The Comet Panel Contest invites data scientists globally to contribute to the largest machine learning visualization gallery by submitting their unique Comet Panels. Participants have the opportunity to win a free t-shirt or donate to their favorite charity if they are among the first 200 to submit. The process involves logging into comet.ml, creating or altering a Comet Panel within a public project, ensuring the panel is original, useful, and credits any foundational work, and making it publicly accessible. Participants are encouraged to provide a detailed description, options, and a thumbnail for their panels, verify public access via an incognito window, and share a link to their public panel. The contest promotes collaboration and innovation in the machine learning community by expanding the visualization resources available to professionals worldwide.
