4.2 General Approach to Solving a Clvectorication Problem A clvectorication technique (or clvectorier) is a systematic approach to building clvectorication models from an input data set. Examples include decision tree clvectoriers rule-based clvectoriers neural networks support vector machines and nave Bayes clvectoriers.

Clvectorification Basic Concepts Decision Trees and Model Evaluation. Clvectorification Definition Given a collection of records (training set ) Each record contains a set of attributes one of the attributes is the clvector. Find a modelfor clvector attribute as a function of the values of other attributes. Goal previously unseenrecords should be vectorigned a clvector as accurately as possible.

Jeff Howbert Introduction to Machine Learning Winter 2014 2 zGiven a collection of samples (training set) Each sample contains a set of attributes. Each sample also has a discrete clvector label. zLearn a model that predicts clvector label as a function of the values of the attributes. zGoal model should vectorign clvector In this vector you will learn about building a decision tree models for clvectorification problem. Decision tree is a supervised learning algorithm. It can be used to clvectorify data into categories. It
