Detailed Analysis

CourseMarks Score®

9.3 / 10

CourseMarks Score® helps students to find the best classes. We aggregate 18 factors, including freshness, student feedback and content diversity.

Freshness Score

10.0 / 10
This course was last updated on 3/2021.

Course content can become outdated quite quickly. After analysing 71,530 courses, we found that the highest rated courses are updated every year. If a course has not been updated for more than 2 years, you should carefully evaluate the course before enrolling.

Student Feedback

8.2 / 10
We analyzed factors such as the rating (4.6/5) and the ratio between the number of reviews and the number of students, which is a great signal of student commitment.

New courses are hard to evaluate because there are no or just a few student ratings, but Student Feedback Score helps you find great courses even with fewer reviews.

Content Score

9.1 / 10
Video Score: 8.1 / 10
The course includes 3h 25m video content. Courses with more videos usually have a higher average rating. We have found that the sweet spot is 16 hours of video, which is long enough to teach a topic comprehensively, but not overwhelming. Courses over 16 hours of video gets the maximum score.
Detail Score: 9.8 / 10

The top online course contains a detailed description of the course, what you will learn and also a detailed description about the instructor.

Description

Would you like to build predictive models using machine learning? That´s precisely what you will learn in this course “Decision Trees, Random Forests and Gradient Boosting in R.” My name is Carlos Martínez, I have a Ph.D. in Management from the University of St. Gallen in Switzerland. I have presented my research at some of the most prestigious academic conferences and doctoral colloquiums at the University of Tel Aviv, Politecnico di Milano, University of Halmstad, and MIT. Furthermore, I have co-authored more than 25 teaching cases, some of them included in the case bases of Harvard and Michigan.
This is a very comprehensive course that includes presentations, tutorials, and assignments. The course has a practical approach based on the learning-by-doing method in which you will learn decision trees and ensemble methods based on decision trees using a real dataset. In addition to the videos, you will have access to all the Excel files and R codes that we will develop in the videos and to the solutions of the assignments included in the course with which you will self-evaluate and gain confidence in your new skills.
After a brief theoretical introduction, we will illustrate step by step the algorithm behind the recursive partitioning decision trees. After we know this algorithm in-depth, we will have earned the right to automate it in R, using the ctree and rpart functions to respectively construct conditional inference and recursive partitioning decision trees. Furthermore, we will learn to estimate the complexity parameter and to prune trees to increase the accuracy and reduce the overfitting of our predictive models. After building the decision trees in R, we will also learn two ensemble methods based on decision trees, such as Random Forests and Gradient Boosting. Finally, we will construct the ROC curve and calculate the area under such curve, which will serve as a metric to compare the goodness of our models.
The ideal students of this course are university students and professionals interested in machine learning and business intelligence. The course includes an introduction to the decision trees algorithm so the only requirement for the course is a basic knowledge of spreadsheets and R.
I hope you are ready to upgrade yourself and learn to optimize investment portfolios with excel and R. I´ll see you in class!
