随着深度学习技术的发展,监督学习已经达到了超越人类的表现。研究人员为不同的数据模态设计了许多相应的模型,在监督任务中取得了优秀的结果。然而,随着多个领域数据的指数增长,未标记数据的识别和分类逐渐成为一个热门话题。本文采用了强化学习框架来模拟人类的认知过程,以有效地解决开放集领域中的新类别发现问题。我们采用了一种成员到领导者的多智能体框架来从多模态信息中提取和融合特征,旨在获得更全面的特征空间理解。此外,这种方法促进了自监督学习的整合,以增强模型训练。我们采用了一种聚类方法,具有不同的约束条件,从严格到宽松,允许在训练阶段为未标记数据的子集生成可靠的标签。这个迭代的过程类似于人类对未知数据的探索学习。这些机制根据从环境反馈中获得的奖励来更新网络参数。这个过程可以有效地控制探索学习的程度,确保在未知数据类别的学习准确性。我们通过采用OS-MN40、OS-MN40-Miss和Cifar10数据集,在3D和2D领域中展示了我们方法的性能。我们的方法取得了竞争性的结果。基于文本条件的人类动作生成技术越来越受欢迎,它允许用户通过自然语言进行交互。现有的方法通常根据单个输入句子生成短而孤立的动作。然而,人类的动作是连续的,可以持续很长时间,并且包含丰富的语义信息。创建能够精确响应文本描述流的长时间、复杂动作,特别是在在线和实时环境中,仍然是一个重大挑战。此外,将空间约束纳入基于文本条件的动作生成中带来了额外的挑战,因为它需要将文本描述所指定的动作语义与几何信息(如目标位置和3D场景几何)对齐。 为了解决这些局限性,我们提出了DartControl,简称DART,这是一种基于扩散模型的自回归动作基元模型,用于实时文本驱动的动作控制。我们的模型利用潜在扩散模型有效地学习了一个紧凑的动作基元空间,该空间同时依赖于动作历史和文本输入。通过根据先前的历史和当前文本输入自回归地生成动作基元,DART实现了由自然语言描述驱动的实时、顺序动作生成。 此外,所学的动作基元空间允许精确的空间动作控制,我们将其表述为潜在噪声优化问题或通过强化学习解决的马尔可夫决策过程。我们提出了两种方法的有效算法,展示了我们模型在各种动作合成任务中的多功能性和卓越性能。实验表明,我们的方法在动作的真实感、效率和可控性方面优于现有的基准方法。视频结果可以在项目页面上查看:https://zkf1997.github.io/DART/。
With the development of deep learning techniques, supervised learning has achieved performances surpassing those of humans. Researchers have designed numerous corresponding models for different data modalities, achieving excellent results in supervised tasks. However, with the exponential increase of data in multiple fields, the recognition and classification of unlabeled data have gradually become a hot topic. In this paper, we employed a Reinforcement Learning framework to simulate the cognitive processes of humans for effectively addressing novel class discovery in the Open-set domain. We deployed a Member-to-Leader Multi-Agent framework to extract and fuse features from multi-modal information, aiming to acquire a more comprehensive understanding of the feature space. Furthermore, this approach facilitated the incorporation of self-supervised learning to enhance model training. We employed a clustering method with varying constraint conditions, ranging from strict to loose, allowing for the generation of dependable labels for a subset of unlabeled data during the training phase. This iterative process is similar to human exploratory learning of unknown data. These mechanisms collectively update the network parameters based on rewards received from environmental feedback. This process enables effective control over the extent of exploration learning, ensuring the accuracy of learning in unknown data categories. We demonstrate the performance of our approach in both the 3D and 2D domains by employing the OS-MN40, OS-MN40-Miss, and Cifar10 datasets. Our approach achieves competitive competitive results.
