0.3.0

May, 2020

• Metafeature extraction with confidence intervals

• Pydoc fixes and package documentation/code consistency improvements

  • Reformatted 'model-based' group metafeature extraction methods arguments to
    a consistent format (all model-based metafeatures now receive a single
    mandatory argument 'dt_model', and all other arguments are optional
    arguments from precomputations.) Now it is much easier to use those
    methods directly without the main class (mfe) filter, if desired.

  • Now accepting user custom arguments in precomputation methods.

  • Added 'extract_from_model' MFE method, making easy to extract model-based
    metafeatures from a pre-fitted model without using the training data.

• Memory issues

  • Now handling memory errors in precomputations, postcomputations and
    metafeature extraction as a regular exception.

• Categorical attributes one-hot encoding option

  • Added option to encode categorical attributes using one-hot encoding
    instead of the current gray encoding.

• New nan-resilient summary functions

  • All summary functions now can be calculated ignoring 'nan' values, using
    its nan-resilient version.

• Online documentation improvement
