how to create predictive models r using decision trees

What are the disadvantages of using a decision tree for

Decision tree are powerful non-linear classifiers, which utilize a tree structure to model the relationships among the features and the potential outcomes. A decision tree classifier uses a structure of branching decisions, which channel examples into a final predicted class value.

The decision tree model is built on the training set and then the classification accuracy is tested using the validation set. In RapidMiner this is accomplished by using one of the Validation operators (such as Split Validation or Cross Validation). However by splitting the data into three parts: training, validation and holdout further reduces the chances of overfitting the data.

CART A Powerful Decision Tree Tool for Predictive Modeling

Decision trees that split on one input at a time are more tolerant to missing data than models such as regression that combine several inputs. Stratified modeling The analyst preparing for a regression model faces another hidden pitfall when the data represent two populations. In the other extreme. Otherwise.interactions is needed. If the values of Y in one population are all larger than those

Classification And Regression Trees for Machine Learning

The party package is one of several packages in R that create decision trees. (Other common decision-tree packages include rpart , tree , and randomForest .) The next step is to use the package to create a decision-tree model, using seedType as the target variable and all the other variables as predictor variables.

Applied Predictive Modeling in R. At useR! 2014 I'll be doing a morning tutorial (09:15 12:45) on at Monday, 30 June. This course will provide an overview of using R for supervised learning. The session will step through the process of building, visualizing, testing and comparing models that are focused on prediction. The goal of the course is to provide a thorough workflow in R that can

R for Predictive Modeling A Hands-On Introduction

23/12/2013 R allows us to create models given the available information to predict what we want to know. This post will discuss a predictive analysis method, decision trees- a type of non-parametric modeling. Open R and let us get started!

2. Aggregation: The core concept that makes random forests better than decision trees is aggregating uncorrelated trees. The idea is to create several crappy model trees (low depth) and average them out to create a better random forest.
