Feature importance and model interpretation in Python

Online course

How to calculate the importance of the features and interpret models

Introduction

This course is part of the Supervised Machine Learning in Python online course.

Calculating the importance of the features is mandatory for every machine learning project. It can be used, for example, to reduce the number of features of our dataset by discarding the less useful columns. Moreover, the interpretability and explainability of a model are very important parts of a machine learning pipeline, because they make the model behavior clear and help us to extract information that is hidden inside data. 

That’s why mastering feature importance and model interpretation is crucial for the success of a machine learning project.

Advantages of feature importance

  • Knowledge of our data

    Feature importance gives us a very useful knowledge about our data.

  • Dimensionality reduction

    Knowing the useless features we can reduce the dimensions of our problem, filtering our the noise and only keeping the useful information.

  • Model interpretation

    Several techniques can be used to interpret the results of a model (e.g. SHAP)

My online course

In my online course, I outline all the main topics about feature importance and model interpretation. All the lessons will be covered with practical examples in Python programming language.

These are the topics of the course:

Models that calculate feature importance

Several models calculate feature importance, like Lasso regression, tree-based models and SVM.

SHAP technique

SHAP is a technique that allows us to calculate the importance of the feature in a model-agnostic approach. 

Recursive Feature Elimination (RFE)

Once we have calculated feature importance, it’s useful to use this information for reducing the dimensions of our dataset. RFE can be used for this purpose. 

Python libraries 

Everything will be done using scikit-learn library, imblearn and matplotlib.

Testimonials

The course is excellent and very useful. All major subjects are complete and clear. A "must have" if you want to become a skilled data scientist

Roberto

The teacher

My name is Gianluca Malato, I'm Italian and have a Master's Degree cum laude in Theoretical Physics of disordered systems at "La Sapienza" University of Rome. I'm a Data Scientist who has been working for years in the banking and insurance sector. I have extensive experience in software programming and project management and I have been dealing with data analysis and machine learning in the corporate environment for several years. I am also skilled in data analysis (e.g. relational databases and SQL language), numerical algorithms (e.g. ODE integration, optimization algorithtms) and simulation (e.g. Monte Carlo techniques). I've written many articles about Machine Learning, R and Python and I've been a Top Writer on Medium.com in Artificial Intelligence category.
