This repository is a static collection of cheat sheets (images and PDFs) for various machine learning and data science libraries (TensorFlow, Keras, Pandas, NumPy, Scikit-learn, PySpark, etc.). It contains no executable code, no data pipelines, no notebooks, and no analytical models. The last commit was in 2019, and the repository has been inactive since. It serves purely as a reference resource for practitioners, not as a functional software project or data research artifact. There are no reusable components, no data lineage, and no reproducibility possible. The repository is effectively a curated set of external cheat sheets, not a codebase to be analyzed for architecture or engineering quality.
