Jun 2014 - Dec 2020
A Python implementation of global optimization with gaussian processes.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:7 releases, 132 commits, 87 PRs in 6 years 7 months
Contributions summary:Fernando primarily focused on developing the core classes and optimization algorithms for Bayesian optimization. The user implemented Gaussian Process (GP) class with multiple kernels. They developed a Bayes class, which leverages the GP class for optimization, including methods for maximizing functions and initializing points. The user's work demonstrates a strong focus on the mathematical and computational aspects of the Bayesian optimization process.

A Python Package to Tackle the Curse of Imbalanced Datasets in Machine Learning
Role in this project:Data Scientist
Data ScientistContributions:52 commits, 17 PRs, 36 pushes in 1 year 9 months
Contributions summary:Fernando primarily contributed to the `imbalanced-learn` repository, a Python package for addressing imbalanced datasets in machine learning. Their work involved refining and improving SMOTE (Synthetic Minority Over-sampling Technique) and its variations, including borderline SMOTE and SVM-SMOTE. The user made code changes related to the implementation of SMOTE algorithms, including bug fixes, code cleanup, and incorporating improvements for PEP8 compliance, enhancing the functionality of the oversampling methods. They also refactored SMOTE variations into one object.
