Derivative of conditional expectation
http://www.columbia.edu/~ltg2111/resources/mostlyharmlesslecturenotes.pdf WebThe derivatives of a function (or curve) tell you whether changes occur and in which direction they occur. With the derivative ICE plot, it is easy to spot ranges of feature values where the black box predictions change for (at least some) instances.

Webin G. One nal note on conditional expectation is that we can have examples like E[Xjthe rst die is 4] = 7:5 or E[Xjthe rst die is greater than 2] = 8 where the expectation of Xgiven some other event is a constant; in fact, it is a value taken by E[XjG]. Proposition 2.18. The following are properties of conditional expectation. If Y is G ...
Webto obtain representations for conditional expectations and their derivatives (with respect to the underlying) in a jump-diffusion setting. The representations we derive are expressed in terms of regular expectations without conditioning but involving a Heaviside step function and some weights. We apply the developed theory to the WebMar 3, 2024 · We compute the derivatives of g, h: g ′ ( b) = f ′ ( b) { b [ F ( b) − F ( a)] − ∫ a b x f ( x) d x } + f ( b) { F ( b) − F ( a) + b f ( b) − b f ( b) } = f ′ ( b) { b [ F ( b) − F ( a)] − ∫ a b x f ( x) d x } + f ( b) [ F ( b) − F ( a)]
Weba derivative is basically just the change. This won’t be exact given the discrete nature and the fact that derivatives are relevant for small changes and continuous variables, but it’ll … WebNov 9, 2024 · STA 711 Conditional Expectation R L Wolpert When λ ≪ µ (so λa = λ and λs = 0) the Radon-Nikodym derivative is often denoted Y = dλ dµ = λ(dω) µ(dω), and extends the idea of \density" from densities with respect to Lebesgue measure to those with respect to an arbitrary \reference" (or \base" or \dominating") measure µ.

Partial dependence plots show the dependence between the target function [2] and a set of features of interest, marginalizing over the values of all other features (the complement features).
