Computational materials engineering has evolved into a data-intensive discipline where high-throughput computation, representation learning, and autonomous discovery systems enable systematic exploration of vast chemical spaces. Central to this evolution is the recognition that model priors—inductive biases, architectural assumptions, and regularization structures embedded in machine learning pipelines—actively reshape the effective searchable materials space rather than merely operating within it. Despite advances in materials informatics, graph neural networks, and closed-loop experimentation, the systemic influence of these priors on screening frontiers remains conceptually underexplored. This article presents the Priors-Adaptive Frontier Reshaping (PAFR) Framework, an original systems-level conceptualization that formalizes how priors modulate data-to-discovery pipelines through layered interactions between representation spaces, inference dynamics, and feedback loops. By integrating insights from multimodal datasets, uncertainty quantification, and simulation–experiment coupling, the framework elucidates computational workflow dynamics and epistemic risk structures that govern algorithmic screening efficiency. The PAFR Framework offers interpretive guidance for designing more robust infrastructures in materials discovery, highlighting trade-offs in prior selection, search space expansion, and steering logics.

Computational materials engineering has evolved into a data-intensive ecosystem in which high-throughput screening, machine learning surrogates, and autonomous discovery pipelines increasingly dictate the pace and direction of materials innovation. Within this paradigm, the spatial and compositional density of available computational data emerges as a previously under-examined source of systematic bias. Uneven sampling—whether arising from historical focus on well-studied chemical spaces, computational cost gradients, or architectural preferences of representation-learning models—creates “data deserts” that skew downstream inference, limit generalization of generative architectures, and constrain the reach of closed-loop optimization. The present conceptual analysis identifies data density as an epistemic rather than merely statistical bias and introduces the Density-Compensated Epistemic Exploration Framework (DCEF) as an interpretive infrastructure that reframes discovery pipelines through explicit density mapping, bias quantification, and adaptive steering logics. By integrating representation-learning dynamics with uncertainty propagation and feedback-driven re-sampling, the DCEF offers a systems-level lens for diagnosing and mitigating discovery bias without invoking empirical validation or performance metrics. Its implications extend to the design of next-generation materials data infrastructures, the governance of foundation models for science, and the epistemic transparency of simulation–experiment coupling.
