Capacityn
Capacityn is a term used in theory and applied disciplines to denote a capacity measure that depends on an integer parameter n. In practice, capacityn is not a single, universal quantity; its precise definition varies by context but the common thread is that it represents the maximum level of performance, throughput, or information that a system can sustain when it has n units, channels, neurons, or other resources.
In information theory and communications, capacityn often refers to the capacity of a system with n parallel
In queueing theory and networks, capacityn denotes the largest stable arrival rate that can be serviced by
In machine learning and statistical modeling, capacityn may denote the representational capacity of a model with
General properties: capacityn is typically nondecreasing in n; under mild conditions it grows, sometimes linearly with
Computation and analysis: capacityn is usually estimated via theoretical bounds, asymptotic analysis, or empirical simulations; exact
