Building models that actually generalise.

MSc in Data Analysis & Engineering

About

My journey into machine learning started through mathematics, where I became fascinated by how theory translates into real-world predictive systems.

I focus on building models that not only perform well, but generalise reliably.

Currently pursuing a MSc in Data Analysis & Engineering, specialising in optimisation and deep learning.

Side Projects

Pokemon Classifier

Developed a classification model designed to identify Pokémon in complex environments. The project consisted in Feature engineering and data augmentation, utilized Multi-Layer Perceptrons (MLPs) and then Convolutional Neural Networks (CNNs) to optimize accuracy and model generalization.

PythonPyTorchScikitLearn

Multiple Myeloma Survival

Conducted predictive modeling to estimate survival timelines for patients diagnosed with Multiple Myeloma. Applied dimensionality reduction techniques like Isomap and non-parametric algorithms such as K-Nearest Neighbors (KNN). Analyzed high-dimensional clinical data to identify key prognostic factors and enhance survival probability forecasting.
