        # Pyreal
        
        Library for evaluating and deploying machine learning explanations.
        
        - Free software: Not open source

        # Overview
        
        **Pyreal** wraps the complete machine learning explainability pipeline into Explainer objects. Explainer objects
        handle all the transforming logic, in order to provide a human-interpretable explanation from any original
        data form.
        
        # Install
        
        ## Requirements
        
        **Pyreal** has been developed and tested on [Python3.4, 3.5, 3.6 and 3.7](https://www.python.org/downloads/)
        
        Also, although it is not strictly required, the usage of a [virtualenv](https://virtualenv.pypa.io/en/latest/)
        is highly recommended in order to avoid interfering with other software installed in the system
        in which **Pyreal** is run.
        
        These are the minimum commands needed to create a virtualenv using python3.6 for **Pyreal**:
        
        ```bash
        pip install virtualenv
        virtualenv -p $(which python3.6) pyreal-venv
        ```
        
        Afterwards, you have to execute this command to activate the virtualenv:
        
        ```bash
        source pyreal-venv/bin/activate
        ```
        
        Remember to execute it every time you start a new console to work on **Pyreal**!
        
        <!-- Uncomment this section after releasing the package to PyPI for installation instructions
        ## Install from PyPI
        
        After creating the virtualenv and activating it, we recommend using
        [pip](https://pip.pypa.io/en/stable/) in order to install **Pyreal**:
        
        ```bash
        pip install pyreal
        ```
        
        This will pull and install the latest stable release from [PyPI](https://pypi.org/).
        -->
        
        ## Install from source
        
        With your virtualenv activated, you can clone the repository and install it from
        source by running `make install` on the `stable` branch:
        
        ```bash
        git clone git@github.com:DAI-Lab/pyreal.git
        cd pyreal
        git checkout stable
        make install
        ```
        
        <!--## Install for Development
        
        If you want to contribute to the project, a few more steps are required to make the project ready
        for development.

        # Quickstart
        
        In this short tutorial we will guide you through a series of steps that will help you
        getting started with **Pyreal**. For a more detailed version of this tutorial, see 
        `examples.titanic.titanic_tutorial.ipynb`
        
        ```python3
        from pyreal.explainers import LocalFeatureContribution
        import pyreal.applications.titanic as titanic
        from pyreal.utils.transformer import ColumnDropTransformer, MultiTypeImputer
        from pyreal.utils import visualize
        
        # First, we will load in the Titanic dataset
        x_orig, y = titanic.load_titanic_data()
        
        # Next, we load in a dictionary that provides human-readable descriptions of the feature names
        #   Format: {feature_name : feature_description, ...}
        feature_descriptions = titanic.load_feature_descriptions()
        
        # Finally, we load in the trained model and corresponding fitted transformers
        model = titanic.load_titanic_model()
        transformers = titanic.load_titanic_transformers()
        
        # Now, we can make and fit a LocalFeatureContribution object, which will handle all the 
        #   transformations needed to get an interpretable SHAP feature contribution explanation
        lfc = LocalFeatureContribution(model=model, x_orig=x_orig, m_transforms=transformers, e_transforms=transformers, 
                                       contribution_transforms=transformers, 
                                       feature_descriptions=feature_descriptions)
        lfc.fit()
        
        # We can now choose an input, and see the model's prediction.
        input_to_explain = x_orig.iloc[0]
        print("Prediction:", lfc.model_predict(input_to_explain)) # Output -> Prediction: [0]
        
        # We see that this person is not predicted to survive. 
        #   Let's see why, by using LocalFeatureContribution's .produce() function
        contributions = lfc.produce(input_to_explain)
        
        # We can visualize the most contributing features using the pyreal.utils.visualize module. 
        #   We will also convert our input to the interpretable space, so we can add it's values to
        #   the visualization
        x_interpret = lfc.convert_data_to_interpretable(input_to_explain)
        visualize.plot_top_contributors(contributions, select_by="absolute", values=x_interpret)
        ```
        The output will be a bar plot showing the most contributing features, by absolute value. 
        
        ![Quickstart](docs/images/quickstart.png)
        
        We can see here that the input passenger's predicted chance of survival was greatly reduced
        because of their sex (male) and ticket class (3rd class).
