Sequential and graph-structured data arise naturally in a wide variety of scientific, engineering, and intelligence problems, such as handwriting and speech recognition, text mining, gene finding, and network analysis. While researchers have recently made significant progress on machine learning methods for processing structured data, these methods are much less accessible to scientists, engineers, and analysts than the better understood statistical learning techniques of classification and regression.This project is researching methods to advance the state of the art in machine learning for structured data, building on recent work in conditional random fields and weighted transducers. The project is also developing a software toolkit to make the results of these advances accessible to researchers working in a wide range of disciplines and application domains. The toolkit will enable users to define, train, and apply models for structured data without requiring advanced expertise in machine learning. The functionality of the toolkit will include methods for specifying features relevant to an application, automatically selecting the most relevant features, adjusting parameters to optimize suitable training objectives, and combining models that pertain to different facets of an application.The software, which will be freely distributed, will be tested with selected users in several application domains, and be carefully documented. The project will thus provide the scientific and engineering community with the first generally usable tool for learning from structured data, serving a role that is parallel to that of the more standard tools for classification and regression that are already widely used.-

顺序数据和图结构数据自然地出现在各种科学、工程和智能问题中，例如手写和语音识别、文本挖掘、基因发现和网络分析。虽然研究人员最近在处理结构化数据的机器学习方法方面取得了重大进展，但与分类和回归等更容易理解的统计学习技术相比，科学家、工程师和分析师更容易使用这些方法。该项目基于最近在条件随机场和加权换能器方面的工作，正在研究如何推进结构化数据机器学习的最新技术。该项目还开发了一个软件工具包，使研究人员可以在广泛的学科和应用领域中使用这些进步的结果。该工具包将使用户能够定义、训练和应用结构化数据的模型，而不需要机器学习方面的高级专业知识。该工具包的功能将包括用于指定与应用程序相关的特征的方法，自动选择最相关的特征，调整参数以优化合适的训练目标，以及组合与应用程序的不同方面相关的模型。该软件将免费分发，将在几个应用领域与选定的用户进行测试，并仔细记录。因此，该项目将为科学和工程界提供第一个普遍可用的工具，用于从结构化数据中学习，其作用与已经广泛使用的分类和回归的更标准的工具平行
