Transcript of Involving other communities through challenges and cooperation

Although the
challange on Kaggle has finished, the dataset is still available online: http://higgsml.lal.in2p3.fr
LHCb have just released their own challenge to ask people to identify a rare decay phenomenon:
ATLAS and CMS are looking at another challenge.

Instructions for downloading
can be found on the website:

Zooniverse is a collection of web-based citizen science projects that use the efforts of volunteers to help researchers deal with the flood of data that confronts them.

The ATLAS@home project allows
volunteers to run simulations
of collisions in the ATLAS detector using the idle processing time of their home computers.
For the first year the community consisted of software fans, who were attracted by the technical challenge and contributed to the debugging via message boards.
With the start of LHC, the number of people attracted for outreach reasons is growing.

Rewards are for different contributions:
- for being in the top Nth percentage of the users contributing the most Recent Average Credit (RAC).
The top 1% get a top quark.
- for perseverance.
After 180 days, they get a tau neutrino.
- years of involvement.
After 5 years, they get a Higgs.

Q: What are they classifying?
A: "Lines that seem to sprout from a common point that is NOT the center. These are called "Off-center vertexes" (OCVs)."

CERN Ask Me Anything (AMA) on Reddit, June 2015
To benefit from the knowledge of the machine learning community and to engage the public with the type of analysis work required to discover the Higgs.
The challenge ran from May to September 2014 on the Kaggle platform.
The signal used was Higgs to two tau particles, simulated by the ATLAS experiment.
Greater than one million users worldwide!
With 20 projects and 60 papers.
Kaggle’s most popular challenge event at the time!
Tianqi Chen and Tong He received the "HEP meets ML" award

The dataset used in the challenge will remain on CERN Open Data Portal with a citeable d.o.i.:
Contains ~800k events.

The ATLAS collaboration has recently setup three projects targeting citizen science or specific communities.

The significance of the dataset increased by 20% with respect to the traditional HEP tool (TMVA).
It was a very fruitful collaboration established with the machine learning community.
New techniques and new software came from the collaboration.

No knowledge of particle physics is required, but for those interested in the physics processes simulated in ATLAS@Home as well as the ATLAS experiment itself visit our public page.
