Hi, I'm Derek

Recent graduate1 broadly interested in optimization, machine learning, and scientific computing, mainly using Python, C++, and C. Most of my personal and professional work is in Python, although lately I find myself using C++, namely C++17, more and more.

For fun, here's a toy norm-constrained convex optimization problem and a plot of its solution against the objective's minimum. The Python script used to solve the problem and generate the plot can be found in my profile repository.

Recent activity

numpy-lapacke-demo

Python C extension implementations of linear regression using QR/SVD and Newton's method with diagonal Hessian modification using the Python C API and NumPy C API to work with Python objects on the C level. Computations are done using CBLAS/LAPACKE routines operating directly on NumPy array memory. All public and private methods are rigorously unit tested using pytest.
