Webb29 juni 2024 · The notation f(x) means that you take the function f, apply it to the input variable x, and receive some output. f(f(x)), then, means that you take the output of f(x) and apply the function f to it. Note that solving f(0) is very different to solving f(x) = 0. If the former case, you're setting the input to zero, and finding what the output is. WebbA lens that has a maximum aperture of f/1.4 or f/1.8 is considered to be a “fast” lens, because it can pass through more light than, for example, a lens with a “slow” maximum aperture of f/4.0. That’s why lenses with large apertures usually cost more. Do I need 85mm if I have 50mm? The head and shoulders shot is where the 85mm shines.

Therefore, if f ∈ Θ ( g) that means that f is in that set, i.e. it is bounded below and above by g.

"Webb10 apr. 2024 · The geometric mean (G-mean) is the root of the product of class-wise sensitivity. This measure tries to maximize the accuracy on each of the classes while keeping these accuracies balanced. For binary classification G-mean is the squared root of the product of the sensitivity and specificity. " - Tn 0.5* mean f g +mean f g
