# Glossary ## Competition A structured, (often) time-bound, incentive-driven challenge where participants (typically data scientists) compete to solve a specific problem or achieve a defined objective using data, algorithms, or machine learning models. ## Crunch A period during which the leaderboard can be updated and compute quotas can be refreshed. This period usually lasts for a week, but it can be arbitrary. {% hint style="info" %} Crunch is the technical term. It is also used by marketers to refer to a [Competition](#competition). {% endhint %} ## Submission Phase Part of the competition while submission is allowed. The data does not change and the quota is regularly reset. It is also known as the public leaderboard. ## Out-of-Sample Phase Part of the competition while scoring is happening on an out-of-sample phase. The data does change regularly, and no modification is allowed to your code or selection. It is also known as the private leaderboard. ## Submission Similar to a Git commit, a submission represents a frozen version of a user's code. Once on the platform, no file can be updated and the message cannot be changed. ## Run Similar to GitHub Actions, a run is when a user's code is executed in the cloud environment. The environment is heavily restricted. The user's code must follow the [Code Interface](/competitions/participate/code-interface.md) in order to run properly. ## Prediction A prediction is the output of a [Run](#run). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
