Course details :

Learn to solve binary and multi-class classification models using machine learning algorithms that are easily understood and readily interpretable. You will learn to write a classification algorithm from scratch, and appreciate the mathematical foundations underpinning logistic regressions and nearest neighbors algorithms.

We strongly recommend that you complete the Regression Models workshop prior to taking this course. Upon completion of this workshop, you will acquire the depth to develop, apply, and evaluate two highly versatile algorithms widely used today.

Graded Quiz

Learning-by-Building Module (3 Points)

Logistic Regression on Credit Risk

  • Applying what you’ve learned, present a simple R Markdown document in which you demonstrate the use of logistic regression on the lbb_loans.csv dataset. Explain your findings wherever necessary and show the necessary data preparation steps. To help you through the exercise, consider the following questions throughout the document:
    • How do we correctly interpret the negative coefficients obtained from your logistic regression?
    • How do we know which of the variables are more statistically significant as predictors?
    • What are some strategies to improve your model?

Customer Segment Prediction

  • Applying what you’ve learned, present a simple R Markdown document in which you demonstrate the use of k-NN on the wholesale.csv dataset. Compare the k-NN to the logistic regression model and answer the following questions throughout the document:
    • What is your accuracy? Was the logistic regression better than k-NN in terms of accuracy? (recall the lesson on obtaining an unbiased estimate of the model’s accuracy)
    • Was the logistic regression better than our kNN model at explaining which of the variables are good predictors of a customer’s industry?
    • List down 1 disadvantage and 1 strength of each of the approach (k-NN and logistic regression)

This workshop is recommended for:

The Machine Learning: Classification 1 workshop is an intermediate-level programming workshop best suited to R programmers that are taking their first steps into data science and machine learning.

Students are assumed to have a working knowledge of R and have completed the necessary pre-requisites. Consider taking the pre-requisite course or a beginner-level course instead if you have no prior programming experience or statistics knowledge.

Past Workshops in this Series:

Students work through tons of real-life examples using sample datasets donated by our team of mentors and corporate partners. We believe in a learn-by-building approach, and we employ instructors who are uncompromisingly passionate about your growth and education.

Part of the Machine Learning Specialization

This workshop is part of the Machine Learning Specialization offered by Algoritma Data Science Academy. Participants are rewarded with a certificate of completion upon passing criteria, and are encouraged to advance further in the respective data science specialization.
