When the values that a random variable $${X}$$ can take are $${x_{1}, x_{2}, \dots , x_{n}}$$, the expected value $${E(X)}$$ is defined by the following formula E(X)= \sum _{k=1}^{n}x_{k}P(X=x_{k}) ...

Abstract: This paper considers the problem of minimizing the expected value of a (possibly nonconvex) cost function parameterized by a random (vector) variable, when the expectation cannot be computed ...

Abstract: The law of large numbers in probability theory states that the average of random variables converges to its expected value in some sense under some conditions. Sometimes, random factors and ...

In the study of the spectra of power-law graphs, there are basically two competing approaches. One is to prove analogues of Wigner's semicircle law, whereas the other predicts that the eigenvalues ...
