\## Executive Summary

Recent advancements in machine learning have led to systems that significantly influence personal and business decisions. However, these systems often lack transparency, leaving users uncertain about how to achieve their desired outcomes when faced with unfavorable decisions. Traditionally, addressing this issue has required costly human oversight, particularly in designing a cost function to identify the most effective actions to take.

This research introduces a novel method called "Data-Driven Action Recourse" (DDAR). This approach allows for the identification of possible actions a user can take without needing expensive human intervention. The core idea of DDAR is to leverage historical user data to model likely behaviors and outcomes. By analyzing this data, DDAR identifies paths that users have previously taken which led to favorable results. This enables the system to recommend actions that are both feasible and cost-effective.

In practice, DDAR builds a dynamic model based on past user trajectories. It analyzes these trajectories to find those that align with the user’s desired outcomes. The results from experimental simulations indicate that DDAR can recommend more plausible and lower-cost actions compared to existing methods that rely on human supervision.

The implications of this research are significant for various industries where automated decision-making systems are prevalent. Organizations could implement DDAR to enhance user satisfaction by providing clearer pathways to success without incurring the high costs of manual oversight. This could be particularly beneficial in sectors like finance, healthcare, and customer service, where decision outcomes heavily impact user experiences.

While the findings are promising, they stem from controlled experiments rather than real-world applications. This suggests that further testing in actual operational environments is necessary to validate the effectiveness of DDAR in practice. However, the foundational concept offers a compelling direction for future developments in decision-support systems.

\## Academic Abstract

As machine learning systems make increasingly greater decisions about people's lives, it is critical to provide users with actionable recourse about how they can achieve their desired outcomes. This problem is currently tackled by relying on expensive human supervision which involves hand-designing a cost function before searching for low-cost actions that achieve the desired outcome. In this paper, we propose \textit{``Data-Driven Action Recourse"} (DDAR), the first approach for providing action recourse without requiring costly supervision from humans about action costs. We build upon the notion that highly likely trajectories in the historical user data should be associated with lower costs. With this, DDAR first builds a dynamics model of historical user trajectories. Under this model, it then searches for trajectories that achieve the desired outcome. In experiments, we find that this simple approach recommends plausible action recourse without requiring human supervision, achieving lower action costs than the existing approaches.
