Ramp - Rapid Machine Learning Prototyping
Ramp is a python module for rapid prototyping of machine learning solutions. It is essentially a pandas wrapper around various python machine learning and statistics libraries (scikit-learn, rpy2, etc.), providing a simple, declarative syntax for exploring features, algorithms and transformations quickly and efficiently.

Why Ramp?
-
Complex feature transformations
Chain and combine features:
Normalize(Log('x')) Interactions([Log('x1'), (F('x2') + F('x3')) / 2])Reduce feature dimension:
SVDDimensionReduction([F('x%d'%i) for i in range(100)], n_keep=20)Incorporate residuals or predictions to blend with other models:
Residuals(config_model1) + Predictions(config_model2)Any feature that uses the target ("y") variable will automatically respect the current training and test sets.
-
Caching
Ramp caches and stores on disk in fast HDF5 format (or elsewhere if you want) all features and models it computes, so nothing is recomputed unnecessarily. Results are stored and can be retrieved, compared, blended, and reused between runs.
-
Easy extensibility
Ramp has a simple API, allowing you to plug in estimators from scikit-learn, rpy2 and elsewhere, or easily build your own feature transformations, metrics, feature selectors, reporters, or estimators.
