Hi, I'm Alexander, a senior student at ECE NTUA, with a focus on AI. Most of what's here is me trying to understand something by building it myself.
Projects
 | fno-pde A Fourier Neural Operator from scratch, compared with a U-Net and a classical solver on Burgers' and Navier-Stokes. The U-Net wins one-step accuracy on Navier-Stokes. Shown: the FNO rolled out 19 steps against the true vorticity, with the error. |
 | black-hole-ml A C++ geodesic ray tracer for Schwarzschild and Kerr black holes, with small ML models trained on what it produces. Shown: a spinning (Kerr) black hole, ray-traced on a GPU. |
 | Dana_Compiler A compiler for the Dana language (Flex, Bison, LLVM), from the NTUA compilers course. |
