We have open sourced the toolkit behind www.ramp.studio and all the starting kits. You can use rampwf to build your own predictive workflows, organize workflow building and optimization within an internal data science team, and submit the kit to us if you want to run a code submission data challenge. https://www.ramp.studio https://github.com/paris-saclay-cds/ramp-workflow https://github.com/ramp-kits https://ramp-studio.slack.com

We decided to turn them into a
tool for
1. Collaborative prototyping
2. Teaching aid
3. Data science team management

10. 10
You can
1. Participate in upcoming RAMPs
2. Use RAMP in teaching or training

11. 11
Setting up the RAMP
is was
long and hard.

12. 12
Separate workflow building
and workflow optimization

13. 13
Before solving the problem,
set it up
(even put it into production)

14. • toolkit: https://github.com/paris-saclay-cds/ramp-workflow
• for designing workflows
• set of ready-made metrics, workflows, CV schemes, data readers
• unique command-line test script
• examples: https://github.com/ramp-kits
• a zoo of problems, experiments, workflows
• (at least) one initial solution

• Keep your different
submissions in a simple
file structure
• Communicate them on git
• Execute them also from
the notebook

You can
1. Use rampwf for your own workflows
2. Use rampwf to organize workflow
building and optimization in an internal
data science team
3. Submit it to us if you want to run a data
challenge
