Deployment

Deployment of machine learning models requires repeating feature engineering steps on new data. In some cases, these steps need to be performed in near real-time. Featuretools has capabilities to ease the deployment of feature engineering.

Saving Features

First, let’s build some generate some training and test data in the same format. We use a random seed to generate different data for the test.

Note

Features saved in one version of Featuretools are not guaranteed to load in another. This means the features might need to be re-created after upgrading Featuretools.

In [1]: import featuretools as ft

In [2]: es_train = ft.demo.load_mock_customer(return_entityset=True)

In [3]: es_test = ft.demo.load_mock_customer(return_entityset=True, random_seed=33)

Now let’s build some features definitions using DFS. Because we have categorical features, we also encode them with one hot encoding based on the values in the training data.

In [4]: feature_matrix, feature_defs = ft.dfs(entityset=es_train,
   ...:                                       target_entity="customers")
   ...: 

In [5]: feature_matrix_enc, features_enc = ft.encode_features(feature_matrix, feature_defs)

In [6]: feature_matrix_enc

Now, we can use featuretools.save_features() to save a list features to a json file

In [7]: ft.save_features(features_enc, "feature_definitions.json")

Calculating Feature Matrix for New Data

We can use featuretools.load_features() to read in a list of saved features to calculate for our new entity set.

In [8]: saved_features = ft.load_features('feature_definitions.json')

After we load the features back in, we can calculate the feature matrix.

In [9]: feature_matrix = ft.calculate_feature_matrix(saved_features, es_test)

In [10]: feature_matrix

As you can see above, we have the exact same features as before, but calculated using the test data.

Exporting Feature Matrix

Save as csv

The feature matrix is a pandas dataframe that we can save to disk

In [11]: feature_matrix.to_csv("feature_matrix.csv")

We can also read it back in as follows:

In [12]: saved_fm = pd.read_csv("feature_matrix.csv", index_col="customer_id")

In [13]: saved_fm
Out[13]:
