营销活动是一系列战略活动,可以促进企业的目标。在真正的工业场景中,营销活动的效果预测非常复杂且具有挑战性,因为通常从观察数据中学到了先验知识,而没有任何营销活动干预。此外,每个主题始终在几个营销活动的干预下同时受到干扰。因此,我们无法轻松解析和评估单个营销活动的效果。据我们所知,目前尚无有效的方法来解决此类问题,即,基于具有多个相互缠绕事件的层次结构对个体级别的预测任务进行建模。在本文中,我们对效果预测任务中涉及的基础解析树的结构进行了深入的分析,并进一步建立了一个层次结构胶囊预测网络(HAPNET)来预测营销活动的影响。基于合成数据和实际数据的广泛结果证明了我们模型比最新方法的优越性,并在实际工业应用中表现出显着的实用性。

深度神经网络的兴起为优化推荐系统提供了重要的驱动力。但是,推荐系统的成功在于精致的建筑制造,因此呼吁神经建筑搜索(NAS)进一步改善其建模。我们提出了NASREC,它是一种训练单个超级网的范式,并通过重量共享有效地产生丰富的模型/子构造。为了克服数据多模式和体系结构异质性挑战,NASREC建立了一个大型的超级网(即搜索空间),以搜索完整的体系结构,而SuperNet结合了多功能操作员的选择和密集的连接性选择,并使人类的密集连接性最小化。 Nasrec的规模和异质性在搜索中构成了挑战,例如训练效率低下,操作员不平衡和降级等级相关性。我们通过提出单操作员任何连接采样,操作员平衡互动模块和训练后微调来应对这些挑战。我们对三个点击率(CTR)预测基准测试的结果表明,NASREC可以胜过手动设计的模型和现有的NAS方法,从而实现最先进的性能。

引用视频对象细分任务(RVO)的目的是在所有视频框架中通过语言表达式引用的给定视频中的对象实例。由于需要在各个实例中理解跨模式语义,因此此任务比传统的半监督视频对象细分更具挑战性,在该视频对象分割中,在第一帧中给出了地面真相对象掩盖。随着变压器在对象检测和对象细分方面的巨大成就,RVOS已取得了显着的进步,而Reformen to Reformer实现了最新的性能。在这项工作中,基于强大的基线框架 - 引用者,我们提出了几个技巧来进一步提高,包括周期性学习率,半监督方法和测试时间增加推断。改进的推荐子在CVPR2022上排名第二,参考YouTube-VOS挑战。

风险的准确器官(OAR)分割对于减少治疗后并发症的放射治疗至关重要。达人指南推荐头部和颈部(H&N)区域的一套超过40桨的桨,然而,由于这项任务的可预测的禁止劳动力成本,大多数机构通过划定较小的桨子和忽视的少数,选择了大量简化的协议与其他桨相关的剂量分布。在这项工作中,我们提出了一种使用深度学习的新颖,自动化和高效的分层OAR分段(SOARS)系统,精确地描绘了一套全面的42 H&N OAR。 SOARS将42桨分层进入锚,中级和小型和硬质子类别,通过神经结构搜索(NAS)原则,专门为每个类别提供神经网络架构。我们在内在机构中使用176名培训患者建立了SOAR模型,并在六个不同的机构中独立评估了1327名外部患者。对于每个机构评估,它始终如一地表现出其他最先进的方法至少3-5%的骰子得分(在其他度量的相对误差减少36%)。更重要的是,广泛的多用户研究明显证明,98%的SOARE预测只需要非常轻微或没有直接临床验收的修订(节省90%的辐射脑神经工作负载),并且它们的分割和剂量准确度在于或小于帧 - 用户的变化。这些调查结果证实了H&N癌症放射疗法工作流OAR描绘过程的强烈临床适用性,提高了效率,全面性和质量。

已经研究了几十年的上下文多武装匪,并适应了各种应用,如在线广告和个性化推荐。为了解决匪徒的开发探索权衡,有三种主要技术:epsilon - 贪婪,汤普森采样(TS)和上置信度(UCB)。在最近的文献中,线性上下窗匪徒采用了脊回归来估计奖励功能,并将其与TS或UCB策略结合起来的探索。但是,这行作品明确假设奖励基于ARM向量的线性函数,在现实世界数据集中可能不是真的。为了克服这一挑战,已经提出了一系列神经基的强盗算法,其中分配了神经网络以学习基础奖励功能,并且TS或UCB适于探索。在本文中,我们提出了一种具有新的探索策略的神经基匪徒方法。除了利用神经网络(开发网络)外学习奖励功能之外,与目前估计的奖励相比,EE-Net采用另一个神经网络(勘探网络)来自适应地学习潜在的增益。然后,构建决策者以将输出与剥削和探索网络组合起来。我们证明了EE-Net实现了$ \ mathcal {o}(\ sqrt {t \ log t})$后悔,它比现有最先进的神经强盗算法更紧密($ \ mathcal {o}(\基于UCB和TS的SQRT {T} \ log t)$。通过对四世界数据集的广泛实验,我们表明EE-Net优于现有的线性和神经匪徒的方法。

在视觉上丰富的文件(VRD)上的结构化文本理解是文档智能的重要组成部分。由于VRD中的内容和布局的复杂性,结构化文本理解是一项有挑战性的任务。大多数现有的研究将此问题与两个子任务结尾:实体标记和实体链接,这需要整体地了解令牌和段级别的文档的上下文。但是,很少的工作已经关注有效地从不同层次提取结构化数据的解决方案。本文提出了一个名为structext的统一框架,它对于处理两个子任务是灵活的,有效的。具体地,基于变压器,我们引入了一个段令牌对齐的编码器,以处理不同粒度水平的实体标记和实体链接任务。此外,我们设计了一种具有三个自我监督任务的新型预训练策略,以学习更丰富的代表性。 Structext使用现有屏蔽的视觉语言建模任务和新句子长度预测和配对框方向任务,以跨文本,图像和布局结合多模态信息。我们评估我们在分段级别和令牌级别的结构化文本理解的方法,并表明它优于最先进的同行,在Funsd,Srie和Ephoie数据集中具有显着优越的性能。

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.

The development of social media user stance detection and bot detection methods rely heavily on large-scale and high-quality benchmarks. However, in addition to low annotation quality, existing benchmarks generally have incomplete user relationships, suppressing graph-based account detection research. To address these issues, we propose a Multi-Relational Graph-Based Twitter Account Detection Benchmark (MGTAB), the first standardized graph-based benchmark for account detection. To our knowledge, MGTAB was built based on the largest original data in the field, with over 1.55 million users and 130 million tweets. MGTAB contains 10,199 expert-annotated users and 7 types of relationships, ensuring high-quality annotation and diversified relations. In MGTAB, we extracted the 20 user property features with the greatest information gain and user tweet features as the user features. In addition, we performed a thorough evaluation of MGTAB and other public datasets. Our experiments found that graph-based approaches are generally more effective than feature-based approaches and perform better when introducing multiple relations. By analyzing experiment results, we identify effective approaches for account detection and provide potential future research directions in this field. Our benchmark and standardized evaluation procedures are freely available at: https://github.com/GraphDetec/MGTAB.

Learning feature interactions is the key to success for the large-scale CTR prediction and recommendation. In practice, handcrafted feature engineering usually requires exhaustive searching. In order to reduce the high cost of human efforts in feature engineering, researchers propose several deep neural networks (DNN)-based approaches to learn the feature interactions in an end-to-end fashion. However, existing methods either do not learn both vector-wise interactions and bit-wise interactions simultaneously, or fail to combine them in a controllable manner. In this paper, we propose a new model, xDeepInt, based on a novel network architecture called polynomial interaction network (PIN) which learns higher-order vector-wise interactions recursively. By integrating subspace-crossing mechanism, we enable xDeepInt to balance the mixture of vector-wise and bit-wise feature interactions at a bounded order. Based on the network architecture, we customize a combined optimization strategy to conduct feature selection and interaction selection. We implement the proposed model and evaluate the model performance on three real-world datasets. Our experiment results demonstrate the efficacy and effectiveness of xDeepInt over state-of-the-art models. We open-source the TensorFlow implementation of xDeepInt: https://github.com/yanyachen/xDeepInt.

In this paper, we study the problem of knowledge-intensive text-to-SQL, in which domain knowledge is necessary to parse expert questions into SQL queries over domain-specific tables. We formalize this scenario by building a new Chinese benchmark KnowSQL consisting of domain-specific questions covering various domains. We then address this problem by presenting formulaic knowledge, rather than by annotating additional data examples. More concretely, we construct a formulaic knowledge bank as a domain knowledge base and propose a framework (ReGrouP) to leverage this formulaic knowledge during parsing. Experiments using ReGrouP demonstrate a significant 28.2% improvement overall on KnowSQL.
