Project description

Compose is a machine learning tool for automated prediction engineering. It allows you to structure prediction problems and generate labels for supervised learning. An end user defines an outcome of interest by writing a labeling function, then runs a search to automatically extract training examples from historical data. Its result is then provided to Featuretools for automated feature engineering and subsequently to EvalML for automated machine learning. The workflow of an applied machine learning engineer then becomes:

By automating the early stage of the machine learning pipeline, our end user can easily define a task and solve it. See the documentation for more information.

Install

Compose is available on PyPI and Conda-forge for Python 3.6 or later.

pip

To install from PyPI, run the command:

pip install composeml

conda

To install from Conda-forge, run the command:

conda install -c conda-forge composeml

Example

Will a customer spend more than 300 in the next hour of transactions?

In this example, we automatically generate new training examples from a historical dataset of transactions.

import composeml as cp
df = cp.demos.load_transactions()
df = df[df.columns[:7]]
df.head()

First, we represent the prediction problem with a labeling function and a label maker.

def total_spent(ds):
    return ds['amount'].sum()

label_maker = cp.LabelMaker(
    target_entity="customer_id",
    time_index="transaction_time",
    labeling_function=total_spent,
    window_size="1h",
)

Then, we run a search to automatically generate the training examples.

label_times = label_maker.search(
    df.sort_values('transaction_time'),
    num_examples_per_instance=2,
    minimum_data='2014-01-01',
    drop_empty=False,
    verbose=False,
)

label_times = label_times.threshold(300)
label_times.head()

We now have labels that are ready to use in Featuretools to generate features.

Support

The Innovation Labs open source community is happy to provide support to users of Compose. Project support can be found in three places depending on the type of question:

  1. For usage questions, use Stack Overflow with the composeml tag.
  2. For bugs, issues, or feature requests start a Github issue.
  3. For discussion regarding development on the core library, use Slack.
