用 Python 玩 LHC 公開數據
This document discusses using Python to analyze LHC data from CERN's Higgs Boson machine learning challenge on Kaggle. It introduces ROOT and TMVA tools for working with particle physics data in C++ and Python. It also discusses SciPy and Scikit-Learn libraries that can be used for tasks like data preprocessing, machine learning algorithms, and visualization.
