Symbol f

dx(t)dt=−[1τ+f(x(t),I(t),t,θ)]⊙x(t)+f(x(t),I(t),t,θ)⊙A,\frac{d\mathbf{x}(t)}{dt} = -\left[\frac{1}{\tau} + f(\mathbf{x}(t),\mathbf{I}(t),t,\theta)\right]\odot \mathbf{x}(t) + f(\mathbf{x}(t),\mathbf{I}(t),t,\theta)\odot A ,
ff

What this part means

f occurs above the fraction bar. The numerator is divided by the entire denominator below it.

Its job in the formula

The passage around this formula

…tested. The Vorbach result is a property of a model class : an LTC network, described by the ordinary differential equation the paper reproduces as dx(t)dt=−[1τ+f(x(t),I(t),t,θ)]⊙x(t)+f(x(t),I(t),t,θ)⊙A\frac{d\mathbf{x}(t)}{dt} = -\left[\frac{1}{\tau} + f(\mathbf{x}(t),\mathbf{I}(t),t,\theta)\right]\odot \mathbf{x}(t) + f(\mathbf{x}(t),\mathbf{I}(t),t,\theta)\odot A . reduces to a DCM whenever its learned function f satisfies three stated analytic conditions [ 1 , 2 ] . That is a real theorem about the architecture’s dynamical form, established independently of this drone task, and nothing in this article disputes it. What it does not supply, on its own, is a certificate that the specific f this paper’s…
