DAY-2 (Wednesday, March 29)

Isabel Cordero-Carrión

• Visualization of short movie before session: Patterns - Signals from the Universe
• Send by email (isabel.cordero@uv.es) until the end of Thursday March 30th your script for a 5 minutes long monologue / video. You are not requested to do the monologue or the video, JUST THE SCRIPT. Don't forget to include authors of the script. LAST TIME COMMENT: All the participants are working very hard in the hackaton competition, so I am going to extend the period for deliver your works until the end of the school. I will read all the proposals carefully during the weekend, and give a little of input back.

The top 3 selections of the submitted works for the outreach activity during Isabel Cordero Carrión's lecture are: Amlan Nanda, Evdokia Koursoumpa and Vladimir Sivtsov. Congratulations!

Nikolaos Stergioulas

• Surrogate models

DAY-3 (Thursday, March 30)

Hackathon on Kaggle!

• We will take a screenshot of the private leaderboard and post it here at 12:45pm local time on Friday, March 31.
• The top teams will then have the opportunity to briefly present their network archicture (either in person or remotely).
• The hackathon will be ongoing for another week, to allow participants to spend more time to improve their results!

DAY-4 (Friday, March 31)

Natalia Korsakova

• Machine Learning for Gravitational Wave Parameter Estimation
