中文简介:
本课程涵盖功能选择的基础和应用。学生将首先被提醒机器学习算法的基础和过度拟合避免的问题。在包装器设置中,特性选择将作为模型选择问题的特殊情况引入。本文综述了基于特征选择原理的特征选择算法的推导方法和启发式方法,这些方法在实际应用中效果良好。有一门课将专门讲授特征构造技术。最后,一节课将专门讨论特征部分和因果发现之间的联系。这门课将会有几个实验课程。这门课程将会吸引那些喜欢玩数据并且想要学习实际数据分析技术的学生。该讲师在美国创业公司的模式识别和机器学习咨询方面有10年的经验。将提供来自各种应用领域的数据集:手写识别、医学诊断、药物发现、文本分类、生态学、营销。
课程简介: This course covers feature selection fundamentals and applications. The students will first be reminded of the basics of machine learning algorithms and the problem of overfitting avoidance. In the wrapper setting, feature selection will be introduced as a special case of the model selection problem. Methods to derive principled feature selection algorithms will be reviewed as well as heuristic method, which work well in practice. One class will be devoted to feature construction techniques. Finally, a lecture will be devoted to the connections between feature section and causal discovery. The class will be accompanied by several lab sessions. The course will be attractive to students who like playing with data and want to learn practical data analysis techniques. The instructor has ten years of experience with consulting for startup companies in the US in pattern recognition and machine learning. Datasets from a variety of application domains will be made available: handwriting recognition, medical diagnosis, drug discovery, text classification, ecology, marketing.
关 键 词: 功能选择基础; 应用程序; 包装器设置
