Panoptic Part Segmentation (PPS) unifies panoptic segmentation and part segmentation into one task. Previous works utilize separated approaches to handle thing, stuff, and part predictions without shared computation and task association. We aim to unify these tasks at the architectural level, designing the first end-to-end unified framework named Panoptic-PartFormer. Moreover, we find the previous metric PartPQ biases to PQ. To handle both issues, we make the following contributions: Firstly, we design a meta-architecture that decouples part feature and things/stuff feature, respectively. We model things, stuff, and parts as object queries and directly learn to optimize all three forms of prediction as a unified mask prediction and classification problem. We term our model as Panoptic-PartFormer. Secondly, we propose a new metric Part-Whole Quality (PWQ) to better measure such task from both pixel-region and part-whole perspectives. It can also decouple the error for part segmentation and panoptic segmentation. Thirdly, inspired by Mask2Former, based on our meta-architecture, we propose Panoptic-PartFormer++ and design a new part-whole cross attention scheme to further boost part segmentation qualities. We design a new part-whole interaction method using masked cross attention. Finally, the extensive ablation studies and analysis demonstrate the effectiveness of both Panoptic-PartFormer and Panoptic-PartFormer++. Compared with previous Panoptic-PartFormer, our Panoptic-PartFormer++ achieves 2% PartPQ and 3% PWQ improvements on the Cityscapes PPS dataset and 5% PartPQ on the Pascal Context PPS dataset. On both datasets, Panoptic-PartFormer++ achieves new state-of-the-art results with a significant cost drop of 70% on GFlops and 50% on parameters. Our models can serve as a strong baseline and aid future research in PPS. Code will be available.

以前的多任务密集预测研究开发了复杂的管道，例如在多个阶段进行多模式蒸馏或为每个任务寻找任务关系上下文。这些方法以外的核心洞察力是最大程度地利用每个任务之间的相互作用。受到最近基于查询的变压器的启发，我们提出了一条更简单的管道，称为Multi-Querti-Transformer（MQTRANSFORMER），该管道配备了来自不同任务的多个查询，以促进多个任务之间的推理并简化交叉任务管道。我们没有在不同任务之间建模每个像素上下文的密集上下文，而是寻求特定于任务的代理，以通过每个查询编码与任务相关的上下文进行编码的多个查询执行交叉任务推理。 MQTRANSFORMER由三个关键组件组成：共享编码器，交叉任务注意和共享解码器。我们首先将每个任务与任务相关且具有比例意识的查询对每个任务进行建模，然后将功能提取器的图像功能输出和与任务相关的查询功能都馈入共享编码器，从而从图像功能中编码查询功能。其次，我们设计了一个交叉任务注意模块，以从两个角度来推理多个任务和特征量表之间的依赖项，包括相同尺度的不同任务和同一任务的不同尺度。然后，我们使用共享解码器逐渐使用来自不同任务的合理查询功能来逐步完善图像功能。对两个密集的预测数据集（NYUD-V2和Pascal-Context）的广泛实验结果表明，该方法是一种有效的方法，并实现了最新结果。

最近提出的深度感知视频Panoptic分段（DVPS）旨在预测视频中的Panoptic分段结果和深度映射，这是一个具有挑战性的场景理解问题。在本文中，我们提供了多相变压器，揭示了DVPS任务下的所有子任务。我们的方法通过基于查询的学习探讨了深度估计与Panoptic分割的关系。特别是，我们设计三个不同的查询，包括查询，填写询问和深度查询的东西。然后我们建议通过门控融合来学习这些查询之间的相关性。从实验中，我们从深度估计和Panoptic分割方面证明了我们设计的好处。由于每个物品查询还对实例信息进行了编码，因此通过具有外观学习的裁剪实例掩码功能来执行跟踪是自然的。我们的方法在ICCV-2021 BMTT挑战视频+深度轨道上排名第一。据报道，消融研究表明我们如何提高性能。代码将在https://github.com/harboryuan/polyphonicformer提供。

估计可驱动表面和周围环境的3D结构是辅助和自主驾驶的重要任务。通过使用昂贵的3D传感器（例如LIDAR）或通过深度学习预测点深度来常见的是。而不是遵循现有的方法，我们提出道路平面视差关注网络（RPANET），这是一种基于平面视差的单眼图像序列的新型神经网络，这是驾驶场景中常见的道路平面几何形状的充分优势。 RPANET需要一对图像由道路平面的定址为对齐的图像，作为输入，输出3D重建的$ \ Gamma $地图。除了估计深度或高度之外，$ \ Gamma $ MAP的可能性在两个连续帧之间构造二维变换，同时可以容易地导出深度或高度。通过使用道路平面作为参考的连续帧，可以从平面视差和残余图像位移估计3D结构。此外，为了使网络更好地了解由平面视差引起的位移，我们引入了一种新颖的跨关注模块。我们从Waymo Open DataSet中示机数据并构建与平面视差相关的数据。在采样的数据集上进行综合实验，以展示我们在具有挑战性的情况下的方法的三维重建准确性。

Graph Neural Networks (GNNs) have shown satisfying performance on various graph learning tasks. To achieve better fitting capability, most GNNs are with a large number of parameters, which makes these GNNs computationally expensive. Therefore, it is difficult to deploy them onto edge devices with scarce computational resources, e.g., mobile phones and wearable smart devices. Knowledge Distillation (KD) is a common solution to compress GNNs, where a light-weighted model (i.e., the student model) is encouraged to mimic the behavior of a computationally expensive GNN (i.e., the teacher GNN model). Nevertheless, most existing GNN-based KD methods lack fairness consideration. As a consequence, the student model usually inherits and even exaggerates the bias from the teacher GNN. To handle such a problem, we take initial steps towards fair knowledge distillation for GNNs. Specifically, we first formulate a novel problem of fair knowledge distillation for GNN-based teacher-student frameworks. Then we propose a principled framework named RELIANT to mitigate the bias exhibited by the student model. Notably, the design of RELIANT is decoupled from any specific teacher and student model structures, and thus can be easily adapted to various GNN-based KD frameworks. We perform extensive experiments on multiple real-world datasets, which corroborates that RELIANT achieves less biased GNN knowledge distillation while maintaining high prediction utility.

To generate high quality rendering images for real time applications, it is often to trace only a few samples-per-pixel (spp) at a lower resolution and then supersample to the high resolution. Based on the observation that the rendered pixels at a low resolution are typically highly aliased, we present a novel method for neural supersampling based on ray tracing 1/4-spp samples at the high resolution. Our key insight is that the ray-traced samples at the target resolution are accurate and reliable, which makes the supersampling an interpolation problem. We present a mask-reinforced neural network to reconstruct and interpolate high-quality image sequences. First, a novel temporal accumulation network is introduced to compute the correlation between current and previous features to significantly improve their temporal stability. Then a reconstruct network based on a multi-scale U-Net with skip connections is adopted for reconstruction and generation of the desired high-resolution image. Experimental results and comparisons have shown that our proposed method can generate higher quality results of supersampling, without increasing the total number of ray-tracing samples, over current state-of-the-art methods.

An increasing number of public datasets have shown a marked clinical impact on assessing anatomical structures. However, each of the datasets is small, partially labeled, and rarely investigates severe tumor subjects. Moreover, current models are limited to segmenting specific organs/tumors, which can not be extended to novel domains and classes. To tackle these limitations, we introduce embedding learned from Contrastive Language-Image Pre-training (CLIP) to segmentation models, dubbed the CLIP-Driven Universal Model. The Universal Model can better segment 25 organs and 6 types of tumors by exploiting the semantic relationship between abdominal structures. The model is developed from an assembly of 14 datasets with 3,410 CT scans and evaluated on 6,162 external CT scans from 3 datasets. We rank first on the public leaderboard of the Medical Segmentation Decathlon (MSD) and achieve the state-of-the-art results on Beyond The Cranial Vault (BTCV). Compared with dataset-specific models, the Universal Model is computationally more efficient (6x faster), generalizes better to CT scans from varying sites, and shows stronger transfer learning performance on novel tasks. The design of CLIP embedding enables the Universal Model to be easily extended to new classes without catastrophically forgetting the previously learned classes.

This paper illustrates the technologies of user next intent prediction with a concept knowledge graph. The system has been deployed on the Web at Alipay, serving more than 100 million daily active users. Specifically, we propose AlipayKG to explicitly characterize user intent, which is an offline concept knowledge graph in the Life-Service domain modeling the historical behaviors of users, the rich content interacted by users and the relations between them. We further introduce a Transformer-based model which integrates expert rules from the knowledge graph to infer the online user's next intent. Experimental results demonstrate that the proposed system can effectively enhance the performance of the downstream tasks while retaining explainability.

Medical image segmentation (MIS) is essential for supporting disease diagnosis and treatment effect assessment. Despite considerable advances in artificial intelligence (AI) for MIS, clinicians remain skeptical of its utility, maintaining low confidence in such black box systems, with this problem being exacerbated by low generalization for out-of-distribution (OOD) data. To move towards effective clinical utilization, we propose a foundation model named EvidenceCap, which makes the box transparent in a quantifiable way by uncertainty estimation. EvidenceCap not only makes AI visible in regions of uncertainty and OOD data, but also enhances the reliability, robustness, and computational efficiency of MIS. Uncertainty is modeled explicitly through subjective logic theory to gather strong evidence from features. We show the effectiveness of EvidenceCap in three segmentation datasets and apply it to the clinic. Our work sheds light on clinical safe applications and explainable AI, and can contribute towards trustworthiness in the medical domain.

Depression is a leading cause of death worldwide, and the diagnosis of depression is nontrivial. Multimodal learning is a popular solution for automatic diagnosis of depression, and the existing works suffer two main drawbacks: 1) the high-order interactions between different modalities can not be well exploited; and 2) interpretability of the models are weak. To remedy these drawbacks, we propose a multimodal multi-order factor fusion (MMFF) method. Our method can well exploit the high-order interactions between different modalities by extracting and assembling modality factors under the guide of a shared latent proxy. We conduct extensive experiments on two recent and popular datasets, E-DAIC-WOZ and CMDC, and the results show that our method achieve significantly better performance compared with other existing approaches. Besides, by analyzing the process of factor assembly, our model can intuitively show the contribution of each factor. This helps us understand the fusion mechanism.
