Example: "To solve this complex problem, we need an exact knowledge of the underlying principles involved."
Alternatives: "a precise understanding" or "a clear comprehension."

SMC allows to avoid the need of an exact knowledge of the system parameters and offers many desirable properties, such as good performance against no modelled dynamics, insensitivity to parameter variations, and an excellent external disturbance rejection.
Or one might hope to inform later deliberations about history, as Thucydides did: "[If my work] be judged useful by those inquirers who desire an exact knowledge of the past as an aid to the interpretation of the future, which in the course of human things must resemble if it does not reflect it, I shall be content".

However, from a practical point of view, the exact knowledge of a t (θ k ) can not be available.
Although an exact LNLR computation required exact knowledge of the linear and nonlinear system components to compute the respective signal components, the LNLR can be estimated using the echo estimate (hat {y} k)) obtained by a converged long adaptive linear filter and the resulting error signal (e k)=y k -hat {y}(k)).
