A note about the Journal Club format:

  1. There is no speaker at Journal Club.

  2. There is NO speaker at Journal Club.

  3. We split into small groups of 6 people and discuss the papers. For the first hour the groups are random to make sure everyone is on the same page. Afterwards we split into blog/paper/code groups to go deeper.

  4. Volunteers sometimes seed the discussion by guiding through the paper highlights for 5 mins. You are very welcome to volunteer in the comments.

  5. Reading the materials in advance is really helpful. If you don't have time, please come anyway. We need this group to learn together.

Thanks to our sponsors
