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. 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. chop blox fruits https://smediamoo.com

Webb27 maj 2024 · In this case Θ ( g ( x)) is the set of functions that are asymptotically bounded below and above by g. Therefore, if f ∈ Θ ( g) that means that f is in that set, i.e. it is bounded below and above by g.
