When Does Overfitting Decrease Prediction Accuracy in Induced Decision Trees and Rule Sets?
نویسنده
چکیده
As I have noted, these calculations yield the expected observed accuracy of S s and S c , counting a prediction model as successful when its predictions match the apparent class of new objects. To calculate the accuracy of these strategies in predicting the true class of new objects, simply let n 0 c =0. 8 Acknowledgements Thanks to Tom Ellman, who suggested viewing noise as a model shift in the p 1-p 2 plane.

MMDT: Multi-Objective Memetic Rule Learning from Decision Tree
In this article, a Multi-Objective Memetic Algorithm (MA) for rule learning is proposed. Prediction accuracy and interpretation are two measures that conflict with each other. In this approach, we consider accuracy and interpretation of rules sets. Additionally, individual classifiers face other problems such as huge sizes, high dimensionality and imbalance classes’ distribution data sets. This...
متن کاملDecision Forests with Oblique Decision Trees
Ensemble learning schemes have shown impressive increases in prediction accuracy over single model schemes. We introduce a new decision forest learning scheme, whose base learners are Minimum Message Length (MML) oblique decision trees. Unlike other tree inference algorithms,MMLoblique decision tree learning does not over-grow the inferred trees. The resultant trees thus tend to be shallow and ...
متن کاملCombining machine learning and expert knowledge for classifying human posture
This paper presents a rule engine for classifying human posture according to information about the location of body parts. The rule engine was developed by enriching decision trees with expert knowledge. Results show 5 percentage points improvement in accuracy compared to support vector machines and a significant 11 percentage points compared to decision trees. The incorporation of expert knowl...
متن کاملHow to Mine Information from Each Instance to Extract anAbbreviated and Credible Logical Rule
Decision trees are particularly promising in symbolic representation and reasoning due to their comprehensible nature, which resembles the hierarchical process of human decision making. However, their drawbacks, caused by the single-tree structure, cannot be ignored. A rigid decision path may cause the majority class to overwhelm other class when dealing with imbalanced data sets, and pruning r...
متن کاملBuilding classification trees using the total uncertainty criterion
We present an application of the measure of total uncertainty on convex sets of probability distributions, also called credal sets, to the construction of classification trees. In these classification trees the probabilities of the classes in each one of its leaves is estimated by using the imprecise Dirichlet model. In this way, smaller samples give rise to wider probability intervals. Branchi...
