Generalization error rate of a tree
WebA decision tree algorithm is used to separate the features of a data set via a cost function. The optimization of a decision tree in purpose to eliminate branches that use irrelevant features is known as pruning. By adjusting the depth parameter of the decision tree, the risk of overloading or the complexity of the algorithm can be reduced. WebAnswer to Solved Consider the decision tree shown below: a. Compute
Generalization error rate of a tree
Did you know?
For supervised learning applications in machine learning and statistical learning theory, generalization error (also known as the out-of-sample error or the risk) is a measure of how accurately an algorithm is able to predict outcome values for previously unseen data. Because learning algorithms are evaluated on finite samples, the evaluation of a learning algorithm may be sensitive to sampling error. As a result, measurements of prediction error on the current data ma… WebFeb 11, 2010 · Disturbance plays a fundamental role in determining the vertical structure of vegetation in many terrestrial ecosystems, and knowledge of disturbance histories is vital for developing effective management and restoration plans. In this study, we investigated the potential of using vertical vegetation profiles derived from discrete-return lidar to predict …

WebAnswer: Entropy (t)= -∑ p ( j t)log p ( j t) =- [1020log21020+1020log21020] =1. (b) Compute the Entropy for the Movie ID attribute. Answer: The movie id is unique to each movie. The Entropy for each Movie ID value is 0, hence the entropy for the Movie ID attribute is 0. (c) Compute the Entropy for the Format attribute.
