Neuraxle is a Machine Learning (ML) library for building clean machine learning pipelines using the right abstractions.
- **Component-Based**: Build encapsulated steps, then compose them to build complex pipelines.
- **Evolving State**: Each pipeline step can fit, and evolve through the learning process
- **Hyperparameter Tuning**: Optimize your pipelines using AutoML, where each pipeline step has their own hyperparameter space.
- **Compatible**: Use your favorite machine learning libraries inside and outside Neuraxle pipelines.
- **Production Ready**: Pipeline steps can manage how they are saved by themselves, and the lifecycle of the objects allow for train, and test modes.
- **Streaming Pipeline**: Transform data in many pipeline steps at the same time in parallel using multiprocessing Queues.
Documentation
-------------
You can find the Neuraxle documentation `on the website `_. It also contains multiple examples demonstrating some of its features.
Installation
------------
Simply do:
.. code:: bash
pip install neuraxle
Examples
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We have several `examples on the website `__.
For example, you can build a time series processing pipeline as such:
.. code:: python
p = Pipeline([
TrainOnlyWrapper(DataShuffler()),
WindowTimeSeries(),
])
# Load data
X_train, y_train, X_test, y_test = generate_classification_data()
# The pipeline will learn on the data and acquire state.
p = p.fit(X_train, y_train)
# Once it learned, the pipeline can process new and
# unseen data for making predictions.
y_test_predicted = p.predict(X_test)
You can also tune your hyperparameters using AutoML algorithms such as the TPE:
.. code:: python
# Define classification models with hyperparams.
# All SKLearn models can be used and compared to each other.
# Define them an hyperparameter space like this:
decision_tree_classifier = SKLearnWrapper(
DecisionTreeClassifier(),
HyperparameterSpace({
'criterion': Choice(['gini', 'entropy']),
'splitter': Choice(['best', 'random']),
'min_samples_leaf': RandInt(2, 5),
'min_samples_split': RandInt(2, 4)
}))
# More SKLearn models can be added (code details skipped):
random_forest_classifier = ...
logistic_regression = ...
# It's possible to mix TensorFlow models into Neuraxle as well,
# using Neuraxle-Tensorflow' Tensorflow2ModelStep class, passing in
# the TensorFlow functions like create_model and create_optimizer:
minibatched_tensorflow_classifier = EpochRepeater(MiniBatchSequentialPipeline([
Tensorflow2ModelStep(
create_model=create_linear_model,
create_optimizer=create_adam_optimizer,
create_loss=create_mse_loss_with_regularization
).set_hyperparams_space(HyperparameterSpace({
'hidden_dim': RandInt(6, 750),
'layers_stacked_count': RandInt(1, 4),
'lambda_loss_amount': Uniform(0.0003, 0.001),
'learning_rate': Uniform(0.001, 0.01),
'window_size_future': FixedHyperparameter(sequence_length),
'output_dim': FixedHyperparameter(output_dim),
'input_dim': FixedHyperparameter(input_dim)
}))
]), epochs=42)
# Define a classification pipeline that lets the AutoML loop choose one of the classifier.
# See also ChooseOneStepOf documentation: https://www.neuraxle.org/stable/api/steps/neuraxle.steps.flow.html#neuraxle.steps.flow.ChooseOneStepOf
pipeline = Pipeline([
ChooseOneStepOf([
decision_tree_classifier,
random_forest_classifier,
logistic_regression,
minibatched_tensorflow_classifier,
])
])
# Create the AutoML loop object.
# See also AutoML documentation: https://www.neuraxle.org/stable/api/metaopt/neuraxle.metaopt.auto_ml.html#neuraxle.metaopt.auto_ml.AutoML
auto_ml = AutoML(
pipeline=pipeline,
hyperparams_optimizer=TreeParzenEstimator(
# This is the TPE as in Hyperopt.
number_of_initial_random_step=20,
),
validation_splitter=ValidationSplitter(validation_size=0.20),
scoring_callback=ScoringCallback(accuracy_score, higher_score_is_better=True),
n_trials=40,
epochs=1, # Could be higher if only TF models were used.
hyperparams_repository=HyperparamsOnDiskRepository(cache_folder=neuraxle_dashboard),
refit_best_trial=True,
continue_loop_on_error=False
)
# Load data, and launch AutoML loop!
X_train, y_train, X_test, y_test = generate_classification_data()
auto_ml = auto_ml.fit(X_train, y_train)
# Get the model from the best trial, and make predictions using predict, as per the `refit_best_trial=True` argument to AutoML.
y_pred = auto_ml.predict(X_test)
accuracy = accuracy_score(y_true=y_test, y_pred=y_pred)
print("Test accuracy score:", accuracy)

Why Neuraxle ?
--------------
Most research projects don't ever get to production. However, you want
your project to be production-ready and already adaptable (clean) by the
time you finish it. You also want things to be simple so that you can
get started quickly. Read more about `the why of Neuraxle here. `_

For **technical questions**, please post them on
`StackOverflow `__
using the ``neuraxle`` tag. The StackOverflow question will automatically
be posted in `Neuraxio's Slack
workspace `__ and our `Gitter `__ in the #Neuraxle channel.
For **suggestions, feature requests, and error reports**, please
open an `issue `__.
For **contributors**, we recommend using the PyCharm code editor and to
let it manage the virtual environment, with the default code
auto-formatter, and using pytest as a test runner. To contribute, first
fork the project, then do your changes, and then open a pull request in
the main repository. Please make your pull request(s) editable, such as
for us to add you to the list of contributors if you didn't add the
entry, for example. Ensure that all tests run before opening a pull
request. You'll also agree that your contributions will be licensed
