Do you want to work on this baseline?

🌻 Check everything about the Summer of Reproducibility on flower.dev/summer

All available baselines are listed in the Summer of Reproducibility Dashboard and also in the GitHub Issues with the summer-of-reproducibility label. The content is the same.

📝 It is advised to complete these steps before your start working on your code. But if you can't wait to implement your baseline with Flower (we totally understand it 😄), please ensure you follow the steps on how to contribute a new baseline.

What follows are the steps 1 & 2 in the Summer of Reproducibility instructions.

1. Join the Summer of Reproducibility program

• [x] Join the Flower Slack and say "hi! 👋" in the channel #summer-of-reproducibility.
• [x] Pick a baseline from our curated list <---------------------------------------- [you are doing this now]

  2. Define the scope of your contribution

• [x] What are you going to reproduce? Add a comment to your issue and tell us about your plan regarding this baseline: what experiments from the paper are you reproducing?, for which datasets ? the more details you provide us with the better !

• [x] Check if you are eligible for a reward.

  As we have to comply with US/EU regulations, we have checked that individual contributors based on these countries or territories are eligible: Australia, Austria, Belgium, Bulgaria, Canada, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Gibraltar, Greece, Hong Kong SAR China, Hungary, India, Ireland, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, United Arab emirates, United Kingdom United States.

  If where you are based is not on the list, please send us an email (summer@flower.dev) letting us know a bit about yourself (where are you currently based?, are you a university student? do you work at a public institution?). Please tell us the baselines you are interested in implementing (i.e. tell us your GitHub issue if you have crated one). We will reach back to you.

• [x] We will discuss with you about your contribution plan, if it sounds like a substantial enough contribution according to the Summer of Reproducibility rules (check our website flower.dev/summer), you'll get the OK from us to start working on your baseline!

What happens next?

• [x] This item will be moved to the In Progress stage by a member of the Flower Team.

• [ ] Follow the instructions for creating a new baseline which will guide you through the process step-by-step.

Is something wrong or not clear ?

• Ask a question directly in your issue.
• Reach out to us via the Flower Slack and ask your question in the #summer-of-reproducibility channel
• Check all the details (including FAQ) in the Summer of Reproducibility website: flower.dev/summer

Hi Javier,

I am keen to implement and reproduce this work for Flower. Specifically, I want to focus on reproducing Table 3, rows 2 and 3, for all columns. That is, I will test my implementation using logistic regression task on the EMNIST dataset against FedAvg baseline.

Thanks, Aashish Kolluri

Hi Aashish (@aashishkolluri ), this looks like a good plan for SCAFFOLD! Am I understanding it correctly that when you say "rows 2 and 3" for Table 3 you mean the block of rows for FedAvg and for SCAFFOLD in the table? Also, could you confirm were you are based is on the list of countries/territories that are eligible? You can find the list afterthe second point in Step 2 (you don't have to say where you are, just confirming that you are eligible is good enough)

[aashishkolluri]

Yes you are right about FedAvg and SCAFFOLD. I am based on the list of countries.

[jafermarq]

Perfect! I have ✅ all the points in Step 1 & 2 since they are now completed. I have also added you as the assignee to this issue and labeled it as In Progress. You can find info on how to start with the code by following the link in the what happens next? section after Step 2 in the description of this issue. If you have some doubts or questions please preferably use our #questions or #summer-of-reproducibility Slack channel.

Looking forward to seeing SCAFFOLD in action!

Hi @aashishkolluri ! This is just a gentle reminder that the Flower Summer of Reproducibility is ending at the end of the month. With just a little more than 3 weeks to go, we are excited to see quite a few baselines well ahead in the process with their respective PRs close to ready. If your PR is already on the list, great !! Please make sure the PR is linked to this issue (you just need to copy the URL of this issue somewhere in the main message of your PR). Ping me when you'd like me to take a look.

Also, make sure you keep an eye:eyes: on the #summer-of-reproducibility channel in the Flower Slack. I’ll announce very soon a new (the third!) round of 1:1 ask-me-anything sessions to help Summer of Reproducibility contributors like yourself to meet the deadline. Please consider booking a time slot if you want to chat with me about your baseline, potential issues you have making your code run, how to open a PR, doubts about what to include in your readme, how to use Hydra configs more effective, etc … all questions are welcome!!

Hi @jafermarq, can I take this one up? I've aldready implemented SCAFFOLD - see here. So I just need to make few changes to make it compatible with Flower.

I am currently implementing SCAFFOLD as a baseline here: https://github.com/wittenator/flower/tree/rework_fedprox_baseline/baselines/scaffold
