explainy is a library for generating explanations for machine learning models in Python. It uses methods from Machine Learning Explainability and provides a standardized API to create feature importance explanations for samples. The explanations are generated in the form of plots and text.

**explainy** is a library for generating machine learning models explanations in Python. It uses methods from **Machine Learning Explainability** and provides a standardized API to create feature importance explanations for samples.
The API is inspired by `scikit-learn` and has two core methods `explain()` and `plot()`. The explanations are generated in the form of texts and plots.
**explainy** comes with four different algorithms to create either *global* or *local* and *contrastive* or *non-contrastive* model explanations.
## Documentation
https://explainy.readthedocs.io
## Install explainy
```
pip install explainy
```
## Usage
📚 A comprehensive example of the `explainy` API can be found in this 
📖 Or in the [example section](https://explainy.readthedocs.io/en/latest/examples/01-explainy-intro.html) of the documentation
Initialize and train a `scikit-learn` model:
```python
import pandas as pd
from sklearn.datasets import load_diabetes
from sklearn.ensemble import RandomForestRegressor
from sklearn.model_selection import train_test_split
diabetes = load_diabetes()
X_train, X_test, y_train, y_test = train_test_split(
diabetes.data, diabetes.target, random_state=0
)
X_test = pd.DataFrame(X_test, columns=diabetes.feature_names)
y_test = pd.DataFrame(y_test)
model = RandomForestRegressor(random_state=0).fit(X_train, y_train)
```
Initialize the `PermutationExplanation` (or any other explanation) object and pass in the trained model and the to be explained dataset.
Addtionally, define the number of features used in the explanation. This allows you to configure the verbosity of your exaplanation.
Set the index of the sample that should be explained.
```python
from explainy.explanations import PermutationExplanation
number_of_features = 4
sample_index = 1
explainer = PermutationExplanation(
X_test, y_test, model, number_of_features
)
```
Call the `explain()` method and print the explanation for the sample (in case of a local explanation every sample has a different explanation).
```python
explanation = explainer.explain(sample_index=sample_index)
print(explanation)
```
> The RandomForestRegressor used 10 features to produce the predictions. The prediction of this sample was 251.8.
> The feature importance was calculated using the Permutation Feature Importance method.
> The four features which were most important for the predictions were (from highest to lowest): 'bmi' (0.15), 's5' (0.12), 'bp' (0.03), and 'age' (0.02).
Use the `plot()` method to create a feature importance plot of that sample.
```python
explainer.plot()
```
If your prefer, you can also create another type of plot, as for example a boxplot.
```python
explainer.plot(kind='box')
```
<!-- Finally the result can be saved
```python
explainer.save(sample_index)
``` -->

Description
- **global**: explanation of system functionality (all samples have the same explanation)
- **local**: explanation of decision rationale (each sample has its own explanation)
- **contrastive**: tracing of decision path (differences to other outcomes are described)
- **non-contrastive**: parameter weighting (the feature importance is reported)
## Features
- Algorithms for inspecting black-box machine learning models
- Support for the machine learning frameworks `scikit-learn` and `xgboost`
- **explainy** offers a standrdized API with three core methods `explain()`, `plot()`, `importance()`
