The Cosmostatistics Initiative

The Cosmostatistics Initiative (COIN) is a worldwide  endeavour aimed to foster interdisciplinary collaborations to solve data-driven scientific challenges.

The group is co-lead by Rafael S. de Souza (SHAO, China), Alberto Krone-Martins (UCI, USA) and Emille E. O. Ishida (CNRS, France).

Researchers willing to join are welcome to contact any of the chairs!

COIN Focus #4 - SPICY

The SPICY project was one of the results from COIN Residence Program #6 (CRP6), which took place in Chamonix, France, August/2019. It consisted of a catalog of young stellar objects (YSO) automatically identified using machine learning.

Since then, the project expanded and evolved, enabling the detection of interesting new features of our Milk Way structure. More recently, the team lead by Michael A. Kuhn spectroscopically confirmed the nature of a sub-sample of the SPICY objects -- thus providing further evidence of its low contamination.

Now we look into the future. In order to prepare tools and methodologies for the arrival of large and complex data sets (e.g. the Vera Rubin Observatory), we will bring together members from the COIN network to this Focus meeting.

Since the 17th century, Paris has been one of Europe's major centres of finance, diplomacy, commerce, fashion, science and the arts. Paris is especially known for its museums and architectural landmarks: the Louvre was among most visited art museums in the world in 2019, with 9.6 million visitors. The historical district along the Seine in the city centre is classified as a UNESCO Heritage Site, and popular landmarks in the city centre included the Cathedral of Notre Dame de Paris, now closed for renovation after the 15 April 2019 fire. Other popular tourist sites include the Gothic royal chapel of Sainte-Chapelle, both on the Île de la Cité; the Eiffel Tower, constructed for the Paris Universal Exposition of 1889; the Grand Palais and Petit Palais, built for the Paris Universal Exposition of 1900; the Arc de Triomphe on the Champs-Élysées, and the Basilica of Sacré-Coeur on the hill of Montmartre.

The city provides a perfect atmosphere for the friendly and comfortable environment required for a COIN meeting.


Code of Conduct

COIN is composed of members from around the globe with a diverse set of skills, personalities, and experiences. This is one of the characteristics which makes it unique and fruitful.

We require participants to follow these guidelines which help steer our interactions and strive to keep COIN meetings an enlightening experience for all members involved.

The official language of COIN Focus #4 is English.


COIN Focus #4 - SPICY will be a harassment-free environment for everyone, regardless of gender, sexual orientation, disability, physical appearance, body size, race, nationality or religion.

Please bring any issues to the confidential attention of the workshop organizers.


Be receptive to constructive comment and criticism, as the experiences and skill sets of other members contribute to the whole of our efforts.

Be thoughtful when addressing the efforts of others, keeping in mind that often times the labour was completed simply for the good of the group.

Be good and respectful to each other.

Given the informal nature of the program, be perceptive about eventual help needed in the organization and maintenance of the household tasks. Remember that there is no room service or catering. Keeping things clean and organized is up to the group itself.

COIN Focus #4 is a strictly non-smoking event. Smoking is not allowed anywhere inside the venue.

Participants sharing a room should pay attention to tidiness, personal hygiene, sleeping hours and noise. In the common areas, there is no time limit and you can keep working through the night, if you wish to.
Publication and authorship:

The mere participation in the meeting does not guarantee authorship in produced papers or other products.

Publications developed during the COIN meetings are lead by volunteer participants who commit to the implementation of all stages of the project during and after the meeting.

All participants who contribute to development of a project will be included in the author list. The order of the authors is decided by the project leader, in common agreement with the chairs,  once the paper is finalized.
