Hi, I'm Nicolás Meléndez, a mathematics student at Universidad de los Andes in Bogotá.
My main mathematical interest is spectral theory. I'm currently studying Sturm-Liouville operators and working on a formal verification of the spectral theorem in Lean 4.
I also spend a lot of time with the mathematical and computational foundations of machine learning, with a particular focus on large language models. My interests include probabilistic modeling, empirical risk minimization, stochastic optimization, transformer architectures, and implementing small-scale models from scratch.
On the technical side, I work with Python for scientific computing and machine learning, especially NumPy, SciPy, PyTorch, and scikit-learn. I also use R, SQL, and some Rust. I enjoy Linux, Bash, and anything close to the system.
