Python for brain mining: (neuro)science with state of the art machine learning and data visualization by Gaël Varoquaux.
Brief slide deck on three tools:
Mayavi: For 3-D visualizations.
scikit-learn, which we reported on at: scikits.learn machine learning in Python.
Joblib: running Python function as pipeline jobs.
All three look useful, although I suspect Joblib may be the one of more immediate interest.
Depends on your interests. Comments?
