The growing field of data science promises to bring many benefits to society: personalized knowledge and services; improved healthcare; improved decision-making at individual, organizational, national, and international levels; a safer and possibly fairer society; and many others. The ability to realize these promises, however, depends critically on building the right foundational principles for the field. This project establishes an NSF TRIPODS Institute, termed the Penn Institute for Foundations of Data Science (PIFODS), at the University of Pennsylvania, with the goal of bringing together scientists and ideas from multiple disciplines, including computer science, electrical engineering, statistics, and mathematics, in order to collectively develop long-lasting principles for data science that can serve the field for decades to come. The main activities of the Institute will include transdisciplinary research, education and training, engagement with the broader research community through invited seminars and workshops, and engagement with applied scientists and practitioners. The PIFODS team seeks to develop principles for the following five thrusts: principles for complex learning tasks; principles for efficient optimization (convex, non-convex, and submodular); principles for streaming, distributed, and massively parallel data analysis; principles for privacy-preserving and fairness-preserving data analysis; and principles for reproducible data analysis. Each of these thrusts addresses an important foundational need in data science. These needs range from designing learning algorithms with stronger performance guarantees, and developing principles for optimization in adaptive settings, to developing a fundamental understanding of the tradeoffs between various modern computational resources in data science, as well as developing data science algorithms that guarantee meaningful notions of privacy, fairness, and reproducibility. Each thrust requires interactions among several of the TRIPODS disciplines; several of these thrusts also naturally interact with each other. On the education and training side, the PIFODS team has already initiated several new transdisciplinary courses related to data science that are aimed at developing a common language across disciplines; under the aegis of the Institute, the team will continue to further develop and refine these courses, and will incorporate feedback from these courses to inform the university's emerging transdisciplinary data science curriculum. On the applications side, the PIFODS team will actively engage with applied scientists and practitioners of data science, including both members of the broader university community and selected industry practitioners; these engagements will both help to inform possible additional research thrusts in the future, and help to solve important data-driven problems in society. This project is part of the National Science Foundation's Harnessing the Data Revolution (HDR) Big Idea activity.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.

不断发展的数据科学领域有望为社会带来许多好处：个性化的知识和服务;改善医疗保健;改善个人，组织，国家和国际层面的决策;一个更安全，更公平的社会;等等。然而，实现这些承诺的能力关键取决于为该领域建立正确的基本原则。该项目在宾夕法尼亚大学建立了一个NSF TRIPODS研究所，称为宾夕法尼亚数据科学基础研究所（PIFODS），其目标是汇集来自多个学科的科学家和想法，包括计算机科学，电气工程，统计学和数学，以便共同开发长期持久的数据科学原则，可以在未来几十年内为该领域服务。研究所的主要活动将包括跨学科研究、教育和培训，通过应邀举办的研讨会和讲习班与更广泛的研究界接触，以及与应用科学家和从业人员接触。PIFODS团队旨在为以下五个方面制定原则：复杂学习任务的原则;有效优化的原则（凸，非凸和子模块）;流式，分布式和大规模并行数据分析的原则;隐私保护和公平保护数据分析的原则;以及可重现数据分析的原则。每一个目标都解决了数据科学中一个重要的基础需求。这些需求包括设计具有更强性能保证的学习算法，开发自适应设置中的优化原则，对数据科学中各种现代计算资源之间的权衡进行基本理解，以及开发保证隐私，公平性和可重复性的有意义概念的数据科学算法。每一个推力都需要TRIPODS的几个学科之间的相互作用;其中几个推力也自然地相互作用。在教育和培训方面，PIFODS团队已经启动了几个新的与数据科学相关的跨学科课程，旨在开发跨学科的共同语言;在研究所的主持下，该团队将继续进一步开发和完善这些课程，并将从这些课程中获得反馈，为大学新兴的跨学科数据科学课程提供信息。在应用方面，PIFODS团队将积极与应用科学家和数据科学从业者合作，包括更广泛的大学社区成员和选定的行业从业者;这些合作将有助于为未来可能的其他研究方向提供信息，并有助于解决社会中重要的数据驱动问题。该项目是美国国家科学基金会利用数据革命（HDR）大创意活动的一部分。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
