Training and AutoML Summit Recap – Part 2

Training and AutoML Summit Recap Part 2

Did you miss the AutoML and Training working groups’ summit back in July? If you did, all the talks from the event have been uploaded to YouTube.  

Reminder, if you attended the Summit, the organizers kindly ask you to complete this survey. Your answers will help the Kubeflow contributors! 

This is part two in the blog series where we’ll give you an executive summary of the first batch of the day’s talks. Missed part one? Here it is.

If you are new to Kubeflow and AutoML

The Kubeflow project is organized into working groups with associated GitHub repositories, that focus on specific pieces of the ML platform. These include:

  • AutoML
  • Deployment
  • Manifests
  • Notebooks
  • Pipelines
  • Serving
  • Training

As the name suggests, the goal of automated machine learning (AutoML) is to automate as many of the tasks associated with machine learning as possible. In a perfect world, AutoML allows non-data science experts to make use of machine learning models and techniques and apply them to problems. Aside from making machine learning more accessible to non-experts, AutoML also has the advantage of creating solutions that are easier to understand, can be designed quickly and are pre-optimized vs those that are “hand-rolled” from scratch.

The tasks AutoML seeks to dramatically simplify include:

  • Data pre-processing
  • Feature engineering
  • Feature extraction
  • Feature selection
  • Algorithm selection
  • Hyperparameter tuning

As you can imagine, AutoML is “kind of a big deal” in the context of making Kubeflow accessible to experts and non-experts alike. This is where having a dedicated AutoML working group comes in. The working group’s chairs include:

  • Andrey Velichkevich, Cisco
  • Ce Gao, Caicloud
  • Johnu George, Nutanix

The co-organizers of the Summit were the folks from the Training working group. This group covers developing, deploying, and operating training jobs on Kubeflow. The working group’s chairs include:

  • Ce Gao, Caicloud
  • Johnu George, Nutanix
  • Yuan Tang, Ant Group

Ok, let’s look at a few previews of talks from the last half of the summit.
