Explainable AI interfaces in cloud‑deployed portfolio optimization systems

Abstract

As artificial intelligence (AI) increasingly drives decision-making in finance, ensuring transparency and trust becomes essential, particularly in high-stakes applications like portfolio optimization. This paper explores the integration of Explainable AI (XAI) interfaces within cloud-deployed portfolio optimization systems, aiming to bridge the gap between advanced AI models and financial professionals. We outline a cloud-native architecture that embeds explainability into each stage of the portfolio optimization lifecycle, from data ingestion to user interaction. Various XAI methods, including feature attribution and model-agnostic explanations, are examined in the context of financial decision-making. We present design considerations for building user-facing interfaces that make model decisions interpretable and actionable. A case study illustrates how such interfaces can enhance user trust and improve portfolio strategy validation. Finally, we discuss technical, regulatory, and usability challenges, and propose future research directions for deploying responsible AI in cloud-based financial systems.
