In the evolving landscape of computational and data-driven materials engineering, the integration of machine learning and high-throughput methodologies has transformed traditional materials discovery into sophisticated algorithmic processes. This shift emphasizes the need to reframe materials selection algorithms as discovery recommendation systems, where predictive models serve not merely as classifiers but as dynamic recommenders guiding exploration across vast chemical spaces. A conceptual gap persists in how these systems handle the interplay between representation learning, uncertainty quantification, and closed-loop feedback, often leading to suboptimal navigation of multimodal datasets. To address this, we introduce the Adaptive Discovery Recommendation Architecture (ADRA), a novel framework that conceptualizes materials selection as a recommendation engine optimized for epistemic steering in inverse design workflows. ADRA incorporates layered computational logics that balance representation fidelity with inference adaptability, enabling seamless coupling of simulation and experimental data streams. By reframing algorithms through recommendation paradigms, ADRA highlights infrastructure trade-offs in scalability and interpretability, fostering more robust discovery pipelines. Implications extend to materials informatics ecosystems, enhancing autonomous systems in high-throughput computation and foundation models for science. This conceptual reframing underscores the potential for recommendation-based steering to mitigate epistemic risks, ultimately advancing data-driven innovation in materials engineering.
