XtoY

pip install xtoy

Go from 'X' to 'y' without effort.

from sklearn.datasets import load_diabetes
from xtoy.toys import Toy
X, y = load_diabetes(return_X_y=True)
toy = Toy()
toy.fit(X[:300], y[:300])
toy.predict(X[300:])

Tries to minimize time-to-first-model

And a reasonable one at that.

Check how important each variable is:

# names of variables are numbers - only in this example - otherwise usually strings
toy.best_features_()
[(0.02541263748358529, 4),
 (0.03964045497300279, 6),

For further inspection, have a look at the pipeline and how important each variable is:

Guarantee

The goal will be to accept ANY data and come up with a "sensible" prediction.

If your dataset doesn't work (asymptotically not happening), post an issue.

Test driven

Quality guarantee by testing code changes, with loss measurements on lots of data problems.

Features

  • ✓ Takes care of encoding text, categorical, dates (several features), continuous
  • Considers data size (small data -> feature engineering, big data -> feature selection)
  • ✓ Takes care of missing values
  • ✓ Creates a model
  • ✓ Optimizes model parameters
  • ✓ Gives you a first prediction
  • ✓ Contains a RegexVectorizer

Roadmap

  • More customizability
  • Tree-based data (being able to exclude grouped variables quickly)
