There are many different ways to indicate the operation of differentiation, also known as finding or taking the derivative. The choice of notation depends on the type of function being evaluated and ...

We investigate the distribution of the logarithmic derivative of the Riemann zeta-function on the line ℜ(s)=σ, where σ lies in a certain range near the critical line σ=½. For such σ, we show that the ...

Most conventional policy gradient reinforcement learning (PGRL) algorithms neglect (or do not explicitly make use of) a term in the average reward gradient with respect to the policy parameter. That ...
