Multi-view representation learning has developed rapidly over the past decades and has been applied in many fields. However, most previous works assumed that each view is complete and aligned. This leads to an inevitable deterioration in their performance when encountering practical problems such as missing or unaligned views. To address the challenge of representation learning on partially aligned multi-view data, we propose a new cross-view graph contrastive learning framework, which integrates multi-view information to align data and learn latent representations. Compared with current approaches, the proposed method has the following merits: (1) our model is an end-to-end framework that simultaneously performs view-specific representation learning via view-specific autoencoders and cluster-level data aligning by combining multi-view information with the cross-view graph contrastive learning; (2) it is easy to apply our model to explore information from three or more modalities/sources as the cross-view graph contrastive learning is devised. Extensive experiments conducted on several real datasets demonstrate the effectiveness of the proposed method on the clustering and classification tasks.

我们报告了以前未被发现的多项式加强学习（MARL），名为“责任扩散”（DR）。博士导致谈判可靠的责任划分以完成复杂的合作任务。它反映了现有算法如何处理基于价值和基于策略的MARL方法的多种探索难题的缺陷。该DR问题与社会心理学领域（也称为旁观者效应）中具有相同名称的现象具有相似之处。在这项工作中，我们从理论上分析了DR问题的原因开始，我们强调DR问题与奖励成型或信用分配问题无关。为了解决DR问题，我们提出了一种政策共振方法，以改变多种勘探探索策略并促进MARL算法在困难的MARL任务中的性能。大多数现有的MARL算法可以配备此方法，以解决由DR问题引起的性能降解。实验是在多个测试基准任务中进行的，包括FME，诊断性多种环境和竞争性的多基因游戏ADCA。最后，我们在SOTA MARL算法上实施了策略共振方法，以说明这种方法的有效性。

多基础强化学习（MARL）可以解决复杂的合作任务。但是，现有的MAL方法的效率在很大程度上取决于明确定义的奖励功能。具有稀疏奖励反馈的多项式任务尤其具有挑战性，这不仅是由于信用分配问题，而且还因为获得积极的奖励反馈的可能性较低。在本文中，我们设计了一个称为合作图（CG）的图形网络。合作图是两个简单的二分图的组合，即代理聚类子图（ACG）和指定子图（CDG）的群集。接下来，基于这种新颖的图形结构，我们提出了一个合作图多力增强学习（CG-MARL）算法，该算法可以有效地处理多基因任务中的稀疏奖励问题。在CG-MARL中，代理由合作图直接控制。政策神经网络经过培训，可以操纵这一合作图，并指导代理人以隐式的方式实现合作。 CG-MARL的层次结构特征为定制集群活动提供了空间，这是一个可扩展的界面，用于引入基本合作知识。在实验中，CG-MARL在稀疏奖励多基准基准中显示出最新的性能，包括抗侵袭拦截任务和多货车交付任务。

行动预测旨在通过部分观察视频推断即将举行的人类行动，这是由于早期观察结果有限的信息有限。现有方法主要采用重建策略来处理此任务，期望从部分观察到完整视频来学习单个映射函数，以便于预测过程。在这项研究中，我们提出了来自两个新方面的部分视频查询生成“完整视频”功能调节的对抗性记忆网络（AMEMNet）。首先，键值结构化存储器发生器旨在将不同的部分视频存储为键存储器，并在具有门控机制和查询关注的值存储器中动态地写入完整视频。其次，我们开发了一个类感知判别者，以指导内存发生器在对抗训练时不仅提供现实，而且还提供鉴别的完整视频特征。通过RGB和光学流量的晚期融合给出了AMEMNET的最终预测结果。提供两个基准视频数据集，UCF-101和HMDB51的广泛实验结果，以证明所提出的AMEMNET模型在最先进的方法的有效性。

在本文中，我们考虑了在不完整视图上的多视图聚类问题。与完整的多视图聚类相比，视图缺失的问题会增加学习不同视图的常见表示的难度。为了解决挑战，我们提出了一种新颖的不完整的多视图聚类框架，该框架包含跨视网围传输和多视图融合学习。具体地，基于在多视图数据中存在的一致性，我们设计了一种基于跨视网围的转移转移的完成模块，该完成模块将已知与缺失视图的已知相似的相互关系的关系传输，并根据传输的图形网络恢复丢失的数据关系图。然后，设计特定于特定的编码器以提取恢复的多视图数据，引入基于注意的融合层以获得公共表示。此外，为了减少由视图之间不一致并获得更好的聚类结构引起的误差的影响，引入了联合聚类层以同时优化恢复和聚类。在几个真实数据集上进行的广泛实验证明了该方法的有效性。

在基因组生物学研究中，调节基因组建模是许多监管下游任务的重要课题，例如推动者分类，交易因子结合位点预测。核心问题是模拟监管元素如何相互交互及其跨不同小区类型的可变性。然而，目前的深度学习方法通​​常专注于建模固定的细胞类型集的基因组序列，并且不考虑多个调节元件之间的相互作用，使它们仅在训练集中的小区类型上表现良好，并且缺乏所需的概括生物学应用。在这项工作中，我们提出了一种简单但有效的方法，用于以多模态和自我监督的方式预先培训基因组数据，我们称之为Genebert。具体而言，我们同时服用1D基因组数据和2D矩阵（转录因子X区）作为输入，其中提出了三项预训练任务，以提高模型的鲁棒性和概括性。我们在ATAC-SEQ数据集上预先培训我们的模型，具有1700万基因组序列。我们在不同细胞类型中评估我们的Genebert关于监管下游任务，包括启动子分类，交易因子结合位点预测，疾病风险估计和剪接部位预测。广泛的实验证明了大型监管基因组学数据的多模态和自我监督的预培训的有效性。

基于图形的多视图聚类，旨在跨多种视图获取数据分区，近年来接受了相当大的关注。虽然已经为基于图形的多视图群集进行了巨大努力，但它对各种视图融合特征仍然是一个挑战，以学习聚类的常见表示。在本文中，我们提出了一种新的一致多曲线图嵌入聚类框架（CMGEC）。具体地，设计了一种多图自动编码器（M-GAE），用于使用多图注意融合编码器灵活地编码多视图数据的互补信息。为了引导所学过的公共表示维护每个视图中相邻特征的相似性，引入了多视图相互信息最大化模块（MMIM）。此外，设计了一个图形融合网络（GFN），以探讨来自不同视图的图表之间的关系，并提供M-GAE所需的常见共识图。通过联合训练这些模型，可以获得共同的潜在表示，其从多个视图中编码更多互补信息，并更全面地描绘数据。三种类型的多视图数据集的实验表明CMGEC优于最先进的聚类方法。

Despite significant progress in object categorization, in recent years, a number of important challenges remain; mainly, the ability to learn from limited labeled data and to recognize object classes within large, potentially open, set of labels. Zero-shot learning is one way of addressing these challenges, but it has only been shown to work with limited sized class vocabularies and typically requires separation between supervised and unsupervised classes, allowing former to inform the latter but not vice versa. We propose the notion of vocabulary-informed learning to alleviate the above mentioned challenges and address problems of supervised, zero-shot, generalized zero-shot and open set recognition using a unified framework. Specifically, we propose a weighted maximum margin framework for semantic manifold-based recognition that incorporates distance constraints from (both supervised and unsupervised) vocabulary atoms. Distance constraints ensure that labeled samples are projected closer to their correct prototypes, in the embedding space, than to others. We illustrate that resulting model shows improvements in supervised, zero-shot, generalized zero-shot, and large open set recognition, with up to 310K class vocabulary on Animal with Attributes and ImageNet datasets.

A noisy training set usually leads to the degradation of the generalization and robustness of neural networks. In this paper, we propose a novel theoretically guaranteed clean sample selection framework for learning with noisy labels. Specifically, we first present a Scalable Penalized Regression (SPR) method, to model the linear relation between network features and one-hot labels. In SPR, the clean data are identified by the zero mean-shift parameters solved in the regression model. We theoretically show that SPR can recover clean data under some conditions. Under general scenarios, the conditions may be no longer satisfied; and some noisy data are falsely selected as clean data. To solve this problem, we propose a data-adaptive method for Scalable Penalized Regression with Knockoff filters (Knockoffs-SPR), which is provable to control the False-Selection-Rate (FSR) in the selected clean data. To improve the efficiency, we further present a split algorithm that divides the whole training set into small pieces that can be solved in parallel to make the framework scalable to large datasets. While Knockoffs-SPR can be regarded as a sample selection module for a standard supervised training pipeline, we further combine it with a semi-supervised algorithm to exploit the support of noisy data as unlabeled data. Experimental results on several benchmark datasets and real-world noisy datasets show the effectiveness of our framework and validate the theoretical results of Knockoffs-SPR. Our code and pre-trained models will be released.

As natural language processing (NLP) for gender bias becomes a significant interdisciplinary topic, the prevalent data-driven techniques such as large-scale language models suffer from data inadequacy and biased corpus, especially for languages with insufficient resources such as Chinese. To this end, we propose a Chinese cOrpus foR Gender bIas Probing and Mitigation CORGI-PM, which contains 32.9k sentences with high-quality labels derived by following an annotation scheme specifically developed for gender bias in the Chinese context. Moreover, we address three challenges for automatic textual gender bias mitigation, which requires the models to detect, classify, and mitigate textual gender bias. We also conduct experiments with state-of-the-art language models to provide baselines. To our best knowledge, CORGI-PM is the first sentence-level Chinese corpus for gender bias probing and mitigation.
