Machine learning for healthcare just got a whole lot easier

The healthcare.ai packages are designed to streamline healthcare machine learning. They do this by including functionality specific to healthcare, as well as simplifying the workflow of creating and deploying models.

Learn more about machine learning via the healthcare.ai community by reading and subscribing to our weekly blogs, viewing our weekly YouTube live event broadcasts, and engaging our data science team with questions and answers via email or live events.

Everything you need to get started

What can I do with healthcare.ai?

  • Create and compare models based on your data.
  • Save and deploy a model.
  • Perform risk-adjusted comparisons.
  • Do trend analysis following Nelson rules.
  • Improve sparse data via longitudinal imputation.
  • Fill in missing data via imputation.
  • Deploy a model to produce daily predictions.
  • Write predictions back to a database.
  • Learn what factors drive each prediction.

How is it tailored to healthcare?

  • Longitudinal machine learning via mixed models.
  • Longitudinal imputation.
  • Risk-adjusted comparisons.

Collaborate!

Our goal with this project is to expedite adoption of ML in healthcare by building pragmatic world class tools to help anyone with access to healthcare data.

You can help in many ways:

  • Try out the packages and let us know what needs improvement!
  • Check out our Github repos

How do I get started?

Healthcare.ai is available in packages for both R and Python, two of the most common languages used by data scientists. If you don’t previous experience with either language, we recommend the R package as it currently has more features and R is more newbie-friendly.

Let's do this!

Access documentation, installation instructions, feature references, as well as hints and tips.

How does healtcare.ai focus on healtcare?
Both packages differ from other machine learning packages in that they focus on data issues specific to healthcare. This means that we pay attention to longitudinal questions, offer an easy way to do risk-adjusted comparisons, and provide easy connections and deployment to databases.
Who is healthcare.ai designer for?
While data scientists in healthcare will likely find these packages valuable, the audience healthcare.ai targets are those analysts, BI developers, and SQL developers that would love to create appropriate and accurate models with healthcare data.

A few weeks ago, our blog featured a post about k-means clustering, an unsupervised machine learning method. We use unsupervised methods when we don’t have an explicit idea of what patterns exist in a dataset. Clustering can help us surface insights about groups that exist in the data that we may not know about. To separate data into clusters, k-means first needs to calculate the distance between each data point. That distance is used to help define the “similarity” between two points and is normally calculated using some continuous technique…

The two main algorithms used for binary classification in healthcareai are logistic regression with a Lasso penalty (from now on, simply the Lasso) and random forests.  In this post, we’ll visually explore the behavior of the Lasso and random forest models by working with some artificial 2-dimensional datasets to help build intuition about how the algorithms work and on what type of datasets each algorithm can perform well on. All the Lasso and random forest models plotted below were built using the healthcareai R package (the plots were built in…

Why did Health Catalyst open source this?

We believe that everyone benefits when healthcare is made more efficient and outcomes are improved. Machine learning is surprisingly still fairly new to healthcare and we want to quickly take healthcare down the machine learning adoption path. We believe that making helpful, simple tools widely available is one small way to help healthcare organizations transform their data into actionable insight that can be used to improve outcomes.
