decision tree multiple choice questions

B) Less than x11 a) Possible Scenarios can be added Answer: D. 1. Only one observation is misclassified, one negative class is showing at the left side of vertical line which will be predicting as a positive class. If the data are not properly discretized, then a decision tree algorithm can give inaccurate results and will perform badly compared to other algorithms. The manner of illustrating often proves to be decisive when making a choice. This activity contains 21 questions. To prevent overfitting, since the complexity of the overall learner increases at each step. b) False You set half the data for training and half for testing initially. Now, Think that each estimators have 70% accuracy. The nodes in the graph represent an event or choice and the edges of the graph represent the decision rules or conditions. This set of Data Structure Multiple Choice Questions & Answers (MCQs) focuses on “AVL Tree”. Consider the following figure for answering the next few questions. And you first split the data based on feature X1(say splitting point is x11) which is shown in the figure using vertical line. d. simulating trends in data. Decision tree with multiple decision points Aa Aa E Free Spirit Industries Inc. is planning to add a new product line to make iToys. Home » multiple choice question machine learning. D) Temperature. Chapter 7: Multiple choice questions. Please choose the best answer for the following questions:- 1. C) Both algorithms can handle real valued attributes by discretizing them What is an AVL tree? Classification. multiple choice question machine learning . top root node. The 2-3 trees is a balanced tree. For this problem, build your own decision tree to confirm your understanding. Multi-output problems¶. This set of MCQ questions on trees and their applications in data structure includes multiple-choice questions on algorithms pertaining to binary search tree. When high cardinality problems, gain ratio is preferred over Information Gain technique. This set of MCQ questions on trees and their applications in data structure includes multiple-choice questions on algorithms pertaining to binary search tree. ... b. a decision tree. Starting with weak learners implies the final classifier will be less likely to overfit. D) None of these. 3. This trait is particularly important in business context when it comes to explaining a decision to stakeholders. D) None of these. The theoretical view is that the review … 29) In which of the following scenario a gain ratio is preferred over Information Gain? C) Extra Trees Tests are chosen using a heuristic called the maximum information-gain (Quinlan, 1986), which tries to build a simple tree that fits the training set. There are two key tech-nical challenges to overcome in learning such a tree struc-ture. Hi, 9 Free Data Science Books to Add your list in 2020 to Upgrade Your Data Science Journey! We request you to post this comment on Analytics Vidhya's, 30 Questions to test a data scientist on Tree Based Models, Both methods can be used for classification task, Random Forest is use for classification whereas Gradient Boosting is use for regression task, Random Forest is use for regression whereas Gradient Boosting is use for Classification task, Both methods can be used for regression task, Lower is better parameter in case of same validation accuracy, Higher is better parameter in case of same validation accuracy, Increase the value of max_depth may overfit the data, Increase the value of max_depth may underfit the data, Number of tree should be as large as possible, You will have interpretability after using RandomForest. Data Mining Interview Questions Certifications in Exam syllabus This trait is particularly important in business context when it comes to explaining a decision to stakeholders.
