Recent successes in applying deep learning to solve many challenging data science problems is in part due to the availability of large-scale labeled training data. However, creating large-scale labeled datasets is time consuming, labor-intensive, costly, and often requires significant domain knowledge. Many real-world applications, therefore, come with only data with limited label information (i.e., a small amount of labeled data or no labeled data). Thus, lack of labeled training data is still one of major roadblocks in applying deep learning techniques to challenging data science problems. On the other hand, recent advancements in generative adversarial learning have shown promising results in generating realistic data, which could enable a new perspective for alleviating the problem of lacking labeled training data. Thus, this project explores effective labeled data generation via generative adversarial learning. The proposed research extends the state-of-the-art labeled data generation and generative adversarial learning to a new frontier, investigates original problems that entreat innovative solutions and paves the way for a new research endeavor effectively tame synthetic labeled data generation. As many real-world problems face the challenge of limited labeled data, the project has potential to benefit many real-world applications from various disciplines such as Computer Science, Education, Politics, Healthcare and Bioinformatics.This project proposes novel approaches based on generative adversarial learning for effective labeled data generation to facilitate deep learning with limited label information, investigates associated fundamental research issues and develops effective algorithms. It has three primary research objectives. First, when a small amount of labeled data is available, it explores to estimate the underlying data distribution from unlabeled data and incorporate the label information for labeled data generation, including extremely imbalanced data and incomplete label scenarios. Second, when labeled data is not available, it adopts an alternative weak supervision (e.g., inaccurate labels, inexact labels and pairwise constraints) for generating labeled data. Third, when neither labeled data nor weak supervision is available, it explores to integrate human involvement to generative adversarial learning for providing supervision. Disparate means are planned to disseminate the project and its findings, such as web enabled data and software repositories, books, journal and conference publications, special purpose workshops or tutorials, and industrial collaborations. The project can be effectively integrated to undergraduate and graduate courses as well as in student research projects.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在应用深度学习来解决许多具有挑战性的数据科学问题方面，最近取得的成功部分是由于具有大规模标记的培训数据的可用性。但是，创建大规模标记的数据集是耗时，劳动力密集，昂贵的，并且通常需要重要的领域知识。因此，许多实际应用程序仅包含具有有限标签信息的数据（即少量标记的数据或没有标记的数据）。因此，缺乏标记的培训数据仍然是将深度学习技术应用于挑战性数据科学问题的主要障碍之一。另一方面，生成对抗性学习的最新进展在生成现实数据方面显示出令人鼓舞的结果，这可以使新的观点减轻缺乏标记的培训数据的问题。因此，该项目通过生成对抗性学习探索了有效的标记数据生成。拟议的研究将最先进的标记数据生成和生成对抗性学习扩展到了新的边境，研究了原始问题，这些问题吸引了创新的解决方案，并为一项新的研究努力铺平了道路，从而有效地驯服了合成标记的数据生成。 As many real-world problems face the challenge of limited labeled data, the project has potential to benefit many real-world applications from various disciplines such as Computer Science, Education, Politics, Healthcare and Bioinformatics.This project proposes novel approaches based on generative adversarial learning for effective labeled data generation to facilitate deep learning with limited label information, investigates associated fundamental research issues and develops effective algorithms.它具有三个主要的研究目标。首先，当有少量标记的数据可用时，它将探索以估算未标记数据的基础数据分布，并将标签信息包含在标签数据生成中，包括极度不平衡的数据和不完整的标签场景。其次，当没有标记的数据可用时，它会采用替代性弱监督（例如，标签不正确，不精确标签和成对约束）来生成标记的数据。第三，当没有标记的数据或弱监督下，它会探索以将人类参与到生成的对抗性学习中以提供监督。计划分散的手段来传播该项目及其发现，例如启用Web的数据和软件存储库，书籍，期刊和会议出版物，特殊目的研讨会或教程以及工业合作。该项目可以有效地整合到本科和研究生课程以及学生研究项目中。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来获得支持的。
