We are a group of passionate data scientists and software developers with the mission to make intermediate and advanced topics on machine learning, data science and AI software engineering accessible to the wider data science community.
We create intermediate and advanced online courses on machine learning, data science and AI software development. We also maintain an open-source library for feature engineering: Feature-engine.
In addition, we talk, blog and participate in podcasts about machine learning, software development and open-source.
Check out the courses that we teach.
| Courses | What you will learn |
|---|---|
| Feature engineering for machine learning | Learn to create new features, impute missing data, encode categorical variables, transform and discretize features and much more. |
| Feature selection for machine learning | Learn to select features using wrapper, filter, embedded and hybrid methods, and build simpler and reliable models. |
| Hyperparameter optimization for machine learning | Learn about grid and random search, Bayesian Optimization, Multi-fidelity models, Optuna, Hyperopt, Scikit-Optimize and more. |
| Machine learning with imbalanced data | Learn about under- and over-sampling, ensemble and cost-sensitive methods and improve the performance of models trained on imbalanced data. |
| Feature engineering for time series forecasting | Learn to create lag and window features, impute data in time series, encode categorical variabes and much more, specifically for forecasting. |
| Forecasting with Machine Learning | Learn to perform time series forecasting with machine learning models like linear regression, random forests and xgboost. |
| Machine Learning Interpretability | Learn to interpret the predictions of your white box and black box machine learning models. |
