. We further demonstrate the superiority of our approach on Few Shot Object Detection. Code and model will be available.
