EAGER: Models, analytics, and algorithms for data driven applications

随着我们收集数据的能力不断增强，成本不断降低，数据驱动型应用程序正变得越来越普遍。这类应用的例子包括社交网络(Twitter、Facebook等)、生物信息学(基因调控网络、基因组序列分析)和使用无线传感器网络的环境监测。随着越来越多的数据库可用，如何将数据转换为可操作的信息来指导决策是一个悬而未决的问题，将有许多应用。除了“大”之外，数据和潜在现象还表现出时变性，这增加了从数据中收集有用信息的难度。为了应对这些挑战，该项目将使用动态贝叶斯网络开发一个灵活的算法框架，它可以充分描述物理现实，同时具有足够的表达能力，允许基于机器的学习、优化、推理和适应动态数据。这样的计算框架可以连续、自适应地吸收数据，并将数据简化为符合逻辑、直观和易于人类交互的信息格式。这种特征对于大规模的数据密集型工程系统和网络尤其需要，例如利用基因调控网络进行结构健康监测、监测和疾病发现。智力优势：拟议的项目将建立在图形模型现有工作的基础上，并探索基于测量数据学习动态图形模型的很大程度上的开放领域。将根据凸优化公式开发算法，用于图形模型的在线适配。部分已知的结构信息，以及与噪声、不完整、损坏或丢失的数据有关的问题将被检查。这项拟议的研究将促进从动态数据中学习的艺术的地位，并探索信号处理与信息论、统计学和机器学习之间许多未被探索的联系。广泛的影响：拟议的研究将为基于数据的应用开发通用模型和分析工具。它还将生成低复杂度的算法，这些算法可以适用于大量应用，如无线传感器网络、基因调控网络和基因组序列分析。这项研究将允许通过数字技术获得的数据由计算机自动转换为信息，然后人类可以理解并对其采取行动。这一拟议项目的教育目标是将研究与教育活动有效地结合起来，并培养跨学科领域的本科生和研究生，以培养下一代工程师。将努力邀请出席人数不足的妇女和少数族裔本科生参加拟议的研究。

Data driven applications are becoming increasingly prevalent as our ability to collect data continue to increase and the cost continues to decrease. Examples of such applications include social networks (twitter, facebook, etc.), bioinformatics (gene regulatory networks, genomic sequence analysis), and environmental monitoring using wireless sensor networks. As more databecome available, how to convert data to actionable information to guide decision is a pending problem that will have many applications. In addition to being "big", the data and underlying phenomena also exhibit time-variations which add to thedifficulty of gleaning useful information from data. To cope with these challenges, this project will develop an flexible algorithmic framework using Dynamic Bayesian Networks, which can sufficiently describe the physical reality, and at the same time are expressive enough to allow for machine based learning, optimization, inference and adaptation to dynamical data. Such a computational framework can assimilate data continuously, adaptively, and reduce the data to information ina format that is logical, intuitive, and amenable to human interactions.Such features are particularly needed for large-scale,data-intensive engineering systems and networks such as structural health monitoring, surveillance and disease discovery using gene regulatory networks. Intellectual Merit:The proposed project will build on existing work on graphical models and explore the largely open area of learning dynamical graphical models based on measured data. Algorithms will be developed based on convex optimization formulation for onlineadaptation of the graphical models. Partially known structural information, and issues with noisy, incomplete, corrupted, or missing data will be examined. The proposed research will advance the status of the art of learning from dynamical data,and explore the many under-explored connections between signal processing, and information theory, statistics,and machine learning.Broader Impact: The proposed research will develop generic models and analytical tools for data based applications. It will also generate low-complexity algorithms that can be adapted to a large number of applications such aswireless sensor networks, gene-regulatory networks, and genomic sequence analysis. The research will allow datathat are made available through digital technologies to be converted to information automatically by computers,which can then be understood and acted upon by humans. The educationalgoal of this proposed project is to efficientlintegrate research with educational activities and to train both undergraduate and graduate students in interdisciplinaryareas to produce next-generation engineers. Efforts will be made to invite women, underpresented, and minority undergraduatestudents to participate in the proposed research.
