Course Description

Did you know that approximately 70% of data science problems involve classification and logistic regression is a common solution for binary problems?

Logistic regression has many applications in data science, but in the world of healthcare, it can really drive life-changing action.

In this SuperDataScience case study course, learn how to detect breast cancer by applying a logistic regression model on a real-world dataset and predict whether a tumor is benign (not breast cancer) or malignant (breast cancer) based off its characteristics.

By the end of the course, you will be able to build a logistic regression model to identify correlations between the following 9 independent variables and the class of the tumor (benign or malignant).


  • Clump thickness

  • Uniformity of cell size

  • Uniformity of cell shape

  • Marginal adhesion

  • Single epithelial cell

  • Bare Nuclei

  • Bland chromatin

  • Normal nucleoli

  • Mitoses

Logistic regression can identify important predictors of breast cancer using odds ratios and generate confidence intervals that provide additional information for decision-making. Model performance depends on the ability of the radiologists to accurately identify findings on mammograms.

Join AI expert Hadelin de Ponteves as you code the solution along with him in this 1-hour, 3-part case study:

Part 1: Data Preprocessing

  • Importing the dataset

  • Splitting the dataset into a training set and test set

Part 2: Training and Inference

  • Training the logistic regression model on the training set

  • Predicting the test set results

Part 3: Evaluating the Model

  • Making the confusion matrix

  • Computing the accuracy with k-Fold cross-validation

Testing your skills with practical courses is one of the best and most enjoyable ways to learn data science…and now we’re giving you that chance for FREE.

Plus, you’ll do it all using Google’s Colab free, browser-based notebook environment that runs completely in the cloud. It’s a game-changing interface that will save you time and supercharge your data science toolkit.

More about logistic regression:

Logistic regression is a method of statistical analysis used to predict a data value based on prior observations of a dataset. A logistic regression model predicts the value of a dependent variable by analyzing the relationship between one or more existing independent variables.

In data science, logistic regression is a Machine Learning algorithm used for classification problems and predictive analysis.

More real-world applications of logistical regression include:

  • Bankruptcy predictions

  • Credit scoring

  • Consumer behavior

  • Customer retention

  • Spam detection

Good case study. While as a small piece of logistic regression focused lecture, too much too fundamental staffs. I mean, for zero basis learners, it is not good to start from logistic regression case study directly, while for learners with some foundations like me (I was directed here from the Machine Learning A-Z course, which is good for beginners), this lecture is not concise enough. But overall, amazing course!

learning about Artificial Neural Networks (ANN) was a downright fascinating experience. These fancy networks, inspired by the human brain, sure do shine in things like image and speech recognition and natural language processing. My teacher made the whole complicated mess feel as simple as sweet tea on a hot day. Now, don’t get me wrong, training these ANNs still takes a heap of computational power and loads of data, which ain't always easy to come by. But despite that, their abilities are truly impressive and keep pushing the envelope.

Sometimes some student don't provide review the main reason for that is they want to complete course as soon as possible. This criteria of students include me also. But Now after watching all this videos i think i should give a sincere feedback. I would really like to thank Kirill & Hadelin . Teachers like this are really needed to understand any basic concepts. Their ways of teaching of by practical implication is really a good way in which any student can grap these concepts.

It's a great course with real world cases where I get to understand what the problems are and how to solve them. Very practical. I got this course from Machine Learning A to Z which was delivered by the same instructor Hadelin and he's a very good teacher and always made everything easy to learn.

By Hiroki Fujiwara on 7/30/2023

I must say that it was an extremely enriching experience. The instructor has managed to strike the perfect balance between theory and application, making this complex statistical concept very accessible. The practical case study used to illustrate logistic regression was thoughtfully chosen. It helped me to see how this technique can be applied in a real-world scenario, and I found the step-by-step approach to building and evaluating the model particularly helpful. I especially appreciated the inclusion of code snippets, the guidance on data preprocessing, and the attention to model evaluation metrics. It wasn't just about getting the model to work; it was about understanding why it worked and how to ensure its reliability. The additional resources and exercises provided at the end of the lecture were the cherry on top, allowing me to deepen my understanding further. This lecture is a must for anyone looking to grasp logistic regression in a hands-on and intuitive way. Thank you for this excellent learning opportunity!

By Richard J Bloch on 10/12/2022

Excellent course , and I like that both Python and R are being used in the course. Some hiccups in the presented information apparently because of updates in "components" of the "languages". New concepts were introduced at times without sufficient explanation but it is still a tremendous learning experience. Very engaging instructors and how to dig information out to aid in one's learning experience. Great Course!!!!!

By Subham Sanket Rout on 9/21/2020

Got an intuition about what can one do after learning the Machine Learning Algorithms. By the way, explanations of the instructor were very clear. Before starting, this real life implementation seemed very difficult to me, but the instructor made it quite easy. Really, it felt way easier than I anticipated. Kudos to Hadelin de Ponteves, Kirill Eremenko and the SuperDataScience team.

By Shivam Rajput on 9/17/2020

I am inspired by what Hadelin De Ponteves sir and Kirill Ermenko sir have created. This course is really great. The machine learning course A-Z is also very great where this course was suggested. I am inspired and very much interested in this field of machine learning. And I hope I can make it my living someday. Thank you very much

By Manik Aggarwal on 6/6/2020

Came to this course after finding the link the link in bigger course bonus section of Machine Learning A-Z. It was a nice hands on for logistic regression. Only thing was, i did not take the dataset from what he described, instead i grabbed it from sklearn.datasets. For this very reason i had to scale the dataset and got more accuracy . Enjoy Machine Learning.

By Roni Ang on 5/12/2020

I kinda jumped into a difficult lesson. I am a very newbie in python coding. I got errors with my code even though i follow the code carefully, it gave me error-message that the codes has not enough iteration and other stuff that I don't understand. Nevertheless, its okay, because I think this lesson motivated me to learn more. This is the most important part. Thank you so much.
