Currently studying MSc in Theoretical Maths, full dissertation with topic of research:
Sums and products of square-zero matrices.
Previously my coursework on postgrad level included Matrix theory and Linear algebra, Graph theory, Set theory, Category theory (introductory level) and Measure and Integration theory (introductory level).
I work in a fintech environment on classification problems, segmentation and sampling. Techniques I use include gradient boosting, logit glm, feature selection with genetic algorithms, PCA, k-means, distance-based methods for determining sampling accuracy, etc. mostly in Python, but also using R.
