statereducing
State reducing is the act of decreasing the amount of information necessary to describe the state of a system. In practice, it means replacing a high-dimensional or detailed state with a lower-dimensional, coarse-grained representation. The term appears across disciplines, where the precise meaning depends on the domain.
In quantum mechanics, state reduction (also called wavefunction collapse) refers to the non-unitary update of a
In control theory and dynamical systems, state reduction often means model order reduction: constructing a lower-order
In stochastic processes and Markov modeling, state reduction results from lumping or aggregation: combining several microstates
Across usages, state reducing emphasizes simplification at the cost of some loss of detail. The appropriate
