Unsupervised Learning-The input data in machine learning isn’t labelled and the output isn’t known. The aim ofunsupervised learningis find the hidden structures within the data. One main class of problem associated with unsupervised learning is Clustering, which uses the inherent structures of dat...

As machine learning, a subset of artificial intelligence, has inspired numerous breakthroughs, a recent surge in interest in this field is observed across a wide variety of disciplines. This chapter aims to point out some of the main concepts and models of this attractive area of research while...
The chapter uses a simple example to review some basic problem structure, nomenclature, and characteristics of a machine learning data set. The language introduced in this section will be used throughout the rest of the book. After establishing some common language, the chapter goes one by one ...
Training Data: S={(x1,y1),⋯,(xm,ym)} 是一个有限长度的序列对,其中每一个点都来自 X×Y ,我们将训练数据输入给Learner用于训练, S 通常被称为训练集输出:Learner的输出是一个预测的规则,也就是一个函数 h:X→Y ,这个输出可以被称为predictor、hypothesis或者classifier...
