promnná

Promnná is a theoretical construct in formal modeling that denotes a variable whose value depends on context rather than being fixed by a single rule. The term is used chiefly in discussions of context-aware computation, dynamic systems, and linguistics modeling. In formal terms, a promnná is a variable V that, for each time t, takes values from a set Val(V) according to a promnnic function f that consumes a context vector C_t, the variable's history H_t, and possibly external inputs E_t. The value V_t is thus V_t = f(C_t, H_t, E_t).

Characteristics include context sensitivity, time dependence, potential non-determinism, and modularity allowing composition with other promnná. Variants encompass crisp promnná (deterministic mapping) and probabilistic promnná (stochastic mapping with a distribution conditioned on context).

Applications of promnná appear in modeling mood and stance in social simulations, discourse-level pronoun resolution, adaptive control in robotics, and dynamic preference modeling in recommender systems. The concept provides a flexible way to encode how context and history influence variable states in complex systems.

Origin and status of usage are that promnná is a neologism used in select theoretical discussions and is not universally standardized; definitions and formalizations vary across authors and domains. As a result, practical implementations tend to be bespoke, aligned with the specific modeling framework or application area.
