Improving the DF-Louvain Algorithm through Random Walk-Based Refinement
Published in 2025 RIVF International Conference on Computing and Communication Technologies, 2025
RWGP-DF augments Dynamic Frontier Louvain with a local random-walk refinement that proposes community splits after structural changes and accepts them when modularity improves.

Python Data Science and Machine Learning
Teaching Assistant, PlusPlus Academy, 2021
I taught Python data-science and machine-learning libraries, including NumPy, Pandas, Scikit-learn, PyTorch, and TensorFlow, to a class of 15 students. I also guided algorithm implementation and evaluated final machine-learning and computer-vision projects.
