Previous computation models either have equivalent abilities in representing all computations but fail to provide primitive operators for programming complex algorithms or lack generalized expression ability to represent newly-added computations. This article presents a unified computation model with generalized expression ability and a concise set of primitive operators for programming high-level algorithms. We propose a unified data abstraction -- Tensor of List, and offer a unified computation model based on Tensor of List, which we call the ToL model (in short, ToL). ToL introduces five atomic computations that can represent any elementary computation by finite composition, ensured with strict formal proof. Based on ToL, we design a pure-functional language -- ToLang. ToLang provides a concise set of primitive operators that can be used to program complex big data and AI algorithms. Our evaluations show ToL has generalized expression ability and a built-in performance indicator, born with a strictly defined computation metric -- elementary operation count (EOPs), consistent with FLOPs within a small error range.

Negotiation is one of the crucial abilities in human communication, and there has been a resurgent research interest in negotiation dialogue systems recently, which goal is to empower intelligent agents with such ability that can efficiently help humans resolve conflicts or reach beneficial agreements. Although there have been many explorations in negotiation dialogue systems, a systematic review of this task has to date remained notably absent. To this end, we aim to fill this gap by reviewing contemporary studies in the emerging field of negotiation dialogue systems, covering benchmarks, evaluations, and methodologies. Furthermore, we also discuss potential future directions, including multi-modal, multi-party, and cross-cultural negotiation scenarios. Our goal is to provide the community with a systematic overview of negotiation dialogue systems and to inspire future research.

Conventional cameras capture image irradiance on a sensor and convert it to RGB images using an image signal processor (ISP). The images can then be used for photography or visual computing tasks in a variety of applications, such as public safety surveillance and autonomous driving. One can argue that since RAW images contain all the captured information, the conversion of RAW to RGB using an ISP is not necessary for visual computing. In this paper, we propose a novel $\rho$-Vision framework to perform high-level semantic understanding and low-level compression using RAW images without the ISP subsystem used for decades. Considering the scarcity of available RAW image datasets, we first develop an unpaired CycleR2R network based on unsupervised CycleGAN to train modular unrolled ISP and inverse ISP (invISP) models using unpaired RAW and RGB images. We can then flexibly generate simulated RAW images (simRAW) using any existing RGB image dataset and finetune different models originally trained for the RGB domain to process real-world camera RAW images. We demonstrate object detection and image compression capabilities in RAW-domain using RAW-domain YOLOv3 and RAW image compressor (RIC) on snapshots from various cameras. Quantitative results reveal that RAW-domain task inference provides better detection accuracy and compression compared to RGB-domain processing. Furthermore, the proposed \r{ho}-Vision generalizes across various camera sensors and different task-specific models. Additional advantages of the proposed $\rho$-Vision that eliminates the ISP are the potential reductions in computations and processing times.

For the aerial manipulator that performs aerial work tasks, the actual operating environment it faces is very complex, and it is affected by internal and external multi-source disturbances. In this paper, to effectively improve the anti-disturbance control performance of the aerial manipulator, an adaptive neural network backstepping control method based on variable inertia parameter modeling is proposed. Firstly, for the intense internal coupling disturbance, we analyze and model it from the perspective of the generation mechanism of the coupling disturbance, and derive the dynamics model of the aerial manipulator system and the coupling disturbance model based on the variable inertia parameters. Through the proposed coupling disturbance model, we can compensate the strong coupling disturbance in a way of feedforward. Then, the adaptive neural network is proposed and applid to estimate and compensate the additional disturbances, and the closed-loop controller is designed based on the backstepping control method. Finally, we verify the correctness of the proposed coupling disturbance model through physical experiment under a large range motion of the manipulator. Two sets of comparative simulation results also prove the accurate estimation of the proposed adaptive neural network for additional disturbances and the effectiveness and superiority of the proposed control method.

In this work, we present a new computer vision task named video object of interest segmentation (VOIS). Given a video and a target image of interest, our objective is to simultaneously segment and track all objects in the video that are relevant to the target image. This problem combines the traditional video object segmentation task with an additional image indicating the content that users are concerned with. Since no existing dataset is perfectly suitable for this new task, we specifically construct a large-scale dataset called LiveVideos, which contains 2418 pairs of target images and live videos with instance-level annotations. In addition, we propose a transformer-based method for this task. We revisit Swin Transformer and design a dual-path structure to fuse video and image features. Then, a transformer decoder is employed to generate object proposals for segmentation and tracking from the fused features. Extensive experiments on LiveVideos dataset show the superiority of our proposed method.

This technical report briefly describes our JDExplore d-team's Vega v2 submission on the SuperGLUE leaderboard. SuperGLUE is more challenging than the widely used general language understanding evaluation (GLUE) benchmark, containing eight difficult language understanding tasks, including question answering, natural language inference, word sense disambiguation, coreference resolution, and reasoning. [Method] Instead of arbitrarily increasing the size of a pretrained language model (PLM), our aim is to 1) fully extract knowledge from the input pretraining data given a certain parameter budget, e.g., 6B, and 2) effectively transfer this knowledge to downstream tasks. To achieve goal 1), we propose self-evolution learning for PLMs to wisely predict the informative tokens that should be masked, and supervise the masked language modeling (MLM) process with rectified smooth labels. For goal 2), we leverage the prompt transfer technique to improve the low-resource tasks by transferring the knowledge from the foundation model and related downstream tasks to the target task. [Results] According to our submission record (Oct. 2022), with our optimized pretraining and fine-tuning strategies, our 6B Vega method achieved new state-of-the-art performance on 4/8 tasks, sitting atop the SuperGLUE leaderboard on Oct. 8, 2022, with an average score of 91.3.

与大脑变化相关的阿尔茨海默氏病（AD）和轻度认知障碍（MCI）的评估仍然是一项艰巨的任务。最近的研究表明，多模式成像技术的组合可以更好地反映病理特征，并有助于更准确地诊断AD和MCI。在本文中，我们提出了一种新型的基于张量的多模式特征选择和回归方法，用于诊断和生物标志物对正常对照组的AD和MCI鉴定。具体而言，我们利用张量结构来利用多模式数据中固有的高级相关信息，并研究多线性回归模型中的张量级稀疏性。我们使用三种成像方式（VBM- MRI，FDG-PET和AV45-PET）具有疾病严重程度和认知评分的临床参数来分析ADNI数据的方法的实际优势。实验结果表明，我们提出的方法与疾病诊断的最新方法的优越性能以及疾病特异性区域和与模态相关的差异的鉴定。这项工作的代码可在https://github.com/junfish/bios22上公开获得。

言语的数字，例如隐喻和讽刺，在文学作品和口语对话中无处不在。这对自然语言理解构成了巨大的挑战，因为语音的数字通常偏离表面上表达更深层次的语义含义的含义。先前的研究强调了数字的文学方面，很少从计算语言学的观点提供全面的探索。在本文中，我们首先提出了象征性单元的概念，该单元是人物的载体。然后，我们选择了中文常用的12种类型的数字，并构建中文语料库以进行上下文化的图形识别（配置）。与以前的令牌级别或句子级别对应物不同，配置旨在从话语级别的上下文中提取象征性单元，并将象征性单元分类为正确的图类型。在配置时，设计了三个任务，即图形提取，图类型分类和图形识别，并使用最新技术来实现基准。我们进行彻底的实验，并表明所有三个任务对于现有模型都充满挑战，因此需要进一步研究。我们的数据集和代码可在https://github.com/pku-tangent/configure上公开获取。

当许多松散相关的未标记数据可用并且稀缺标记的数据时，机器智能的范式从纯粹的监督学习转变为更实用的情况。大多数现有算法都假定基础任务分布是固定的。在这里，我们考虑了随着时间的推移，该任务分布中的一个更现实和具有挑战性的环境会不断发展。我们将这个问题称为半监督的元学习，并具有不断发展的任务分布，缩写为集合。在这种更现实的环境中出现了两个关键挑战：（i）在存在大量未标记的分发（OOD）数据的情况下，如何使用未标记的数据； （ii）如何防止由于任务分配转移而导致先前学习的任务分布的灾难性遗忘。我们提出了一种强大的知识和知识保留的半监督元学习方法（秩序），以应对这两个主要挑战。具体而言，我们的订单引入了一种新型的共同信息正则化，以使用未标记的OOD数据鲁棒化模型，并采用最佳的运输正规化来记住以前在特征空间中学习的知识。此外，我们在一个非常具有挑战性的数据集上测试我们的方法：大规模非平稳的半监督任务分布的集合，该任务分布由（至少）72K任务组成。通过广泛的实验，我们证明了拟议的订单减轻了忘记不断发展的任务分布，并且对OOD数据比相关的强基础更强大。

模拟在有效评估自动驾驶汽车方面发挥了重要作用。现有方法主要依赖于基于启发式的模拟，在该模拟中，交通参与者遵循某些无法产生复杂人类行为的人类编码的规则。因此，提出了反应性仿真概念，以通过利用现实世界数据来弥合模拟和现实世界交通情况之间的人类行为差距。但是，这些反应性模型可以在模拟几个步骤后轻松地产生不合理的行为，我们将模型视为失去其稳定性。据我们所知，没有任何工作明确讨论并分析了反应性仿真框架的稳定性。在本文中，我们旨在对反应性模拟进行彻底的稳定性分析，并提出一种增强稳定性的解决方案。具体而言，我们首先提出了一个新的反应模拟框架，在其中我们发现模拟状态序列的平滑度和一致性是稳定性的关键因素。然后，我们将运动学媒介物模型纳入框架中，以提高反应性模拟的闭环稳定性。此外，在本文中提出了一些新颖的指标，以更好地分析模拟性能。
