## ⚙️ How Shapash works
**Shapash** is an overlay package for libraries focused on model interpretability. It uses Shap or Lime backend
to compute contributions.
**Shapash** builds upon the various steps required to create a machine learning model, making the results more understandable.
<p align="center">
<img src="https://raw.githubusercontent.com/MAIF/shapash/master/docs/_static/shapash-diagram.png" width="700" title="diagram">
</p>
**Shapash** is suitable for Regression, Binary Classification or Multiclass problem. <br />
It is compatible with numerous models: *Catboost*, *Xgboost*, *LightGBM*, *Sklearn Ensemble*, *Linear models*, *SVM*. <br />
If your model is not in the list of compatible models, it is possible to provide Shapash with local contributions calculated with shap or another method. [Here's](https://github.com/MAIF/shapash/blob/master/tutorial/explainer_and_backend/tuto-expl05-Shapash-using-Fasttreeshap.ipynb) an example of how to provide contributions to Shapash. An [issue](https://github.com/MAIF/shapash/issues/488) has been created to enhance this use case.
Shapash can use category-encoders object, sklearn ColumnTransformer or simply features dictionary. <br />
- Category_encoder: *OneHotEncoder*, *OrdinalEncoder*, *BaseNEncoder*, *BinaryEncoder*, *TargetEncoder*
- Sklearn ColumnTransformer: *OneHotEncoder*, *OrdinalEncoder*, *StandardScaler*, *QuantileTransformer*, *PowerTransformer*
## 🛠 Installation
Shapash is intended to work with Python versions 3.8 to 3.11. Installation can be done with pip:
```bash
pip install shapash
```
In order to generate the Shapash Report some extra requirements are needed.
You can install these using the following command :
```bash
pip install shapash[report]
```
If you encounter **compatibility issues** you may check the corresponding section in the Shapash documentation [here](https://shapash.readthedocs.io/en/latest/installation-instructions/index.html).
## 🕐 Quickstart
The 4 steps to display results:
- Step 1: Declare SmartExplainer Object
> There 1 mandatory parameter in compile method: Model
> You can declare features dict here to specify the labels to display
```python
from shapash import SmartExplainer
xpl = SmartExplainer(
model=regressor,
features_dict=house_dict, # Optional parameter
preprocessing=encoder, # Optional: compile step can use inverse_transform method
postprocessing=postprocess, # Optional: see tutorial postprocessing
)
```
- Step 2: Compile Dataset, ...
> There 1 mandatory parameter in compile method: Dataset
```python
xpl.compile(
x=xtest,
y_pred=y_pred, # Optional: for your own prediction (by default: model.predict)
y_target=yTest, # Optional: allows to display True Values vs Predicted Values
additional_data=xadditional, # Optional: additional dataset of features for Webapp
additional_features_dict=features_dict_additional, # Optional: dict additional data
)
```
- Step 3: Display output
> There are several outputs and plots available. for example, you can launch the web app:
```python
app = xpl.run_app()
```
[Live Demo Shapash-Monitor](https://shapash-demo.ossbymaif.fr/)
- Step 4: Generate the Shapash Report
> This step allows to generate a standalone html report of your project using the different splits
of your dataset and also the metrics you used:
```python
xpl.generate_report(
output_file="path/to/output/report.html",
project_info_file="path/to/project_info.yml",
x_train=xtrain,
y_train=ytrain,
y_test=ytest,
title_story="House prices report",
title_description="""This document is a data science report of the kaggle house prices tutorial project.
It was generated using the Shapash library.""",
metrics=[{"name": "MSE", "path": "sklearn.metrics.mean_squared_error"}],
)
```
[Report Example](https://shapash.readthedocs.io/en/latest/report.html)
- Step 5: From training to deployment : SmartPredictor Object
> Shapash provides a SmartPredictor object to deploy the summary of local explanation for the operational needs.
It is an object dedicated to deployment, lighter than SmartExplainer with additional consistency checks.
SmartPredictor can be used with an API or in batch mode. It provides predictions, detailed or summarized local
explainability using appropriate wording.
```python
predictor = xpl.to_smartpredictor()
```
See the tutorial part to know how to use the SmartPredictor object

It uses Shap or Lime backend\nto compute contributions.\n**Shapash** builds upon the various steps required to create a machine learning model, making the results more understandable.\n\n<p align=\"center\">\n <img src=\"https://raw.githubusercontent.com/MAIF/shapash/master/docs/_static/shapash-diagram.png\" width=\"700\" title=\"diagram\">\n</p>\n\n**Shapash** is suitable for Regression, Binary Classification or Multiclass problem. <br />\nIt is compatible with numerous models: *Catboost*, *Xgboost*, *LightGBM*, *Sklearn Ensemble*, *Linear models*, *SVM*. <br />\n\nIf your model is not in the list of compatible models, it is possible to provide Shapash with local contributions calculated with shap or another method. [Here's](https://github.com/MAIF/shapash/blob/master/tutorial/explainer_and_backend/tuto-expl05-Shapash-using-Fasttreeshap.ipynb) an example of how to provide contributions to Shapash. An [issue](https://github.com/MAIF/shapash/issues/488) has been created to enhance this use case.\n\nShapash can use category-encoders object, sklearn ColumnTransformer or simply features dictionary. <br />\n- Category_encoder: *OneHotEncoder*, *OrdinalEncoder*, *BaseNEncoder*, *BinaryEncoder*, *TargetEncoder*\n- Sklearn ColumnTransformer: *OneHotEncoder*, *OrdinalEncoder*, *StandardScaler*, *QuantileTransformer*, *PowerTransformer*\n\n## \ud83d\udee0 Installation\n\nShapash is intended to work with Python versions 3.8 to 3.11. Installation can be done with pip:\n\n```bash\npip install shapash\n```\n\nIn order to generate the Shapash Report some extra requirements are needed.\nYou can install these using the following command : \n```bash\npip install shapash[report]\n```\n\nIf you encounter **compatibility issues** you may check the corresponding section in the Shapash documentation [here](https://shapash.readthedocs.io/en/latest/installation-instructions/index.html).\n\n## \ud83d\udd50 Quickstart\n\nThe 4 steps to display results:\n\n- Step 1: Declare SmartExplainer Object\n > There 1 mandatory parameter in compile method: Model\n > You can declare features dict here to specify the labels to display\n\n```python\nfrom shapash import SmartExplainer\n\nxpl = SmartExplainer(\n model=regressor,\n features_dict=house_dict, # Optional parameter\n preprocessing=encoder, # Optional: compile step can use inverse_transform method\n postprocessing=postprocess, # Optional: see tutorial postprocessing\n)\n```\n\n- Step 2: Compile Dataset, ...\n > There 1 mandatory parameter in compile method: Dataset\n\n```python\nxpl.compile(\n x=xtest,\n y_pred=y_pred, # Optional: for your own prediction (by default: model.predict)\n y_target=yTest, # Optional: allows to display True Values vs Predicted Values\n additional_data=xadditional, # Optional: additional dataset of features for Webapp\n additional_features_dict=features_dict_additional, # Optional: dict additional data\n)\n``` \n\n- Step 3: Display output\n > There are several outputs and plots available. for example, you can launch the web app:\n\n```python\napp = xpl.run_app()\n```\n\n[Live Demo Shapash-Monitor](https://shapash-demo.ossbymaif.fr/)\n\n- Step 4: Generate the Shapash Report\n > This step allows to generate a standalone html report of your project using the different splits\n of your dataset and also the metrics you used:\n\n```python\nxpl.generate_report(\n output_file=\"path/to/output/report.html\",\n project_info_file=\"path/to/project_info.yml\",\n x_train=xtrain,\n y_train=ytrain,\n y_test=ytest,\n title_story=\"House prices report\",\n title_description=\"\"\"This document is a data science report of the kaggle house prices tutorial project.\n It was generated using the Shapash library.\"\"\",\n metrics=[{\"name\": \"MSE\", \"path\": \"sklearn.metrics.mean_squared_error\"}],\n)\n```\n\n[Report Example](https://shapash.readthedocs.io/en/latest/report.html)\n\n- Step 5: From training to deployment : SmartPredictor Object\n > Shapash provides a SmartPredictor object to deploy the summary of local explanation for the operational needs.\n It is an object dedicated to deployment, lighter than SmartExplainer with additional consistency checks.\n SmartPredictor can be used with an API or in batch mode. It provides predictions, detailed or summarized local\n explainability using appropriate wording.\n\n```python\npredictor = xpl.to_smartpredictor()\n```\nSee the tutorial part to know how to use the SmartPredictor object\n\n## \ud83d\udcd6 Tutorials\nThis github repository offers many tutorials to allow you to easily get started with Shapash.\n\n\n<details><summary><b>Overview</b> </summary>\n\n- [Launch the webapp with a concrete use case](tutorial/tutorial01-Shapash-Overview-Launch-WebApp.ipynb)\n- [Jupyter Overviews - The main outputs and methods available with the SmartExplainer object](tutorial/tutorial02-Shapash-overview-in-Jupyter.ipynb)\n- [Shapash in production: From model training to deployment (API or Batch Mode)](tutorial/tutorial03-Shapash-overview-model-in-production.ipynb)\n- [Use groups of features](tutorial/common/tuto-common01-groups_of_features.ipynb)\n- [Deploy local explainability in production with SmartPredictor](tutorial/predictor_to_production/tuto-smartpredictor-introduction-to-SmartPredictor.ipynb)\n\n</details>\n\n<details><summary><b>Charts and plots</b> </summary>\n\n- [**Shapash** Features Importance](tutorial/plots_and_charts/tuto-plot03-features-importance.ipynb)\n- [Contribution plot to understand how one feature affects a prediction](tutorial/plots_and_charts/tuto-plot02-contribution_plot.ipynb)\n- [Summarize, display and export local contribution using filter and local_plot method](tutorial/plots_and_charts/tuto-plot01-local_plot-and-to_pandas.ipynb)\n- [Contributions Comparing plot to understand why predictions on several individuals are different](tutorial/plots_and_charts/tuto-plot04-compare_plot.ipynb)\n- [Visualize interactions between couple of variables](tutorial/plots_and_charts/tuto-plot05-interactions-plot.ipynb)\n- [Display True Values Vs Predicted Values](tutorial/plots_and_charts/tuto-plot06-prediction_plot.ipynb)\n- [Customize colors in Webapp, plots and report](tutorial/common/tuto-common02-colors.ipynb)\n\n</details>\n\n<details><summary><b>Different ways to use Encoders and Dictionaries</b> </summary>\n\n- [Use Category_Encoder & inverse transformation](tutorial/use_encoders/tuto-encoder01-using-category_encoder.ipynb)\n- [Use ColumnTransformers](tutorial/use_encoders/tuto-encoder02-using-columntransformer.ipynb)\n- [Use Simple Python Dictionnaries](tutorial/use_encoders/tuto-encoder03-using-dict.ipynb)\n\n</details>\n\n<details><summary><b>Displaying data with postprocessing</b> </summary>\n\n[Using postprocessing parameter in compile method](tutorial/postprocess/tuto-postprocess01.ipynb)\n\n</details>\n\n<details><summary><b>Using different backends</b> </summary>\n\n- [Compute Shapley Contributions using **Shap**](tutorial/explainer_and_backend/tuto-expl01-Shapash-Viz-using-Shap-contributions.ipynb)\n- [Use **Lime** to compute local explanation, Summarize-it with **Shapash**](tutorial/explainer_and_backend/tuto-expl02-Shapash-Viz-using-Lime-contributions.ipynb)\n- [Compile faster Lime and consistency of contributions](tutorial/explainer_and_backend/tuto-expl04-Shapash-compute-Lime-faster.ipynb)\n- [Use **FastTreeSHAP** or add contributions from another backend](tutorial/explainer_and_backend/tuto-expl05-Shapash-using-Fasttreeshap.ipynb)\n- [Use Class Shapash Backend](tutorial/explainer_and_backend/tuto-expl06-Shapash-custom-backend.ipynb)\n\n</details>\n\n<details><summary><b>Evaluating the quality of your explainability</b> </summary>\n\n- [Building confidence on explainability methods using **Stability**, **Consistency** and **Compacity** metrics](tutorial/explainability_quality/tuto-quality01-Builing-confidence-explainability.ipynb)\n\n</details>\n\n<details><summary><b>Generate a report of your project</b> </summary>\n\n- [Generate a standalone HTML report of your project with generate_report](tutorial/generate_report/tuto-shapash-report01.ipynb)\n\n</details>\n\n<details><summary><b>Analysing your model via Shapash WebApp</b> </summary>\n\n- [Add features outside of the model for more exploration options](tutorial/generate_webapp/tuto-webapp01-additional-data.ipynb)\n\n</details>\n\n## \ud83e\udd1d Contributors\n\n<div align=\"left\">\n <div style=\"display: flex;
