This high-level diagram explains the feedback loop for Horizon. First, we preprocess some data that the existing system has logged. Then, we train a model and analyze the counterfactual policy results in an offline setting. Finally, we deploy the model to a group of people and measure the true policy. The data from the new model feeds back into the next iteration, and most teams deploy a new model daily.
