An online system dynamically determines time periods during which interaction data points are collected for application states being tested as part of an application state experiment. The online system collects interaction data points that occurred after a time when instructions were transmitted to apply the first application state and labels those with a state label corresponding to the first application state. When the online system detects that an interaction data minimum has been met, the online system transmits instructions to the client devices to present a user interface in accordance with a second application state. The online system applies a transition period between when the second set of instructions are transmitted and when the online system starts labeling interaction data points with a state label for the second application state. After the transition period, the online system labels interaction data points with state labels for the second application state.

A system validates code ownership of software components identified in a build process. The system receives a pull request identifying a set of software components. The system analyzes code ownership of each software component using machine learning. The system provides features describing the software components as input to a machine learning model. The system determines based on the output of the machine learning model, whether the code ownership of the software component can be determined accurately. If the system determines that a software component identified by the pull request cannot be determined with high accuracy, the system may block the pull request or send a message indicating that the code ownership of a software component cannot be determined accurately.
