README
"One of the holy grails of machine learning is to automate more and more of the feature engineering process." ― Pedro Domingos, A Few Useful Things to Know about Machine Learning
[Featuretools](https://www.featuretools.com) is a python library for automated feature engineering. See the [documentation](https://docs.featuretools.com) for more information.
## Installation
Install with pip
```
python -m pip install featuretools
```
or from the Conda-forge channel on [conda](https://anaconda.org/conda-forge/featuretools):
```
conda install -c conda-forge featuretools
```
### Add-ons
You can install add-ons individually or all at once by running:
```
python -m pip install "featuretools[complete]"
```
**Premium Primitives** - Use Premium Primitives from the premium-primitives repo
```
python -m pip install "featuretools[premium]"
```
**NLP Primitives** - Use Natural Language Primitives from the nlp-primitives repo
```
python -m pip install "featuretools[nlp]"
```
**Dask Support** - Use Dask to run DFS with njobs > 1
```
python -m pip install "featuretools[dask]"
```
## Example
Below is an example of using Deep Feature Synthesis (DFS) to perform automated feature engineering. In this example, we apply DFS to a multi-table dataset consisting of timestamped customer transactions.
```python
>> import featuretools as ft
>> es = ft.demo.load_mock_customer(return_entityset=True)
>> es.plot()
```
Featuretools can automatically create a single table of features for any "target dataframe"
```python
>> feature_matrix, features_defs = ft.dfs(entityset=es, target_dataframe_name="customers")
>> feature_matrix.head(5)
```
```
zip_code COUNT(transactions) COUNT(sessions) SUM(transactions.amount) MODE(sessions.device) MIN(transactions.amount) MAX(transactions.amount) YEAR(join_date) SKEW(transactions.amount) DAY(join_date) ... SUM(sessions.MIN(transactions.amount)) MAX(sessions.SKEW(transactions.amount)) MAX(sessions.MIN(transactions.amount)) SUM(sessions.MEAN(transactions.amount)) STD(sessions.SUM(transactions.amount)) STD(sessions.MEAN(transactions.amount)) SKEW(sessions.MEAN(transactions.amount)) STD(sessions.MAX(transactions.amount)) NUM_UNIQUE(sessions.DAY(session_start)) MIN(sessions.SKEW(transactions.amount))

```
We now have a feature vector for each customer that can be used for machine learning. See the [documentation on Deep Feature Synthesis](https://featuretools.alteryx.com/en/stable/getting_started/afe.html) for more examples.
Featuretools contains many different types of built-in primitives for creating features. If the primitive you need is not included, Featuretools also allows you to [define your own custom primitives](https://featuretools.alteryx.com/en/stable/getting_started/primitives.html#defining-custom-primitives).
## Demos
**Predict Next Purchase**
[Repository](https://github.com/alteryx/open_source_demos/blob/main/predict-next-purchase/) | [Notebook](https://github.com/alteryx/open_source_demos/blob/main/predict-next-purchase/Tutorial.ipynb)
In this demonstration, we use a multi-table dataset of 3 million online grocery orders from Instacart to predict what a customer will buy next. We show how to generate features with automated feature engineering and build an accurate machine learning pipeline using Featuretools, which can be reused for multiple prediction problems. For more advanced users, we show how to scale that pipeline to a large dataset using Dask.
For more examples of how to use Featuretools, check out our [demos](https://www.featuretools.com/demos) page.
