Large-scale pre-trained language models (PLMs) bring new opportunities to challenge problems, especially those that need high-level intelligence, such as the math word problem (MWPs). However, directly applying existing PLMs to MWPs can fail as the generation process lacks sufficient supervision and thus lacks fast adaptivity as humans. We notice that human reasoning has a dual reasoning framework that consists of an immediate reaction system (system 1) and a delicate reasoning system (system 2), where the entire reasoning is determined by their interaction. This inspires us to develop a cooperative reasoning-induced PLM for solving MWPs, called Cooperative Reasoning (CoRe), resulting in a human-like reasoning architecture with system 1 as the generator and system 2 as the verifier. In our approach, the generator is responsible for generating reasoning paths, and the verifiers are used to supervise the evaluation in order to obtain reliable feedback for the generator. We evaluate our CoRe framework on several mathematical reasoning datasets and achieve decent improvement over state-of-the-art methods, up to 9.8% increase over best baselines.

如今，基础模型已成为人工智能中的基本基础设施之一，铺平了通往通用情报的方式。但是，现实提出了两个紧急挑战：现有的基础模型由英语社区主导；用户通常会获得有限的资源，因此不能总是使用基础模型。为了支持中文社区的发展，我们介绍了一个名为Fengshenbang的开源项目，该项目由认知计算与自然语言研究中心（CCNL）领导。我们的项目具有全面的功能，包括大型预培训模型，用户友好的API，基准，数据集等。我们将所有这些都包装在三个子项目中：风水次模型，风水框架和狂热基准。 Fengshenbang的开源路线图旨在重新评估中国预培训的大型大型模型的开源社区，促使整个中国大型模型社区的发展。我们还希望构建一个以用户为中心的开源生态系统，以允许个人访问所需的模型以匹配其计算资源。此外，我们邀请公司，大学和研究机构与我们合作建立大型开源模型的生态系统。我们希望这个项目将成为中国认知情报的基础。

人类可以不断学习新知识。但是，在学习新任务后，机器学习模型在以前的任务上的性能急剧下降。认知科学指出，类似知识的竞争是遗忘的重要原因。在本文中，我们根据大脑的元学习和关联机制设计了一个用于终身学习的范式。它从两个方面解决了问题：提取知识和记忆知识。首先，我们通过背景攻击破坏样本的背景分布，从而增强了模型以提取每个任务的关键特征。其次，根据增量知识和基础知识之间的相似性，我们设计了增量知识的自适应融合，这有助于模型将能力分配到不同困难的知识。理论上分析了所提出的学习范式可以使不同任务的模型收敛到相同的最优值。提出的方法已在MNIST，CIFAR100，CUB200和ImagEnet100数据集上进行了验证。

乐器识别是广泛应用的音乐信息检索应用。由于以前的大多数乐器识别数据集专注于西方乐器，研究人员很难研究和评估传统的中国乐器识别领域。本文提出了传统的中国音乐数据集，用于培训模型和绩效评估，名为Chmusic。此数据集是免费且公开的，11名中国传统音乐仪器和55名繁体中文音乐摘录在此数据集中录制。然后基于Chmusic数据集提出了评估标准。通过本标准，研究人员可以按照相同规则进行比较它们的结果，不同的研究人员的结果将变得可比。

Dose verification based on proton-induced positron emitters is a promising quality assurance tool and may leverage the strength of artificial intelligence. To move a step closer towards practical application, the sensitivity analysis of two factors needs to be performed: biological washout and depth selection. selection. A bi-directional recurrent neural network (RNN) model was developed. The training dataset was generated based upon a CT image-based phantom (abdomen region) and multiple beam energies/pathways, using Monte-Carlo simulation (1 mm spatial resolution, no biological washout). For the modeling of biological washout, a simplified analytical model was applied to change raw activity profiles over a period of 5 minutes, incorporating both physical decay and biological washout. For the study of depth selection (a challenge linked to multi field/angle irradiation), truncations were applied at different window lengths (100, 125, 150 mm) to raw activity profiles. Finally, the performance of a worst-case scenario was examined by combining both factors (depth selection: 125 mm, biological washout: 5 mins). The accuracy was quantitatively evaluated in terms of range uncertainty, mean absolute error (MAE) and mean relative errors (MRE). Our proposed AI framework shows good immunity to the perturbation associated with two factors. The detection of proton-induced positron emitters, combined with machine learning, has great potential to implement online patient-specific verification in proton therapy.

Objects in a scene are not always related. The execution efficiency of the one-stage scene graph generation approaches are quite high, which infer the effective relation between entity pairs using sparse proposal sets and a few queries. However, they only focus on the relation between subject and object in triplet set subject entity, predicate entity, object entity, ignoring the relation between subject and predicate or predicate and object, and the model lacks self-reasoning ability. In addition, linguistic modality has been neglected in the one-stage method. It is necessary to mine linguistic modality knowledge to improve model reasoning ability. To address the above-mentioned shortcomings, a Self-reasoning Transformer with Visual-linguistic Knowledge (SrTR) is proposed to add flexible self-reasoning ability to the model. An encoder-decoder architecture is adopted in SrTR, and a self-reasoning decoder is developed to complete three inferences of the triplet set, s+o-p, s+p-o and p+o-s. Inspired by the large-scale pre-training image-text foundation models, visual-linguistic prior knowledge is introduced and a visual-linguistic alignment strategy is designed to project visual representations into semantic spaces with prior knowledge to aid relational reasoning. Experiments on the Visual Genome dataset demonstrate the superiority and fast inference ability of the proposed method.

Change detection (CD) is to decouple object changes (i.e., object missing or appearing) from background changes (i.e., environment variations) like light and season variations in two images captured in the same scene over a long time span, presenting critical applications in disaster management, urban development, etc. In particular, the endless patterns of background changes require detectors to have a high generalization against unseen environment variations, making this task significantly challenging. Recent deep learning-based methods develop novel network architectures or optimization strategies with paired-training examples, which do not handle the generalization issue explicitly and require huge manual pixel-level annotation efforts. In this work, for the first attempt in the CD community, we study the generalization issue of CD from the perspective of data augmentation and develop a novel weakly supervised training algorithm that only needs image-level labels. Different from general augmentation techniques for classification, we propose the background-mixed augmentation that is specifically designed for change detection by augmenting examples under the guidance of a set of background-changing images and letting deep CD models see diverse environment variations. Moreover, we propose the augmented & real data consistency loss that encourages the generalization increase significantly. Our method as a general framework can enhance a wide range of existing deep learning-based detectors. We conduct extensive experiments in two public datasets and enhance four state-of-the-art methods, demonstrating the advantages of our method. We release the code at https://github.com/tsingqguo/bgmix.

道路网络的图结构对于自动驾驶系统的下游任务，例如全球计划，运动预测和控制至关重要。过去，公路网络图通常由人类专家手动注释，这是耗时且劳动力密集的。为了获得更好的有效性和效率的道路网络图，需要进行自动的路网图检测方法。先前的作品要么是后处理的语义分割图，要么提出基于图的算法以直接预测道路网络图。但是，以前的作品遭受了硬编码的启发式处理算法和劣质最终性能。为了增强先前的SOTA（最新方法）方法RNGDET，我们添加了一个实例分割头，以更好地监督模型培训，并使模型能够利用骨干网络的多尺度功能。由于新提出的方法从RNGDET改进，因此命名为RNGDET ++。所有方法均在大型公开数据集上进行评估。 RNGDET ++在几乎所有度量分数上都优于基线模型。它将拓扑正确性APL（平均路径长度相似性）提高了3 \％。演示视频和补充材料可在我们的项目页面\ url {https://tonyxuqaq.github.io/projects/rngdetplusplus/}中获得。

随着自动驾驶汽车的快速发展，目击者对高清地图（HD地图）的需求蓬勃发展，这些地图（HD地图）在自主驾驶场景中提供了可靠且强大的静态环境信息。作为高清图中的主要高级元素之一，道路车道中心线对于下游任务（例如预测和计划）至关重要。人类注释器手动注释车道中心线高清图是劳动密集型，昂贵且效率低下的，严重限制了自动驾驶系统的广泛应用和快速部署。以前的工作很少探索中心线高清图映射问题，这是由于拓扑复杂和道路中心线的严重重叠问题。在本文中，我们提出了一种名为CenterLinedet的新方法，以自动创建Lane Centrine HD地图。通过模仿学习对CenterLinedet进行训练，并可以通过使用车辆安装的传感器进行迭代有效地检测到车道中心线的图。由于应用了类似DITR的变压器网络，CenterLinedet可以处理复杂的图形拓扑，例如车道相交。在大型公开数据集Nuscenes上评估了所提出的方法，并通过比较结果很好地证明了CenterLinedet的优势。本文附有一个演示视频和一个补充文档，可在\ url {https://tonyxuqaq.github.io/projects/centerlinedet/}中获得。

物流运营商最近提出了一项技术，可以帮助降低城市货运分销中的交通拥堵和运营成本，最近提出了移动包裹储物柜（MPLS）。鉴于他们能够在整个部署领域搬迁，因此他们具有提高客户可访问性和便利性的潜力。在这项研究中，我们制定了移动包裹储物柜问题（MPLP），这是位置路由问题（LRP）的特殊情况，该案例确定了整天MPL的最佳中途停留位置以及计划相应的交付路线。开发了基于混合Q学习网络的方法（HQM），以解决所得大问题实例的计算复杂性，同时逃脱了本地Optima。此外，HQM与全球和局部搜索机制集成在一起，以解决经典强化学习（RL）方法所面临的探索和剥削困境。我们检查了HQM在不同问题大小（最多200个节点）下的性能，并根据遗传算法（GA）进行了基准测试。我们的结果表明，HQM获得的平均奖励比GA高1.96倍，这表明HQM具有更好的优化能力。最后，我们确定有助于车队规模要求，旅行距离和服务延迟的关键因素。我们的发现概述了MPL的效率主要取决于时间窗口的长度和MPL中断的部署。
