My guess is that they meant to ask a different question. The hint is that they use G for the set, which suggests they may be thinking of groups. I think they meant to specify that where those two elements are considered as Abelian groups under addition.

WebWe propose regularization methods for linear models based on the Lq-likelihood, which is a generalization of the log-likelihood using a power function. Regularization methods are popular for the estimation in the normal linear model. However, heavy-tailed errors are also important in statistics and machine learning. We assume q-normal distributions as the … WebApr 21, 2010 · Apr 20, 2010. #1. Hi. I am trying to show that for f belonging to L^2 (-pi;pi) the integral that defines the complex Fourier Coefficients is well defined. In other words what I need to show is that. int_from -pi to pi ( f (x)*exp (-i*k*x) dx) < infinity (limited) I was thinking that since f belongs to L^2 (-pi;pi) then the integral of this will ...
WebMar 24, 2014 · When defining a sequence x n = g ( x n − 1) (for some function g) and asking to show that { x n } is well-defined (since there is a root or a fraction somewhere in the definition), students often show that the sequence converges to something (under the assumption that it is well-defined) and do not see that they have to ensure that there is … In mathematics, a well-defined expression or unambiguous expression is an expression whose definition assigns it a unique interpretation or value. Otherwise, the expression is said to be not well defined, ill defined or ambiguous. A function is well defined if it gives the same result when the representation of the input is changed without changing the value of the input. For instance, if takes real numbers as input, and if does not equal then is not well defined (and thus not a function…

WebAug 12, 2024 · The second axiom is what makes a function "well-defined." There is no proof needed to show that "functions are well-defined," (they are well-defined by definition!) BUT quite often we have a rule we invented making a relation, and we need to prove "this relation has properties 1 and 2, so it is a well-defined function." ...
